The Regulatory System of Herbal Mushroom Antrodia cinnamomea Products Used as Dietary Supplements and NDIs in the United States 美國對牛樟芝產品作為膳食補充劑及新膳食成分的法規系統 Shung-Chang Jong, Ph.D.鍾順昌 Consultant for Global Affairs, Director Emeritus of Microbiology ATCC, Manassas, VA 20110-2209, USA. sjong@atcc.org; www.atcc.org Abstract Antrodia cinnamomea, commonly called “Niu-Chang-Chih” by indigenous communities, is a rare herbal mushroom known only from Taiwan. The mushroom is popular in folk medicine, as it is used in treatments of numerous ailments due to the presence of diverse biologically active compounds. Its presence in nature is restricted to the tree Cinnamomum hanehirae, a species of cinnamon that grows at the altitude between 450-2,000 meters in mountain ranges. Because of its host specificity and scarcity in nature, this mushroom has become very expensive as medicinal material with prices up to US$44,000 per kilogram of good quality fruiting bodies collected from nature. The United States is the world’s largest healthcare market with annual sales of dietary supplement (DS) products approximately $23.7 billion in 2007 and the U.S. Government Accountability Office (GAO) estimated 75,000 DS products in the marketplace. It is critical for Niu-Chang-Chih DS manufacturers and exporters in Taiwan to understand the relevant U.S. federal laws and regulations if they are to establish long-term positions in the healthcare marketplace in the U.S. The regulation of foods and food ingredients is governed by various statutes enacted by the U.S. Congress. Pursuant to the Federal Food, Drug and Cosmetics Act (FDCA) and accompanying legislations, the Food and Drug Administration (FDA) has authority to oversee the safety and quality of substances sold as foods in the U.S. and to monitor claims made in labeling both the composition and the health benefits of foods. The 1994 Dietary Supplement Health Education Act (DSHEA) created a regulatory framework for dietary supplements (DSs) that included provisions establishing current good manufacturing procedures (DS CGMP), mechanisms for pre-market safety notifications for new dietary ingredients (NDIs), and a mechanism for establishing claims used in product labeling. All herbal mushroom Niu-Chang-Chih products used as DSs and NDIs are carefully regulated by U.S. federal authorities to ensure that they are safe to eat and are accurately labeled in the marketplace. Although Taiwan has created a regulatory framework specifically designed for health foods since 1999 (under the Health Food Control Act of 1999), Niu-Chang-Chih DS manufacturers in Taiwan that intend on exporting their products to the U.S. should carefully review their operating procedures to ensure that they comply with the regulatory requirements established by the FDA to meet standards as well as the expectation of U.S. consumers.

Introduction The herbal mushroom Antrodia cinnamomea Chang et Chou (1994), commonly called “Niu-Chang-Chih” by local communities, is hailed as a national treasure in Taiwan. In the wild, the rare and unique herbal mushroom grows solely on the tree Cinnamomum hanehirae Hayata, a species of cinnamon that grows at the altitude 450-2,000 meters above sea level in the mountainous terrain. It has long been used in folk medicine as an antidote for alcohol, food and drug intoxication, as an anticancer agent in liver cancer, and in the treatment of numerous ailments, such as diarrhea, abdominal pain, hypertension and skin itching. Like other medicinal mushrooms, the mushroom contains many biologically active ingredients that are believed to exhibit effects of purifying the blood, removing toxic substances, toning kidneys, protecting the liver, regulating intestines, strengthening the heart, adjusting blood pressure, anti-bacteria, resisting cold, suppressing cough, eliminating sputum, alleviating pain, tranquilizing, anti-cancer, relieving tumor, expelling toxin, and anti-fatigue. For use as specific dietary ingredients (DIs), many Niu-Chang-Chih products have been prepared through separation, extraction, and filtration from fruiting bodies cultivated or collected from the wild. Large scale extraction can be obtained from in submerged liquid bioreactors or from solid state fermentation on grain substances. They are sold in the form of dried fruiting bodies and biomass, pill, softgel, gelcap, capsule, tablet, powder and liquid. Today a wide variety of Niu-Chang-Chih products are widely available in Taiwan as dietary supplements (DSs) in health food stores, supermarkets, drug and national discount chain stores, as well as through the Internet, TV programs, mail-order catalogs, and direct sales. However, rapid technological advances and the expansion and globalization of the health food industry present significant challenges, not the least of which, are regulatory variances between countries active in the marketplace. The United States is the world’s largest healthcare market, with annul sales of DS products approximately $23.7 billion in 2007 and the U.S. Government Accountability Office (GAO) estimated 75,000 DS products are available on the market. About half of adults in the U.S. report regularly using DSs, and the DS industry and market is growing every year. It is critical for Niu-Chang-Chih DS manufacturers and exporters in Taiwan to understand the relevant U.S. federal laws and regulations if they are to establish long-term positions in the healthcare marketplace in the United States. II. U.S. Federal legislations regulating food and dietary supplement products in marketplace The U.S. currently leads all other countries in the extent and details of its food safety legislation. Compliance with the following specific laws and regulations is an important factor in the availability of safe, wholesome, and properly labeled food/dietary supplement products in marketplace in the United States. (1) Federal Food, Drug and Cosmetics Act (FDCA), 1938 (2) Food Additive Amendments Act (FAAA), 1958 (3) Fair Packaging and Labeling Act (FPLA), 1966 (4) Nutrition Labeling and Education Act (NLEA), 1990 (5) Dietary Supplement Act (DSA), 1992 2 (6) Dietary Supplement Health and Education Act (DSHEA), 1994 (7) Public Health Security and Bio-terrorism Preparedness and Response Act (the Bioterrorism Act), 2002 (8) Dietary Supplement and Nonprescription Drug Consumer Protection Act (DSNDCPA), 2006 (9) Food and Drug Administration Modernization Act (FDAMA), 2007 (10) Dietary Supplement Current Good Manufacturing Practices (DS CGMP), 2007 (11) Food Safety Modernization Act (FSMA), 2010 The Federal Food, Drug, and Cosmetic Act (FDCA) of 1938, which replaced the 1906 Pure Food and Drugs Act, is the basis of U.S. food and DS supply. It broadened prohibition against economic “adulteration” and authorized the establishment of “standards.” The FDCA requires the label of every processed packaged food/DS to contain the name of the food, its net weight, the name and address of the manufacturer or distributor, and for certain products, a list of ingredients. It prohibits labeling statements that are false or misleading. Although the FDCA has been amended a number of times since its passage, its basic principles to prevent the “adulteration” and “misbranding” of food/dietary supplement (DS) remain essentially unchanged. A “food additive” as defined by the FDCA is a substance that may become component of a food or affect the characteristic of a food but is not a GRAS substance (Generally Regarded as Safe), a prior sanctioned material, a pesticide chemical residue, or a color additive. The Food Additive Amendment Act of 1958 was a milestone in that it required “safety testing” for additives used in processed foods prior to their use and shifted the burden for conducting that testing from the government to the industry, and gave the FDA the authority for “premarket review and approval” of additives. Thus, premarket approval is not required if the proposed use of the substance is GRAS that is distinguished from a food additive based on the common knowledge about the safety of the substance for its “intended use.” GRAS status for a food ingredient can be achieved either through its extensive history of common use in food before 1958 or through published scientific evidence. Any food additive that is intended to have a technical effect in the food is deemed unsafe; and any food that contains an unsafe food additive is adulterated. Similarly, any substance that is added to food and imparts color to the food is a color additive. Unlike the definition for food additive, there is no GRAS exemption for color additives. Any food that contains an unsafe color additive is adulterated. The Fair Packaging and Labeling Act (FPLA) of 1976 was a step forward in regulating information on labels, particularly concerning the quantity of contents, in order to facilitate value comparisons. It applies to all consumer products in interstate commerce intended for retail. The Nutrition Labeling and Education Act (NLEA) of 1990 amended the FDCA, reaffirming the FDA’s labeling initiative and establishing an explicit timetable for implementation. The NLEA required mandatory nutritional labeling for virtually all 3 food, including conventional foods and dietary supplements (DSs), standardized serving sizes, and the uniform use of health claims. According to the NLEA, the FDA was to determine what diet-disease relationships are adequately supported by scientific evidence and then promulgate regulations under which claims may be made for specific food products. The FDA proposed rules as required by the NLEA in 1991, and was about to publish final rules a year later when Congress published the Dietary Supplement Act (DSA) of 1992. The DS Act provided a one-year moratorium on application of the NLEA to dietary supplements and required the FDA to propose new rules on nutrition labeling of and nutrient content claims for DSs. Before the DS Act could be implemented, Congress intervened by passing the Dietary Supplement Health and Education Act (DSHEA) of 1994. The DSHEA created a new framework for the regulation of DSs, which signals a major departure from the well-established “food” versus “drug” dichotomy that guided the FDA policy with respect to such products for over fifty years. The DSHEA defined dietary supplements (DSs), set criteria for regulating labeling and claims, and established government agencies to serve as a watchdog over regulations of DS. DSs were no longer regulated like other products such as foods, drugs, food additives, GRAS ingredients, cosmetics, and medical devices, but rather they became a new category of food substances or “dietary supplements (DS).” The goals of DSHEA are to promote healthful diets and thereby possibly mitigate the need for expensive medical procedures; to empower consumers to make choices about preventive health care programs based on data from scientific studies of health benefits related to particular DSs, and to improve the flow of safe products to consumers. The Public Health Security and Bio-terrorism Preparedness and Response Act (the Bioterrorism Act) of 2002 requires registration of facilities with the FDA and recordkeeping regulations extend to those that transport, distribute, receive, or import foods/dietary supplements. The Dietary Supplement and Nonprescription Drug Consumer Protection Act (DSNDCPA) of 2006 requires a manufacturer, packer, or distributor whose name appears on the label of a DS, known as “responsible person”, to report a serious event to FDA within 15 days of receipt of the information. The Food and Drug Administration Modernization Act (FDAMA) of 2007 prohibits the addition of drugs or biologics to food and to authorize the creation of a “reportable food registry” collect information about any food/DS that may pose serious health risks. The Dietary Supplement Current Good Manufacturing Practices ( DS CGMP) of 2007 requires that proper controls are in place for DSs so that they are processed in a consistent manner, and meet “quality standards” through manufacturing, packaging, labeling, and storing of DS products. The Food Safety Modernization Act (FSMA) of 2010 was signed into law by President Obama on January 4, 2011. The law is the most sweeping reform of food safety laws in more than 70 years. It shifted the focus of FDA away from responding to problems and toward prevention. One of the law’s priorities is creating a new system of import oversight. Increasing globalization of food/DS supply is one reason given for why 4 FSMA was needed. However, the FDA currently inspects less than one pound in a million of imported foods/DSs (New York Times). III. Statutory definition of dietary supplements and dietary ingredients set by U.S. Congress through DSHEA of 1994 The Institute of Medicine of the U.S. Academy of Sciences has defined “functional foods” as those that “encompass potentially healthful products, including any modified food or food ingredient that may provide a health benefit beyond the nutrients it contains.” The term “functional food” comes in a plethora of name forms such as “dietary supplement”, “food supplement”, “nutritional supplement”, “nutraceutical, health food”, “medical food”, “vita food”, “designer food”,” natural health product”, and “pharmafood” in the U.S. marketplace. “Functional foods” essentially are “conventional foods” that have ingredients put in them for which health-related claims are made. Under U.S. laws, there are no recognized “functional foods” or “traditional medicines.” There are, however, “dietary supplements.” Thus, the term “dietary supplement” (DS) is now being more widely accepted and recognized by consumers. Through DSHEA, DSs are regulated as a special category of food for almost all purposes under FDCA. But, there are “safety” and “claims” provisions relating DSs that are different than those that apply to other food categories. The DSHEA expands the definition of DSs to include herbs and other botanicals in addition to vitamins, minerals, amino acids, concentrates, metabolites, constituents, extracts or combinations of any of these ingredients. In addition, a DS is limited to products that are intended for “ingestion” in tablet, capsule, powder, softgel, gelcap, or liquid, or other form, that are not represented as a “conventional food” or as a sole item of a meal or of the diet, and are labeled as “dietary supplements.” The DSHEA also defined both the term “dietary ingredient” (DI) and “new dietary ingredient (NDI) as components of DSs. An NDI is one that meets the definition for a DI and was not marketed in the U.S. prior to October 15, 1994 and does not include any old DI which was marketed in the U.S. prior to October 15, 1994. Understanding the legal distinction between “old” and “new” dietary ingredients/supplements is imperative for any company marketing a Niu-Chang-Chih DS product in the U.S. marketplace. DSHEA classifies a DS as adulterated if it “presents a significant or unreasonable risk of illness or injury.” In DSHEA, an “unreasonable risk” has a meaning independent from a “significant risk.” Thus, “unreasonable risk” is a distinct term and requires more than evaluation of the significance of risk. In other words, an “unreasonable risk” is relative to the circumstances; the potential risk is more “unreasonable” if the potential benefit is smaller. In January of 2014, the FDA released a “Guidance for Industry: Distinguishing Liquid Dietary Supplements from Beverages.” The purpose of the guidance is to, “to help dietary supplement and beverage manufacture and distributors determine 5 whether a product in liquid form is properly classified as a dietary supplement or as a beverage. The guidance discusses a combination of factors for consideration, which includes (1) Product or brand name, (2) product packaging, (3) serving size and total recommended daily intake, (4) composition, (5) recommendations and directions for use, (6) statements or graphic representations in labeling or adverting, (7) other marketing practices. The guidance also pays special attention to powers, concentrated liquids and effervescents that are added to water or other liquids. IV. Premarket notification for a new dietary ingredient (NDI) required by FDA Any DS that contains an NDI is deemed adulterated unless the manufacturers, marketers or distributors submit information to FDA at least 75 days prior to the introduction of an NDI into the market with sufficient information qualifying the safety of the NDI. Generally, the “pre-market safety notification” must include the history of use or other evidence of safety establishing that the NDI will reasonably be expected to be safe under the conditions of use recommended or suggested in the labeling. The scientific name of the NDI must include the “Latin binomial” (including the author) if the ingredient is a botanical or microbe when filing an NDI submission. FDA uses the NDI notification process as its safety gatekeeper to monitor and evaluate the safety of the NDI contained in DSs. Any DS containing ingredients that fail to meet the NDI review process is deemed unlawfully marketed and prohibited from sale until the NDI requirements have been met. The Division of Dietary Supplement NDI Review Team in the Office of Nutrition, Labeling and Dietary Supplements at the Center for Food Safety and Applied Nutrition (CFSAN) reviews NDI notifications. Any DS that contains an NDI is deemed adulterated unless it meets one of the following requirements: (1) It is a DS that contains only DIs that have been present in the food supply as an article used for food in a form in which the food has not been chemically altered. Food is not chemically altered if in processing there is minor loss of volatile components, dehydration, lyophilization, milling, tincture or solution in a water slurry, powder, or solid in suspension. (2) There is a history of use or other evidence of safety establishing that the DI when used under the conditions recommended or suggested in the labeling of the DS will reasonably be expected to be safe. The overall regulatory status of a DS is affected by the regulatory status of each individual DI. It is the responsibility of the manufacturer of any DS products to ensure that all ingredients used are of food-grade purity and comply with specifications and limitations in all applicable authorizations. To determine compliance, each authorization must be composed of three parts: 6 (1) identity of the substance (e.g., chemical, herbal/botanical, and microbiological) used as a DI in a DS, (2) specifications including purity and physical properties, and (3) limitations on the conditions of use. FDA instituted this proceeding to help the DS industry comply with the DSHEA. V. Regulations for permissible claims and labeling of dietary supplements required by FDA FDA is tasked with overseeing claims on product labeling, including all labels and other written, printed, or graphic matter upon any article or any of its containers or wrappers, or accompanying such article. The label of a DS may contain one of the following three types of claims: (1) Health claim describes a relationship between a DS ingredient, and reducing risk of a disease of health-related condition. (2) Nutrient content claim describes the relative amount of a nutrient or DS substance in a product. (3) Structure/function claim is a statement describing how a product may affect the organs or systems of the body and it can not mention any specific disease. Different requirements apply to each type of claim. According to DSHEA, DS labels can carry these claims without obtaining “pre-marketing authorization” from the FDA. The manufactures are responsible for ensuring the accuracy and truthfulness of such label claims that are not approved by FDA. But for structure/function claims, manufacturer must provide FDA with the text of the claim within 30 days of putting the product on the market. Product labels containing such claims must also include a disclaimer “prominently displayed and in boldface type” that states: “The statement has not been evaluated by FDA. This product is not intended to diagnose, treat, cure, or present any disease” DSHEA essentially gives the DS manufacturer freedom to (1) market more products as DSs, and (2) provide information about the benefits of their products in product labeling. FDA regulations require that the term “dietary supplement” appears as part of the statement of identity on the Principal Display Panel (PDP) of a DS product. DS labels must also display a fact panel that identifies each DI and the amount of its DIs used to manufacturing their products. They are further responsible for determining that any representations or claims they make about their products are supported by adequate evidence to show that they are not false or misleading. VI. Regulations for advertisements of dietary supplements required by FTC and UPS The U.S. Federal Trade Commission (FTC) is tasked with overseeing the claims in the advertising of DSs, including print, broadcast ads on radio and TV, informercials, catalogs, and similar direct marketing materials. The function of the FTC is to develop recommendations for the regulations of label claims and statement for DSs and to 7 evaluate how best to provide truthful, scientifically valid, and not misleading information to consumers so that such consumers may make appropriate health care choices for themselves and their families The authority of the FTC is (1) to challenge and stop advertising that is not sufficiently substantiated; (2) to negotiate a consent order for a company to change or fix its promotional marketing or advertising practices; and (3) to seek substantial civil penalties for violations of trade regulation rules or violations of cease and desist from orders. FDA works closely with the FTC in this area, but FTC’s work is directed by different laws. Marketing on the Internet is subject to regulation in the same manner as promotions through any other media. Advertising through promotional printouts delivered by the U.S. Postal Service (UPS) are regulated under different laws and are subject to regulation by the U.S. Postal Inspection Service. VII. Registration of food facilities and prior notice of imported food shipments required by FDA through the Bioterrorism Act of 2002 The Bioterrorism Act of 2002 directs FDA to take additional steps to protect the public from a threatened or actual terrorist attack on the U.S. food/DS supply and other foodrelated emergencies. To carry out certain provisions of the Bioterrorism Act, FDA has established new regulations requiring that: (1) food facilities are registered with FDA, and (2) FDA be given advance notice on shipments of imported food. The Act requires that domestic and foreign facilities and manufacture, process, pack, or hold food (including DSs and DIs) for human or animal consumption in the U.S. to register with FDA by December 12, 2003. Under FDA’s current registration regulations, food facilities that are required to register include manufacturers, processors, warehouses, storage tanks and grain elevators. The Act also requires every food company to be able to trace its products both one step forward and one step back, from company to company, through the supply chain. VIII. Serious adverse event reporting law (SAER) effective December 2007 Mandatory reporting to FDA of serious adverse events (SAER) is now required as a result of the enactment of the “Dietary Supplement and Non-prescription Drug Consumer Production Act” (DSNDCPA), signed into law on December 22, 2006, effective December 2007). The law requires manufacturers, packers, or distributors of DS products to submit reports to FDA about all serious adverse events involving such products based on specific information that they receive from the public. The term “serious adverse event” is an adverse event that (1) results in death, life-threatening, inpatient hospitalization; a persistent or significant disability or incapacity; or a congenital abnormally or birth defects; and (2) requires, based on reasonable medical judgment, a medical or surgical intervention to prevent an outcome described under subparagraph. 8 The manufacturer, packer, or distributor of a DS whose name appears on the label of a DS marketed in the U.S. must submit to the FDA an SAER no later than 15 business days after the report is received through the address or phone number described on the label. The responsible person shall submit to the FDA any new medical information related to a submitted SAER that is received by the responsible person within one year of the initial report. FDA is now accepting online submission of voluntary and mandatory DS adverse event reports. The new submission capability is available through the DHHS Safety Reporting Portal (http://www.safetyreporting.hhs.gov). Reporting of DS adverse events is critically important in protecting consumers’ health and safety. The FDA routinely monitors the marketplace. However, with more than 75,000 DSs now on the market and no product specific registration requirement, SEAR reporting is invaluable in identifying harmful products in the marketplace. IX. Current good manufacturing practice requirements for quality control of the safety and purity of dietary supplements (DS CGMP) established by FDA in 2007 It is difficult to determine the quality of a DS product from its label. The degree of quality control depends on the manufacturer, the supplier, and others in the production process. As part of DSHEA, Congress gives FDA the express authority to issue regulations establishing “Current Good Manufacturing Practices” (CGMP) for DS manufacturers. On June 25, 2007, the FDA issued the DS CGMP rule establishing requirements for the production of DSs, and an identity testing Interim Final Rule (IFR) that set forth a procedure for requesting an exemption from the requirement in the DS CGMP rule for the manufacturer to conduct at least one appropriate test or examination to verify any dietary ingredient that is a component of a dietary supplement. The DS CGMP and the identity testing interim final rule were effective as of August 24, 2007, establish industry-wide standards for both domestic and foreign companies. The principal goals of the DS CGMP regulations are to ensure the quality, safety and purity of DS products. The DS CGMPs have been seriously implemented only since 2010. Based on audits completed by FDA’s compliance division in 2011 and 2012, however, it was estimated that nearly 70% of DS manufacturers have run afoul of the FDA’s manufacturing regulations over the last five years. X. Requirements for dietary supplement manufacturers under the DS CGMP rule The CGMP rule provides standards that affect the products, processes, and people involved in DS manufacturing. These standards support overall quality of the finished products under the premise that “quality” is built into the manufacturing process. The focus of CGMP regulations is on process controls to ensure that the desired outcome is consistently achieved, and not on the inherent safety of the ingredients used, which is matter of other statutes. The rule requires that each manufacturer focus on “Hazard Analysis and Critical Control Point” (HACCP) to establish adequate controls over 9 the production process and specifications for their products to ensure that they consistently and reliable manufacture what is intended. However, there are no common or minimum requirements for quality. The rule gives DS manufacturers freedom to decide: (1) their own specifications for identity, quality, strength, composition and absence of contaminants for components (dietary ingredients and others); in process materials, and finished DS products; (2) how to qualify their suppliers in order to avoid 100% testing of components (condition to accept “certificate of analysis”); and (3) on the quality of “reference materials” to calibrate analytical equipment and the use of analytical methods. A requirement of the Food Safety and Modernization Act of 2010 (FSMA) is amending CGMPs for food products to include “Hazard Analysis and Risk-Based Preventive Controls for Human Food” (HARPC) that focuses on preventing problems that can cause food borne illness. According to an FDA Fact-sheet, the HARPC rule would apply to many domestic and foreign firms that manufacture, process, pack or hold human food/DSs. These firms would be required to have written plans that identify hazards, specify the steps that will be put in place to minimize those hazards, identify monitoring procedures and record monitoring results and specify what actions will be taken to correct problems that arise. XI. Standards without standardization under the DS CGMP rule No legal or regulatory definition exists in the U.S. for standardization as it applies to DSs. Under the DS CGMP, FDA regulates only “quality and good manufacturing” but does not ensure standardization of the active ingredients. Also, FDA does not require manufacturers of DSs to assure that DS ingredients are safe and effective, only that they do not contain dangerous contaminants or impurities and a label to accurately reflect the ingredients in the finished product. Therefore, specifications for similar DS products can vary widely from manufacturer to manufacturer; and consumers would not know if two products containing similar ingredients and similar labels are subjected to a different set of “quality parameters.” Some manufacturers use the term “standardization” incorrectly to refer to uniform manufacturing practices; following a recipe is not sufficient for a product to be called standardized. Therefore, the presence of the word “standardized” on a DS label does not necessarily indicate product quality. XII. Use of “certificate of analysis” and standard “reference materials” under the DS CGMP rule Since the active components of the botanical/herbal DSs are often not well defined, precise, accurate and rugged “analytical methods” and standard “reference materials” are essential for “verification of ingredient identity”, identifying and measuring contaminants, and measuring the amount of declared “ingredients in raw materials” and “finished products.” However, the CGMP rule does not apply to DI manufacturers or suppliers, but only to manufacturers who produce, package, or hold DSs. The 10 “certificate of analysis” (CoA) can be used as a bridge between suppliers of DIs and manufacturers of DSs. The CoA from suppliers is acceptable as proof of compliance with specifications established for DS components for (1) every test except identity for DIs, and (2) every test including identity for non-dietary ingredient components. “Component” is defined as “any substance intended for use in the manufacture of a DS, including those that may not appear in the finished batch of the DS.” The manufacturer must “qualify” its supplier, periodically reconfirm the findings in the CoA, and have knowledge of the tests upon which the certificate relied. The CGMP rule requires calibration of analytical equipment, for which “reference materials” (RS) are needed. The rule also gives freedom to DS manufacturers to set their own RSs and testing protocols. The rule, however, supports (but not requires) the use of compendia reference standards where they are available, e.g. ATCC (American Type Culture Collection), USP (U.S. Pharmacopoeia), NIST (National Institute of Standards and Technology, the NIH Dietary Supplement Methods and Reference Materials Program created in 2002. An overview of the NIH program is available in the May 2007 issue of “Analysis and Bioanalytical Chemistry” 389: 19-25. XIII. Exemption of 100% identity testing for a dietary ingredient under the identity testing Final Interim Rule (FIR) established by FDA in 2007 Because of the critical importance of ensuring the proper identity of DIs, the DS CGMP rule requires that each manufacturer conducts at least one appropriate test, or examination to verify the identity of any component that is a DI prior to use in the manufacturing process. This requirement for 100% identity testing of DIs applies to a manufacturer who purchases a DI from a DI supplier and who manufacturers its own DI for use in the manufacture of its DS. It is required for every DI, unless an FDA exemption is obtained pursuant to the petition procedure in the accompanying identity testing Interim Final Rule (IFR). Under this identity testing IFR, a manufacturer is granted an exemption from the requirement of the 100% identity testing only when a manufacturer petitions the FDA and the FDA grants such an exemption. The petition needs to provide data and information that are specific to each DI and each supplier. If a manufacturer is granted an exemption, the manufacturer would still responsible for ensuring the quality of the final DS products, and have to provide appropriate data and information in its petition declaring that using a proposed sampling plan would not result in ingredient variation provided by 100% identity testing. The approval of an exemption petition is only for the DI(s) and supplier(s), requested in the petition. Manufacturers may use one petition to request an exemption from the 100% identity testing for one or more DIs and one or more supplies. If the manufacturer changes DI(s) or supplier(s), or any other combination thereof, FDA’s approval would not apply to the particular changed DI. Manufacturer would return to 100% identity testing until it files a re-petition to FDA, and the re-petition is approved. 11 XIV. Regulatory requirements for Niu-Chang-Chih products used as dietary supplements and NDIs set by FDA govern by various laws enacted by the U.S. Congress DSs and their DIs derived from the herbal mushroom Niu-Chang-Chih present unique challenges for “safety evaluation” as they are a complex mixture of numerous chemical substances that exhibit compositional complexity and variation depending on many factors. In addition, the ingredients of these DS products are seldom completely chemically pure. The DS CGMP rule addresses the quality of manufacturing processes for DSs and the accurate listing of DIs. It does not limit consumer’s access to DSs; nor does it address the safety of their ingredients or their effects on health when proper manufacturing techniques are used. Therefore, DS CGMP regulations do not stop DS manufacturers from selling Niu-Chang-Chih DSs that are falsely labeled. U.S. Congress under DSHEA gives the FDA permission to stop a company from making a DS only when the FDA proves that the product poses a “significant risk” to the health of Americans. Although the FDA has created a regulation framework for DSs, similarities can be found between the regulatory framework for DSs and that for food as DSs are deemed as food. The following is a summary of the regulatory requirements set by the FDA pertaining to DSs from the herbal mushroom Niu-Chang-Chih. (1) Facility registration required (2) Ingredients conform to legal statute (3) 100% identity testing of every DI in the product required at each stage of the manufacturing process (4) Product forms limited to oral use intended for “ingestion” that is, to take into the stomach and gastrointestinal tract by means of enteral administration through the mouth (5) Labeled as such using the term “dietary supplement” and displaying a “fact panel” that identifies each DI and the amount of it contained in each serving of the product (6) The correct scientific name of the Niu-Chang-Chih used as a source of dietary ingredients must include “latin bionomial” (including author) (7) Adulterated if a significant or unreasonable risk of illness or injury is present (8) Safety data and information be submitted to FDA for “new dietary ingredients” (NDIs) at least 75 days before marketing (9) Health claims be substantiated by adequate evidence to show that the claims are not false or misleading (10) All production must comply with DS CGMP regulations to ensure quality throughout the manufacturing, packaging, labeling, and storing of DS products (11) Serious adverse events received be submitted to FDA no later than 15 business days (12) Advance notice on shipments of imported products required 12 Under the FDCA, the legal status of a DS product is dependent on whether it is offered for use in a “conventional food” or its use is as a “dietary supplement” or as a “dietary ingredient in a DS.” Because DSs are under the “umbrella” of foods, FDA’s Center for Food Safety and Applied Nutrition (CFSAN) is responsible for regulating DS ingredients and ensuring that those ingredients derived from the herbal mushroom Niu-Chang-Chih are as safe and lawful. How CFSAN regulates the use of a substance derived from Niu-Chang-Chih is determined by its “intended conditions of use.” CFSAN has an essential responsibility to take action against any unsafe Niu-ChangChih DS product after it reaches the market. Generally, manufacturers do not need to get CFAN’s approval before producing or selling DS products. The authority of the CFSAN to regulate the DS industry includes: (1) stop a company from selling any DS that is unsanitary or unsafe, (2) stop the sale of any DS that makes false or non-substantiated claims on its labeling, (3) stop the sale of any DS that poses “significant” or unreasonable risk of illness or injury, and (4) oversee mandatory adverse event reporting by DS manufacturers. Niu-Chang-Chih Products intended to diagnosis, mitigate, treat, cure, or prevent disease in man or animals are regulated as drugs that must be proven safe and effective in FDA-approved and reviewed clinical trial. Drugs are regulated by the FDA’s Center for Drug Evaluation and Research (CDER). XV. Additional U.S. federal agencies involved in advancing scientific base of knowledge making it possible to better evaluate the safety and effectiveness of dietary supplements The NIH Office of Dietary Supplements (ODS) was created by DSHEA (1994) in the Office of Disease Prevention at NIH, which began operations in November 1995. ODS is directed by DSHEA to conduct and coordinate scientific research relating to DSs within NIH, to coordinate funding for such research, to compile a database of such research, and to serve as the principal advisor to HHS, NIH, CDC, and FDA on issues relating to safety, benefits, and labeling of DS. The duties of the ODS are to strengthen knowledge and understanding of DSs by (1) evaluating scientific information, (2) stimulating and supporting research, (3) disseminating research results, and (4) educating the public to foster an enhanced quality of life and health for the U.S. population. “Traditional medicine” is used as a comprehensive term to refer both to traditional medicine systems such as Traditional Chinese Medicine (TCM) and to various forms of the indigenous medicine being practiced traditionally by indigenous populations in the world. Traditional medicine that has been adopted by other populations outside its indigenous culture is often termed “complementary and alternative medicine (CAM). The NIH National Center for Complementary and Alternative Medicine (NCCAM) is to explore CAM healing practices in the content of rigorous science, to trains CAM 13 researchers, to provide accurate information about CAM, and to help the public and health professionals understand which CAM therapies have been proven to be safe and effective. In response to a Congressional mandate, in 1999 the ODS initiated the Botanical Research Centers Program (BRC) in partnership with other NIH institutes/offices including NCCAM, National Institute of Environmental Sciences (NIES), National Institute of General Medical Sciences (NIGMS), NIH Office of Research on Women’s Health (ORWH) and National Cancer Institute (NCI). The BRC program for 2010-2015 includes the following grantee institutions: •Pennington Biomedical Research Center, Louisiana State University •University of Illinois at Chicago •University of Illinois at Urbana-Champaign •University of Missouri •Wake Forest University The issue of safety is particularly critical given how little information is available on the toxicity of the herbal/botanical products in the healthcare marketplace in the U.S. The National Toxicology Program (NTP) is a federal interagency program established in 1978, as a cooperative effort to coordinate toxicology testing programs within the federal government, strengthen the science base in toxicology, develop and validate improved testing chemicals to health, provide information about potentially toxic chemicals to communities, and the public. The three agencies that form the core of the NTP are the National Institute of Environmental Sciences of the NIH (NIEHS/NIH), the National Institute of Occupational Safety and Health of the Centers for Disease Control and Prevention (NIOSH/CDC), the National Center for Toxicological Research of the FDA (NCRT/FDA). Currently, both NIEHS and NCTP are actively working with ODS/NIH and CFSN/FDA to conduct research that addresses deficiencies in our knowledge about DSs/Dis and their potential toxicities. Reliable sources of information on DSs/DIs are important to evaluate the claims that are made about them, which are based on the results of rigorous scientific testing. To look for scientific research findings on the DSs/DIs, NCCAM/NIH, ODS/NIH and other federal agencies have free publications, clearinghouses, and information on their Websites. As a service of the National Library of Medicine (NLM), PubMed contains publication information and brief summaries of articles from scientific and medical journals (http://www.ncbi.nlm.nih.gov/pubmed). The PubMed Dietary Supplement Subset (PMDSS) is designed to help people search for academic journal articles related to DS literature. It succeeds the International Bibliographic Information on Dietary Supplements (IBIDS) database to continue the ODS mission to disseminate dietary supplement-related research results. The NLM’s MedlinePlus brings together authoritative information from NIH as well as other Government agencies and healthrelated organizations (http://www.medlineplus.gov). In addition, the NDL’s Dietary Supplement Ingredient Database (DSIS) has been developed by the Nutrient Data Laboratory (NDL) within the Agricultural Research Service (ARS) of the U.S. Department of Agriculture (USDA) in collaboration with ODS at NIH and other federal 14 agencies. It provides estimated levels of ingredients in DS products sold in the U.S. The NLM’s Dietary Supplements Label Database (DSLD) is a joint project of the ODS and NLM. It contains the full label contents from a sample of DS products marketed in the U.S. DSLD enables users to compare label ingredients in different brands. Its information also provides the “structure/function” claims made by manufacturers (http://dietarysupplements.nlm.nih.gov/dietary). The Computer Access to Research on Dietary Supplements (CARDS) database lists current and past grant projects focused on health effects of DSs funded by the USDA, the Department of Defense (DOD) and the Institutes and Centers of the NIH (http://libproxy.usc.edu/login?url). Patents contain the most complete and detailed information that is particularly important in relation to the commercial exploitation of invention in promoting technical innovation and the development of the Niu-Chang-Chih DS industry. The United Sates Patents and Trademark Office (USPTO) of the Department of Commerce (DOC) houses the Full Text and Image Database (PatFT) for all patents issued from 1976 to present (http://www.uspto.gov/patents/process/search). USPTO also maintains the Global Patent Search Network (GPSN) that enables users to search full texts of Chinese patent information from the State Intellectual Property Office (SIPO) of the People’s Republic of China (PRC). Documents available include published applications, granted patents and utility models from 1985-2012. XVI. Concluding remarks Today, dietary supplements (DSs) and dietary ingredients (DIs) in DSs are more strictly studied, regulated and monitored than at any other time in history in the U.S. The federal government regulates DS products through FDA govern by the DS provisions of the FDCA and accompanying legislations enacted by the U.S. Congress. The FDA’s primary mission is to ensure that the food/DS supply is safe for 300 million American consumers, and the American public fully expects its food/DS to be safe. The FDA characterizes Niu-Chang-Chih products according to their use, not according to their composition. When the intended use is to “promote” health, the agent is viewed as a dietary supplement; when the intended use is to “treat or prevent” a disease, the agent is considered to be a drug. Thus, FDA regulates DSs under a different set of regulations than those covering DS and drug products. DS and DI manufacturers and distributors are prohibited from marketing products that are “adulterated” or “misbranded.” FDA takes action against any adulterated or misbranded DS product after it reaches the market. The DS CGMP for quality controls of the safety and purity of DSs, detailed in the processing aspect of production, bear a stronger resemblance to drug CGMPs than they do to the rather general food CGMP. A key difference is that the DS CGMP does not require “process validation”, which is mandated by the drug CGMP. Instead, the emphasis in the DS CGMP is on documentation that relates back to the master batch record in terms of production, composition and processing steps. 15 Therefore, the enforcement of quality controls for the safety and efficacy of NiuChang-Chih DS products depends on the manufacturer, the supplier, and others in the production process. Under the rule of DS CGMP, Niu-Chang-Chih DS manufacturers must establish and implement, through written procedures, a production and process control system that covers every point, step, or stage in the manufacturing, packaging, labeling and holding operation and specifications for the identity, quality, strength, and compositions of their products and the absence of contaminants from the finished DSs. Niu-Chang-Chih DS manufacturers must enforce the quality requirements for their suppliers, periodically reconfirm the compositions in the CoA, and have knowledge of the tests, which makes it possible to avoid the 100% testing of components. Niu-ChangChih DS manufacturers also have the flexibility and responsibility to set their own standard RMs to validate specific measurement techniques and equipment. However, the DS CGMP rule does not apply to Niu-Chang-Chih DI manufacturers or suppliers, but only to DS manufacturers who produce, package, or hold DSs. Niu-Chang-Chiih DSs are not approved by the U.S. government for safety and effectiveness before they are marketed. If the DS contains a NEW ingredient, that ingredient will be reviewed by FDA (not approved) prior to marketing – but only for safety, not effectiveness. Thus, the amount of scientific evidence available for various Niu-Chang-Chih DS ingredients will vary widely. Scientists may use several approaches to assess the health “benefits” and “risks” of a Niu-Chang-Chih NDI or DS product. For example, scientists may investigate the history of use of people eating the DS product, conduct laboratory studies using cell or tissue cultures, experiment with animals, and determine the value of Niu-Chang-Chih DS products in maintaining good health based on the data from individual case reports, observational studies, and clinical trials in humans. The popular use of DSs from the unique herbal mushroom Niu-Chang-Chih as an adjunct to an improved quality of life or for their alleged medical benefits is increasing rapidly and is far ahead of the available scientific data on the efficacy and safety of these products. Its marketplace has grown categorically with new products finding their way into all retail channels. Researchers are studying many of these products in an effort to identify what ingredients may be active and understand their effects on health and patterns of use. With the multitude of products and brands available in the marketplace, there have been increasing concerns over the quality, safety and efficacy of these products. For those companies interested in long term success, careful and diligent research into the legal status of every dietary ingredient (DI) included in a dietary supplement (DS) should be an essential part of any new product development effort.
