Deuster, PhD, MPH Professor and Scientific Director CHAMP Objectives • Present picture of dietary supplement use among active duty personnel • Discuss concerns and red flags regarding dietary supplements • Describe nutrition and dietary supplements information associated with extreme exercise programs • Introduce new DoD classification system for dietary supplements Supplement Use by Age 30 17 to 25 Yrs Percent of Sampe (%) ** 26-34 Yrs 25 •35 Yrs 20 ** 15 ** 10 5 0 Body Building Performance Enhancing Weight Loss Supplement Use by Gender Percent of Sampe (%) 30 25 Male Female ** 20 15 10 ** 5 ** 0 Body Building Performance Enhancing Weight Loss Supplement Use by Service Percent of Sampe (%) 30 ** 25 Army Air Force Marines Navy ** 20 15 10 ** 5 0 Body Building Performance Enhancing Weight Loss Percent of Sampe (%) Body Building Supplements and Drinking 30 ** 25 Abstain Light Moderate Mod/Heavy Heavy 20 ** ** ** ** 15 10 5 0 Body Building Performance Enhancing Weight Loss US Army Survey • 9.1% took combination products: CellTech, Hydroxycut, Nitrotech, or Xenadrine) • 37.5% took multivitamins/multiminerals • 18.7% took protein and amino acids • 17.9% used single vitamins/minerals • 8.3% used herbal supplements • 2.7% used steroid analogs Lieberman et al. AJCN. July 28, 2010 Reasons for Use US Army Survey • • • • • 64.2% to improve general health 31.1% to increase energy 24.9% to increase muscle strength 16.7% to enhance performance Persons who strength trained were 8.3 times more likely to take protein and amino acid products Lieberman et al. AJCN. July 28, 2010 • • • • • • Characteristics of Body Building Supplement Users 18 to 25 yo A Marine Unmarried BMI 25 – 30 Physically active Heavy drinker Stephens et al. found an association between the use of ergogenic supplements and specific health risk behaviors. Hidden Ingredients Dietary supplements deliberately contaminated with: – Prescription drug ingredients – Ingredients under clinical investigation w/an IND – Ingredients approved as drugs in other countries – Ingredients removed from US market for safety reasons – Analogues of prescription drug ingredients – Controlled substances 12 Red Flags • Product categories: weight loss, performance enhancing, bodybuilding • Label claims like: – Alternative to [approved drug products] – Do not take if you have any medical condition, if you are taking any prescription medications, or if you are pregnant – May cause positive result in drug test • Labels primarily in a foreign language • Directions and warnings resembling FDA approved drug products Trends from Iraq • Warfighters are taking mostly combinations of or “stacked” products readily available at exhanges on base • “RIP-ITs” are stocked at all DFACs (energy drink supplements) • Most readily available products: NO products Rip It® 16 oz Energy Drink Side Effects Observed in Theatre • Multiple case reports of syncope, palpitations and lightheadedness from NO products • Warfighters who become dehydrated appear at increased risk of side effects from caffeine and other vasoactive components • Case reports of liver toxicity, possibly secondary to NO products • Rhabdo also seen, but no clearly identifiable supplement connection: possibly secondary to heat, dehydration and vasoactive components Various Programs • • • • • P90X CrossFit TRX® Military Athlete Gym Jones P90X Multiple supplements promoted Nutritional Guideline: Military Athletes • 6 Days a Week: – Eat lean meat, vegetables, fruit, nuts, seeds, and drink water. – Don't eat carbs (bread, spuds, rice) or sugar. • 1 Day a Week: – Cheat like a mother! – Beer, pizza, ice cream - you name it! Supplement Guideline: Military Athletes • Supplement diet with protein shakes & creatine to improve strength & recovery – Whey protein is best: Key ingredient is Leucine – Drink 10 min before & 15 min after training – Creatine - Take 20-25 grams/day for 5 days, then continue with 5 grams/day afterward • β-Alanine: Take to decrease fatigue, improve recovery, cut body fat and increase lean body mass CrossFit • No products promoted - but http://www.nastyenergy.com/ TRX® • Partners with Precision Nutrition – No supplement promotions found, but must be member to access information Gym Jones • No products promoted • Blogs on nutrition Gym Jones • Drink solution containing 88-90% carbs and 10-12% protein – Several supplements on the market that fit this profile. • Check ingredients to learn protein source – Whey peptides are ideal for recovery • Glutamine contributes to ammonia burden – Soy protein does not readily produce ammonia Proposed DoD DS Classification System • Combines potential benefit with probability of adverse event to estimate risk • Can be used to assess acceptability of risk • May be used to prioritize resources, develop educational materials, and standardize response actions • Can be revised as new evidence and/or adverse events emerge Dietary Supplement Risk Matrix Safety Benefit Minimal Concern High Potential Moderate Potential 1-Safe 3-Safe Low Moderate Concern Concern High Concern 2-Safe 7-Use w/ 9-Do Not Caution Use 4-Safe 8-Use w/ 11-Do Caution Not Use Low 5-Use w/ 6-Use w/ Potential Caution Caution 10-Do Not Use 12-Do Not Use http://www.humanperformanceresourcecenter.org/ Summary • Supplement use is problematic, particularly in the deployed setting • Body building and performance enhancing are primary supplements of concern • Supplements co-exist with HIT programs • Some HIT programs promote supplements that could be harmful, especially in the deployed setting Protein/Creatine/Amino Acids/Nitric Oxide, Arginine
