Battles over pure water or OIL?
One substance with hydrate your body ,
the other will dehydrate (a laxative)

Who has the ultimate control of these waterways?
Sparklettes Water
Dr. Gergens - SD Mesa College
The Crystal-Fresh® Drinking Water ingredient label
says the following:
“Drawn from our deep protected wells in Santa Ana, CA.
Purified using our Crystal-Fresh process, including
filtration, ozonation, reverse osmosis, and/or
dionization. Contains purified water and specially
selected minerals in nutritionally insignificant amounts
for great taste (sodium bicarbonate, magnesium chloride,
calcium chloride and sodium sulfate).

Lets learn to write the correct formulas for these substances
(sodium bicarbonate, magnesium chloride, calcium chloride and
sodium sulfate) that Sparkletts ® adds to it’s purified water
In “nutritionally insignificant amounts for great taste.”
