Magnesium is a mineral used by every organ in the body, especially the heart, muscles and kidneys. By some estimates, up to 80 percent of Americans are not getting enough of this key mineral. Magnesium insufficiency has been implicated in a wide range of health challenges. MAGNESIUM POWDER delivers 300 mg of magnesium bisglycinate chelate in a delicious, strawberry-lemonade flavored mix that can be added to any beverage. Magnesium bisglycinate was chosen for its proven enhanced absorption and is gentle on the stomach. Research has demonstrated this form of magnesium to be well-tolerated, causing less laxative potential than other forms of magnesium, such as oxide.
