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. Reacted Magnesium Powder delivers 300 mg 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. In addition, the chelated form of magnesium bisglycinate used in this formula is gentle on the stomach. Research has demonstrated this form to be well-tolerated, causing less laxation potential than other forms of magnesium, such as oxide.
