Our unique magnesium formula combines four different chelates of magnesium for optimal absorption. Chelates are far better absorbed than the inexpensive magnesium salts. They are also better retained in body tissue. Magnesium, a mineral found abundantly in the human body, is involved in hundreds of essential biochemical reactions that keep the body functioning properly. It is one of the body’s most essential minerals and plays a role in protein synthesis, cardiovascular health, immune function, blood sugar management, and much more.
