Magnesium Supplements

Magnesium is a mineral needed by every cell of your body, as well as for more than 300 biochemical reactions in the body. Approximately 50% of total body magnesium is found in bone. The other half is found predominantly inside cells of body tissues and organs. The body works very hard to keep blood levels of magnesium constant, yet only 1% of your body’s total magnesium is found in the blood1. Magnesium has been linked to a wide range of vital health functions and is a mineral that is important to help maintain good cardiovascular health and proper muscle function.
