Magnesium is one of the most active minerals in the body, activating and being a cofactor in over 350 different enzyme reactions, it is involved in nerve function and energy metabolism, and the lack of magnesium can cause a number of issues. Magnesium is easily expelled from our bodies. Consuming lots of caffeine, exercise, physical, psychological, emotional stress and antibiotics can deplete your body's magnesium stores. The human gut lacks the facilities to absorb the minerals adequately, because of this, magnesium must be chelated, bound to an organic substance to improve digestion. There are many different chelating agents for magnesium, each one offers a different percentage of bioavailability. We choose to provide magnesium citrate because using citric acid as the chelating agent provides the highest percentage of bioavailability at nearly 90%. It is safe and natural, a derivative of naturally occurring earth salts, and used in lots of food and other supplements. Among many of magnesium's benefits, its presence is most strongly felt and needed in bones and muscles. 60% of your body's magnesium can be found in your skeleton and nearly 10% more can be found in skeletal cells. Magnesium improves the body's ability to absorb and use calcium and potassium, and with inadequate amounts of magnesium, your body will begin to remove calcium from bones and deposit it into muscles and soft tissue. Low magnesium can also cause neuropeptides and neurotransmitters to become overactive, which may cause poor joint mobility and an increase in bone, muscle, and joint pain.
