Chelated Magnesium 100 mg - 100 Tablets

Chelated Magnesium

Chelated Magnesium by Douglas Labs - Highly absorbable chelated magnesium provides 100 mg elemental magnesium per tablet. Magnesium is involved in energy metabolism, and is notably important in the heart, skeletal muscles and nervous system.

Of the 20 to 30 grams of total body magnesium, about 40% is located in muscle and other soft tissues, and the remainder in bone. The concentration of intracellular magnesium is carefully regulated, and its alterations can have profound effects on cardiac and skeletal muscle physiology.

Healthy people require about 4.5 mg of dietary magnesium per kg body weight, or 280 mg for a 62 kg female and 350 mg for a 76 kg male. The U.S. RDA is 400 mg/day. The efficiency of magnesium absorption is a function of dietary intake. At very low intakes (less than 40 mg) 65-70% of dietary magnesium is absorbed, whereas at high intakes (1,000 mg) less than 15% is absorbed. Most people are expected to absorb about 30-60% at common levels of dietary magnesium.
