About Magnesium

Promotes Healthy Nerves & Supplements the Body's Natural Minerals.

Magnesium is an vital mineral involved in nerve and muscle function, and it promotes the absorption and metabolism of calcium. Magnesium activates the enzymes necessary for a number of physiological functions, including neuromuscular contractions, heart and cardiovascular function, and the regulation of the acid-alkaline balance in the body. It is necessary for the metabolism of carbohydrates, amino acids and fats; also for energy production, and the utilization of calcium, phosphorus, sodium, and potassium. This vital mineral also helps utilize B-complex vitamins, vitamin C, and vitamin E. Douglas Lab Magnesium is highly bioavailable, supporting the metabolism and utilization of many essential nutrients and the proper functioning of important enzymatic and physiological functions. Magnesium plays a large role in the utilization of potassium; it modulates a primary potassium transport system in and out of individual cells, and is crucial in preventing intracellular potassium loss. Magnesium provides for optimum utilization of potassium and protects stores of potassium from depletion.

Scientific Studies

A double-blind study found that regular use of magnesium helps prevent migraine headaches. In this 12-week trial, 81 people with recurrent migraines were given either 600 mg of magnesium daily or placebo.1 By the last 3 weeks of the study, the treated group's migraines had been reduced by 41.6%, compared to a reduction of 15.8% in the placebo group.

Magnesium works with calcium and potassium to regulate blood pressure. Several studies suggest that magnesium supplements can reduce blood pressure in people with hypertension,2-5

A double-blind placebo-controlled trial of 50 individuals with blockage in the arteries to the heart (coronary artery disease) found that supplementation with magnesium at 730 mg daily significantly improved exercise tolerance.6

A 6-month double-blind placebo-controlled study of 50 women with menstrual pain found that treatment with magnesium significantly improved symptoms.7
