Introduction
Magnesium is involved in the interaction of more than 300 enzyme reactions in the body. It is necessary for the transmission of nerve impulses, temperature regulation, detoxification, energy production and the formation of healthy bones and teeth. It is also vital for cardiovascular health.

A U.S. Department of Agriculture study found that 75 percent of Americans do not get an adequate supply of magnesium in their diet. This is probably due to the absence of magnesium in many processed foods and the depletion of magnesium from agricultural soils in the U.S.

Good food sources include nuts, legumes, cereal grains, and dark green leafy vegetables.

Reported Uses
Magnesium is involved in a long list of body functions. First, it is required for metabolism of carbohydrates, proteins and fats. As part of its role in the activity of enzymes, it is involved in the transmission of nerve impulses and muscle contractions.

Magnesium plays a crucial role in maintaining the health of the heart and cardiovascular system. It helps thin the blood, relaxes blood vessels, lessens the risk of heart attack and more.(3),(4) It also moderately reduces blood pressure.(5),(6)

As a key player in calcium metabolism, magnesium is important for the health and development of bones and teeth. It helps maintain the integrity of bones and helps bind calcium to tooth enamel, thus creating a barrier to tooth decay.

Magnesium has targeted applications in no fewer than 12 health disorders. It may reduce the risk of developing asthma and is commonly used as part of an overall treatment program for asthmatics.(7),(8)

As mentioned, magnesium is used to prevent and treat cardiovascular diseases.(9),(10),(11) Magnesium supplementation may increase the survival rate of patients with congestive heart failure and it can help lower blood pressure.(12),(13),(14) One study demonstrated that induced magnesium depletion in postmenopausal women could result in poor cardiovascular functioning during exercise, including a greater need for oxygen and energy and an increased heart rate.(15)

Magnesium is also used to support health in people with diabetes,(16),(17) kidney stones,(18) osteoporosis,(19) PMS symptoms,(20) muscle cramps(21) and migraine headaches.(22),(23) Its energy-boosting qualities have been used to treat cases of chronic fatigue syndrome.(24)
