Mag-K

Magnesium is a mineral that is abundant in the body, and is a cofactor in more than 300 enzyme systems. These enzyme systems regulate many diverse reactions within the body including protein synthesis, muscle and nerve function, blood glucose control and blood pressure regulation. Magnesium is required for energy production and supports the structural development of bone and is required for the synthesis of DNA, RNA and glutathione. Magnesium also plays a role in processes important to nerve conduction, muscle contractions and normal heart rhythm.‡
Magnesium deficiency is not uncommon in the United States, and is particularly common among African Americans. The overall prevalence of magnesium deficiency in African Americans (predominantly female) was 20% based on a study of urban African Americans. Magnesium deficiency has also been noted in people with a history of alcoholism (6 times more likely), in people with chronic diarrhea, and 2/3 of people in intensive care.‡
Mag-K provides 200 mg of magnesium and 99 mg of potassium in bioavailable forms to support metabolism and energy production, support healthy bones, and promote muscle relaxation and cardiovascular health.‡
