Found in muscle tissue and is involved in many energy producing reactions in the body. Prevents heart arhythmias, associated with regulation of body temperature, neuromuscular contraction and synthesis of protein.
is second only to potassium in terms of concentration within the individual cells of the body. Magnesium's primary function is to activate enzymes. Approximately 60% of magnesium in the body is found in bone, 26% in muscle, and the remainder in soft tissue and body fluids. Metabolically active tissues such as the brain, heart, liver, and kidneys have the highest concentration of magnesium and depend on magnesium's critical role in energy production. Low magnesium levels can result in muscle spasms and weakness and may be connected to high blood pressure, depression and risk of heart attack. Most Americans consume a low magnesium diet because their diet is high in refined foods, meat, fish, dairy products, and the more commonly eaten fruits, which are all quite low in magnesium. Dietary sources of magnesium are tofu, legumes, seeds, nuts, whole grains, and green leafy vegetables.
