Magnesium is a mineral responsible for many biochemical processes in the body. It activates essential enzymes, functions in the metabolism of nucleic acids and miscs, aids in various hormonal activities, and is required for many body processes such as energy production. It also transports sodium and potassium across cell membranes, affects calcium levels in cells, aids in muscle contractions, binds calcium to tooth enamel, used in the contraction and relaxation of muscles such as the heart, is required for the transmission of nerve impulses, and is required for growth and repair.
Plant sources of magnesium include brown rice, soybeans, nuts, wholegrains, dark chocolate, avocados, bananas, wheat germ, and whole-wheat bread. Animal sources include cod, halibut, herring, mackerel, shrimp, swordfish, and dairy products.
Magnesium deficiency is more common amongst those that are old, have high stress levels, and consume a lot of tea and coffee. Symptoms include muscle contractions, hyperactivity in children, blood pressure problems, poor circulation, memory problems, convulsions, irritability, nervousness, cramps, hypertension, skin problems, anemia, PMS, menstrual pain, and kidney stones.
