As many as 20 minerals play significant roles in the body. “Microminerals,” or minerals that the body only needs traces of, can fight off serious illness. These include copper, iodine, chromium, iron, fluorine, tin, zinc, nickel, vanadium, manganese, silicon, molybdenum, and selenium. “Macrominerals,” or minerals that the body needs large amounts of include magnesium, sodium, potassium, chlorine, phosphorus, calcium, and sulfur.

Zinc is responsible for helping metabolize proteins and keeping enzymes functioning. Copper is needed by enzymes for metabolizing. Iodine assists the thyroid gland in working properly. Calcium and phosphorus build bones and teeth. Iron delivers oxygen to the body’s cells. Potassium helps muscle contraction, maintains the fluid balance of cells, helps transmit messages through the body’s nerves, and keeps the kidneys and heart working correctly.

Vitamins and minerals not only help the body function, but they work to strengthen each other. The body absorbs iron through the help of vitamin C. Vitamin D helps the body absorb phosphorus and calcium. Vitamins D and K are the only vitamins the body can supply for itself. The skin creates vitamin D when it is exposed to sunlight. Vitamin K is produced by intestinal bacteria. Outside sources must supply the body with all other vitamins.
