-Vitamins Overview

Each vitamin has specific functions. You can develop health problems (deficiency disease) if you do not get enough of a particular vitamin.

Vitamin A helps in the formation and maintenance of healthy teeth, bones, soft tissue, mucous membranes, and skin.

Vitamin B6 is also known as pyridoxine. The more protein a person eats, the more vitamin B6 is needed to help the body use the protein. Vitamin B6 helps form red blood cells and maintain brain function, among other things.

Vitamin B12, like the other B vitamins, is important for metabolism. It also helps form red blood cells and maintain the central nervous system.

Vitamin C, also called ascorbic acid, is an antioxidant that promotes healthy teeth and gums. It helps the body absorb iron and maintain healthy tissue. It also promotes wound healing.

Vitamin D is also known as the "sunshine vitamin," since it is made by the body after being in the sun. Ten to 15 minutes of sunshine three times per week is enough to produce the body's requirement of vitamin D. This vitamin promotes the body's absorption of calcium, which is essential for the normal development and maintenance of healthy teeth and bones. It also helps maintain proper blood levels of calcium and phosphorus.

Vitamin E is an antioxidant also known as tocopherol. It plays a role in the formation of red blood cells and helps the body use vitamin K.

Vitamin K is not listed among the essential vitamins, but without it blood would not stick together (coagulate). Some studies suggest that it helps promote strong bones in the elderly.

Biotin is essential for the metabolism of proteins and carbohydrates, and in the production of hormones and cholesterol.

Niacin is a B vitamin that helps maintain healthy skin and nerves. It is also has cholesterol-lowering effects.

Folate works with vitamin B12 to help form red blood cells. It is necessary for the production of DNA, which controls tissue growth and cell function. Any woman who is pregnant should be sure to get enough folate. Low levels of folate are linked to birth defects such as spina bifida. Many foods are now fortified with folic acid.

Pantothenic acid is essential for the metabolism of food. It is also plays a role in the production of hormones and cholesterol.

Riboflavin (B2) works with the other B vitamins. It is important for body growth and the production of red blood cells.

Thiamine (B1) helps the body cells change carbohydrates into energy. It is also essential for heart function and healthy nerve cells.
