Vitamin B6
Definition
Vitamin B6 is a water-soluble vitamin. Water-soluble vitamins dissolve in water. The body cannot store them. Leftover amounts of the vitamin leave the body through the urine. That means you need a continuous supply of such vitamins in your diet.
Alternative Names
Pyridoxine
Function
Vitamin B6 helps the immune system produce antibodies. Antibodies are needed to fight many diseases. Vitamin B6 helps maintain normal nerve function and form red blood cells. The body uses it to help break down proteins. The more protein you eat, the more vitamin B6 you need.
Food Sources
Vitamin B6 is found in beans, nuts, legumes, eggs, meats, fish, whole grains, and fortified breads and cereals.
Side Effects
Large doses of vitamin B6 can cause neurological disorders and numbness. Deficiency of this vitamin can cause mouth and tongue sores, irritability, confusion, and depression. (Vitamin B6 deficiency is not common in the United States.)
Recommendations
Specific recommendations for each vitamin depend on age, gender, and other factors (such as pregnancy). In general, a healthy diet typically supplies enough vitamin B6.
