Vitamin B6 is a water-soluble vitamin that exists in three major chemical forms: pyridoxine, pyridoxal, and pyridoxamine.
Vitamin B6 performs a wide variety of functions in the body. In fact, it is needed for more than 100 enzymes involved in protein metabolism and is essential for red blood cell metabolism. The nervous and immune systems need vitamin B6 to function efficiently, and it is also required for the conversion of tryptophan (an amino acid) to niacin (a vitamin). Vitamin B6 helps maintain the health of lymphoid organs (thymus, spleen, and lymph nodes) that make your white blood cells, and helps maintain your blood sugar within a normal range.
Vitamin B6 is found in potatoes, garbanzo beans, chicken breast, oatmeal, trout, sunflower seeds, spinach, ostrich and avocado.
