Vitamin B6

Vitamin B6, or pyridoxine, is a water-soluble vitamin that functions as a coenzyme in the metabolism of amino acids and the release of glucose from glycogen 1. Major sources of vitamin B6 include fortified, ready-to-eat cereals; mixed foods (including sandwiches) with meat, fish or poultry as the main ingredient; white potatoes and other starchy vegetables; and non-citrus fruits. Vitamin B6 is frequently used in combination with other B vitamins in vitamin B complex formulations.
  Vitamin B6 is generally considered safe in adults and children when used appropriately at recommended doses. The U.S. Food and Drug Administration (FDA) has established a Reference Daily Intake (RDI) of 2.0 mg vitamin B6 for adults and children 4 or more years of age (21CFR101.9). RDIs are a set of dietary references for essential vitamins and minerals that are considered amounts sufficient to meet the daily requirements of healthy individuals. RDIs serve as the basis for calculating the percent daily value (%DV) amounts found on dietary supplement and food labels.
