Ingredient:

Vitamin B6 (from baker’s yeast, rice bran, rice fiber and organic fruit and vegetable powders)

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.
  Baker’s yeast, Saccharomyces cerevisiae, also known as brewer’s yeast, is a yeast often used for baking or brewing. It is an excellent source of the essential B vitamins, including folic acid, niacin, biotin, pantothenic acid, riboflavin, thiamin and vitamin B6 2.
  Rice bran is made from the bran layer, underneath the hull layer, of rice, Oryza sativa. Rice bran is high in dietary fiber, and is an excellent source of protein, vitamin E, thiamin, niacin, vitamin B6, pantothenic acid and a number of minerals, such as iron and magnesium. It is also a good source of folate and riboflavin 3. Rice bran also contains beta-sitosterol and other phytosterols, along with the essential omega-3 fatty acid alpha-linolenic acid (ALA) 4.
  Rice fiber is the soluble and insoluble fiber obtained from the bran layer of the rice kernel.
  Organic fruit and vegetable powders are obtained from organically grown fruits and vegetables, including strawberry, raspberry, blueberry, cherry, pomegranate, cranberry, broccoli, tomato, carrot, spinach and kale.
