Vitamin B2, or riboflavin, is found in dairy products and green vegetables, but is widely distributed throughout most natural foodstuffs.
A lack of riboflavin affects the skin and mucous membranes.
Nicotinamide, or Vitamin B7, is also widely distributed in most foodstuffs.
Vitamin B6, or pyridoxine, is required for the proper functioning of nervous and skin tissue.
B6 has recently been used in relieving premenstrual tension (PMT).
Most of the B-group vitamins form part of the molecules of enzymes in the body, those chemical substances which are necessary for the build-up and break-down of all the body tissues.
Vitamin B12, or cyancobalamin, is formed in the body by the action of a chemical in the stomach acting on another chemical taken in with the food.
