Vitamins Functions and Food Sources

The Functions and Food Sources of the Major Vitamins

Vitamins are chemicals which we need in relatively small amounts, to grow and remain healthy. Some are needed in only a few thousandths or even millionths of a gram each day.

Their role is to take part in the chemical reactions of metabolism. The lack of a vitamin causes the reaction in which it takes part to slow down. Since most metabolic reactions are part of long sequences of events, an alteration in the rate of any one of them can have widespread effects on the body.
