Vitamins are essential organic compounds that the body needs in small amounts. They cannot be synthesized in adequate levels by the body and must be obtained from the diet. Their main role is to aid enzymes in carrying out various functions within cells.
Vitamins are organic compounds that are essential in very small (trace) amounts for the maintenance of normal metabolism. They generally cannot be synthesized at adequate levels by the body and must be obtained from the diet. Vitamins don't provide energy, but some vitamins help the body use the energy from a nutritious diet. Their most important job is to help enzymes do their jobs in cells.
