Vitamins are organic micronutrients found in small quantities in foods. As constituents of the body's enzyme systems, vitamins play a key role in metabolic processes and are vital in maintaining optimal health.

Vitamins can be divided into two groups: the water-soluble vitamins e.g. B- vitamins; vitamin C, and fat-soluble vitamins e.g. vitamins A, D and E. Today’s busy and demanding lifestyles mean that it may not always be easy to follow a healthy balanced diet.

Supplementation is a useful way of ensuring a dietary intake of these essential nutrients.
