For maximum benefits to skin, hair and nails at development and growth stages we need to ensure optimum nutrition. The health of hair, skin and nail tissue is dependent on good levels of connective-tissue supporting nutrients. 

Key micronutrients which are recognised as contributing to the maintenance of normal hair and skin are vitamin C, biotin, zinc and selenium. Vitamin C contributes to normal collagen formation for the normal function of skin.

The human body contains a relatively large amount of sulphur and it is naturally found at high levels in hair, skin and nails. Sulphur is a component of keratin, the main protein of hair and nails. It is also found in collagen and elastin which are proteins found in connective tissue in skin, joints, muscles, bone and blood vessels. Many people do not eat enough raw, sulphur-containing foods on a daily basis.
