Vitamin A

Vitamin A is a vitamin which is needed by the retina of the eye in the form of a specific metabolite, the light-absorbing molecule retinal.This molecule is absolutely necessary for both scotopic and color vision. Vitamin A also functions in a very different role, as an irreversibly oxidized form retinoic acid, which is an important hormone-like growth factor for epithelial and other cells.

Vitamin A plays a role in a variety of functions throughout the body, such as:
    Vision
    Gene transcription
    Immune function
    Embryonic development and reproduction
    Bone metabolism
    Haematopoiesis
    Skin and cellular health
    Antioxidant activity
