RNA synthesis and cellular division rely greatly on the availability of this vitamin.

Vitamin A helps in the conversion and storage of glycogen which is utilised at the time of intense workouts. Vigorous exercise sessions can deplete vitamin A storage from the body, which in turn can effect adversely on the protein metabolism.
