				 There is increased evidence to show that dietary supplementation of vitamins contributes to cancer prevention and also therapy. This paper explains the anticancer activity of few vitamins and the necessity of preparing their analogs to enhance their bioavailability. While the vitamin supplementation is needed in various health disorders, over supplementation of the same may not be effective due to failure to reach over maximal concentrations in the body. Vitamin mediated anticancer activities include cell cycle progression inhibition, targeting cell survival, inducing autophagy or apoptosis, inhibiting hypoxia, eradication of oxygen free radicals and immune modulation. As the in vitro data seems sufficient to support vitamin biological effects, advanced research is needed to support their in vivo activity and long-term treatment.
