True.. but only if its processed brands of vitamin A, Like Walmart.. Walgreens, CVS and such.. its all a Monopoly of non working non natural non organic vitamins, and lets not talk about the chemicals these companies put in this pills...
in conclusion it doesn't cause Cancer.. its a Vitamin, but it will if its Taked By Processed Suplementation.. therefore one should Take NATURAL/ORGANIC Vitamin A supplementation, no Side effects, and ofcorse we can't exeed the amount per day.
