| Re: Vitamins the truth behind RDA's
Given the poverty of condensed vitamin info out there, this is a real breath of fresh air in it's depth and clarity.
That said, I want some confirmation about the toxicity levels of Vitamin A, most sources I've seen place it around 3200 - which is a big disparity. What studies have demonstrated normal body function at 8000??
Agree about RDA, it's a pathetically unrealistic yardstick that started many years before the advent of bodybuilding, before we had so much pollution and refinements in our food.
Most people think of RDA as "A minimum amount of nutrients I need to feel great every day!" whereas in fact it has only two purposes, both of which are utter copouts...
1) So manufacturers can get away with making food appear healthier than it is;
2) To avoid the risk of advocating toxic levels of vits.
Ok that' all, any proof on Vit A toxicity levels appreciated.
