    What I don’t get is if people can’t convert beta carotene to retinol then why is no one in the United States or any developed country Vitamin A deficient? Vitamin A deficiencies are only found in third world countries

    Hi Rick! Vitamin A deficiencies are found in the United States! Just like many other nutritional deficiencies including vitamin D, B12 and magnesium. But sadly, correcting the deficiency would mean healthier people, and a healthy person does not need pharmaceuticals. This is proven by many diseases that are reversed simply by nutrition therapy.

    I’m confused about the form of vitamin A used in the studies you cited. It must be synthetic retinol to get that high of a dose?
