I have a book on vitamins that came out in 1988 and it already lists bone and joint issues among the side effects of taking vitamin A. Title of the book is “Complete guide to vitamins, minerals & supplements” and it is by H. Winter Griffith. Another side effect it mentions is premature closure of the end parts of bones where growth occurs from birth to adolescence. The SCIENCE of VITAMINS. Minerals, and other necessary supplements is an EXACTING Science, Anyone who is interested in his or her health, should make an effort to ecome thoroughly acquainted with his critical subject matter. Yout health and life span may depend on it!Everything has side-effects, including vitamins.
The conventional wisdom is to not supplement much more that youd expect from a well balanced diet. years ago I was working at a hospital wellness center as a trainer. We had an RD who, like most RD’s was dumb as a rock (she didn’t like me and the feeling was mutual). Anyhow, she had a rather large food display showing that wonderful example of USDA propaganda, the US Food Pyramid. I mean it was the honking big plastic thing with plastic food examples. So I’m sitting with my supervisor watching this chick try to load it onto a dolly for transportation. It flipped over and fell off. I look at him and said “Gee, guess her diet wasn’t balanced.” That still cracks me up.
