Guest guest Posted January 19, 2008 Report Share Posted January 19, 2008 Hi and Carol, Could you point out the so-called blocking that Vitamin A and D have? Assuming you are inferring A blocks D's absorption. There is no evidence of an association between beta-carotene intake, especially from fruits and vegetables, and increased risk of osteoporosis. Current evidence points to a possible association with vitamin A as retinol only and that is if retinol is taken in doses three times the daily recommendation. That would be 3,000 mcg (10,000 IU) or more per day as retinol equivalent. Sorry, I just don't buy it or maybe I don't get what you mean. At least one scientific study would be appreciated.

Guest guest Posted January 20, 2008 Report Share Posted January 20, 2008 i have no idea, as you can see from my previous post i am still questioning why my Fish oil caps -for Omega 3- don't mention their Vit A content at all (or their vit D content) and wondering why my new Vit D supplement (made from fish), mentions that it *Intrinsically contains a rather large amount of Vit A. > > > > > > But the cod liver oil has a " blocking " effect beCAUSE the A is > > combined with the D.

Guest guest Posted January 20, 2008 Report Share Posted January 20, 2008 I've been studying Vit D for many months now. I've also been studying the importance of Vit A. and have come to the conclusion that taking high doses of one can create an imbalance of the other with subsequent health consequences. Here is an article that kind of brings it all together and summarized what I've been finding to be true, both in my research and also in my personal experience, having had toxicity symptoms with relatively low doses of Vit D, far lower than everyone seems to be advocating. I've run into other people experiencing this same problem. It dispels some myths about both of the vitamins. http://www.westonaprice.org/basicnutrition/vitamina-osteo.html#appendix2 > > Hi and Carol, > > Could you point out the so-called blocking that Vitamin A and D > have?

Guest guest Posted January 21, 2008 Report Share Posted January 21, 2008 Great article . Guess it means that we don't really know what's going on in there, except on a person to person basis. That is, if you can a doctor to run any tests to find out. Six of one and half a dozen of the other, huh. That's the way I'm interpreting this article. I simply read somewhere, within the last few wks or so, that these two cancel each other our, IF they're taken together, and I must not have bookmarked it cause I can't find it!
