Could you post a link to the literature that refers to this "(yes, D2--is now confirmed to be just as good as D3) once a week for 8 weeks, then 50,000 IUs every 2 weeks "forever" after, according to Holick.". Thanks
No posts published so far.
As this article was through a link at Veg Source, I was surprised it didn't address the "D3 issue" - that it is an animal-based vitamin, that it is in virtually all supermarket organic milk and most organic milk products . . . so I was happy to see the first comment (green3r) mention Vitamin D2 which is vegetarian.
This is BIG for me, as I've had melanoma, and basal- AND squamous-cell carcinomas, and two major operations, one on my face. (All is well, skin-grafts all but invisible, but still.)
So can you please put together some information on the level of this article, addressing this for us?
Especially because of the milk issue, it is extremely important to ethically based vegetarians.
Though I only use it for coffee, and research the dairy-farm sources of the milk, etc., milk is the last hold-out before going all vegan. But many people use full dairy regularly, and support on the vitamin D issue could have major effects on change.
Yes, you are right. Vitamin D3 is made usually from lanolin, an animal product.
Until recently, physicians were recommending that D3 was superior, which is problematic for vegetarians.
In my post I mentioned that Dr. Holick had completed recent research that showed that D2 was able to raise the blood levels of vitamin D to a level equivalent to that of D3. There was no difference. It didn't matter--which should be good news for you.
Here's the link to his article:
"Vitamin D2 is as effective as vitamin D3 in maintaining circulating concentrations of 25-hydroxyvitamin D."
J Clin Endocrinol Metab. 2008 Mar;93(3):677-81. Epub 2007 Dec 18.
Here's an explanation of the differences between D2 & D3:
Explain the difference between D2 and D3. Is D3 superior?
D2 was commonly used in the U.S. because it was approved as a pharmaceutical in 1911. But Dr. Bruce Hollis doesn't like to use it. It's unnatural. It comes from yeast. It's functional, but D3 is preferable, and it's very easy to get these days. If you have the option--Hollis says, "Use D3".
So there you have it. If you want to avoid D3, D2 will work just fine!
Thanks to The Healthy Librarian for a very interesting and useful post about current research on Vitamin D.
Regarding comments on dairy, the article mentions a top Vitamin D expert's own regime for getting adequate D, and because the guy isn't vegan he uses non-vegan sources like milk (from which he dervies a very small portion of the Vitamin D he needs, in other words milk isn't much of a source for Vitamin D).
I do not see reporting this expert's habits which include supplementation to be any kind of milk endorsement. One can have soymilk, rice milk or nut milk which can also be fortified w/Vitamin D, just as dairy is.
The takeaway message I get from this article is that Vitamin D is a big deal, most people don't get enough, trying to get enough Vitamin D from any enriched food source (like milk or soymilk) won't do much, and we should pay attention to our Vitamin D levels.
Drs. McDougall, Fuhrman and others also have perspectives on Vitamin D. I think it's important to get all the info you can from a variety of sources so you can make informed decisions.
First thing this article does not belong here.All it is is a endorsement of animal based diet.Don't you find it interesting that all of sudden there are studies everywhere confirming the need for vitamin and now by an expert in very high doses.Isn't it kind of peculiar that you only get it from one source.Ask your self this question.
Who benefits from info like this?
One of the best things anyone can do for their health is eliminate ALL DAIRY from their diet "immediately".I speak from personal experience.
You've made a very excellent comment and made an astute observation. Good job and please continue to expose health advice fraud!
