James asks:

With all the new info regarding Vitamin D3, why do you use D2 or the synthetic version in your Green Formula that I take? Thanks

The Vitamin Professor Responds:

We use the D2 form in our ALL ONE Green Phyto Base because it is the only certified vegan form of vitamin D.

ALL vitamin D is synthesized.

D3 from lambs wool, or fish oil, which is not suitable for a vegan diet.

As far as your body is concerned the two different forms of Vitamin D are identical.

While Vitamin D3 is all getting lots of press right now ponder this quote from The Science and Practice of Pharmacy

“Both Vitamin D2 and D3 are precursors (pro-vitamins) and are converted to THE SAME active metabolites, which are responsible for the absorption of calcium.” – Kemington; The Science and Practice of Pharmacy, 19th Edition, 1995 pg. 1111 (emphasis added)

In a few months we will be using vitamin D3 in our ALL ONE Active Senior and ALL ONE Original formulas as vegetarians do not object to a lambs wool source.

Hope this addresses your question.
