I understand the article but, being a strict vegan who will probably never take D3, I would rather hear about the similarities in vitamin D2 and D3 rather than the differences. From what it sounds like, other than cost, convenience and frequency of use — all minor things for a vegan — I didn’t see a real difference relating to its effects on the body.

Can you please answer the question as to whether D2 and D3 have the same benefits to the body? (In whatever equivalent dose/frequency is necessary.)

Trish, D2 is equally effective as D3. However, D2 is vegan and D3 is not. There is no vegan source of D3 as it comes from lanolin or fish.

I have a friend who is on Drisdol and is an ethical vegetarian. My question is how is VD3 obtained? If this means death for the animal is there a vegan source of V3?

Have just started reading the book, which so far is excellent. My current vitamin d3 intake has been 2000iu which seems to have improved my blood sugar levels .I reversed my type 2 diabetes three years ago after fourteen years of injecting insulin and have been completely free from any diabetic medication. My goal is to explore all possibilities of reducing arterial plaque and hoping this book is the answer.

My doctor recently tested my Vit. D levels and found they were low. She prescribed D(2) at 50,000 IU weekly for 4 months. After hearing an excellent interview with you on our local radio station, I just purchased your book. I ordered Vit. D(3) from Carlson Labs. I have started the D(3) supplementation. According to your chart I am taking 5,000 IU daily.
My question is this…is it okay to NOT take the prescription D(2)? Or should I take it short-term to boost levels and then continue on the D(3)?

Thank you immensely.
