My vitamin level was extremely but with my GI tract disease I cannot breakdown and absorb food nor most supplements and the liquid forms of vitamin D3 made me ill. I have used other products by Natural Factors and decided to try their dry D3. I found I could breakdown the tablets and was able to tolerate without any problem 4 tablets a day. My levels were raised and have been maintained for over two years. I highly recommend this product.

I have used this every winter for 10 years. It reduces my Winter Blues to almost zero. It's absolutely wonderful. I tried doing without it 5 years ago and by Christmas I started taking it again. The best dose for me is 4000 IU with my breakfast. From B.C. Canada
