Very easy to swallow

I just purchased this product and am delighted at how small the gel caps are. There is a visual reference on the bottle for the shape and true size of the pill, and it is 100% accurate. The gel caps are soft and go down like a breeze! This is important to me because I have trouble swallowing medium or large medication tablets, and it's pretty hopeless if they are uncoated. I found out that there are two types of vitamin D supplements - D2 and D3. Basically, D2 comes from plants sources and D3 is what's made by your skin. I read information online that claims vitamin D3 supplements are better absorbed by your body than D2 supplements, so I'm giving this product a try since prescription mega doses of vitamin D2 did not work well to raise my blood levels. Please note that my rating is based only on the physical attributes of the gel caps, and not on the effectiveness of the supplement being beneficial to anyone's health.

USP verification missing from delivered product

Web site displays product as USP (United State Pharmacopeia) Verified while the actual delivered product does NOT reflect USP verification. This is a major disappointment; -I will not reorder. D3 vitamins that are verified have some what higher cost. Minus verification, customers have zero insurance what is actually in the gel caps.
