Strong odor

Bought these because they are in safflower oil, but they smell terrible, unlike any other vitamin D soft gels. Website pictures do not show the full label where it says 'Product of India'.

I will no longer buy this product -- it is changed

After several years of being extremely pleased with how these vitamins work and their excellent value, I will no longer buy them or recommend anyone anyone else buy them. As of January 2023, it seems these vitamins have a new label but that's not all; they are no longer USP Verified to contain the labeled amount of vitamin per softgel. Having this verification is absolutely necessary for me to purchase vitamins. I will now only buy from a competitor that uses this verification on their warehouse brand or from NatureMade (the first to use it).

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.

Softgels, tiny little footballs until...

Buyer beware. I got a bottle of these today via member's pickup and didn't think to check that the item wasn't damaged. After all, it's a vitamin not something like a dairy product. When I got home and opened the bottle, the little softgels had melted together into one solid lump.

Excellent vitamin D3

Excellent product at a great price. Slowly, we have switched over to Sam's Club vitamins. We use five different ones and they are great. My wife takes this Vitamin D3 and says it works well for her. The same vitamins at a lower cost than the national brands.
