Vitamin D

How does one review a vitamin? It was suggested I take it, so I do. What it does? Besides help make bones stronger and help immune system I have no idea!

Vit D

Exactly the amount my doctor requested me to take. Small and easy to get down.

6 months expiration

Purchased the vitamins, sent to a friend. Just found out the expiration on the tablet is within 6 months. How can complain about it or return for a longer expiration it was already sent outside country to a friend who needs it. And they are 3 bottles with expiration date within 6 months and its 400 capsules. You could not even consume everything and it already expires.

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.

Picture On Site is Inaccurate

The photo on the Sam's Club site clearly shows a USP certified label. Yet, when I received the bottle there is no USP certification on the bottle's label. Had I known they weren't actually USP certified, I would have never bought them.

Bad smell.

I will not be buying this brand again because of the smell. The previous brand Sam’s was selling was good.

Not as advertised

I bought these because they were USP Certified (in the product listing). What came to my house was not USP Certified.
