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.

Bad smell.

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

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.
