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!

Vitamin D

This is hard to write a review on because you can't tell if it's working unless you have blood drawn. It was a fair price for the amount of pills.

Bad smell.

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