Good quality supplements
Good supplements. Have been taking them for a while. Only once, a bottle came already opened. They gave me a refund and told me to keep the bottle. But I was not going to use those pills. So I had a bottle of unusable pills to get rid of. Still, it was good customer service, which I appreciate.

Great Price!
Per doctorโs recommendation I take calcium with D3 everyday and I found this brand on Amazon. This brand is a great value as it comes in a two pack. I take them every night about an hour before going to bed. I read somewhere years ago that calcium is a natural relaxant so Iโve always taken my calcium supplements before bedtime.

Healthy Bones
I like the bright green color of each pill. You will not easily forget to take it because the color jumps right out at you. The pills are not large and not difficult to swallow. The quantity is awesome for the price. Compares in price and quality to most Top Named Brands. My doctor recommended and approves of this brand. Availability thru Amazon was fast and easy.
