Good replacement for OsCal
These are a good replacement for the now-discontinued OsCal calcium supplements. I use them twice daily, and after several months my labs still are great.

Great calcium
I purchased these for every day use. I canceled my Costco card. And therefore this was the next best thing. I am happy with them.

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.
