good value
These worked for my needs. I had to find calcium without vitamin D and that's hard to find. The price was a good value.

Perfect for Multivitamin Users
I take a multivitamin daily that already has vitamin D in it and don't need extra, which nearly all calcium supplements seem to include now but didn't in the past. So I'm glad I found these calcium-only tablets here.

Calcium without the d
Delivery service so I like this one a lot because I take prescription vitamin d and can't have a calcium with vitamin d. And this one has always been great. Plus it's not expensive and it can be shipped to my house what more can you ask for

Very good
These are larger type vitamins.But I am okay with taking that. The reason I took 1 star away is that I wish it had vitamin D in it. There is a lot of supplements in the container and should last a good long time if taking 2 per day.

Ask your Dr. about your Blood Calcium levels following your next Labs!
Blood Calcium levels differ from the usual report provided during your annual checkup! I did. My blood calcium was below Normal while my Calcium levels taken during a physical were above Normal. I have taken calcium every day for years. However, not all calcium supplements are equal. I was told to switch to Calcium Carbonate. In two wks my blood calcium had increased to an above Normal test result. I feel soooo much better now! Highly recommend this Calcium Carbonate! Easy to swallow, no after taste, and I am a believer!!
