Excellent calcium supplement. I prefer the calcium citrate vs the calcium carbonate since the citrate doesn't need to be taken with food. Have been taking it for almost 2 years at my doctor's recommendation for the onset of osteoporosis. Probably should have started earlier than at age 65, Found this a better deal on Amazon than at Costco. Will see in the next few months when I return to the doctor's for a bone density test, how effective it has been. Read more

I waited to write this review to see if my calcium levels and bone density improved from the other products I had been using. My Dr. is quite pleased, as am I.

Calcium Citrate (as opposed to calcium carbonate) is the best way to get calcium absorbed by your body. This product delivers, and the price is excellent. I have been taking this supplement for many years and my bones are happy for it. As a senior woman, I know that calcium is so important for my general health and well-being. Read more

I have used 21st Century calcium citrate for several years. When last order was placed, the tablets were describes as caplets. They are the same size, large pills, difficult to swallow pills. This is misleading information for the consumer. Shame on 21st Century! Read more

I can usually handle large pills to swallow but these are terribly big. Even if I break in half it gets stuck in my throat. I have a brand new untouched bottle never opened and 1/8 used from the other that I can't use. I hate discarding them. But I don't know what else to do. Read more

The tablets work wonders for me with lower back issues, and I have used them for some while now with great success. The service this specific seller provides cannot be bettered. Add these together and they have a customer for as long as I have use for the product. Read more

I like ordering 21st century calcium citrate with D in quantity as both my husband and I take 2 tablets a day. It helps keep our bones in good shape for which we are thankful. The 2 containers were well packed. Read more
