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!!

Calcium without any added vitamins
I have a calcium deficiency so my doctor recommended I take a supplement. I have been on the supplement for a while now and have had no problems with the tablets. I am on my 2nd bottle of these. I don't have any stomach upset or burning, even if I take on an empty stomach. The amount I take seems to be keeping my levels where the doc wants them, so my last appt I was told to keep taking as I had been. They are rather large tablets, so if you have trouble taking tablets you may want to break it in two. I don't notice any odd taste or flavor with these. I tend to take my meds together at the appointed times so it would be hard to pinpoint one particular pill's flavor. This is a much better value then purchasing in a pharmacy or store. Plus it's difficult to find a calcium supplement that doesn't have an added amount of vitamin D, or mixed with something else. And getting it shipped to your door is very convenient, on top of the money you save over brick and mortar stores. Hope this helps! Be well

Review from a pregnant woman
I’m pregnant and started taking this supplement in my first month of pregnancy. I know how important calcium is for a baby’s development, and I also know that I don’t get the recommended daily amount from my regular diet, so supplementing felt necessary for me. This was especially important because I have patellar chondromalacia, and I understand that not getting enough calcium during pregnancy can lead to bone issues later in life, both for the mother and for the child. I wanted something reliable and easy to take, and this supplement has been a great choice so far. The tablets are easy to swallow and have a score line in the middle, which makes it convenient to split them. I personally take half in the morning and half at night. I’m very satisfied with this purchase and would definitely recommend it, especially for pregnant women who want to make sure they’re meeting their calcium needs.

Not a replacement for exercise
I've tried it but nothing will replace proper diet and exercises like intense double jumps
