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!!

Economical Size and Dosage
Great value for the money. These are a bit large, but their shape and coating makes them easy to swallow. I am a repeat buyer so I hope they never stop carrying these.
