Calcium carbonate absorbs poorly, 600mg exceeds single-dose max, and no K2 means calcium might end up in your arteries instead of bones. Research suggests calcium supplements without K2 may increase heart risk. Eat dairy or use calcium citrate + K2 instead.
Calcium carbonate is the cheapest, least absorbed form. 600mg per tablet exceeds the 500mg max single-dose absorption. D3 at 800 IU is fine. Split into two doses if you insist on this product.
