I think these will do just fine. They are not too dissimilar to what I already take, with the exception of the added D3. You just need to know what dose of D3 your body should intake. At one point I was low, then went the opposite, so now I am to take about 2000 IU daily, instead of 5000+. this has 1600 IU, which leaves the door open for a little more to sneak in from other supplements. The amount of Calcium in this, at 1200, is just right for me right now as well. The good thing is that even though these are 2 pill doses, the size of these caplets are not too big, relative to some other bigger horsey sized calcium pills. THey are easier to swallow. Only time will tell if these work. I'll see my next blood test.

This Calcium 1200 mg Plus Vitamin D3, Bone Health & Immune Support - Nature's Calcium Supplement with High Potency Vitamin D for Extra Strength Carbonate Absorption Dietary Supplement - 60 Tablets works great. Would recommend.

Been taking this for about six weeks. Energy is more consistent and I feel less sluggish in the afternoons. Happy with the purchase.

Works well. Deducting a star because the bottle is hard to open with one hand, but the product itself is solid.

Good quality supplement. About three weeks in and noticing a difference, mostly in energy levels.

Third-party tested, clean label. That's what I look for first. Actually works too, which is a bonus.
