Calcium citrate form is the smart choice, absorbing without stomach acid. 630mg is a meaningful dose (63% of optimal). D3 at 500 IU is only 13% of optimal, which is too low. Magnesium hydroxide at 50mg is negligible. Boron at 250mcg is far below the 3mg minimum effective. Good calcium form, decent dose, but the supporting nutrients are underwhelming.
The set is generated, never written by the brand.
Citracal Maximum Plus D3: the formulation holds up. Lead: Calcium at 630 mg. Calcium citrate form is the smart choice, absorbing without stomach acid. Clinical dose on the primary, and the panel holds together.
The smarter calcium at Walmart. Calcium citrate absorbs without stomach acid (carbonate can't). Critical difference for anyone over 50. Still no K2 to direct calcium to bones. Add K2 separately. Split the dose since 630mg exceeds single-dose absorption max.

This read comes from the product's own supplement facts panel. Every dose was cross-referenced with published clinical trials to see whether it matches what the studies actually used.
