Supplement comparison results

Primary ingredients How we evaluate

We verify that the calcium to magnesium ratio (2:1) is appropriate and examine daily recommended amount (mg) fulfillment. We also examine calcium processing methods (calcination-free, coral calcium, etc.) and raw material quality, whether vitamin D content is sufficient for improving absorption.

Price How we evaluate

We calculate per-tablet unit price to compare actual ingredient cost-effectiveness. We evaluate practical cost-effectiveness reflecting calcium/magnesium content, vitamin D combination effects, and absorption efficiency rather than just retail price.

Brand How we evaluate

We comprehensively review GMP, NSF, and ISO certification status, whether raw material sources and manufacturers are disclosed, and health functional food certification. We particularly highly evaluate brands where sources of calcium, magnesium, and vitamin D are all clear.

Quality How we evaluate

We multi-dimensionally evaluate formulation stability and absorption efficiency enhancement (dark packaging, individual packaging), dosing convenience, and capsule size/form (liquid, tablet, etc.). We also include unnecessary additive (cellulose, magnesium stearate) management in quality items.

Additional ingredients How we evaluate

We verify inclusion of bone metabolism and absorption-supporting components (vitamin K, zinc, manganese, polygamma-glutamic acid, etc.). We carefully evaluate ingredient overlap risks, allergen potential, and long-term consumption safety.
