NOW Foods Supplements, Cal-Mag DK with Vitamin D-3 and Vitamin K-2, Supports Bone Health*, 180 Capsules

The labeled daily routine provides 532 mg calcium, 266 mg magnesium, 16.6 mcg vitamin D3, and 60 mcg vitamin K2, which is a reasonable maintenance supplemental amount for the stated role.

Calcium citrate is a well-tolerated relevant form, but magnesium oxide has comparatively limited absorption and can be less well tolerated, creating a supported limitation in this mixed formula.

The labeled routine is two capsules twice daily, and the container provides 180 capsules.

The quantified nutrient amounts and their listed compound sources are internally consistent, and the repeated vitamin K2 line is not an incompatible amount.

The formula covers the stated mineral and vitamin roles in reasonable proportions without an established compatibility problem, while the magnesium form limitation is assessed separately.

The label shows ordinary excipients without a documented contaminant or problematic additive, but no product-specific purity testing is supplied.

Vitamin D3 and K2 have relevant complementary roles in calcium metabolism and bone health at declared amounts, although their added clinical benefit varies by individual status.
