NaturesPlus Calcium/Magnesium/Vitamin D3 with Vitamin K2 - 60 Chewable Tablets - Supports Bone & Immune Health - Vanilla Flavor - Gluten Free - Up to 30 Servings

At two tablets, the directions specify 600 mg calcium and the 600 mg magnesium panel amount likely corresponds to four tablets, but the serving basis and which vitamin D3 amount applies are unresolved, leaving overall complex adequacy uncertain.

The calcium and magnesium forms are not identified, leaving relevant absorption and tolerability properties of this complex unresolved; the identified D3 form does not resolve those uncertainties.

The directions allow two tablets daily for 600 mg calcium, so I assess that smallest listed routine; the 60-tablet package supports 30 such routines.

The serving size is absent and vitamin D3 appears twice at different amounts without a stated basis, so the applicable amount cannot be reconciled from the supplied label text.

The listed calcium, magnesium, and vitamin D3 have a plausible complementary role, with no specific compatibility defect established at the assessed routine.

No product-specific purity controls or defects are established; the label lists sugar and other ordinary formulation ingredients.

The separately declared 100 mcg of K2 is a meaningful supporting ingredient for the bone-support purpose, although its added benefit in this complex is uncertain.
