Product analysis
Cal/Mag/Vit D3 with Vitamin K2 may help cover nutritional gaps that affect normal bone and muscle function.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality56
Magnesium uses a reasonably favourable form, while calcium and vitamin K have more moderate form profiles. The named vitamin D preparation does not by itself establish a further quality advantage.
Ingredient Transparency100
All four nutrient amounts and forms are disclosed. That makes the combination straightforward to compare with other mineral supplements.
Value For Money47
Calcium, magnesium and vitamin K offer middling value at the full serving cost. The separate value of vitamin D remains uncertain.
Customer Satisfaction84
Customer feedback is positive. Thousands of ratings provide a broad base for judging satisfaction.
Product Focus66
The formula centres on normal bone and mineral nutrition, chiefly when intake is low. The large calcium and magnesium amounts do not establish extra benefit, and the MK-4 form cannot be assumed to match MK-7 bone findings.
