Cal-Mag Citrate 2:1 Ratio supplies calcium, magnesium and vitamin D that can help fill dietary gaps relevant to bone health. The mineral and vitamin D contributions offer weak value at the serving cost.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality38

Calcium citrate has a favorable form comparison, while vitamin D uses the less favorably compared D2 form. Magnesium combines citrate and oxide in undisclosed proportions, limiting confidence in the mix.

Ingredient Transparency73

Amounts and the main nutrient forms are listed. Some component details, including the mineral mix proportions, remain undisclosed.

Value For Money22

Calcium, magnesium and vitamin D compare poorly for value at the serving cost. The carbohydrate contribution cannot be judged reliably for price.

Customer Satisfaction83

Customer feedback is very positive. The review count provides a useful range of buyer opinions.

Product Focus71

The short ingredient list centers on minerals relevant to nutritional needs. Its broader range of stated health uses has less consistent support.
