Product analysis
Cal-Mag Citrate 1:1 ratio helps fill calcium and magnesium gaps that matter for normal bone maintenance. Unknown mineral-source proportions make absorption harder to predict.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality37
The mineral blends include forms with different absorption characteristics. Undisclosed proportions, especially for magnesium oxide, make the amount the body can use less clear.
Ingredient Transparency70
All listed amounts and the mineral forms are stated, making the basic formula easier to check. Mineral-source proportions and the protein form remain undisclosed.
Value For Money26
The serving price is high as a source of calcium, and the magnesium blend offers limited value. Value for the listed protein remains uncertain.
Customer Satisfaction81
Customer ratings are favorable. More than a thousand responses give a broad view of satisfaction.
Product Focus78
The main use is filling calcium and magnesium gaps for normal bone and energy functions. The 1000 mg magnesium serving exceeds the comparison range, while calcium is generally absorbed more efficiently in amounts of 500 mg or less.
