Product analysis
Calcium Magnesium Plus Zinc can help fill mineral gaps that matter for bone health. Its magnesium mix includes a less readily absorbed form, with no indication of how much each form contributes.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality48
Zinc uses a favorable form, while the magnesium mixture includes a less readily absorbed source. Unstated mineral proportions make it harder to judge the absorption potential of the full combination.
Ingredient Transparency71
All ingredient amounts and most forms are disclosed, making the main minerals easy to identify. The proportions within the calcium, magnesium and boron mixtures are missing, so each source contribution is unclear.
Value For Money60
Calcium and copper compare favorably on serving cost, with zinc offering reasonable value. The magnesium mixture is less compelling, and value for horsetail and boron remains uncertain.
Customer Satisfaction87
Customer feedback is strongly positive across many reviews. The review volume provides a broad picture of satisfaction with the supplement.
Product Focus53
The clearest role is filling mineral gaps that affect normal bone and body functions. A much wider set of intended uses stretches beyond the most dependable nutritional benefits.
