Product analysis
Calcium Magnesium Zinc + D3 helps fill dietary gaps that matter for bone maintenance and normal muscle function. Magnesium and zinc are supplied as oxide forms, which are less favorable choices for absorption.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality30
The mineral forms offer a mixed picture, with magnesium oxide and zinc oxide less favorable for absorption. Calcium carbonate is a more moderate choice, while vitamin D form quality cannot be judged fully.
Ingredient Transparency100
The amounts and forms of all four nutrients are clearly stated. That makes it straightforward to compare the formula with your dietary needs and other supplements.
Value For Money61
The low cost per serving supports good value for calcium and zinc. The magnesium oxide form offers less value when absorption quality is taken into account.
Customer Satisfaction92
Customer ratings are strongly positive across a very large number of ratings. The broad feedback base gives a more dependable picture of satisfaction than a small sample.
Product Focus66
Bone nutrition is the clearest shared purpose of these nutrients, particularly when dietary intake is low. The formula also covers many broader aims, but extra benefits with adequate nutrition are uncertain.
