Product analysis
Calcium Magnesium plus Zinc can help fill mineral gaps that matter for bone health and normal body functions. Unknown proportions in the calcium and magnesium mixtures make their absorption quality harder to judge.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality46
Zinc gluconate is a favorable source, while the calcium and magnesium use mixtures of stronger and weaker choices. Their undisclosed proportions leave the quality of those mixtures uncertain.
Ingredient Transparency80
The mineral amounts and source names are listed clearly. The missing proportions in the calcium and magnesium mixtures prevent a precise comparison of their sources.
Value For Money65
Calcium offers favorable value, while zinc is more middle-of-the-range. The magnesium mixture is less compelling for the cost because its source proportions are unknown.
Customer Satisfaction92
Customer feedback is very positive. Many reviews provide a well-established picture of satisfaction.
Product Focus64
The small set of minerals supports several nutritional needs, most clearly bone health and low mineral intake. Benefits for mood, testosterone or stress remain conditional on nutritional status or limited evidence.

Magnesium · 400 mgZinc · 15 mg
Magnesium offers nutritional support when dietary intake is low, with a meaningful contribution depending on the declared amount. Calcium can help fill a dietary gap that would otherwise contribute to bone loss. Larger amounts do not establish greater health benefits once intake is adequate.
How this product is rated for Everyday Health
Ingredient fit82
The formula supplies counted nutrients with differing amounts. Their usefulness is primarily in filling dietary gaps.
Goal fit
The formula concentrates on the counted nutrients, while its links span several health purposes.
Dose adequacy
The amounts provide partial coverage of the saved nutrient references; the comparison is not a measure of absorbed nutrients or clinical benefit.
Pathways80
The strongest saved coverage concerns energy metabolism cofactors. These nutritional roles do not establish broad preventive benefits.
Depth
The strongest saved coverage concerns energy metabolism cofactors, reflecting nutritional roles rather than proven disease prevention.
Breadth
The saved coverage reaches energy metabolism cofactors, bone and mineral metabolism.
Evidence86
Magnesium leads the saved evidence finding through nutritional relevance; this does not establish extra benefit when intake is already adequate.
Evidence strength
Magnesium leads the saved evidence finding through nutritional relevance; this does not establish extra benefit when intake is already adequate.
Studied preparation
The saved preparation check is satisfied for the counted nutrients. No chemical-form or delivery advantage is established.
Formulation logic100
No ingredient conflict was matched in the supplied findings. The saved partner requirements are satisfied.
Partner coverage
The counted nutrients work independently or meet their partner requirements under the saved findings; no additional combination benefit is established.
Conflicts
No ingredient conflict was matched in the supplied findings.
Effective doses
All counted nutrients pass the saved minimum amount threshold; this describes eligibility rather than a proven dose that improves health.

Magnesium · 400 mgCalcium · 1000 mgZinc · 15 mg
Calcium supplies mineral for normal bone formation and can fill a dietary intake gap. Magnesium supports normal bone metabolism when intake is low; routine osteoporosis or fracture prevention is not established.
How this product is rated for Bone Health
Ingredient fit89
The supplied nutrients receive differing amount-based contributions for bone support, with any broader-purpose ingredients reducing focus.
Goal fit
The counted ingredients connect to the goal; links to other goals also influence how focused the formula is.
Dose adequacy
The counted ingredient amounts receive full recognition in the saved findings; this does not establish a universal effective dose.
Pathways80
The strongest connection is bone mineral supply. The wider coverage is concentrated in bone mineral supply, collagen matrix formation.
Depth
Bone mineral supply is the strongest represented route in the saved findings.
Breadth
The broader coverage is concentrated in bone mineral supply, collagen matrix formation; other routes do not reach the same level.
Evidence100
Calcium carries the strongest evidence among the counted ingredients. The counted preparations are recognized as studied.
Evidence strength
Calcium provides the strongest evidence among the counted ingredients; this does not predict the size of an individual benefit.
Studied preparation
The saved findings recognize the counted preparations as studied; this does not guarantee equivalent effects across regimens or populations.
Formulation logic95
A missing partner limits one contribution. No listed conflict was identified, while amount eligibility follows the separate amount findings.
Partner coverage
Calcium lacks its recognized vitamin D partner, reducing its supported formulation role.
Conflicts
No listed conflict was identified at the supplied amounts.
Effective doses
All counted ingredients meet the saved amount criterion; this does not make every included amount a proven effective dose.

Magnesium · 400 mgZinc · 15 mg
Zinc supplies a nutrient needed for normal immune function when intake is low. Its strongest connection is to immune regulation, without establishing infection prevention or transferring acute zinc-lozenge findings to this serving. Magnesium also received a saved contribution, but immune-cell and inflammatory-marker observations do not establish a routine supplementation benefit against infections.
