Product analysis
Calcium & Magnesium Citrate Powder with Vitamin D3 can help fill mineral gaps and support normal bone health. It offers good value for the calcium and magnesium supplied.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality65
Calcium and magnesium use citrate forms, favorable choices for absorption. Vitamin D3 is named, but its form quality cannot be confirmed from the available details.
Ingredient Transparency100
All listed amounts and forms are identified. That makes comparison with other mineral servings straightforward.
Value For Money74
Calcium and magnesium offer good value at the serving price. Vitamin D lacks a reliable separate value comparison.
Customer Satisfaction84
Customer ratings are generally positive. A large number of ratings gives a broader picture of customer satisfaction.
Product Focus70
Mineral nutrition and bone support are the clearest uses of the combination. Wider benefits for stress, energy and cardiovascular function depend on nutritional status and remain less predictable.

Magnesium · 400 mgCalcium · 400 mgVitamin D · 5 mcg
Calcium supplies bone mineral and magnesium supports normal bone metabolism, particularly when dietary intake is low. The 400 mg calcium serving offers partial mineral support, while magnesium is fully recognized by amount. Vitamin D is present at 5 mcg per serving but falls below the saved inclusion threshold, so it does not satisfy calcium's partner requirement there. Citrate forms do not establish superior bone outcomes or fracture prevention.
How this product is rated for Bone Health
Ingredient fit79
Calcium and magnesium supply mineral support, with calcium contributing a partial amount.
Goal fit
The recognized ingredients focus on bone minerals, with broader goal links.
Dose adequacy
Magnesium is fully recognized; calcium receives partial amount support and vitamin D falls below the threshold.
Pathways60
Mineral supply dominates, with a smaller calcium-regulation connection.
Depth
Calcium and magnesium strongly represent bone mineral supply.
Breadth
Only mineral supply reaches substantial coverage.
Evidence100
Calcium provides the strongest assigned evidence; citrate does not establish superior bone outcomes.
Evidence strength
Calcium supplies the strongest reviewed support present here.
Studied preparation
Both recognized citrate preparations are accepted in the saved findings.
Formulation logic92
Calcium's vitamin D partner is too small to count; no conflict is matched.
Partner coverage
Vitamin D is present but below the amount needed for calcium's partner coverage in the saved findings.
Conflicts
No matched ingredient conflict is present.
Effective doses
Calcium and magnesium meet the threshold; vitamin D does not.
Impact
Highest effect
Vitamin D · 5 mcgMagnesium · 400 mg
Magnesium and calcium provide minerals involved in normal bone and mineral processes, with magnesium also participating in energy metabolism. They can help fill dietary gaps. Vitamin D is present at 5 mcg per serving, but its contribution was not retained in the saved findings. Citrate forms do not establish superior effects, and normal nutrient functions do not imply extra benefit when intake is adequate.
How this product is rated for Everyday Health
Ingredient fit86
Magnesium and Calcium provide the main relevant nutrients. Their amounts vary in their contribution against the supplied references.
Goal fit
Magnesium and Calcium account for the main nutritional connection to general health.
Dose adequacy
Amounts make uneven contributions against the supplied references; smaller or unresolved amounts limit what can be attributed to the serving.
Pathways80
The retained contributions concern energy metabolism, bone and mineral processes. These are nutrient roles, rather than proof of broader health improvement.
Depth
The strongest supplied finding concerns energy metabolism; this describes nutrient-related support, not a measured health improvement.
Breadth
The retained contributions span energy metabolism, bone and mineral processes.
Evidence86
Magnesium leads the retained evidence finding. The practical general-health interpretation remains nutritional support when intake falls short.
Evidence strength
Magnesium provides the strongest retained evidence finding; its nutritional role does not establish additional benefit above adequate intake.
Studied preparation
The retained preparations match those accepted in the supplied comparison, without establishing that one form is superior.
Formulation logic100
The retained ingredients have no unmet partner requirement or configured conflict. Their amounts meet the supplied minimum comparison criterion.
Partner coverage
The retained ingredients can contribute alone or have their required partner; this does not establish extra benefit from combining them.
Conflicts
No configured ingredient conflict was identified in the supplied findings; this is not a comprehensive safety assessment.
Effective doses
All retained ingredients meet the supplied minimum amount criterion; that criterion is not a proven effective dose.
Impact
High effect
Vitamin D · 5 mcgMagnesium · 400 mg
Magnesium helps address fatigue and weakness when magnesium intake is deficient. Meeting nutritional needs does not establish an extra energy boost in someone whose intake is adequate. The declared serving reaches the saved amount comparison, which is not a fatigue-treatment dose or evidence that more is better. Vitamin D is below the saved inclusion comparison.
How this product is rated for Energy
Ingredient fit77
Magnesium anchors this product’s saved energy connection. The declared amounts reach the saved comparison levels; this does not make them validated fatigue-treatment doses.
Goal fit
Magnesium contributes to the energy findings within a formula that also serves other purposes.
Dose adequacy
The declared amounts reach the saved comparison levels; this does not make them validated fatigue-treatment doses.
Pathways0
No direct alertness, exercise-energy or stress-fatigue pathway contribution was recorded. Deficiency-related fatigue can still be nutritionally relevant.
Depth
No direct alertness, exercise-energy or stress-fatigue pathway contribution was recorded.
Breadth
No direct energy area reaches the saved coverage threshold; nutritional relevance and routine energy enhancement remain different questions.
Evidence88
Magnesium is relevant to deficiency-related fatigue, without establishing extra energy at adequate intake.
Evidence strength
Magnesium is relevant to deficiency-related fatigue, without establishing extra energy at adequate intake.
Studied preparation
The preparation qualifies in the saved findings, although population and treatment limits still govern how its effects can be described.
Formulation logic100
No missing partner or specified conflict was identified. The included amounts meet the saved minimum comparisons, without establishing a routine energy benefit.
Partner coverage
The included ingredients do not require a missing partner for the roles described.
Conflicts
No specified ingredient conflict was identified in the supplied findings.
Effective doses
The included ingredients meet the saved minimum amount comparisons; these are not proven fatigue-treatment thresholds.

Magnesium · 400 mgVitamin D · 5 mcg
Magnesium contributes to the balance of minerals and blood-vessel tone. Its blood-pressure effects in the supplied evidence are small and inconsistent, so a meaningful amount does not establish prevention of heart attacks or strokes.

Vitamin D · 5 mcgMagnesium · 400 mg
Magnesium citrate supplies 400 mg of magnesium per serving and may help retain water in the bowel, supporting softer stools and regularity. Its digestive contribution is focused on stool regulation; the supplied evidence does not imply broader gut benefits. Vitamin D at 5 mcg adds little at the supplied comparison amounts.
