Product analysis

62 out of 100

Magnesium Caps 500 mg may help fill a magnesium gap relevant to normal bone, nerve and energy functions. Its blend includes poorly absorbed oxide, and the proportions of the different forms are not stated.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality36

The magnesium forms vary in absorption potential, with oxide less favorable than the other named forms. Their proportions are unknown, so the blend does not reveal how much each form contributes.

Ingredient Transparency80

The magnesium amount and all named forms are disclosed. The proportions of the forms are unstated, limiting comparison with a single-form option.

Value For Money52

The magnesium blend offers middling value once its forms are considered. Unknown proportions limit any precise claim about the contribution of the more favorable forms.

Customer Satisfaction94

Customer ratings are generally positive. A large number of ratings gives a broader picture of customer satisfaction.

Product Focus74

The single mineral can support several normal functions when intake is low. A larger serving does not establish greater benefit or suitability, and stress or cardiovascular effects remain conditional.

Magnesium · 500 mg

Magnesium at 500 mg per serving has a potential connection to bowel regularity through drawing water into the bowel. The supplied constipation evidence is strongest for a specific magnesium oxide preparation, so the amount alone gives limited guidance on symptom benefit.

How this product is rated for Gut Health

Ingredient fit92

The saved ingredient and amount findings center on retaining water in the bowel.
Goal fit
The saved findings connect the eligible ingredients mainly to retaining water in the bowel.
Dose adequacy
The eligible amount reaches the saved comparison target.

Pathways40

Support is concentrated on retaining water in the bowel, with limited breadth.
Depth
The strongest saved connection is to retaining water in the bowel.
Breadth
One digestive area reaches the saved coverage threshold; the contribution remains narrow.

Evidence24

Magnesium leads the saved findings, with preparation and population qualifications relevant to interpreting benefit.
Evidence strength
Magnesium leads the saved evidence assessment; the supplied reference qualifications limit how confidently this predicts everyday digestive benefit.
Studied preparation
The magnesium declaration does not match the studied preparation accepted for this finding.

Magnesium · 500 mg

Magnesium can help address fatigue and weakness caused by low magnesium intake. Its role in energy metabolism does not establish an added energy boost when intake is adequate. The declared amount reaches the full saved comparison allowance, with no additional benefit established above nutritional needs. The 500 mg per serving exceeds the supplied comparison range; retained credit does not establish suitability at that exposure.

How this product is rated for Energy

Ingredient fit92

Magnesium receives the main saved allowances. The counted amounts reach the full comparison ranges.
Goal fit
Magnesium supplies the main saved ingredient connection; other actives and broader product purposes affect focus.
Dose adequacy
The counted amounts reach the full saved comparison allowances; exceeding them does not establish added energy benefit.

Pathways0

No contribution is assigned to the configured energy pathways. Nutritional correction remains a distinct role.
Depth
No contribution is assigned to the configured energy pathways, despite the separate nutrient allowances.
Breadth
No configured energy pathway reaches the saved breadth criterion; this does not negate a nutrient’s role in correcting low intake.

Evidence88

Magnesium’s relevant benefit concerns fatigue from low intake. Its metabolic role does not establish additional energy in adults with adequate intake.
Evidence strength
Magnesium anchors the saved evidence finding; its allowance does not establish extra energy in adults with adequate intake.
Studied preparation
The counted preparations receive the saved comparison allowance, without establishing superior energy effects for a particular form.

Formulation logic100

The counted ingredients meet the minimum amount criterion and have no missing required partner or identified configured conflict.
Partner coverage
No required ingredient partner is missing for the counted ingredients.
Conflicts
No configured ingredient conflict was identified; this does not establish individual suitability.
Effective doses
The counted ingredients meet the saved minimum amount criterion; this threshold does not establish a fatigue-treatment dose.

Magnesium supports electrolyte balance and the regulation of blood-vessel tone. Its blood-pressure effects in supplementation trials are small or inconsistent, so a substantial declared amount does not guarantee a noticeable change. The listed magnesium form does not establish a superior heart-health effect.

How this product is rated for Heart Health

Ingredient fit92

Magnesium provide the principal connection to heart health. The declared active amount reaches the supplied comparison range.
Goal fit
Magnesium give the formula a focused connection to electrolyte and vascular-tone balance.
Dose adequacy
The declared magnesium amount reaches the saved comparison range; this does not predict the size of a benefit.

Pathways57

The findings center on electrolyte and vascular-tone balance. This is a concentrated contribution rather than coverage of several heart-related routes.
Depth
Magnesium concentrate the findings on electrolyte and vascular-tone balance.
Breadth
The findings cover electrolyte and vascular-tone balance, with no comparable coverage of the other assessed routes.

Evidence89

Magnesium's evidence concerns limited blood-pressure effects, with mixed findings.
Evidence strength
Magnesium supplies the strongest evidence contribution, with inconsistent blood-pressure results.
Studied preparation
The saved preparation comparison accepts the relevant nutrient declarations; this does not establish superiority of the listed forms.

Formulation logic100

No unmet partner requirement or listed stimulant or high-sodium conflict was identified. The ingredients counted for amount coverage reach the supplied comparison threshold.
Partner coverage
The contributing ingredients have no unmet partner requirement in the supplied findings.
Conflicts

Ingredient fit92

Magnesium account for the relevant ingredient roles. Their amounts reach the saved comparison ranges.
Goal fit
Magnesium provide the relevant connection; the relevant ingredients are focused on these roles.
Dose adequacy
The relevant declared amounts reach the saved comparison range; this does not make them proven effective daily doses.

Pathways54

The main connection is vascular tone and sodium balance. Coverage extends to vascular tone and sodium balance.
Depth
The strongest connection is vascular tone and sodium balance, rather than broad cardiovascular outcomes.
Breadth
The supported coverage is concentrated in vascular tone and sodium balance.

Evidence79

Magnesium leads the supplied evidence among qualifying ingredients. The accepted preparations do not remove the limits of the underlying findings.
Evidence strength
Magnesium provides the strongest supplied evidence among the qualifying ingredients, with the population and outcome limits described above.
Studied preparation
The qualifying preparations match those accepted in the supplied comparison; this does not establish superior benefit for their forms.

Formulation logic100

The relevant ingredients need no missing partner and no listed conflict was found. Their qualifying amounts do not establish added benefit from combining them.
Partner coverage
The relevant ingredients can contribute independently or have the required partner; no extra combined benefit is established.
