Product analysis

61 out of 100

Niacinamide 500 mg supplies a nutrient needed for normal skin function, with the clearest benefit when intake is low. The high amount does not establish added cosmetic benefit when nutritional needs are already met.

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

Nutrient Quality24

The niacin form is not clearly disclosed, while calcium carbonate is identified. The available information does not allow a firm comparison of their quality or absorption.

Ingredient Transparency81

The amounts of both ingredients are disclosed, so the serving is straightforward to compare. Calcium is identified as carbonate, but the niacin form remains unclear.

Value For Money88

The serving offers favorable value for its niacin content. Calcium adds uncertainty because there is not enough information to judge its value separately.

Customer Satisfaction87

Customer feedback is positive across a large number of ratings. That broad response is reassuring about satisfaction, but it does not establish skin or heart benefits.

Product Focus46

The formula has a clear nutritional role for skin when niacin intake is low. Its relevance to cardiovascular support is much less convincing because niacinamide does not share the evidence described for nicotinic acid.

Niacin at 500 mg per serving supplies a nutrient needed for normal skin function. Correcting inadequate intake can matter for skin, but high amounts do not imply added cosmetic benefit in adequately nourished adults.

How this product is rated for Skin Health

Ingredient fit82

The relevant ingredients contribute through skin-related nutritional or structural roles, with the saved amount assessment varying by ingredient.
Goal fit
Skin-related ingredients sit alongside ingredients serving other functions, making the focus less direct.
Dose adequacy
The assessed amounts reach the saved comparison levels, without implying that more provides greater skin benefits.

Pathways0

The saved assessment assigns no contribution to its specified skin pathways.
Depth
None of the specified skin pathways receives a contribution in the saved finding.
Breadth
No skin area reaches the saved threshold for substantial coverage.

Evidence61

The strongest saved finding concerns vitamin b3 (niacin); practical skin benefits remain dependent on the preparation and nutritional need.
Evidence strength
Vitamin B3 (Niacin) supplies the strongest saved finding at an assessed amount; this is not a prediction of individual skin improvement.
Studied preparation
The assessed ingredients meet the saved preparation comparison.

Formulation logic100

The assessed ingredients have no missing required partner or matched conflict.
Partner coverage
No required supporting ingredient is missing for the assessed contribution.
Conflicts
No listed conflict was matched in the supplied assessment.
Effective doses
All assessed ingredients clear the saved minimum amount threshold.

Niacin · 500 mg

Niacinamide 500 mg is declared on the label, but it is not the nicotinic acid preparation linked to triglyceride-marker evidence; the supplied references give it no cardiovascular marker contribution. Calcium is also an unrelated active. As a result, no pathway or studied-dose support is established for this product. This does not show niacinamide is ineffective for every purpose.

How this product is rated for Cardiovascular Support

Ingredient fit42

The label gives a niacinamide amount, but this preparation is not credited for the cardiovascular markers described here.
Goal fit
Niacinamide is not linked to the relevant marker evidence, and calcium is off-goal.
Dose adequacy
The listed niacinamide amount cannot be used as a nicotinic acid dose.

Pathways0

No cardiovascular pathway is supported by this preparation in the supplied facts.
Depth
No pathway has relevant coverage from niacinamide here.
Breadth
None of the target pathways has credited coverage.

Evidence0

The supplied lipid-marker evidence concerns nicotinic acid, not niacinamide.
Evidence strength
No ingredient reaches a dose with evidence for these cardiovascular markers.
Studied preparation
No credited ingredient is present in a studied cardiovascular preparation.

Formulation logic75

No conflict or partner gap was identified, but the listed niacinamide gets no marker credit.
Partner coverage
No credited ingredient is shown to be missing a required partner.
Conflicts
No applicable conflict was identified in the saved facts.
Effective doses
The listed amount is for niacinamide, not the preparation used in the marker comparison.
