Tap a module to see what it measures. A 0 can reflect missing disclosure, not just a negative result.
Dosage quality
1.5/10Dosing looks weaker than ideal
Checks whether labeled ingredient amounts fall within clinically studied ranges (not just regulatory minimums). Low/0 can reflect under-dosing or missing amounts (e.g., proprietary blends).

Dose quality suggests a diluted formulation.
Ingredient form quality suggests suboptimal ingredient forms.
A proprietary blend limits independent dose verification.
This is a multi-ingredient product. The score reflects formulation quality, not efficacy for a specific health goal.
Vitamin-d: high-bioavailability form declared (Cholecalciferol (D3)). The main limitation is that proprietary blend prevents independent dose verification.

ℹ Dose is below the optimal range with moderate supporting evidence
One of the weaker points: Dose is below the ranges usually used for stronger effects.
Scientific evidence

Skin Appendage Disorders • 2017
PMID: 28786550.0
ℹ Evidence is strong, but dose is below the optimal range
A clear drag on the formula: Dose is likely below clinically useful levels.
Scientific evidence
Wald et al. meta-analysis of folic acid and cardiovascular risk

PMID: 15364185.0
Daly et al. RCT on folate supplementation and homocysteine reduction
New England Journal of Medicine • 1996
PMID: 9521168.0
⚠ Dose is below commonly used clinical ranges
A clear drag on the formula: Dose is likely below clinically useful levels. The label does not specify the form, so absorption quality cannot be verified.
Clinical dosing guidance
Based on established dosing ranges used in clinical practice.
⚠ Limited evidence exists, and dose is below effective threshold
A clear drag on the formula: Dose is likely below clinically useful levels.
Scientific evidence
Hodges et al. review on pantothenic acid physiology and human deficiency implications
Advances in Nutrition • 2020
⚠ Strong evidence exists, but dose may be too low to be effective
A clear drag on the formula: Dose is likely below clinically useful levels. The declared form supports strong absorption.
Scientific evidence

Evidence inferred from established knowledge, not directly linked studies
Adequate, but not a key strength: Clinical dosing guidance is limited for this ingredient. The declared form supports strong absorption.
No supporting studies or dosing references are currently available for this ingredient.
Important label or formulation details that may affect how this product should be interpreted.
Proprietary blend limits dose transparency
Exact ingredient amounts cannot be verified clearly.
Folate dose looks below clinically effective levels
Declared amount falls below ranges used in human trials.
Formula design looks less coherent than stronger alternatives
The formulation appears less focused than better-built options.
