Dosage quality
6.7/10Acceptable dosing, but not standout
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).

ℹ Evidence is strong, but dose is below the optimal range
Solid but not a standout: Dose is directionally useful, but not a standout strength. The declared form is acceptable, but not among the best-absorbed options.
Scientific evidence

Metabolism • 2012
PMID: 22162995.0
ℹ Evidence is strong, but dose is below the optimal range
This is a limiting factor: Dose is strong and within effective ranges. The declared form is not one of the better-absorbed options.
Scientific evidence

Cochrane Database of Systematic Reviews • 2011
PMID: 22553186.0
Prasad et al. RCT zinc supplementation and testosterone in elderly men
Nutrition • 1996
PMID: 8875519.0
⚠ 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
Martineau et al. meta-analysis vitamin D supplementation and respiratory infections
BMJ • 2017
PMID: 26864360.0
Bischoff-Ferrari et al. meta-analysis vitamin D fracture prevention
BMJ • 2009
PMID: 20198382.0
⚠ Moderate evidence exists, but dose is below effective threshold
This is a limiting factor: Dose is likely below clinically useful levels. The label does not specify the form, so absorption quality cannot be verified.
Scientific evidence
