Tap a module to see what it measures. A 0 can reflect missing disclosure, not just a negative result.
Dosage quality
9.0/10
Strong dosing for the intended goal
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).
Evidence inferred from established knowledge, not directly linked studies
Supports the formula, but not a major driver: Clinical dosing guidance is limited for this ingredient.
No supporting studies or dosing references are currently available for this ingredient.
ℹ Evidence is strong, but dose is below the optimal range
One of the weaker points: Dose is below the ranges usually used for stronger effects. The label does not specify the form, so absorption quality cannot be verified.
