Score breakdown
Tap a module to see what it measures. A 0 can reflect missing disclosure, not just a negative result.
Dosage quality
8.6/10Strong 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).
