Decision summary

CONSIDERAVERAGE

You care a lot about label clarity and want fewer unknowns.

Score breakdown

Tap a module to see what it measures. A 0 can reflect missing disclosure, not just a negative result.

Dosage quality

3.9/10

Dosing 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).

Score summary

The formula stays relatively clean on excipients. The main limitation is that formula coherence is weak: diluted, decorative or overly complex.
