You want fewer compromises on formulation quality.

Score breakdown

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

Dosage quality

6.7/10

Acceptable 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).

Multi-ingredient formulation analysis

Dose 6.7/10 · Bioavailability 6.3/10 · Coherence 0/10

This is a multi-ingredient product. The score reflects formulation quality, not efficacy for a specific health goal.

Score summary

Quercetin: dose within clinically studied range (evidence B). The main limitation is that formula coherence is weak: diluted, decorative or overly complex.

Strengths

Quercetin: dose within clinically studied range (evidence B)
Quercetin: high-bioavailability form declared (Quercetin Dihydrate)

Weaknesses

Formula coherence is weak: diluted, decorative or overly complex
Alpha-lipoic-acid: below clinically studied range
Green-tea: below clinically studied range

Final verdict

A middling option. It may be usable, but weaker formulation coherence makes better alternatives worth comparing.
