Score breakdown

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

Dosage quality

4.0/10

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).

Multi-ingredient formulation analysis

Dose 4/10 · Bioavailability 0.4/10 · Coherence 0/10

Dose quality suggests a diluted formulation.

Ingredient form quality suggests suboptimal ingredient forms.

A proprietary blend limits independent dose verification.

Some ingredient forms are not declared on the label.

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

Score summary

The formula stays relatively clean on excipients. The main limitation is that proprietary blend prevents independent dose verification.

Strengths

The formula stays relatively clean on excipients
The safety profile looks solid
The supporting evidence profile is relatively strong

Weaknesses

Proprietary blend prevents independent dose verification
Berberine: below clinically studied range
Resveratrol: chemical form not specified on label

Final verdict

Not a strong option overall. The product is materially held back by weaker formulation coherence.
