Score breakdown

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

Dosage quality

3.1/10

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 proprietary blend prevents independent dose verification.

Strengths

The supporting evidence profile is relatively strong
The safety profile looks solid

Weaknesses

Proprietary blend prevents independent dose verification
Berberine: below clinically studied range
Vitamin-k2: chemical form not specified on label

⚠ Strong evidence exists, but dose is below effective threshold

One of the weaker points: Dose is likely below clinically useful levels. The declared form is acceptable, but not among the best-absorbed options.

ℹ Evidence is strong, but dose is below the optimal range

A clear drag on the formula: Dose is below the ranges usually used for stronger effects. The label does not specify the form, so absorption quality cannot be verified.
