Score breakdown

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

Dosage quality

5.6/10

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 5.6/10 · Bioavailability 0.5/10 · Coherence 0/10

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

Copper: dose within clinically studied range (evidence B). The main limitation is that proprietary blend prevents independent dose verification.

Strengths

Copper: dose within clinically studied range (evidence B)
Vitamin-d: high-bioavailability form declared (Cholecalciferol (D3))

Weaknesses

Proprietary blend prevents independent dose verification
Critical safety flag limits final score
Vitamin-a: chemical form not specified on label

Final verdict

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