Score breakdown

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

Dosage quality

4.3/10

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 4.3/10 · Bioavailability 5.2/10 · Coherence 0/10

Dose quality suggests a diluted formulation.

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

Score summary

Collagen-peptides: high-bioavailability form declared (Collagen Hydrolysate). The main limitation is that formula coherence is weak: diluted, decorative or overly complex.

Strengths

Collagen-peptides: high-bioavailability form declared (Collagen Hydrolysate)
Copper: high-bioavailability form declared (Copper Bisglycinate)
Zinc: high-bioavailability form declared (Zinc Bisglycinate)

Weaknesses

Formula coherence is weak: diluted, decorative or overly complex
Vitamin-e: below clinically studied range
Vitamin-c: below clinically studied range

Final verdict

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