You care a lot about ingredient quality and effectiveness.

Score breakdown

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

Dosage quality

7.2/10

Generally solid dosing

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 7.2/10 · Bioavailability 1.8/10 · Coherence 0/10

Ingredient form quality suggests suboptimal ingredient forms.

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

Score summary

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

Strengths

Vitamin-a: dose within clinically studied range (evidence A)
Vitamin-b12: dose within clinically studied range (evidence B)
Zinc: dose within clinically studied range (evidence A)

Weaknesses

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

Final verdict

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