Decision summary

CONSIDERSOLID OPTION

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

Best for

People prioritizing high absorption and overall formula quality.

Consider another option if

You want fewer compromises on formulation quality.

Score breakdown

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

Dosage quality

8.0/10

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 8/10 · Bioavailability 6.3/10 · Coherence 0/10

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

Score summary

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

Strengths

Leucine: dose within clinically studied range (evidence A)
Tryptophan: dose within clinically studied range (evidence B)
Leucine: high-bioavailability form declared (L Leucine)

Weaknesses

Formula coherence is weak: diluted, decorative or overly complex
Calcium: below clinically studied range
Potassium: below clinically studied range

Final verdict

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