Score breakdown

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

Dosage quality

3.5/10

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 3.5/10 · Bioavailability 4.5/10 · Coherence 0/10

Dose quality suggests a diluted formulation.

Ingredient form quality suggests suboptimal ingredient forms.

A proprietary blend limits independent dose verification.

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

Score summary

Taurine: high-bioavailability form declared (Taurine). The main limitation is that proprietary blend prevents independent dose verification.

Strengths

Taurine: high-bioavailability form declared (Taurine)

Weaknesses

Proprietary blend prevents independent dose verification
Formula coherence is weak: diluted, decorative or overly complex
Vitamin-c: below clinically studied range

Final verdict

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

Ingredient Analysis & Evidence

A closer look at the main ingredients, how they influence the score, and the supporting evidence when available. Tap any ingredient to expand.

ℹ Dose is below the optimal range with moderate supporting evidence

This is a limiting factor: Dose is below the ranges usually used for stronger effects. The declared form supports strong absorption.

Scientific evidence

Meta-analysis

Bhatt et al. meta-analysis taurine and blood pressure

Hypertension Research • 2016

PMID: 26676042.0

Evidence inferred from established knowledge, not directly linked studies

Adequate, but not a key strength: Clinical dosing guidance is limited for this ingredient.

No supporting studies or dosing references are currently available for this ingredient.

ℹ Dose is below the optimal range with moderate supporting evidence

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.

Scientific evidence

Meta-analysis

Feringa et al. meta-analysis grape seed extract and blood pressure

British Journal of Clinical Pharmacology • 2011

PMID: 27444303.0

RCT

Vigna et al. RCT grape seed extract and oxidative stress

European Journal of Clinical Nutrition • 2003

PMID: 19942640.0

⚠ Strong evidence exists, but dose is below effective threshold

This is a limiting factor: Dose is likely below clinically useful levels. The declared form is acceptable, but not among the best-absorbed options.

Scientific evidence

Meta-analysis

Hemila & Chalker Cochrane review vitamin C and common cold duration

Cochrane Database of Systematic Reviews • 2013

PMID: 23440782.0

RCT

Journal of the American College of Nutrition • 2001

PMID: 11684527.0

⚠ Moderate evidence exists, but dose may be too low to be effective

One of the weaker points: Dose is likely below clinically useful levels. The label does not specify the form, so absorption quality cannot be verified.

Scientific evidence

Meta-analysis

Eidelman et al. meta-analysis vitamin E and cardiovascular endpoints

Archives of Internal Medicine • 2004
