Product analysis

45 out of 100

Guarana 200 mg offers a simple guarana supplement for people seeking short-term alertness, with benefits dependent on the preparation used.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality20

The guarana preparation is unspecified. Findings for a clearly defined extract cannot be assumed to apply to every guarana preparation.

Ingredient Transparency63

A guarana quantity is stated, but its preparation is not described. The herb's weight alone does not tell you the caffeine exposure.

Value For Money40

Value for money remains uncertain. The serving cost and guarana quantity do not establish a clear comparison of useful alertness support.

Customer Satisfaction74

Customer feedback is positive across several hundred reviews. The review base provides a useful range of opinions, though fewer than for heavily reviewed alternatives.

Product Focus51

The formula is narrowly centered on guarana and interest in alertness. The uncertain preparation and caffeine exposure make its practical effect harder to predict.
