About this product

A combined 300 mg from guarana extract and whole guarana of guarana supplies the central active in a focused capsule format. The extracted-plus-whole approach offers useful quantity but no concentration ratio or caffeine yield supports short-term energy, while any cognitive benefit is likely limited to temporary alertness.

The formula is more convincing for energy than for broad cognitive support. Without caffeine standardization, users cannot compare its stimulant effect with a measured caffeine product.

The active amount is clearly stated and good value for the stated amount supports practical use. Missing caffeine yield, extract-marker detail, and fuller use guidance remain the decisive limitations.

Who is it for
  • Adults seeking short-term stimulant support
  • Caffeine-tolerant users who can start cautiously
  • People who prefer a capsule guarana product
Best for
  • Short-term energy
  • Temporary alertness
  • Users comfortable with unstandardized caffeine

Pros

  • Clearly states the guarana amount
  • Offers good value for the stated amount
  • Simple capsule delivery

Cons

  • Does not disclose caffeine milligrams
  • Stimulant strength may vary
  • Limited support beyond temporary alertness

Warnings

  • The caffeine amount is undisclosed, so begin cautiously rather than treating extract weight as caffeine weight.
  • Combining this with coffee, energy drinks, pre-workouts, or stimulant medicines may cause jitteriness, palpitations, anxiety, or insomnia.
  • Caffeine-sensitive users, pregnant people, and those with rhythm or uncontrolled blood-pressure concerns should avoid an unquantified stimulant load.

Product analysis

75 out of 100
A focused guarana capsule with a substantial stated amount and good value for the stated amount. Unquantified caffeine makes the actual stimulant dose unpredictable.

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

Nutrient quality78

Extract plus whole guarana provides a useful amount, though caffeine yield and extract strength are missing. The focused guarana formula fits short-term energy and alertness use.

Ingredient transparency72

Listed weights are mostly clear, with no proprietary blend hiding a combined amount. Complete use directions and inactive ingredients are not supplied, while repeated entries make the active contribution difficult to interpret.

Customer satisfaction68

The average rating is good, and the review count is moderate. No review text is supplied to assess recurring complaints or purpose-specific experience.

Value for money82

The formula quality and active contribution reasonably justify the cost. Serving value is good for the disclosed amount.

B+ Composition And Label DisclosureF Composition And Label Disclosure
Guarana 200 mg lists two guarana sources: 200 mg of seed extract and 100 mg of guarana. The extract line reports 22% caffeine and a 44 mg caffeine yield, but the plain guarana line has no caffeine amount, so the combined disclosure remains incomplete.
