Guarana Extract is a concentrated botanical extract derived from the seeds of Paullinia cupana, a climbing plant native to the Amazon basin in Brazil. Standardised to contain 22.55% caffeine (HPLC), Guarana Extract provides a naturally sourced, sustained-release caffeine ingredient distinctly different from synthetic caffeine — due to the tannin-bound matrix of the guarana seed that slows caffeine absorption, resulting in a gentler, longer-lasting energy effect with reduced jitteriness.
Guarana seeds contain approximately twice the caffeine concentration of coffee beans, making this standardised extract one of the most potent natural caffeine sources available for energy, sports performance, and cognitive enhancement supplement formulations.
Applications:
- Energy Drinks & Supplements (natural caffeine source for energy and alertness formulations)
- Sports Nutrition (pre-workout energy, endurance, and focus blends)
- Weight Management (thermogenic fat-burning supplements, metabolism boosters)
- Cognitive Health (focus, alertness, and mental performance supplements)
Key Features & Benefits:
- 22.55% caffeine (HPLC) – potent standardised natural caffeine source
- Tannin matrix provides sustained-release energy – smoother than synthetic caffeine
- Natural Amazonian botanical with strong consumer appeal
- Halal-certified & food-grade quality
- Suitable for capsule, beverage, and powder formulations
22.55% caffeine: what that means for your dose
This extract is standardised to caffeine by HPLC. At 22.55%, 100 mg of extract carries about 22.5 mg of caffeine and about 440 mg of extract carries about 100 mg. Guarana seeds also contain smaller amounts of theobromine and theophylline and a large share of tannins (catechins and proanthocyanidins). Total caffeine per serving is what regulators and consumers look at, so add guarana caffeine to any other caffeine in the formula.
Labelling and limits
Many markets require a caffeine statement or a warning for children and pregnant women once caffeine passes a set level, and some limit caffeine per serving in foods and drinks. Check the rules of your target market before you fix the dose. Batch-to-batch caffeine should be confirmed on each COA, because the label figure is only as good as the assay.
Formulation notes
Guarana is bitter and astringent from its tannins, so drinks and gummies need flavour masking. It is often paired with L-Theanine in focus formulations. Store it sealed, cool and dry.
What the research says
- A 2023 meta-analysis of 8 placebo-controlled studies (328 participants, single doses of 37.5–500 mg guarana containing 4.3–100 mg caffeine) found that guarana gave a small improvement in response time on cognitive tasks, with no effect on accuracy. Averaged across all cognitive measures, the effect was very small and not significant. The authors could not tell whether the effect came from the caffeine or from other compounds, and called for studies comparing guarana with matched caffeine doses. [1]
