Caffeine is not prohibited under the 2026 World Anti-Doping Agency Prohibited List. That does not make every guarana pouch automatically suitable for every athlete or competition.
Caffeine is permitted but monitored
WADA’s current resources separate prohibited substances from the Monitoring Program. USADA explains that caffeine is permitted in WADA-governed sport and monitored for patterns of use. Rules can change annually, so athletes and support personnel should check the current list rather than rely on an old article or package claim.
Guarana is a caffeine source
A pouch containing extract standardized to 20% caffeine must be evaluated by total caffeine, not by the word “botanical.” At an exact assay, 250 mg extract theoretically provides 50 mg caffeine. Other ingredients may contribute additional caffeine or introduce separate compliance concerns.
The larger anti-doping risk is often the complete formula
A product can contain permitted caffeine while also containing an undeclared or prohibited stimulant through intentional formulation, supplier error or cross-contamination. Athletes remain responsible for substances found in their samples. Review every active ingredient and use certification or batch-testing programs recognized by the relevant sporting body where available.
Performance evidence does not define an ideal pouch
Research on caffeine in sport often uses controlled oral doses in drinks, capsules or gum. It should not be used to promise that a particular guarana pouch improves performance, acts within a fixed time or works without adverse effects. Dose, timing, habitual use, sleep and event duration all change the practical outcome.
A procurement checklist for team environments
- Current full ingredient list and caffeine per pouch
- Lot-specific testing and manufacturing traceability
- Assessment of every added botanical or stimulant
- Independent certification where the team requires it
- Review against federation, league and national rules
