PubMed ID: 25558905
Multivitamin drink containing guaraná improved decision speed and preserved HRV during testing — supports clearer, sustained cognition.
- Effects of Dietary Supplementation of a Microalgae Extract Containing Fucoxanthin Combined with Guarana on Cognitive Function and Gaming Performance
PubMed ID: 37111136
Microalgae+guaraná study in gamers showed modest reaction/attention improvements (but multi-ingredient), so moderate support.
- Effects of the active botanical blend "WKUP GT" on attention and cognitive functions after lunch in healthy volunteers
PubMed ID: 38367243
Low-caffeine guaraná beverage improved post-lunch attention and multitasking vs placebo — supports short-term clarity.
- Improved cognitive performance and mental fatigue following a multi-vitamin and mineral supplement with added guaraná (Paullinia cupana)
PubMed ID: 18077056
Large trial: multivitamin/mineral with guaraná improved sustained attention and reduced mental fatigue — consistent with clearer cognition.
- The Effects of Supplementation with a Vitamin and Mineral Complex with Guaraná Prior to Fasted Exercise on Affect, Exertion, Cognitive Performance, and Substrate Metabolism: A Randomized Controlled Trial
PubMed ID: 26225993
Guaraná-containing beverage slightly improved some memory tasks and lowered perceived exertion — modest cognitive benefit.
Energy & Fatigue (3)
- Guarana (Paullinia cupana) improves fatigue in breast cancer patients undergoing systemic chemotherapy
PubMed ID: 21612429
Randomized crossover in chemo patients: low-dose guaraná (50 mg BID) produced significant, clinically meaningful reductions in cancer-related fatigue vs placebo.
- Effects of the active botanical blend "WKUP GT" on attention and cognitive functions after lunch in healthy volunteers
PubMed ID: 38367243
Low-caffeine guaraná beverage improved post-lunch attention and multitasking — consistent with increased wakeful energy after lunch.
- Improved cognitive performance and mental fatigue following a multi-vitamin and mineral supplement with added guaraná (Paullinia cupana)
PubMed ID: 18077056
Multivitamin+guaraná attenuated task-related mental fatigue in a large randomized acute study.
Alertness (3)
- Effects of the active botanical blend "WKUP GT" on attention and cognitive functions after lunch in healthy volunteers
PubMed ID: 38367243
Post-lunch improvements in attention/multitasking with guaraná beverage indicate better alertness.
- Improved cognitive performance and mental fatigue following a multi-vitamin and mineral supplement with added guaraná (Paullinia cupana)
PubMed ID: 18077056
Multivitamin+guaraná improved vigilance across a 60-min cognitive battery, supportive of alertness benefits.
- Heart rate variability and cognitive function following a multi-vitamin and mineral supplementation with added guarana (Paullinia cupana)
PubMed ID: 25558905
Decision RT benefits and HRV maintenance imply more stable arousal/alertness during testing.
Weight management (3)
- Weight loss and delayed gastric emptying following a South American herbal preparation in overweight patients
PubMed ID: 11424516
Multi-herb product that included guaraná delayed gastric emptying and produced short-term weight loss in overweight patients.
- Acute effects of a herb extract formulation and inulin fibre on appetite, energy intake and food choice
PubMed ID: 23207186
Well-powered crossover: a guaraná-containing herbal tablet substantially reduced next-meal energy intake (~112 kcal, ~17% less) — strong support for weight-management mechanisms.
- An herbal supplement containing Ma Huang-Guarana for weight loss: a randomized, double-blind trial
PubMed ID: 11319627
Ephedra+guaraná formula led to short-term weight and fat loss vs placebo, but ephedrine/caffeine likely primary drivers — attribution to guaraná uncertain.
Appetite suppression (2)
- Acute effects of a herb extract formulation and inulin fibre on appetite, energy intake and food choice
PubMed ID: 23207186
Well-powered placebo-controlled crossover: guaraná-containing herbal tablet substantially reduced energy intake at the next meal (~112 kcal, ~17% less) — strong, direct evidence for mild appetite suppression.
- Weight loss and delayed gastric emptying following a South American herbal preparation in overweight patients
PubMed ID: 11424516
Multi-herb product including guaraná delayed gastric emptying and produced short-term weight loss — supports increased satiety and appetite suppression.
Productivity (1)
- Effects of Dietary Supplementation of a Microalgae Extract Containing Fucoxanthin Combined with Guarana on Cognitive Function and Gaming Performance
PubMed ID: 37111136
Gamers trial (microalgae+guaraná) showed modest improvements in multiple reaction-time/attention tests after 30 days.
Workout performance (1)
- Effects of Dietary Supplementation of a Microalgae Extract Containing Fucoxanthin Combined with Guarana on Cognitive Function and Gaming Performance
PubMed ID: 37111136
Gamers using microalgae+guaraná had modest improvements in reaction-time and attention tests, though no change in game scores — partial performance support.
Stress resilience (1)
- Heart rate variability and cognitive function following a multi-vitamin and mineral supplementation with added guarana (Paullinia cupana)
PubMed ID: 25558905
Multivitamin+guaraná preserved parasympathetic HRV early in testing vs declines in caffeine/placebo — suggests better short-term physiological stress handling.
