Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
The dominant bioactive constituent, present at 2-4 times the concentration found in coffee beans by weight; responsible for guarana's stimulant, ergogenic and thermogenic effects.
Polyphenols thought to slow caffeine absorption and to contribute antioxidant activity.
Minor stimulant alkaloids alongside caffeine.
Characteristic phenylpropanoid glycosides largely unique to Rhodiola rosea, used as a standardisation marker for commercial extracts.
Phenylethanoid glycosides considered key adaptogenic and antioxidant constituents.
Contribute to the anti-inflammatory and antioxidant activity of the root.

Safety, Cautions & Contraindications
Guarana contains very high levels of caffeine (2–4 times that of coffee by weight). All the cautions of caffeine apply — avoid in cardiac arrhythmia, hypertension, anxiety disorders, insomnia, and during pregnancy and breastfeeding. Should not be combined with other stimulants, MAOIs, or medications affected by caffeine. Risk of dependence and withdrawal symptoms with prolonged high-dose use.
Duke (2002) rates guarana as ++ and notes CNS-stimulant, anti-aggregant, diuretic, and thermogenic activities, primarily due to its high caffeine content (3–5%). It has positive chronotropic and inotropic effects on the heart. Duke flags guarana as genotoxic and mutagenic at the experimental level (score 1), which warrants caution with high-dose supplementation. Contraindicated in cardiovascular disease, anxiety disorders, peptic ulcers, and during pregnancy. Interactions include potentiation of other stimulants and anticoagulants (Duke, 2002).
Generally well tolerated. May cause agitation, insomnia, or vivid dreams in sensitive individuals — take in the morning. Avoid in manic episodes or severe anxiety. Theoretical interactions with MAOIs, SSRIs, and CNS stimulants. Avoid during pregnancy and breastfeeding.

Botanical Description
Woody climbing shrub or liana (Sapindaceae) in its native forest habitat, though often cultivated and pruned as a shrub. Leaves are alternate and pinnately compound with 5 leaflets. Small greenish-white flowers are borne in axillary panicles, followed by a red-orange, three-lobed capsule that splits open to reveal black seeds partly covered by a white aril - a fruit likened in Indigenous Amazonian folklore to a staring eye.
Succulent perennial herb (Crassulaceae), 15-40 cm tall, with a thick, fleshy, branching rhizome that has a rose-like fragrance when cut - the origin of the name 'rosea'. Leaves are fleshy, greyish-green, oval to oblong. Small yellow (occasionally reddish) flowers are clustered in dense terminal heads; the species is dioecious, with separate male and female plants. Fruit follicles turn red as they ripen.[3]
Habitat
Native to the Amazon basin, particularly Brazil, where it has long been cultivated by Indigenous peoples (notably the Sateré-Mawé); grows in tropical, humid lowland forest conditions.
Native to arctic and mountainous regions of Europe, Asia and North America (circumpolar), growing in cold, rocky, high-altitude or high-latitude terrain - cliffs, rocky slopes and tundra - tolerating harsh, exposed conditions.[3]
Harvesting
Ripe fruit capsules are hand-harvested as they split open; seeds are removed, roasted, and traditionally ground into a paste with water and shaped into sticks for storage, or dried and powdered.
Rhizome and root are dug from plants at least a few years old (traditionally 4-5 years), typically in autumn, then cleaned and dried. Wild populations grow slowly, so cultivated sources are increasingly preferred for sustainability.[3]
Traditional Uses
Guarana seed has a long Amazonian Indigenous tradition as a stimulant tonic for fatigue and stamina and as a ceremonial and social beverage. Its very high caffeine content (greater by weight than coffee beans) underlies its modern use for cognitive performance, physical endurance and metabolic support, supported by clinical trials.[5]
Rhodiola has a long tradition of use across Scandinavian, Russian and Central Asian folk medicine as a tonic for cold-climate hardiness, physical endurance and mental stamina. It is classified as a modern 'adaptogen', and clinical trials support benefits for stress-related fatigue, mood and cognitive performance.[1, 3]

Pairings
Not documented
Rhodiola and eleuthero (Siberian ginseng) are classic adaptogens combined in traditional and studied fixed formulas to build resistance to stress and fatigue; used together their stress-protective effects are complementary.[17, 18]
Rhodiola and schisandra are adaptogens co-formulated in clinically studied combinations for stress, fatigue and mental performance; combined use is intended to be synergistic rather than harmful.[17, 18]
