1 use researched3 sourced claims
Detox My Life researched guarana extract under one use, because the same substance means something different in each use. Every claim below carries its evidence tier, how sure the research is that it applies here, and the sources it cites. The level is computed by the app's own deterministic engine, so the page says exactly what the app would.

ConsensusRestrictedconfidence 100%
Guarana extract can interact with various medications, including stimulant drugs (e.g., amphetamines, ephedrine, nicotine, cocaine), blood thinners (anticoagulant/antiplatelet drugs like warfarin, aspirin), certain antidepressants (MAOIs), adenosine, asthma medications, estrogens/birth control pills, antibiotics, antifungal medications, and medications for seizures or heart disease, potentially leading to serious adverse effects or altering drug efficacy.
- Why here
- When ingested, the caffeine and other bioactive compounds in guarana extract can influence drug metabolism and physiological responses, leading to potential drug-drug interactions.
- What would have to be true
- Ingestion of guarana extract concurrently with any of the listed medications. Individuals should consult a healthcare provider before combining guarana with any prescription or over-the-counter medications.

ConsensusMetabolicconfidence 100%
Ingestion of guarana extract, particularly in excessive or chronic amounts, can lead to adverse effects such as insomnia, nervousness, restlessness, stomach irritation, nausea, vomiting, increased heart rate and blood pressure, rapid breathing, tremors, delirium, agitation, and headaches due to its high caffeine content. Very high doses can cause serious issues like irregular heartbeats (arrhythmia, atrial fibrillation), seizures, and can be dangerous or even fatal.
- Why here
- Guarana extract is ingested, and its primary active component, caffeine, directly stimulates the central nervous system, cardiovascular system, and gastrointestinal system.
- What would have to be true
- Daily caffeine intake from all sources, including guarana, exceeding 400 mg, single servings above 200 mg, or chronic ingestion of doses greater than 250-300 mg daily. Individuals with pre-existing cardiovascular disease, anxiety, high blood pressure, glaucoma, or irritable bowel syndrome, as well as pregnant or lactating women and children, are particularly susceptible to adverse effects.

ConsensusClearedconfidence 100%
In the United States, guarana seed extract is approved by the FDA as a food additive for flavoring purposes under 21 CFR 172.510, but it is not classified as 'generally recognized as safe' (GRAS) for broader uses beyond flavoring.
- Why here
- This regulatory classification directly impacts how guarana extract can be legally incorporated into ingested food products and supplements.
- What would have to be true
- Ingestion of products containing guarana extract as a food additive or supplement.

Not researched here
The engine has no dossier for guarana extract when cooked with heat, in cold food, as a finishing ingredient, in heated food packaging or other uses. The app researches an ingredient for the use it infers from your product, so a scan fills these in; this page only shows what has already been researched and source-verified.
