The basics
What is a guarana supplement?
A guarana supplement is made from the seeds of guarana, a climbing plant from the Amazon. Memorial Sloan Kettering says the seeds contain caffeine, and the plant is promoted for appetite, fatigue and energy (MSK, Guarana).
SodaBurn lists "guarana seed extract" as the fourth of 21 names in its blend. The label prints no amount for guarana alone, only the blend total of 15.47 mg per 1 ml. We have not seen a photo of the Supplement Facts panel, so check your bottle.
The front of the label says "Promotes Clean Energy & Focus†". Guarana is one of two caffeine sources in the blend. "Clean" is not a measured term, and the dagger leads to the FDA statement that the claim is not evaluated.
| Name on the label | Guarana Seed Extract |
|---|---|
| What it is | Seed extract of a caffeine-rich Amazon plant |
| Place on the label | 4 of 21 names in the blend, in label order |
| Printed amount | Not printed. Name 4 of 21 in a 15.47 mg per 1 ml blend, so at most 3.87 mg per 1 ml |
| Daily Value | Not printed |
| Amount used in research | FDA: about 400 mg of caffeine a day is not generally linked to harm in most healthy adults. The label does not print the caffeine content of the extract |
| How the label compares | At most 3.87 mg of extract per 1 ml of blend, about 1% of 400 mg even if all of it were caffeine, which it is not |
| Strength of evidence | Contains caffeine; evidence for weight is weak and short; NIH sees a possible modest effect in small, mostly combination trials |
| Marketed or traditional use | Sold for energy and appetite |
| Main caution | A stimulant. Nausea and insomnia are common; high doses can cause fast heartbeat and high blood pressure. May raise bleeding risk with blood thinners. |
The number
How much guarana caffeine could SodaBurn hold?
The label prints no caffeine amount, and guarana weighs at most 3.87 mg per dropperful. FDA rules list blend names from the heaviest to the lightest, so the name in place 4 can weigh at most 15.47 divided by 4 (21 CFR 101.36, Proprietary blends).
That is a ceiling for the whole seed extract. Guarana is not pure caffeine, so the caffeine in it would be lower. FDA says about 400 mg of caffeine a day is not generally linked to harm in most healthy adults (FDA, How much caffeine is too much). The ceiling is at least 103 times smaller than that.
The catch is that caffeine adds up. Green tea extract is the second caffeine source, and coffee, tea, soda and energy drinks all count. The bars show the gap for four blend names.
The evidence
Does guarana weight loss research show anything?
Guarana weight loss research is weak. Memorial Sloan Kettering cites no weight loss evidence for it and calls the evidence for its uses weak (MSK, Guarana).
The NIH sees a possible modest effect from caffeine sources, but the trials are short, small and mostly of combination products, so the credit is hard to assign (NIH ODS, Weight loss supplements). A review of 54 trials found too little proof to recommend any herbal medicine for weight loss (Maunder 2020, Herbal medicines for weight loss).
| Question | What the sources say |
|---|---|
| Weight evidence for guarana alone | None cited; evidence called weak (MSK, Guarana) |
| Caffeine sources in general | Possible modest effect, short trials (NIH ODS, Weight loss supplements) |
| Herbal medicines overall | Insufficient evidence to recommend (Maunder 2020, Herbal medicines for weight loss) |
| Study of SodaBurn | We found none |
The label front says "Helps Control Cravings & Appetite†". We found no study of guarana that backs that wording at this amount, so we make no such claim.
Safety
What are guarana side effects?
Guarana side effects come mostly from caffeine. Memorial Sloan Kettering lists nausea and insomnia as common, and says high doses may cause vomiting, heart rhythm changes, high blood pressure and seizures (MSK, Guarana).
FDA names these caffeine warning signs: a rapid heartbeat, palpitations, high blood pressure, insomnia, anxiety, jitters, upset stomach, nausea and headache (FDA, How much caffeine is too much). A ceiling of 3.87 mg is small, but people differ in how they react.
Chest pain, trouble breathing, fainting or a racing heartbeat that will not settle: call 911. If you are pregnant, trying to conceive or nursing, ask a provider about caffeine limits first (FDA, How much caffeine is too much).

Can guarana interact with blood thinners or stimulants?
Yes. Guarana may raise bleeding risk with blood thinners such as warfarin, and combining it with other stimulants may be unsafe (MSK, Guarana).
Keep taking prescribed medicine. Never stop or change it because of a supplement. Ask a doctor or pharmacist first if you take blood thinners, stimulants or ADHD medicine, blood pressure or heart medicine, diabetes medicine or seizure medicine. Also ask before surgery.
