How Much Caffeine Is in Guarana? Sugar Defender's Label
How much caffeine in guarana Sugar Defender holds is not printed anywhere on the bottle. Guarana seeds contain caffeine, and the extract is third in the blend, so a 1 mL serving holds at most 67 mg of extract. Green tea adds more caffeine. FDA's guide for most adults is 400 mg a day.

The amount01
How much caffeine is in Sugar Defender's guarana?
Nobody outside the company can say, because the label prints no caffeine figure and no weight for guarana.
A supplement has to list the blend total and the order of its parts, but not each part (21 CFR 101.36 (eCFR)). Caffeine is not given its own line here.
What we can say is a limit. Guarana is third of 22 in a 200 mg blend, so one 1 mL serving holds at most 200 divided by 3, about 67 mg of guarana extract. Caffeine would be only a portion of that extract, not all of it.
An even split would give about 9 mg of extract. So the extract is a small part of each serving, but the exact caffeine stays unknown.
The source02
Why does guarana contain caffeine?
Guarana is a seed that naturally contains caffeine, and many of its effects are credited to that caffeine, according to Memorial Sloan Kettering (MSKCC, Guarana).
The sales page puts the words "Stimulates Your Metabolism" beside it. We read that as a hint that you may feel a lift, not as a proven change in how the body works.
Green tea leaf extract is the label's other caffeine source, seventh in the blend with a ceiling of 29 mg (NCCIH, Green Tea).
| Ingredient | Place | Most per 1 mL | Caffeine printed? |
|---|---|---|---|
| Guarana seed extract | 3rd | 67 mg | No |
| Green tea leaf extract | 7th | 29 mg | No |
The limit03
How much caffeine is too much in a day?
FDA cites 400 mg a day, about two to three 12-oz cups of coffee, as an amount not generally linked to harm in healthy adults (FDA, Caffeine: how much is too much?).
Too much can cause a fast heartbeat, palpitations, insomnia, anxiety and jitters. People who are pregnant, breastfeeding or sensitive, or who take certain medicines, should ask a provider.
Many people forget the drinks they already have. One strong coffee, a cola and an energy drink can add up fast before the drops are counted.
The label caps the drops at one 1 mL serving a day, which keeps the total small. The risk is stacking: coffee, tea, energy drinks and the drops together. Count the cups you already have.
- Sleep trouble after the dose: take it earlier in the day.
- Racing heart or shaking: stop and call a provider.
- High doses of guarana can raise blood pressure and change heartbeat (MSKCC, Guarana).
Timing04
When should you take caffeinated drops?
Early in the day suits most people. The label names no time, so the choice is yours.
Caffeine can linger for hours. A morning 1 mL dose leaves a long gap before bed, while an evening dose may not. If you work nights, place the dose at the start of your waking hours instead of the clock's morning.
Do not double up to make up for a missed day. The label directs 1 mL a day, and a second dose would double the caffeine along with everything else in the bottle.
The dial below shows one way to place the dose in a day.
- One fixed time, such as 7:30
1 mL once a day, as the label says. It names no time; a morning slot keeps the caffeine away from sleep.
- A walk after a meal
The DPP lifestyle group aimed at 150 active minutes a week, and its diabetes risk fell by 58%.
- Plates and portions
The CDC says losing 5-7% of body weight helps prevent type 2 diabetes.
- Night, 7 to 9 hours
Guarana and green tea add caffeine, so a morning dose suits light sleepers better than a late one.
Habits are drawn from the Diabetes Prevention Program (NIDDK, Diabetes Prevention Program) and CDC (CDC, Prediabetes); caffeine guidance from FDA (FDA, Caffeine: how much is too much?). The label names no time of day; the morning slot is our suggestion. Follow your label and your doctor.
Who should skip05
Who should avoid guarana caffeine?
Anyone told to limit caffeine, people with heart rhythm or blood pressure problems, and pregnant or nursing women should check with a physician first.
Guarana may be unsafe with other stimulants. It may raise bleeding risk with blood thinners such as warfarin (MSKCC, Guarana).
Never stop a prescription because you added a supplement. Our Sugar Defender side effects page lists more cautions.
FAQ06
Guarana caffeine questions
Is the caffeine in guarana stronger than coffee?
Not in this bottle. Guarana is capped near 67 mg of extract per serving and caffeine is a fraction of that. The exact caffeine is unprinted, so compare by how you feel.
Is the caffeine in Sugar Defender from guarana alone?
Yes. Guarana and green tea both contain caffeine, and the label gives no amount for either. If you avoid caffeine, ask your provider before taking the drops.
Can caffeine from guarana affect sleep?
Yes, insomnia is a common side effect. Memorial Sloan Kettering lists it for guarana. If you sleep badly, move the dose to the morning or skip it.
