Green Tea and Guarana in Olivaro: Caffeine, Catechins and Cautions
Olivaro lists guarana seed extract third and green tea leaf extract seventh in its 200 mg blend. Both contain caffeine, but the label gives no caffeine amount. Because the whole blend is at most 400 mg a day, total caffeine cannot come near FDA's 400 mg daily reference (FDA, Caffeine: how much is too much?). Green tea extracts have rare liver reports (NCCIH, Green Tea).

The basics
What are green tea and guarana?
Both are plants that contain caffeine. Green tea leaves also hold catechins, plant compounds studied for weight. Guarana is a Brazilian vine whose seeds are rich in caffeine (NCCIH, Green Tea) (MSKCC, Guarana).
Many effects people link to guarana come from that caffeine.

Caffeine
How much caffeine is in Olivaro?
The label does not say. Guarana is a caffeine source whose amount is often left off labels, and Olivaro follows that pattern (NIH ODS, Dietary Supplements for Weight Loss).
The label still sets hard limits. The full blend is 200 mg per dropper. Label order caps guarana at about 67 mg and green tea at about 29 mg per dropper (21 CFR 101.36 (eCFR)). And an extract is never pure caffeine.
| Item | 1 dropper | 2 droppers |
|---|---|---|
| Whole blend | 200 mg | 400 mg |
| Guarana extract, most possible | about 67 mg | about 133 mg |
| Green tea extract, most possible | about 29 mg | about 57 mg |
| Both extracts together, most possible | about 95 mg | about 190 mg |
| Caffeine in those extracts | Not published | Not published |
So Olivaro's caffeine is a fraction of those extract weights. It cannot reach 400 mg a day. It is probably small, but sensitive people may still notice it.
Daily total
How much caffeine a day is safe?
For most healthy adults, FDA cites 400 mg a day as an amount not generally linked to harm. That is about two to three 12-oz cups of coffee (FDA, Caffeine: how much is too much?).
The number that counts is your total from every source. Coffee, tea, soda, energy drinks and pre-workout powders all add up, and Olivaro adds an unknown but small amount on top.
- Too much caffeine can cause a fast heart rate, palpitations, insomnia, anxiety and jitters (FDA, Caffeine: how much is too much?).
- People who are pregnant, breastfeeding, sensitive to caffeine or on certain medicines should ask a provider about their limit.
Catechins
Does green tea extract help with weight or blood sugar?
Only a little, if at all. Catechins plus caffeine may have a modest effect on body weight, and studies tested 141-1,207 mg of catechins a day (NCCIH, Green Tea) (NIH ODS, Dietary Supplements for Weight Loss).
Olivaro's green tea extract is at most about 57 mg a day at 2 droppers, and catechins are only part of that. Even the lowest studied catechin amount is out of reach.
No reliable evidence shows that green tea extract treats diabetes. Health agencies say supplements should never replace diabetes care (NCCIH, Diabetes and Dietary Supplements). The Olivaro claims vs evidence page sets every sales claim next to the research.
Safety
Can green tea extract harm the liver?
Rarely, yes. Liver injury has been reported in some people using green tea products, mostly concentrated extracts in pills (NCCIH, Green Tea). Green tea catechin extracts are named as a liver concern in weight-loss research too (NIH ODS, Dietary Supplements for Weight Loss).
Olivaro's amount is small, but the risk is not zero and the strength is unknown. People with liver disease should ask a doctor first.
Yellow skin or eyes, dark urine, pain in the upper right belly or unusual tiredness.
At high doses, green tea lowers blood levels of nadolol, a beta-blocker for blood pressure (NCCIH, Green Tea). If you take nadolol, ask your pharmacist whether any green tea product fits your routine.

Order nowStimulants
Who should be careful with guarana?
People sensitive to stimulants, people with heart or blood pressure problems, and people on blood thinners. Guarana's common side effects are nausea and insomnia (MSKCC, Guarana).
Do not stack
Guarana may not be safe with other stimulants, such as energy drinks or stimulant weight-loss products.
High doses
Large amounts can cause vomiting, heartbeat changes, high blood pressure and seizures. Those doses are far above Olivaro's.
Ask first
Guarana may raise bleeding risk with warfarin. How much this matters in practice is not settled.
Talk to your doctor before you change any diabetes medicine, and mention every supplement, including caffeine sources. The Olivaro side effects guide covers the rest of the blend.
Quick check
Is Olivaro a good fit if you limit caffeine?
It may be, since the amount is small, but check yourself first. The last question below asks about caffeine sensitivity.
Our take
What is the bottom line on green tea and guarana in Olivaro?
They mostly add a little caffeine. Neither reaches a studied amount, and the label leaves out the caffeine total.
Reassuring
- Total caffeine cannot come near 400 mg a day
- Extract amounts are small by label math
Worth knowing
- No caffeine figure printed
- Rare liver reports with green tea extracts
- Guarana cautions with stimulants and warfarin
If you track caffeine closely, call the order desk at +1 (855) 889-3137 and ask whether a caffeine figure is available.

FAQ
Green tea and guarana in Olivaro: common questions
Does Olivaro have caffeine?
Yes, it contains some caffeine from guarana seed extract and green tea leaf extract, but the label gives no amount. Because the whole blend is 200 mg per dropper, the caffeine is small and cannot come near FDA's 400 mg daily reference for healthy adults.
Will Olivaro keep me awake?
Probably not for most people, since the caffeine amount is small. Very sensitive people may notice it, and ginseng and African mango in the blend are also linked to poor sleep. If your sleep changes, check your total caffeine and tell your doctor.
Is guarana stronger than coffee?
Guarana seeds are rich in caffeine, and much of guarana's effect comes from that caffeine. What matters is the total amount you take. Olivaro's label does not give a caffeine figure, but label math limits the guarana extract to about 67 mg per dropper at most.
Is green tea extract safe for the liver?
For most people, yes, but rare liver injury has been reported, mainly with concentrated extracts in pills. People with liver disease should ask a doctor before using any green tea extract. Stop and get checked if you notice yellow eyes, dark urine or upper belly pain.
Can I drink coffee while taking Olivaro?
Most healthy adults can, as long as total caffeine stays within about 400 mg a day, roughly two to three 12-oz cups of coffee. Olivaro adds a small, unlisted amount. People who are pregnant, sensitive or on certain medicines should ask a provider about their limit.
Does guarana interact with warfarin?
It may. Guarana is listed as possibly raising bleeding risk with blood thinners such as warfarin, although how much this matters in practice is not settled. Anyone on warfarin should ask a doctor or pharmacist before taking a product with guarana, including Olivaro.
Does green tea lower blood sugar?
There is no reliable evidence that green tea extract treats diabetes or lowers blood sugar in a meaningful way. Catechins plus caffeine may have a modest effect on weight at amounts far above what Olivaro can hold. It should never replace diabetes medicine.
