Two caffeine sources
Green Tea Extract and Guarana in Glyco Reset: How Much Caffeine Is in a Dropper?
Green tea extract and guarana seed extract both contain caffeine, and both sit in the Glyco Reset blend, but the label prints no caffeine amount. MedlinePlus says up to 400 mg a day is generally not harmful for most people. A dropper's caffeine is simply unknown.

The unknown01
How much caffeine is in Glyco Reset?
Nobody outside the maker can say how much caffeine is in a Glyco Reset dropper, because the label prints no caffeine amount.
Two blend names carry caffeine: Guarana Seed Extract (fourth) and Green Tea Leaf Extract (seventh). Sloan Kettering says guarana seeds contain caffeine, and NCCIH says the same of green tea (MSK, Guarana (About Herbs)) (NCCIH, Green Tea).
A cup helps as a yardstick. MedlinePlus lists 95 to 200 mg in 8 oz of coffee, 70 to 100 mg in an energy drink and 14 to 60 mg in tea, and treats 400 mg a day as generally fine for most adults (MedlinePlus, Caffeine). Where one dropper lands on that scale is anyone's guess, so we offer none.
Green tea02
Is green tea extract safe to take as a supplement?
Green tea as a drink has no reported safety concerns, but green tea extract supplements are a different product and have been linked to liver injury.
NCCIH calls liver injury uncommon with extracts, though reported, and lists nausea, constipation, stomach discomfort and higher blood pressure as other effects (NCCIH, Green Tea). LiverTox has logged over 100 cases that showed clinical signs. Amounts ran from roughly 800 mg to 1.8 g of extract daily, and the three cases it describes in detail all recovered (LiverTox, Green Tea).
Sloan Kettering notes a USP label line that tells people with a liver problem not to use it (MSK, Green Tea (About Herbs)). Those amounts are well above what a shared 200 mg blend could hold, yet the green tea share is unprinted, so nothing can be ruled in or out.
| Item | What the source says | Glyco Reset label |
|---|---|---|
| Liver cases (LiverTox) | About 800 mg to 1.8 g of extract a day | Amount not shown |
| Single doses tolerated | Up to 1.6 g | Amount not shown |
| Whole blend | Not applicable | 200 mg for 21 names |
Side by side03
How far apart are the studied amounts and the label?
The label's 200 mg is a shared total, and the liver-case amounts sit at four times that or more.
That is arithmetic only: 800 mg divided by 200 mg is four. It does not mean the drops are low in green tea, because the split is unprinted (21 CFR 101.36 (eCFR), Supplement Facts and proprietary blends).
The comparison. NIH recounts a 1997 trial giving adults with type 2 diabetes 1,000 mcg of chromium picolinate daily. The Adequate Intake, by contrast, is 20 to 35 mcg. (NIH ODS, Chromium fact sheet for professionals)
Read it with care. The studied amount comes from a different product, group and time span. It is not a recommended or effective dose, and no trial tested Glyco Reset.
The comparison. LiverTox cites 400 mg three times daily as a typical gymnema supplement amount. The label's 200 mg has to stretch across twenty-one names. (LiverTox, Gymnema)
Read it with care. The studied amount comes from a different product, group and time span. It is not a recommended or effective dose, and no trial tested Glyco Reset.
The comparison. LiverTox reports liver injury cases at roughly 800 mg to 1.8 g of extract daily. The whole blend totals 200 mg. (LiverTox, Green Tea)
Read it with care. The studied amount comes from a different product, group and time span. It is not a recommended or effective dose, and no trial tested Glyco Reset.
Each full bar is the daily amount used in the one study or reference we cite. The filled part is the most the label could give per dropper: the whole 200 mg blend is shared by 21 names, so any one plant is a fraction of that. The label also does not say whether each name is a powder or an extract, so even this comparison is rough.
Guarana04
What are guarana side effects?
Most guarana side effects trace back to caffeine. Sloan Kettering names nausea and insomnia, then heartbeat changes, higher blood pressure and seizures at high amounts.
Its page also recounts case reports tied to an energy drink: a fast pulse, skipped beats and a seizure. Stimulants should not be stacked with it, and blood thinners raise a bleeding concern (MSK, Guarana (About Herbs)).
None of this shows Glyco Reset caused anything. It simply tells a caffeine-sensitive reader what to ask.
- Add up the day's other caffeine, from coffee, tea, soda and energy drinks.
- Tell your doctor about a racing heart, jitters or poor sleep.
- If caffeine keeps you awake, avoid a late-evening dropper.
Before you start05
Who should ask a doctor before taking caffeine-containing drops?
People with anxiety, a heart rhythm problem, high blood pressure, liver disease or pregnancy should ask a doctor first, since MedlinePlus lists these as caffeine cautions.
Keep taking prescribed medicine and tell your doctor and pharmacist about every supplement (MedlinePlus, Metformin). Only blood tests diagnose diabetes or prediabetes (NIDDK, Diabetes Tests & Diagnosis). Severe low blood sugar, fainting or a seizure means calling 911 (Mayo Clinic, Hypoglycemia).

Claims check06
Do green tea and guarana belong on a blood sugar label?
Neither plant has an official source we read tying it to blood sugar, so their place in this blend rests on the brand's choice.
NCCIH reports a modest effect of green tea on body weight, not blood sugar, and says nothing about guarana and diabetes (NCCIH, Green Tea) (NCCIH, Diabetes and Dietary Supplements). The brand's "healthy glucose utilization" wording is a starred statement, with no study cited.
The ingredients page shows both names in context, and the side effects page gathers every caution. Compare pack options only after you have checked your own caffeine limit.
FAQ07
Green tea, guarana and caffeine: questions people ask
Does Glyco Reset contain caffeine?
Likely yes: two listed names, Guarana Seed Extract and Green Tea Leaf Extract, carry caffeine. No caffeine amount is printed in what we have, so the dropper's content is unknown. Read your own bottle.
Is the caffeine in guarana different from coffee?
Sloan Kettering says guarana seeds contain caffeine and gives no amount. We found no source comparing guarana caffeine with coffee in a liquid blend, so we make no comparison.
Can green tea extract hurt your liver?
It has happened. LiverTox records over 100 cases tied to green tea extract, at amounts larger than this blend could hold, while NCCIH calls it uncommon. Yellow skin or dark urine means stopping and calling a doctor.
What does EGCG have to do with green tea extract?
EGCG is a compound in green tea that LiverTox links to the liver cases. The Glyco Reset label does not print an EGCG amount or a standardization, so it cannot be checked.
Can you take guarana with blood pressure medicine?
Sloan Kettering says guarana can raise blood pressure at high amounts and warns about stimulants and blood thinners. Ask a pharmacist before the first dropper and keep taking prescribed medicine.
How much caffeine is too much in a day?
For most adults MedlinePlus treats up to 400 mg a day as generally fine, and it urges care with anxiety, heart rhythm problems, high blood pressure and pregnancy. Total every source, not only the drops.
Is Glyco Reset safe if I am sensitive to caffeine?
No one can say, since the amount is unprinted. If caffeine already gives you jitters or poor sleep, ask a doctor or pharmacist before opening the bottle.
