Zeaxan Green Tea Extract: Last in the Blend, With Cautions Worth Knowing
Zeaxan green tea extract is the last of 11 ingredients, so by label order it could weigh up to about 55 mg. The label marks it 50% and prints no amount or caffeine figure. The NCCIH links rare liver injury to green tea extract capsules, and it can lower levels of two medicines.

What is Zeaxan green tea extract?
Zeaxan green tea extract is the eleventh and final name in the blend. The label writes it as "Green Tea Extract (50%)". Because blends list the heaviest ingredient first, last place means it is the smallest share. It is also the line with the most safety notes on the panel.
The label does not say why it is there. It does not give an amount, and it does not say what the 50% refers to. The most likely reading is a standardized extract, with the 50% marking the strength of some group of compounds. The label never names the compounds.
Key facts
- Green tea extract (50%) is listed last, 11 of 11, in the 600 mg blend.
- By label order it could weigh up to about 55 mg. The real amount is not published.
- If 50% refers to catechins, about 27 mg at most. EFSA flagged 800 mg of EGCG a day or more.
- The NCCIH links rare liver injury to green tea extract capsules.
- It can lower blood levels of nadolol and atorvastatin.
- The label does not say if the extract has caffeine.
How much Zeaxan green tea extract could one serving hold?
The ceiling for the last ingredient is the smallest of all. Eleven ingredients share 600 mg, and each one must weigh at least as much as the one after it. So the eleventh can weigh at most about 55 mg. That is a ceiling, and the real amount may be lower.
Now apply the 50%. If it refers to catechins, the active tea compounds, then 50% of 55 mg is about 27 mg at most. The European Food Safety Authority flagged liver markers rising at 800 mg of EGCG a day or more, in a 2018 opinion on green tea catechins. That is a daily figure from a different setting. Against it, the Zeaxan ceiling of about 27 mg is small. Still, because the real amount is not published, we only compare ceilings, never real doses.
| Item | Figure | Note |
|---|---|---|
| Place in the blend | 11 of 11 | Smallest share by label order |
| Most it could weigh | About 55 mg | A ceiling, not an amount |
| Catechins if 50% means that | About 27 mg at most | The label does not say |
| Level EFSA flagged | 800 mg EGCG a day or more | Liver markers rose |
| Amount per 2 capsules | Not published | Ask the order desk if it matters to you |
What does the NCCIH say about Zeaxan green tea extract?
The National Center for Complementary and Integrative Health, updated February 2025, says rare liver injury has been linked to green tea extract capsules. The word to hold on to is rare. Drinking green tea is a different matter from taking a concentrated extract in a capsule, and the sources on this site speak about the capsule form.
Even so, the label asks anyone with a known medical condition to consult a physician first. If you have liver disease or past liver problems, the green tea extract is one of the reasons to ask before the first capsule. Stop and call your doctor if something feels wrong after you begin. Bring the bottle so the doctor can read all 11 lines.
Which medicines matter with Zeaxan green tea extract?
Green tea extract can lower the blood levels of two medicines named in the sources: nadolol, a heart drug, and atorvastatin, a cholesterol drug. If the level drops, the medicine may then work less well.
- Nadolol and atorvastatin are the two named. Tell your doctor or pharmacist if you take either.
- Other heart and cholesterol medicines may also be affected. The label says to talk to your doctor before use if you take any medicine.
- Do not stop or change a prescribed medicine on your own because of this page.
The full list of medicine notes for the blend is in the medicines post. It covers ginkgo and blood thinners, cinnamon and blood sugar medicines, and this one.
What about caffeine in Zeaxan green tea extract?
The label does not say if the extract contains caffeine. This site's capsule table notes that the caffeine is small and comes from the green tea extract, and that the amount is not printed. With a ceiling of about 55 mg for the whole extract, the caffeine in a serving is likely small. We cannot give a number, and we do not guess one.
If you are careful with caffeine for any reason, mention it to your pharmacist. They can weigh it against the rest of your day.

Our view
Green tea extract is last on the list and loud on the caution panel. The risk it carries is rare, and the amount in a serving is not published. It is still the one ingredient that most justifies a word with your doctor if you have a liver condition or take nadolol or atorvastatin.
For everyone else, the practical step is the same as for the rest of the blend: read the label, ask before you start and keep your eye exams. This page is general information, not medical advice.
