Green Tea Extract in Neuro Recall: EGCG, Liver Safety and Side Effects
Quick answerGreen tea extract is a concentrated form of tea leaf, standardized in Neuro Recall to at least 50% EGCG. It is 5th in the blend, so a serving holds up to 127 mg of extract. Rare liver injury has been reported, mainly with extract pills. The caffeine content is not published. Ask your doctor first if you have liver disease.

Green tea extract is the 5th of ten items in the Neuro Recall blend. The label standardizes it to at least 50% EGCG. This page explains what that means, how much could be in a serving, and why the liver comes up whenever extract pills are discussed.
What is green tea extract?
It is green tea leaf in concentrated form. Makers soak the leaves, pull out the active compounds and dry them into a powder. A small amount of powder can hold what many cups of tea would.
Green tea comes from the same plant as black and oolong tea, Camellia sinensis. Green tea leaves are steamed or pan-fired soon after picking, which keeps more of their natural catechins.
The Supplement Facts panel lists it as Green Tea (leaf) Extract, not less than 50% EGCG. It sits next to L-theanine, an amino acid that also comes from tea.
What is EGCG?
EGCG is the main catechin in green tea. The letters stand for epigallocatechin gallate. Catechins are a group of plant compounds, and EGCG is the one found in the largest amount.
Extracts are often sold by EGCG percentage, because it gives a way to compare batches. A label of not less than 50% means at least half the extract's weight should be EGCG.
Researchers study EGCG in lab and animal work for many reasons. That interest is not proof of a benefit in people, and no memory dose has been set.

How much EGCG is in Neuro Recall?
The exact amount is unknown. Blend items are listed heaviest first (21 CFR 101.36), so the 5th item can weigh at most 635 ÷ 5, or 127 mg. At least half of whatever extract is present should be EGCG.
The table shows how that plays out. The first row is the ceiling. The middle rows are examples to show the math, not real figures.
| Scenario | Extract weight | EGCG (50% or more) | Note |
|---|---|---|---|
| Extract at its 127 mg ceiling | 127 mg | At least 63.5 mg | Highest the label allows |
| Extract at 90 mg | 90 mg | At least 45 mg | Example only |
| Extract at 50 mg | 50 mg | At least 25 mg | Example only |
| Actual amount | Not printed | Not printed | The blend split is not published |
Green tea extract and the liver: what is the risk?
The risk is rare but real. NCCIH says liver injury has been reported, mainly with green tea extract taken as pills, and that it is uncommon (NCCIH, Green tea). Brewed green tea as a drink is not where those reports center.
Neuro Recall holds a modest amount of extract. Still, we cannot rule anything out for one person, and the label does not print the exact amount.
One more liver note. The blend lists cinnamon first, with the species shown only as Cinnamomum spp. Cassia cinnamon contains coumarin, which is linked to liver effects (NCCIH, Cinnamon). The label does not say which cinnamon is used. See the cinnamon bark entry for more.
Signs of a liver problem
Stop taking it and call your doctor the same day if you notice yellow skin or eyes, dark urine, pale stools, pain in the upper right belly, nausea that will not settle, or tiredness that is new and heavy.
Does Neuro Recall contain caffeine?
We do not know, and neither does the label. Regular green tea contains caffeine, and extracts can keep it unless they are decaffeinated. The Neuro Recall label does not list caffeine and does not say whether the extract is decaffeinated.
If you are sensitive to caffeine, start on a morning you can watch how you feel. Jitters, a racing heart or trouble sleeping are reasons to stop and ask your doctor. You can also ask the seller at [email protected], though our files hold no answer yet.
Green tea extract side effects
Most people who take green tea products have no trouble. When problems do occur, they fall into a few groups. The side effects page covers the rest of the formula.
Liver injury
Rare, but serious. Linked mainly to extract pills. Watch for yellow skin, dark urine or belly pain.
Stomach upset
Nausea or an uneasy stomach. Many people find a meal helps, though this is a general tip, not a label rule.
Caffeine effects
Jitters or poor sleep, if the extract carries caffeine. The amount is not published.
Stacking extracts
Weight-loss and energy products often add green tea extract too. Your total intake adds up.
Green tea extract vs a cup of green tea
They are not the same thing. A cup is dilute and sipped slowly. An extract is concentrated and swallowed at once. That difference is why safety notes focus on pills.
| Point | A cup of green tea | Green tea extract in Neuro Recall |
|---|---|---|
| Form | Hot water poured over leaves | Dried, concentrated powder in a capsule |
| EGCG per serving | Varies by tea and brewing | Standardized: at least 50% of the extract weight |
| Caffeine | Present in regular green tea | Not published for Neuro Recall |
| Liver reports | Not the focus of reports | Most reports involve extract pills (NCCIH, Green tea) |
| How fast you take it in | Sipped over minutes | Swallowed all at once |
Who should ask a doctor first?
Ask your doctor or pharmacist before starting if you are
- Anyone with liver disease, hepatitis or past liver trouble
- People who drink alcohol most days
- Anyone already taking a green tea, weight-loss or energy supplement
- People who are sensitive to caffeine or have heart rhythm problems
- Anyone taking prescription medicine
- Anyone pregnant or nursing (the label says do not use)
Bring the bottle so your doctor can see the full blend. The berberine page covers the drug interactions in the same capsule, and the how to use page explains the daily routine.
Honest note: no memory dose to compare
Green tea extract earns its place on many labels, but there is no memory dose to measure Neuro Recall against. Our dose table lists it as not comparable for that reason. The amount here is small and unknown.
That leaves liver safety as the main thing to know. For the parts of the formula studied for memory, read the ginkgo biloba page.
Green tea extract FAQ: questions people ask
Is green tea extract bad for your liver?
Rarely, it can be. NCCIH says liver injury has been reported, mainly with green tea extract in pill form, and that it is uncommon. Brewed tea has not shown the same pattern.
What is EGCG?
EGCG (epigallocatechin gallate) is the main catechin in green tea. Catechins are plant compounds, and extracts are often sold by how much EGCG they contain.
How much EGCG is in Neuro Recall?
The label does not say. Green tea extract can weigh up to 127 mg a serving, and at least half of whatever amount is there must be EGCG, so EGCG is somewhere below 127 mg.
Does Neuro Recall have caffeine?
The caffeine content is not published. Green tea extracts can carry caffeine unless they are decaffeinated, and the label does not say which kind is used.
What are the side effects of green tea extract?
Liver injury is the rare but serious one NCCIH notes. Stomach upset is worth watching for, and if the extract carries caffeine, jitters or trouble sleeping are possible too.
What are the signs of liver damage from supplements?
Yellow skin or eyes, dark urine, pale stools, pain in the upper right belly, nausea or unusual tiredness. Stop the supplement and call your doctor the same day.
Is green tea extract the same as drinking green tea?
No. An extract packs the compounds of many cups into a small pill, and liver reports center on pills rather than brewed tea.
Does green tea extract help memory?
No memory dose has been established. Green tea compounds are of research interest, but there is no proof that a small extract dose helps recall.
Can I take Neuro Recall with other green tea products?
Ask your doctor first. Some weight-loss and energy products also contain green tea extract, and stacking extracts raises your total intake.
Should I take green tea extract with food?
The Neuro Recall label does not say. Many people find that a meal eases stomach upset with supplements, but that is a general tip, not a label instruction.
