Features:

Epigallocatechin-3-gallate — EGCG is a naturally occurring galloylated flavan-3-ol and the quantitatively dominant catechin in green tea leaves from Camellia sinensis. It is formally classified as a dietary polyphenol, catechin and investigational pleiotropic bioactive compound. EGCG has concentration-, oxidation-, metal- and cellular-context-dependent activity: it can function as an antioxidant and NRF2-associated cytoprotective agent in normal tissues, but may generate reactive oxygen species and induce stress-mediated death in susceptible cancer cells. It is not an approved anticancer drug, and purified high-dose extracts are pharmacologically and toxicologically distinct from brewed green tea.

Primary mechanisms (ranked):

  1. Biphasic redox modulation, including direct radical scavenging and metal chelation at lower exposure, but auto-oxidation, hydrogen-peroxide generation and pro-oxidant stress under permissive cancer-cell culture conditions.
  2. Suppression of proliferative and survival signalling, particularly PI3K–AKT–mTOR, NF-κB, receptor tyrosine kinase, STAT and context-dependent MAPK pathways.
  3. Mitochondrial dysfunction and intrinsic apoptosis through mitochondrial membrane-potential loss, cytochrome-c release and caspase activation.
  4. Cell-cycle arrest through modulation of cyclins, cyclin-dependent kinases, p21, p27 and p53-associated signalling.
  5. Inhibition of invasion, epithelial–mesenchymal transition and extracellular-matrix degradation through reduced FAK, MMP-2, MMP-9, uPA and related motility pathways.
  6. Suppression of HIF-1α–VEGF signalling, angiogenesis and hypoxia adaptation.
  7. Metabolic disruption involving reduced glycolysis, glucose transport and context-dependent mitochondrial energy production.
  8. Epigenetic modulation, including experimental inhibition or altered expression of DNMTs, HDACs and EZH2.
  9. Modulation of proteostasis, autophagy, endoplasmic-reticulum stress and unfolded-protein responses.
  10. NRF2 activation as a secondary adaptive mechanism, generally cytoprotective in normal cells but potentially protective or treatment-resistant in some cancers.
  11. Chemosensitization or radiosensitization in selected experimental models; treatment protection, antagonism or normal-tissue radioprotection can also occur depending on dose, schedule and therapy.

Bioavailability / PK relevance: Oral bioavailability is low and highly variable because EGCG is chemically unstable near neutral or alkaline pH, has limited intestinal permeability, undergoes extensive methylation, glucuronidation and sulfation, and is influenced by food and microbiota. Plasma concentrations after tea consumption are usually submicromolar, while large supplemental doses may transiently produce low-micromolar exposure. Fasting can increase systemic exposure but may also increase hepatic toxicity risk. Nanoencapsulation, lipid carriers and other delivery systems improve exposure experimentally but are not established anticancer treatments.

In-vitro vs systemic exposure relevance: Many anticancer experiments use approximately 10–100 µM EGCG, whereas conventional oral administration generally produces submicromolar to low-micromolar plasma concentrations. Thus, many direct cytotoxic, glycolytic, mitochondrial and kinase effects occur at concentrations substantially exceeding typical achievable systemic exposure. EGCG can also oxidize in culture media and generate extracellular hydrogen peroxide, creating experimental effects that may not translate directly in vivo.

Clinical evidence status: Extensive preclinical evidence; multiple small human biomarker, prevention and early-phase studies; limited randomized evidence for selected premalignant or recurrence-prevention settings; no established therapeutic efficacy against active cancer and no regulatory approval as an anticancer agent. A recent randomized colorectal adenoma study reported reduced recurrence, but this does not establish treatment efficacy for invasive colorectal cancer. Ongoing clinical studies continue to investigate prevention and adjunctive applications.

Safety and interactions: Brewed green tea is generally well tolerated, whereas concentrated green-tea extracts and purified EGCG have been associated with dose-dependent aminotransferase elevations and rare clinically significant liver injury. Doses around 800 mg EGCG per day have generated a regulatory safety signal, and a universally safe supplemental dose has not been established. Risk may be higher with fasting administration, pre-existing liver disease or multi-ingredient weight-loss products. EGCG can bind non-heme iron, alter drug transporters or metabolic enzymes, and modify exposure to some medications; oncology use should therefore be reviewed for drug-specific interactions.



EGCG (Epigallocatechin Gallate) is found in green tea. 100 times more effective than Vitamin C and 25 times more effective than Vitamin E at protecting cells from damage associated with oxidative stress.
EGCG Epigallocatechin Gallate (Green Tea) -Catechin
Summary:
1. Concentration is a factor that could determine whether green tea polyphenols act as antioxidants or pro-oxidants.
2. Poor bioavailability: taking EGCG capsules without food was better.
3. Cancer dosage 4g/day (2g twice per day)? with curcumin may help (another ref says 700–2100 mg/d). FDA says <800mg/day (hepatotoxicity)
4. EGCG is susceptible to oxidative degradation.
5. “As for the pH level, the acidic environments enhance the stability of EGCG”.
6. “EGCG may enhance nanoparticle uptake by tumor cells”
7. Might be iron chelator (removing iron from cancer cells)
8. Claimed as synergistic effect with chemotherapy ( cisplatin, bleomycin, gemcitabine.
9. May suppress glucose metabolism, interfere with VEGF, downregulate NF-κB and MMP-9, down-regulation of androgen-regulated miRNA-21.
10. Take with red pepper powder, Capsicum ratio 25:1 (based on half life, they did every 4 hr) (chili pepper vanilloid capsaicin).
11. EGCG mediated ROS formation can upregulate CTR1 expression via the ERK1/2/NEAT1 pathway, which can increase the intake of chemotherapeutic drugs such as cisplatin in NSCLC cells and act as a chemosensitizer [58]
12. Matcha green tea has highest EGCG (2-3X) because consuming leaf.
13. EGCG is an ENOX2 inhibitor.
14. Nrf2 activator in both cancer and normal cells. This example of lung cancer show both directions in different cell lines, but both toward optimim level.
Biological activity, EGCG has been reported to exhibit a range of effects, including:
    Antioxidant activity: 10-50 μM
     Anti-inflammatory activity: 20-50 μM
     Anticancer activity: 50-100 μM
     Cardiovascular health: 20-50 μM
     Neuroprotective activity: 10-50 μM

Drinking a cup (or two cups) of green tea (in which one might ingest roughly 50–100 mg of EGCG from brewed tea) generally results in peak plasma EGCG concentrations in the range of approximately 0.1 to 0.6 μM.

With higher, supplement-type doses (e.g., oral doses in the 500 mg–800 mg range that are sometimes studied for clinical benefits), peak plasma concentrations in humans can reach the low micromolar range, often reported around ~1–2 μM and in some cases up to 5 μM.

Reported values can range from about 25–50 mg of EGCG per gram of matcha powder.
In cases where the matcha is exceptionally catechin-rich, the content could reach 200–250 mg or more in 5 g.

-Peak plasma concentration roughly 1 to 2 hours after oral ingestion.
-Elimination half-life of EGCG in plasma is commonly reported to be in the range of about 3 to 5 hours.

Supplemental EGCG
Dose (mg)   ≈ Peak Plasma EGCG (µM)
~50 mg          ≈ 0.1–0.3 µM
~100 mg         ≈ 0.2–0.6 µM
~250 mg         ≈ 0.5–1.0 µM
~500 mg         ≈ 1–2 µM
~800 mg or higher  ≈ 1–5 µM

50mg of EGCG in 1g of matcha tea(1/2 teaspoon)

Studies on green tea extracts have employed doses roughly equivalent to 300–800 mg/day of EGCG. Excessive doses can cause liver toxicity in some cases.

Methods to improve bioavailability
-Lipid-based carriers or nanoemulsions
-Polymer-based nanoparticles or encapsulation
-Co-administration with ascorbic acid (vitamin C)
-Co-administration of adjuvants like piperine (perhaps sunflower lecithin and chitosan) -Using multiple smaller doses rather than one large single dose.
-Taking EGCG on an empty stomach or under fasting conditions, or aligning dosing with optimal pH conditions in the GI tract, may improve its absorption.(acidic environment is generally more favorable for its stability and absorption).
– EGCG is more stable under acidic conditions. In the stomach, where the pH is typically around 1.5 to 3.5, EGCG is less prone to degradation compared to the more neutral or basic environments of the small intestine.
- At neutral (around pH 7) or alkaline pH, EGCG undergoes auto-oxidation, reducing the effective concentration available for absorption.
– Although the stomach’s acidic pH helps maintain EGCG’s stability, most absorption occurs in the small intestine, where the pH is closer to neutral.
– To counterbalance the inherent instability in the intestine, strategies such as co-administration of pH-modifying agents (like vitamin C) are sometimes used. These agents help to maintain a slightly acidic environment in the gut microenvironment, potentially improving EGCG stability during its transit and absorption.
– The use of acidifiers or buffering agents in supplements may help preserve EGCG until it reaches the absorption sites.

-Note half-life 3–5 hours.
- low BioAv 1%? despite its limited absorption, it is rapidly disseminated throughout the body

Alzheimer’s disease relevance: EGCG has substantial preclinical neuroprotective evidence but no established clinical efficacy for Alzheimer’s disease. Proposed actions include inhibition or remodelling of amyloid-β aggregation, altered amyloid precursor protein processing, metal chelation, reduced tau-associated injury, suppression of neuroinflammation, mitochondrial protection and activation of NRF2-associated antioxidant defences. Most positive findings derive from biochemical, cellular or animal models, and brain exposure after conventional oral administration is uncertain. EGCG should therefore be classified as preclinical or exploratory for Alzheimer’s disease rather than as a validated disease-modifying therapy.

4680- EGCG,    The Potential of Epigallocatechin Gallate in Targeting Cancer Stem Cells: A Comprehensive Review
- Review, Var, NA
CSCs↓, major bioactive green tea polyphenol (-)-epigallocatechin gallate (EGCG) has been fruitful in downgrading cancer stemness signaling and CSC biomarkers in cancer progression.
EMT↓, Cancer stemness is intricately related to epithelial-mesenchymal transition (EMT), metastasis and therapy resistance, and EGCG has been evidenced to regress all these CSC-related effects
TumMeta↓,
RadioS↑, By inhibiting CSC characteristics EGCG has also been evidenced to sensitize the tumor cells to radiotherapy and chemotherapy.
ChemoSen↑,
BioAv↓, concern about its bioavailability, stability and efficacy against spheroids raised from parental cells. Therefore, novel nano formulations of EGCG and adjuvant therapy of EGCG with other phytochemicals or drugs or small molecules may have a better pr

4682- EGCG,    Human cancer stem cells are a target for cancer prevention using (−)-epigallocatechin gallate
- Review, Var, NA
CSCs↓, EGCG inhibits the transcription and translation of genes encoding stemness markers, indicating that EGCG generally inhibits the self-renewal of CSCs.
EMT↓, EGCG inhibits the expression of the epithelial-mesenchymal transition phenotypes of human CSCs.
ChemoSen↑, Green tea prevents human cancer, and the combination of EGCG and anticancer drugs confers cancer treatment with tissue-agnostic efficacy.
