About this item
- ONE CAPSULE, ONCE A DAY WITH FOOD: 500 mg of green tea extract (leaf, Camellia sinensis) equivalent to 10,000 mg dried leaf, standardized to 30% catechins and 50% EGCG, in a single vegetable capsule taken with food.
- STANDARDIZED FOR CONSISTENCY: Independently standardized to 50% EGCG (250 mg) and 30% total catechins (150 mg) per capsule, so potency doesn't vary bottle to bottle - unlike many green tea products whose real catechin content has been found to differ widely from the label claim.
- A REAL, LICENSED ANTIOXIDANT CLAIM: Source of antioxidants that help protect against the oxidative damage caused by free radicals - the authorized use on this product's Health Canada licence.
- MINIMAL CAFFEINE: Just 0.5% caffeine (about 2.5 mg per capsule) - roughly the caffeine content of a cup of decaffeinated coffee, far less than a cup of brewed tea or coffee.
- CLEAN, VEGAN FORMULA: Vegan vegetable capsules, non-GMO, gluten-free, dairy-free and soy-free, with no artificial colours, flavours or preservatives.
- A 4-MONTH SUPPLY: 120 capsules per bottle at 1 capsule per day - four months of consistent daily use before reordering.
- KNOW THE CAUTIONS: Rare, unpredictable cases of liver injury have been reported with green tea extract-containing products. Consult a health care practitioner before use if pregnant, breastfeeding, or if you have a liver disorder or an iron deficiency, and for use beyond 12 weeks.

What Green Tea Catechins Support
Research on green tea catechins and EGCG spans antioxidant protection, metabolism, cardiovascular health and more - CanPrev Green Tea's own licensed claim is the antioxidant use authorized under NPN 80130629.
Antioxidant Protection
Source of antioxidants that help protect against the oxidative damage caused by free radicals - the licensed use on this product's Health Canada NPN.
Standardized, Verified Potency
Independently standardized to 30% catechins and 50% EGCG per capsule, addressing a documented quality-control problem where some commercial green tea products contain far less catechin than their label claims.
Metabolism & Energy Expenditure
Green tea catechins have been studied for a modest thermogenic effect on energy expenditure and fat oxidation, beyond what their small caffeine content alone would explain.
Cardiovascular Health
Green tea extract rich in EGCG has been studied for effects on LDL cholesterol, blood pressure and other cardiovascular risk markers.
Healthy Body Weight
Systematic reviews describe a small effect of green tea catechins on body weight and fat mass - real, but modest, and not a substitute for diet and exercise.
Exercise Recovery
Catechin antioxidants have been studied for their effect on oxidative-stress markers and muscle-damage recovery after strenuous exercise.
Long-Term Wellness
Large Japanese population studies have linked regular green tea consumption with lower rates of cardiovascular mortality and stroke over many years.

What the research says about Green Tea Catechins & EGCG
Educational summaries of published research on green tea extract, catechins and EGCG; not product-specific claims. CanPrev Green Tea's own claim is the use authorized under NPN 80130629: a source of antioxidants that help protect against the oxidative damage caused by free radicals.
A classic review of how tea catechins act as antioxidants in the body
A widely cited review of tea catechin research found catechins and EGCG are effective scavengers of reactive oxygen species in vitro and may also act indirectly as antioxidants through effects on transcription factors and enzymes, though the authors noted human biomarker data on oxidative damage were still limited at the time and called for larger studies.
Review8 weeks raised plasma antioxidant capacity and glutathione in metabolic syndrome
In 35 obese adults with metabolic syndrome, 8 weeks of green tea beverage (4 cups/day) or green tea extract (2 capsules/day) significantly increased plasma antioxidant capacity and whole-blood glutathione compared to controls, with no change in catalase or glutathione peroxidase activity.
Human RCTAn honest null result: no added benefit in already well-nourished older adults
A 16-week trial in healthy adults aged 50-70 found that adding 200 mg/day of green tea extract to a lutein supplement significantly raised plasma lutein and carotenoid levels but produced no significant change in overall antioxidant status or lipid peroxidation markers versus lutein alone - a reminder that antioxidant supplementation shows the clearest effects when baseline levels are actually low.
Human RCTA landmark study: green tea extract raised 24-hour energy expenditure by 4%
In 10 healthy men, a green tea extract (50 mg caffeine plus 90 mg EGCG) significantly increased 24-hour energy expenditure by 4% and lowered the respiratory quotient (indicating more fat being burned) compared to placebo, while caffeine alone at a matching dose had no such effect - suggesting the catechins themselves, not just the caffeine, drive the effect.
Human RCT12 weeks of catechin-rich tea reduced body fat in healthy men
In a 12-week double-blind study, Japanese men who drank tea providing 690 mg of catechins daily showed significantly greater reductions in body weight, BMI, waist circumference and body fat than men drinking a low-catechin control tea (22 mg/day).
Human RCTAn honest null result: no significant acute effect at these catechin doses
In 15 healthy men measured in a metabolic chamber for over 13 hours, single doses of caffeine plus 600 mg of various catechin mixtures (including EGCG-enriched) produced no statistically significant change in energy expenditure or fat oxidation versus caffeine alone or placebo, though the authors noted the small numeric trend could still matter over much longer-term use.
Human RCTMeta-analysis: a small but real effect on weight loss and maintenance
Pooling 11 studies, a meta-analysis found green tea catechins produced a small but statistically significant effect on weight loss and on maintaining weight after loss, with ethnicity and habitual caffeine intake as possible moderators of the effect size.
Meta-analysisCochrane review: a small, non-significant weight-loss effect outside Japan
A Cochrane systematic review of green tea preparations for weight loss found a statistically non-significant mean weight difference of -0.04 kg in studies conducted outside Japan, concluding any weight-loss effect was small and unlikely to be clinically important, though only two of many studies reported adverse events requiring hospitalization (not attributed to the intervention).
Cochrane systematic reviewSystematic review: EGCG doses of 100-460 mg/day were most effective at 12+ weeks
A systematic review of 15 human studies found daily EGCG doses between 100 and 460 mg over intervention periods of 12 weeks or longer showed the greatest effectiveness for reducing body fat and body weight, with added caffeine (80-300 mg/day) an important contributing factor in participants without high habitual caffeine intake.
Systematic review3 months improved blood pressure, lipids and insulin resistance
In a double-blind, placebo-controlled trial of 56 obese, hypertensive adults, 3 months of a 379 mg green tea extract capsule significantly reduced systolic and diastolic blood pressure, fasting glucose and insulin resistance, lowered inflammatory markers (TNF-alpha, CRP) and improved LDL, HDL and triglyceride levels versus placebo.
Human RCTA large 12-month trial: EGCG-rich extract lowered LDL cholesterol
In a 12-month, double-blind, placebo-controlled trial of 1,075 postmenopausal women, daily green tea extract capsules providing 1,315 mg catechins (843 mg EGCG) significantly reduced total cholesterol and LDL cholesterol compared to placebo, with the largest effect in women with elevated baseline cholesterol.
Human RCT12 weeks of green tea powder lowered LDL cholesterol, but not body weight
In a randomized trial of 151 adults, 12 weeks of daily green tea extract powder (1.8 g/day) significantly lowered LDL cholesterol versus placebo regardless of tea variety, though neither tea had any significant effect on body weight - an honest reminder that a cardiovascular benefit doesn't always come with a weight-loss one.
Human RCTA landmark 40,530-person Japanese cohort: less cardiovascular mortality
The Ohsaki Cohort Study followed over 40,000 Japanese adults for up to 11 years and found those drinking 5 or more cups of green tea daily had significantly lower all-cause and cardiovascular mortality than those drinking under 1 cup/day, with no association found for cancer mortality.
Prospective cohort (n=40,530)82,369-person cohort: higher green tea intake linked to lower stroke risk
In the Japan Public Health Center-based cohort of over 82,000 adults followed for 13 years, those drinking 4 or more cups of green tea daily had a significantly lower risk of all strokes and cardiovascular disease compared to infrequent drinkers.
Prospective cohort (n=82,369)A 14,000-person study: green tea linked to lower risk of losing independence with age
In a 3-year prospective study of nearly 14,000 Japanese adults aged 65 and older, those drinking 5 or more cups of green tea daily had a 33% lower risk of developing a functional disability requiring long-term care than those drinking less than 1 cup/day.
Prospective cohort (n=13,988)800 mg/day of pure EGCG was safe and well tolerated over 10 days
A randomized, double-blind, placebo-controlled study of 36 healthy men found repeated daily doses of purified EGCG (up to 800 mg/day for 10 days) were rapidly absorbed, safe and well tolerated, with dose escalation above 400 mg showing more-than-proportional increases in blood levels - useful pharmacokinetic context for a standardized 250 mg EGCG daily dose.
Human RCTWhy standardization matters: commercial products varied wildly from their label claims
An independent HPLC analysis of 7 commercial green tea products found actual catechin content ranged from just 9% to 48% of what the label claimed, with every product testing significantly below its stated potency - illustrating why an independently standardized extract (guaranteeing a specific % of catechins and EGCG) is not just marketing language.
Analytical studyA mechanistic review of how EGCG and other catechins act at the cellular level
A review of dietary polyphenols including EGCG found they can reduce fat-cell viability, suppress fat-cell differentiation, stimulate fat breakdown and reduce inflammation in cell and animal studies by modulating pathways such as AMPK and PPAR-gamma, while noting that human trial results have been less consistent than the preclinical mechanisms would suggest.
Review6 weeks of green tea extract raised blood antioxidant capacity in trained men
In young men doing CrossFit training, 6 weeks of green tea extract supplementation significantly increased total antioxidant capacity (FRAP) at rest and after exercise compared to placebo, and moderately reduced exercise-induced lipid peroxidation, though it had only a marginal effect on aerobic capacity.
Human RCTGreen tea extract preserved neuromuscular function under cumulative fatigue
In a triple-blind, placebo-controlled trial, 15 days of green tea extract (500 mg/day) reduced muscle damage and oxidative stress markers and better preserved neuromuscular activation than placebo in athletes undergoing repeated fatiguing exercise sessions.
Human RCTMeta-analysis: lower muscle-damage markers, but antioxidant status was equivocal
A meta-analysis of 19 studies (416 participants) found tea-leaf extract supplementation significantly reduced indirect markers of exercise-induced muscle damage and oxidative stress at 24 hours post-exercise, but found no significant difference in overall antioxidant status between supplemented and placebo groups - an honest, mixed result.
Meta-analysisUSP systematic review: 216 case reports and the empty-stomach risk factor
A US Pharmacopeia systematic safety review of 216 case reports on green tea products (including 34 involving liver damage) found that consuming concentrated green tea extracts on an empty stomach was more likely to be associated with adverse liver effects than consumption with food - the basis for this product's own label directing adults to take it with food.
Systematic reviewA review of 34 published cases and the likely mechanism
A literature review identified 34 published cases of hepatitis linked to green tea products (plus 2 new Italian cases), with a positive dechallenge (improvement after stopping) in 29 cases; the authors proposed the hepatotoxicity is likely related to EGCG or its metabolites inducing oxidative stress in the liver under certain individual metabolic conditions.
Review + case reportsA 2023 genetic clue: an HLA gene variant linked to green-tea-extract liver injury
A case report of monozygotic twins who both developed jaundice after taking a green-tea-extract-containing weight-loss supplement found both twins carried the HLA-B*35:01 allele, a genetic variant previously identified as a risk factor for green tea extract-induced liver injury - a real, published example of why this reaction is described as rare and unpredictable rather than dose-dependent for everyone.
Case reportFrequently asked questions
How do I take CanPrev Green Tea?
Adults 18 years and older take 1 capsule per day with food, or as directed by a qualified health care practitioner. Consult a health care practitioner for use beyond 12 weeks.
What's in each capsule?
Each capsule contains 500 mg of green tea extract (leaf, Camellia sinensis) equivalent to 10,000 mg dried leaf, standardized to 30% catechins, 50% EGCG and 0.5% caffeine. Non-medicinal ingredients are hypromellose, magnesium stearate and microcrystalline cellulose.
Is this the same product as CanPrev Antioxidant Network?
No. This product (NPN 80130629) is a single-ingredient, standardized 500 mg green tea extract. CanPrev Antioxidant Network (NPN 80130770) is a different, separately licensed multi-ingredient product that includes a much smaller 60 mg dose of green tea extract alongside CoQ10, NAC, alpha lipoic acid, vitamin E, zinc and selenium. They share one overlapping ingredient but are distinct formulas with their own NPNs, doses and claims.
How much caffeine does this contain?
About 2.5 mg of caffeine per capsule (0.5% of the 500 mg extract) - roughly the caffeine content of a cup of decaffeinated coffee, far less than a cup of brewed green tea or coffee.
Is there a safety concern with green tea extract?
Yes - rare, unpredictable cases of liver injury associated with green tea extract-containing products have been reported in Canada and internationally. Consult a health care practitioner before use if you are pregnant, breastfeeding, have a liver disorder, or have an iron deficiency, and stop use and consult a health care practitioner if you develop symptoms of liver trouble such as yellowing of the skin/eyes (jaundice), stomach pain, dark urine, sweating, nausea, unusual tiredness and/or loss of appetite.
Why does the label say to take it with food?
Health Canada's safety review of green tea extract products found that consumption on an empty stomach is more likely to be associated with adverse liver effects than consumption with food, which is why this product's label directs adults to take it with food.
Is it vegan and allergen-friendly?
Yes - the capsules are vegan, non-GMO, gluten-free, dairy-free and soy-free, with no artificial colours, flavours or preservatives.
Is CanPrev Green Tea made in Canada?
Yes. It is formulated and made in Canada by CanPrev Natural Health Products Ltd. and licensed by Health Canada under NPN 80130629.
