Tegreen 97® (120 count) (Canda)

Tegreen 97 is a concentrated green tea extract delivering 97% polyphenols per capsule — including a standardized dose of EGCG (epigallocatechin gallate), the catechin responsible for most of green tea's researched health benefits. Each capsule provides the antioxidant equivalent of approximately 7 cups of green tea, without the caffeine load (each capsule contains less than 9 mg caffeine vs ~95 mg in a cup of coffee). With over 10,000 published studies on green tea catechins and their role in antioxidant defence, metabolic support, and cellular protection, Tegreen 97 is one of Pharmanex's most research-backed products. The 120-count bottle provides a 60-day supply at standard dosing.

What Makes Tegreen 97 Different

You can buy green tea extract at any health food store in Canada. What you can't easily buy is a 97% polyphenol extract with guaranteed EGCG content verified through Nu Skin's 6S Quality Process. Most commercial green tea supplements range from 50–80% polyphenol content, with EGCG doses that vary wildly between batches because they're not standardized.

Tegreen 97 is also caffeine-controlled — each capsule contains less than 9 mg of caffeine. This matters because many green tea extracts deliver 50–100 mg caffeine per capsule, which limits when you can take them (not in the evening) and who can take them (not those sensitive to caffeine). Tegreen's low caffeine means you get the antioxidant benefits without the stimulant effects.

The extraction process preserves the catechin profile found in fresh tea leaves while removing the tannins that can cause stomach upset. If you've ever felt queasy drinking green tea on an empty stomach, that's the tannins — Tegreen's extraction process addresses this.

Key Ingredients

EGCG (Epigallocatechin Gallate): The most studied catechin in green tea. A systematic review in the European Journal of Clinical Nutrition (2014) analysed 17 randomized controlled trials and found that green tea catechins, particularly EGCG, supported modest but consistent metabolic benefits. EGCG's antioxidant capacity exceeds that of vitamins C and E on a per-molecule basis.

Total Polyphenols (97%): Including epicatechin (EC), epicatechin gallate (ECG), and epigallocatechin (EGC) in addition to EGCG. These catechins work synergistically — research suggests the combination is more effective than isolated EGCG alone.

Minimal Caffeine (<9 mg per capsule): Deliberately controlled to allow therapeutic dosing without stimulant effects. For comparison, a single espresso contains ~63 mg. Even taking 2 capsules daily delivers less caffeine than half a cup of regular coffee.

How to Use

Take 1–2 capsules daily with food. For general antioxidant support, 1 capsule daily is sufficient. For more targeted metabolic or antioxidant support, 2 capsules daily (morning and evening) is the standard dose.

Take with food — green tea catechins absorb better with a meal, and the small amount of remaining tannins is better tolerated on a full stomach. Avoid taking with dairy if possible — casein in milk can bind to catechins and reduce absorption. Almond milk, oat milk, or black coffee alongside your capsule is fine.

For Canadians, the antioxidant support is particularly relevant during winter months when dietary variety tends to decrease and antioxidant intake from fresh fruits and vegetables drops. Tegreen 97 maintains your antioxidant defence when your diet may not.

The low caffeine content means evening dosing is fine for most people. If you're extremely caffeine-sensitive, stick to morning dosing.

How It Compares

On a pure cost-per-capsule basis, Jamieson and NOW Foods are significantly cheaper. The difference is polyphenol purity (97% vs 50–80%) and batch-verified quality testing. If you want the highest-concentration green tea extract with guaranteed catechin content and minimal caffeine, Tegreen 97 is the premium option. If basic green tea extract at a budget price is sufficient for your needs, Jamieson works fine.

Who Is This For

If you're interested in daily antioxidant support but don't want to drink 7 cups of green tea (or deal with that much caffeine and tannin-related stomach issues), Tegreen 97 delivers the beneficial compounds in a single capsule.

If you're building a comprehensive supplement stack — LifePak for nutritional foundations, Marine Omega for essential fats — Tegreen 97 adds a concentrated antioxidant layer that complements those products without overlapping.

If you're a health-conscious Canadian professional who reads research and wants specific, standardized doses rather than vague "green tea blend" products, the 97% polyphenol standardization gives you confidence in what you're actually consuming.

Not ideal if you're sensitive to caffeine and consume it close to bedtime (though at <9 mg per capsule, this affects very few people). Not recommended for pregnant or nursing women without consulting a healthcare practitioner. If you take blood-thinning medication, check with your practitioner — catechins may interact with some anticoagulants.

Frequently Asked Questions

Q: How do I purchase Tegreen 97 in Canada?

Order from nubestskin.com — no membership or registration needed. Ships from the official Nu Skin Canada warehouse. Standard shipping: CA$2.99, free over CA$79. Delivery: 3–5 business days across Canada.

Q: Is Tegreen 97 basically just green tea in a capsule?

It's a concentrated extract — each capsule delivers the polyphenol equivalent of ~7 cups of green tea with less caffeine than a single sip of coffee. Brewing tea gives you a fraction of the catechins (hot water extracts maybe 30–40% of available polyphenols), while the 97% standardized extract captures nearly all of them.

Q: Can I take Tegreen 97 with LifePak?

Yes. LifePak contains some green tea catechins in its antioxidant blend, but at lower concentrations. Adding Tegreen 97 provides a concentrated dose that elevates your total catechin intake to therapeutic levels without any safety concerns from the combination.

Q: Will it keep me awake if I take it in the evening?

Unlikely — each capsule has less than 9 mg caffeine, which is about 1/10th of a cup of coffee. Most people have no sleep disruption at all. If you're extremely caffeine-sensitive, take both capsules in the morning.

Q: How long until I notice benefits?

Antioxidant effects occur at the cellular level from day one, but perceptible benefits (improved energy, better skin clarity) typically emerge at 4–6 weeks of consistent use. Blood markers of antioxidant status show changes at 8–12 weeks.

Works With

LifePak or LifePak Nano: LifePak's broad antioxidant blend provides the foundation; Tegreen 97 adds a concentrated catechin boost. Together, they deliver a comprehensive antioxidant defence covering multiple pathways.

ageLOC R² Day: The daytime energy formula benefits from Tegreen's metabolic support — catechins influence fat oxidation and thermogenesis, complementing R²'s mitochondrial energy focus.

Nu Biome: Emerging research suggests that green tea polyphenols have prebiotic effects, selectively supporting beneficial gut bacteria. Taking Tegreen alongside Nu Biome's prebiotic + postbiotic formula may enhance microbiome diversity.
