Tegreen 97® (120 count) (USA)

Tegreen 97® — The Most Concentrated Green Tea Antioxidant Available

You'd need to drink 7-10 cups of green tea daily to match the polyphenol content in four Tegreen 97 capsules. At 97% polyphenol concentration, this is the most potent green tea extract commercially available — delivering a clinical dose of EGCG and other catechins that research has linked to immune support, cellular protection, metabolic health, and antioxidant defense against environmental stressors.

Green tea catechins, particularly epigallocatechin gallate (EGCG), are among the most extensively studied plant compounds in nutrition science. Over 10,000 published studies have examined their effects on human health. The evidence for their antioxidant and cellular protective properties is robust enough that green tea extract is one of the few supplements that even skeptical researchers tend to regard favorably. Tegreen 97 makes therapeutic doses accessible without requiring you to drink green tea all day.

Key Benefits

• 97% Polyphenol Concentration — The highest catechin concentration commercially available in a green tea supplement. Each capsule delivers a standardized, potent dose of protective polyphenols
• Immune System Support — EGCG and other catechins support immune cell function by protecting immune cells from oxidative damage and supporting healthy immune signaling pathways
• Cellular Antioxidant Defense — Acts as a first line of defense against oxidative stress from pollution, UV exposure, blue light, stress hormones, and normal metabolic byproducts
• Metabolic Support — Green tea catechins support healthy thermogenesis and fat oxidation. Multiple meta-analyses confirm a modest but statistically significant effect on metabolic rate
• Low Caffeine — Each capsule contains approximately the caffeine of a few sips of tea — enough to enhance catechin absorption but not enough to cause jitters or sleep disruption

Key Ingredients

Tegreen 97's formula is elegantly simple: it's concentrated green tea leaf extract standardized to the highest commercially achievable polyphenol level. The complexity is in the concentration and standardization process.

• Green Tea Leaf Extract (97% Polyphenols) — Standardized to contain 97% total polyphenol content, with EGCG as the primary active catechin. EGCG is the largest and most studied catechin in green tea, accounting for approximately 50-80% of the total catechin content in quality extracts. Research published in the European Journal of Clinical Nutrition shows that EGCG's antioxidant capacity is approximately 25-100 times more potent than vitamins C and E on a per-molecule basis
• EGCG (Epigallocatechin Gallate) — The compound responsible for most of green tea's researched health benefits. EGCG is a potent free radical scavenger that also supports cellular signaling pathways involved in immune regulation, metabolic health, and cellular protection. Unlike many antioxidants, EGCG has demonstrated activity in both in-vitro and in-vivo human studies at achievable dietary doses
• Epicatechin, Epigallocatechin, Epicatechin Gallate — Additional catechins present in the extract that complement EGCG's activity. Research suggests that the full catechin spectrum works more effectively than isolated EGCG alone, supporting the whole-extract approach used in Tegreen 97

How Nu Skin's Approach Differs

Most green tea supplements on the market contain 50-80% polyphenols. Getting to 97% requires a more sophisticated extraction and concentration process that preserves the full catechin spectrum while removing non-active plant material. Pharmanex achieves this through proprietary processing that maintains the natural ratio of catechins found in fresh green tea leaves — EGCG dominant, with supporting catechins intact.

The standardization at 97% is meaningful because it ensures dose consistency. A capsule of unstandardized green tea extract might contain anywhere from 20% to 70% polyphenols depending on the tea source, harvest timing, and processing method. With Tegreen 97, every capsule delivers the same verified polyphenol content — allowing you to take a predictable, replicable dose.

Manufactured under the 6S Quality Process, each batch of Tegreen 97 is tested for catechin content, heavy metals, pesticide residues, and microbial contamination. Given that tea plants can accumulate heavy metals from soil, this testing provides meaningful quality assurance beyond what non-tested green tea supplements offer.

How It Compares

Comparison based on publicly available product information as of 2025. Features and formulations may change.

How to Use

Take 4 capsules daily — 2 in the morning and 2 in the afternoon, with or without food. This schedule provides antioxidant coverage across the entire day rather than a single spike. The 120-capsule bottle provides a 30-day supply at the recommended dose. If you're caffeine-sensitive, take all four capsules with meals (food slows caffeine absorption) and avoid the afternoon dose after 3pm.

Who Should Consider This Product

Tegreen 97 is relevant for anyone who wants concentrated antioxidant protection without the volume of liquid required from drinking green tea. It's particularly valuable for people with high environmental exposure (urban living, air pollution, frequent sun exposure), those looking for metabolic support alongside antioxidant defense, and anyone building a comprehensive supplement stack — Tegreen is included in the Well Being Kit alongside LifePak Nano and ageLOC Meta for good reason. If you're extremely caffeine-sensitive, the small amount per capsule usually isn't problematic, but the decaffeinated Life Extension option may be worth considering as an alternative.

Frequently Asked Questions

Q: How much caffeine is in each capsule?

A: Each capsule contains approximately 4-5mg of naturally occurring caffeine — roughly the amount in a single sip of green tea. Even at the full daily dose of 4 capsules (16-20mg total), this is far less than a single cup of coffee (~95mg). Most caffeine-sensitive individuals tolerate Tegreen without issues.

Q: Why not just drink green tea?

A: You'd need 7-10 cups daily to match 4 capsules of Tegreen 97. That's a lot of liquid, variable catechin content per cup (depending on brewing time, water temperature, and tea quality), and significantly more caffeine (~200-400mg vs. ~16-20mg). The extract provides concentrated, standardized benefits without the volume.

Q: Can I take Tegreen with LifePak?

A: Yes — they're designed as complementary products. LifePak provides comprehensive daily nutrition. Tegreen provides concentrated antioxidant defense from green tea polyphenols. They address different nutritional needs and are commonly used together. Both are included in the Nu Skin Well Being Kit.

Q: Are there any side effects?

A: Green tea extract is generally well-tolerated. In rare cases, concentrated green tea extract has been associated with liver concerns — these cases typically involved much higher doses than recommended and products with less rigorous quality testing. Follow the recommended dose, don't exceed 4 capsules daily, and discontinue if you experience unusual symptoms. If you have liver concerns, consult your healthcare provider.

Q: Does green tea extract interact with medications?

A: Green tea catechins can interact with certain medications. They may reduce the absorption of iron supplements and some medications including nadolol (a beta-blocker) and certain blood thinners. If you're on prescription medications, discuss green tea supplementation with your doctor or pharmacist.
