Tegreen 97 (Australia)

Tegreen 97® (AU$112.00) is Pharmanex's concentrated green tea catechin extract, standardised to 97% polyphenols with a high EGCG content (the catechin most studied for antioxidant activity). Each capsule delivers polyphenol density equivalent to roughly 7 cups of green tea but contains only ~4 mg of caffeine — about 92% less than the ~50 mg in a brewed cup — which makes it usable for adults already consuming coffee or who are caffeine-sensitive at higher doses. Designed for daily antioxidant defence and metabolic support. Ships from the official Nu Skin warehouse in Australia, no Nu Skin membership or registration required.

⚠️ Caffeine notice: Tegreen 97 contains approximately 4 mg of caffeine per capsule. A four-capsule daily dose delivers ~16 mg — roughly the caffeine in half a small cup of green tea. Adults extremely sensitive to caffeine, those who avoid all caffeine sources, and pregnant or breastfeeding women should consult their healthcare professional before use.

What Makes It Different

Most green tea supplements on the Australian market are not standardised to a specific polyphenol percentage — the label says "green tea extract" without disclosing how much active compound is actually in the capsule. Polyphenol and catechin content in raw green tea varies widely depending on cultivar, harvest timing, processing temperature, and storage conditions, so unstandardised extracts can deliver very different doses from batch to batch. Tegreen 97 is standardised to 97% polyphenols and a minimum catechin content, so each capsule delivers a consistent dose against which research-derived dosing recommendations can actually be applied.

The second differentiator is the caffeine reduction. A brewed cup of green tea contains around 30–50 mg of caffeine; Tegreen 97 contains approximately 4 mg per capsule — about 92% less than a single cup. For adults already drinking coffee daily, this means you can layer in the polyphenol load without stacking additional stimulants. According to Cabrera C, Artacho R, Giménez R in the Journal of the American College of Nutrition (2006;25(2):79–99), green tea catechins — particularly EGCG — demonstrate significant free-radical scavenging activity in human studies, and the catechin profile extracted via Pharmanex's process retains a broad spectrum rather than isolating EGCG alone.

Key Ingredients

EGCG (epigallocatechin gallate): The most abundant and most-researched catechin in green tea. Acts as a potent antioxidant by donating hydrogen atoms to neutralise reactive oxygen species. Subject of thousands of published studies examining cellular protection, metabolic, and immune-support endpoints. EGCG typically accounts for 50–80% of total catechin content in quality green tea extracts.

Polyphenols (97% standardised): Polyphenols are plant-based compounds that support the body's antioxidant defence systems. At 97% concentration, Tegreen delivers significantly higher polyphenol density per dose than drinking green tea — you would need 7+ cups daily to match a single capsule's polyphenol content. Polyphenols also support immune function indirectly through interaction with gut microbiota.

Broad-spectrum catechins: Beyond EGCG, Tegreen retains epicatechin (EC), epicatechin gallate (ECG), and epigallocatechin (EGC). Each has slightly different antioxidant mechanisms and tissue affinities, so the broad spectrum provides a more comprehensive cellular-protection profile than EGCG-isolate supplements. The catechin ratio mirrors the natural profile of high-quality green tea leaves.

Who Is This Designed For

✅ Best suited: Adults seeking concentrated antioxidant and metabolic support who want a standardised, dose-consistent extract — particularly those who already drink coffee daily and want polyphenol density without stacking extra caffeine, and Australians in high-UV regions (QLD, NT, northern WA) where year-round oxidative load is meaningful.

⚠️ Less suited: Consult your healthcare professional first if you are taking blood thinners (warfarin, apixaban), beta-blockers, statins, or chemotherapy; if you have liver disease or elevated liver enzymes; if you are extremely caffeine-sensitive; or if you are pregnant or breastfeeding (high-dose EGCG is not recommended during pregnancy). Take with food, not on an empty stomach.

💡 Pairs well with: a daily multivitamin foundation, regular moderate-intensity exercise, and adequate hydration during Australian summer months.

Comparison information based on publicly available product specifications as of May 2026. Pharmacy product formulations vary across reformulations.

The category-level point: green tea extract supplementation is most useful when the dose and catechin profile per capsule are known and consistent. Pharmacy-aisle green tea capsules deliver real but variable doses; standardising to 97% polyphenols means the daily catechin load matches what the published research used. If your priority is a low-cost daily green tea supplement for general antioxidant exposure, mainstream pharmacy options are reasonable for that simpler goal. For users who want dose-consistent polyphenol supplementation alongside other Pharmanex products, Tegreen 97 is built around standardised, stable batch-to-batch potency.

How Australians Are Using It

The recommended adult dose is 1–4 capsules daily, taken with food. Most users start at 1 capsule with breakfast and titrate up gradually based on tolerance. Because the caffeine content is minimal (~4 mg per capsule, ~16 mg at the four-capsule daily dose), it does not typically interfere with sleep even at afternoon timing — though caffeine-sensitive users should keep dosing to morning and midday only.

What to expect: antioxidant supplementation works at the cellular level rather than producing acute subjective effects. The first 1–2 weeks establish the routine without notable subjective change. Across weeks 4–8 of consistent daily use, users tracking biomarkers or skin condition often report changes; the most reliable subjective marker for users on the higher end of the dose range is recovery quality after exercise or sun exposure. Individual results vary based on baseline diet, antioxidant status, and concurrent lifestyle factors.

Australian context: in Queensland, Northern Territory, and northern WA where UV exposure is high year-round, daily polyphenol support is structurally relevant — UV-induced oxidative stress accumulates regardless of season and is one of the largest sources of cellular oxidative load in tropical and sub-tropical climates. Take with food (especially the larger 3–4 capsule doses) to minimise the small risk of digestive upset that can occur with concentrated catechin extracts on an empty stomach.

Works With

LifePak® Premium Multivitamin

The daily nutritional foundation that Tegreen 97 sits on top of. LifePak supplies the broad vitamin, chelated mineral, and full-spectrum carotenoid base; Tegreen 97 adds concentrated catechin polyphenol density on top. The combination covers more antioxidant pathways than either alone — fat-soluble carotenoids in LifePak, water-soluble polyphenols in Tegreen 97.

ReishiMax GLp®

For users heading into the May–September Australian winter, Tegreen 97 (general antioxidant + metabolic support) layers cleanly with ReishiMax GLp (immunomodulatory). Take Tegreen 97 in the morning with breakfast and split ReishiMax GLp across morning and evening doses; the two work through different mechanisms and don't compete for absorption.

Frequently Asked Questions

Can I buy Tegreen 97 in Australia without signing up to Nu Skin?

Yes. NuBest Skin sells Tegreen 97 at AU$112.00 with no Nu Skin membership, no registration, and no minimum order. Free shipping applies on orders over AU$99 and the product ships from the official Nu Skin warehouse in Australia within 3–5 business days.

Is Tegreen 97 caffeine-free?

No, but the caffeine content is low. Each capsule contains approximately 4 mg of caffeine — about 92% less than a brewed cup of green tea (~50 mg) and roughly 96% less than a cup of brewed coffee (~100 mg). At the four-capsule daily dose, total caffeine is ~16 mg — under the dose typical of decaf coffee. Most caffeine-sensitive individuals tolerate it well, but if you avoid all caffeine sources or are extremely sensitive, consult your healthcare professional first.

How is Tegreen 97 different from regular pharmacy green tea capsules?

The defining differences are standardisation and polyphenol density. Tegreen 97 is standardised to 97% polyphenols, so the polyphenol load per capsule is consistent batch-to-batch and matches research-derived dosing ranges. Most pharmacy green tea supplements specify the extract weight without disclosing the polyphenol percentage, so the actual catechin content can vary substantially. Tegreen 97 also retains a broad-spectrum catechin profile (EGCG plus EC, ECG, and EGC) rather than isolating EGCG alone.

Can I take it with prescription medication?

Consult your GP or pharmacist before starting if you take prescription medication. Specific interactions to flag: blood thinners (warfarin, apixaban) — high-dose green tea catechins may have mild anticoagulant activity; beta-blockers — green tea catechins can affect absorption of nadolol; statins — high-dose EGCG may interact with hepatic metabolism; chemotherapy — discuss with your oncologist before adding any high-polyphenol supplement.

Is it safe during pregnancy or breastfeeding?

No, not without practitioner sign-off. High-dose EGCG supplementation is not recommended during pregnancy due to potential interaction with folate metabolism, and safety data for breastfeeding is insufficient to recommend without specific medical advice. Drinking moderate green tea during pregnancy is different from concentrated EGCG capsule supplementation; the dose levels are not equivalent.

Will it help with weight loss?

Tegreen 97 is not formulated or marketed as a weight-loss product. Green tea catechins have been studied for thermogenic and metabolic-support endpoints, but the effect sizes in published research are modest and depend heavily on dietary and lifestyle context. Tegreen 97 supports general antioxidant defence and cellular protection; users seeking targeted weight management should look at Nu Skin's TRMe range, which is specifically designed for that goal.

Can I take it on an empty stomach?

Take with food. Concentrated catechin extracts on an empty stomach can occasionally cause mild digestive upset (nausea, gastric discomfort) in sensitive individuals, particularly at the higher end of the dose range. Taking with breakfast and dinner — rather than between meals — is the standard recommendation.

How should I store it?

Store in a cool, dry place below 25°C, away from direct sunlight. Polyphenols are sensitive to heat and oxidation; extended exposure above 30°C — common in Brisbane, Perth, NT, and northern NSW summers without air-conditioning — can degrade catechin content over time. The capsule format protects the contents better than loose tea, but room-temperature storage in an airtight bottle is still important.

Important Information

Always read the label and follow the directions for use. Vitamin and mineral supplements should not replace a balanced diet. If symptoms persist, consult your healthcare professional. Not suitable for children under 15 years unless advised by a healthcare practitioner. If pregnant, breastfeeding, taking prescription medication, with liver disease, or extremely caffeine-sensitive, consult your GP before use.
