Tegreen 97® (120 Capsules) (New Zealand)

Tegreen 97 is a concentrated green tea extract standardised to 97% polyphenols, including a high proportion of catechins and EGCG (epigallocatechin gallate) — the most researched bioactive compound in green tea. Each capsule delivers the polyphenol equivalent of approximately seven cups of green tea without the caffeine load. At 120 capsules per bottle and a recommended dose of 1-4 capsules daily, it provides antioxidant, metabolic, and cellular health support that's backed by one of the deepest research bases of any natural compound.

What Makes Tegreen 97 Different

Green tea extract supplements are common, but standardisation varies enormously. Many products are standardised to 50-60% polyphenols, with the rest being non-active compounds. Tegreen 97's 97% polyphenol standardisation means you're getting a concentrated, consistent dose of the active compounds that clinical research has actually studied.

The EGCG content is particularly important. EGCG is the catechin with the most clinical evidence — it's been studied for antioxidant capacity, metabolic support, thermogenesis, and cellular health protection. A 2018 meta-analysis in Molecules (doi:10.3390/molecules23102801) reviewed 31 randomised controlled trials and confirmed that green tea catechins significantly reduced body weight, BMI, and waist circumference.

Critically, Tegreen 97 is largely decaffeinated — each capsule contains only about 9mg of caffeine (compared to 95mg in a cup of coffee). This means you can take therapeutic doses of green tea polyphenols without the jitters, sleep disruption, or adrenal stress that drinking seven cups of green tea daily would cause.

For New Zealanders, the antioxidant benefits are particularly relevant. NZ's intense UV environment generates significant free radical damage in skin and other tissues. Oral antioxidant supplementation provides systemic protection that topical sunscreen can't fully replicate — it works from the inside to support your body's defence against oxidative stress.

Key Ingredients

EGCG (epigallocatechin gallate): The star catechin. Research in The American Journal of Clinical Nutrition (2005;81(1):122-129) demonstrated that green tea catechins with caffeine increased energy expenditure and fat oxidation. EGCG activates thermogenesis through the noradrenaline pathway and supports AMPK activation — the same "metabolic switch" enzyme that exercise triggers.

Catechins (ECG, EC, EGC): Supporting catechins that provide additional antioxidant capacity and work synergistically with EGCG. The combined catechin profile of green tea is more effective than EGCG alone, which is why a standardised whole-extract approach works better than isolated EGCG supplements.

Polyphenols (97% standardised): Beyond catechins, the polyphenol profile includes flavonols and phenolic acids that support vascular health, gut microbiome diversity, and cellular signalling pathways involved in healthy ageing.

How to Use

Take 1-4 capsules daily with meals. Starting with one capsule and increasing gradually over a week allows your body to adjust. The flexible dosing means you can tailor intake to your goals: one capsule daily for general antioxidant support, two for metabolic support, or four for the full therapeutic dose used in most clinical studies.

For Kiwis using Tegreen 97 alongside an active lifestyle, taking a dose before exercise may enhance fat oxidation during workouts. A study in the International Journal of Sport Nutrition and Exercise Metabolism found that green tea catechins increased fat oxidation during moderate-intensity exercise by approximately 17%.

If you're sensitive to caffeine, stick to morning dosing or take it with food to slow absorption. At 9mg per capsule, even four capsules (36mg total) is less than half a cup of coffee, but individual caffeine sensitivity varies.

How It Compares

GO Healthy is widely available at a fraction of the price, but the polyphenol standardisation is significantly lower — you'd need to take more capsules to match Tegreen 97's catechin delivery. NOW Foods EGCg is a well-respected brand with high catechin content, though it focuses on isolated EGCG rather than the full catechin spectrum. Tegreen 97's advantage is the highest polyphenol standardisation on the market combined with a full-spectrum catechin profile.

Who Is This For

If you want potent antioxidant protection without drinking multiple cups of green tea daily, Tegreen 97 delivers the active compounds in concentrated form. It's particularly relevant for Kiwis whose UV exposure and outdoor lifestyle create significant oxidative stress.

If weight management is a goal, the metabolic support from EGCG — increased thermogenesis and fat oxidation — provides a modest but clinically documented edge. It won't replace diet and exercise, but it supports the metabolic processes that make those efforts more effective.

If you're interested in longevity and cellular health, EGCG's research profile is one of the most extensive in natural compounds. It's not a magic pill, but it's one of the most evidence-backed antioxidant interventions available.

This might not suit you if you're extremely caffeine-sensitive (though at 9mg/capsule, it's very low). If you're pregnant or nursing, consult your healthcare provider first. And if you're on blood-thinning medication, the catechins may interact — check with your GP.

Frequently Asked Questions

Q: How do I buy Tegreen 97 in New Zealand?

Order from nubestskin.com — no registration required. All orders ship from the official Nu Skin New Zealand warehouse. Standard shipping: NZ$4.99, free on orders over NZ$99. Typical delivery: 2-5 business days within New Zealand.

Q: Is Tegreen 97 the same as drinking green tea?

In terms of the active compounds, one capsule delivers roughly the polyphenol content of seven cups of green tea. The difference: you skip most of the caffeine, the volume of liquid, and the tannin taste. The polyphenol profile is concentrated and standardised for consistency — something brewed tea can't guarantee.

Q: Can I take it with LifePak?

Yes. LifePak contains some green tea catechins, but Tegreen 97 adds a concentrated dose for those wanting stronger antioxidant and metabolic support. There's no problematic overlap — the two are designed to complement each other.

Q: Will it help with weight loss?

Green tea catechins support metabolic rate and fat oxidation — documented in multiple clinical studies. The effect is modest (research suggests an additional 80-100 calories per day at therapeutic doses) but meaningful over time when combined with healthy eating and exercise. It's metabolic support, not a shortcut.

Q: How long does a bottle last?

At 120 capsules: 30 days at 4/day (full therapeutic dose), 60 days at 2/day (metabolic support), or 120 days at 1/day (general antioxidant). The flexible dosing makes it cost-effective to tailor to your needs.
