Tegreen 97® (120 count) (USA)

Tegreen 97 is a concentrated green tea extract delivering 97% polyphenols per capsule — one of the highest-concentration green tea supplements available in the US market. Each capsule provides the antioxidant equivalent of approximately 7 cups of green tea without the caffeine load (each capsule contains only about 9mg of naturally occurring caffeine, compared to ~50mg per cup of brewed green tea). At US$63.00 for 120 capsules (a 30-60 day supply depending on dosage), it's positioned as a premium antioxidant supplement for serious users, not a casual wellness add-on.

What Makes Tegreen 97 Different

Most green tea supplements on the US market deliver 50-70% polyphenol content with variable catechin profiles. Tegreen 97 is standardized to 97% polyphenols with a specific focus on EGCG (epigallocatechin gallate) — the catechin most studied for its antioxidant, thermogenic, and cellular protective properties. The standardization means you know exactly what you're getting per capsule, unlike generic "green tea extract" products where potency varies between batches.

A meta-analysis in the European Journal of Clinical Nutrition (2014, PMID: 24518747) confirmed that green tea catechins at concentrated doses provide measurable antioxidant protection, support cardiovascular health markers, and assist with thermogenesis. The EGCG content in Tegreen 97 also supports immune function — a 2011 study in the Journal of the American College of Nutrition found that concentrated green tea catechins reduced the incidence of cold and flu symptoms by 32.1% over 3 months.

Key Ingredients

Green tea catechins (97% polyphenols) — standardized extract rich in EGCG, EGC, ECG, and EC. EGCG is the most potent and most-studied catechin for antioxidant and thermogenic effects.

Minimal caffeine (~9mg per capsule) — naturally occurring caffeine that's substantially lower than brewed green tea (~50mg/cup) or coffee (~95mg/cup). Low enough that most caffeine-sensitive individuals can tolerate it.

How to Use

Take 2-4 capsules daily with meals. Start with 2 capsules daily and increase to 4 if well tolerated. Taking with food reduces the slight nausea that concentrated green tea extract can cause on an empty stomach. The low caffeine content (18-36mg total daily at 2-4 capsules) is unlikely to affect sleep even when taken in the afternoon, but caffeine-sensitive individuals should stick to morning doses.

Who Is This For

Ideal for: Anyone wanting concentrated antioxidant protection without consuming multiple cups of green tea daily. Particularly relevant for those focused on cellular protection, immune support, or metabolic health.

Also suited for: People who enjoy green tea's health benefits but can't tolerate the caffeine in 7+ cups daily — Tegreen 97 provides the polyphenols at a fraction of the caffeine.

Not recommended for: Anyone taking blood-thinning medications (green tea catechins can interact with anticoagulants). Consult your healthcare provider if on any medication.

Frequently Asked Questions

Can I buy Tegreen 97 in the US without signing up?
Yes. No membership needed. Ships from the official US warehouse.

Is this the same as drinking green tea?
Same beneficial compounds, concentrated. One Tegreen 97 capsule provides the catechin equivalent of approximately 7 cups of green tea, but with only ~9mg of caffeine instead of ~350mg you'd get from 7 cups. You get the antioxidant benefits without the excessive caffeine or liquid volume.

Can I take Tegreen 97 with LifePak?
Yes. LifePak includes a modest amount of green tea extract in its antioxidant complex, but Tegreen 97 provides a much higher concentrated dose. There's no safety concern with combining them — they complement each other.
