Pharmanex Tegreen (120 Capsules) (UK)

Pharmanex Tegreen delivers a concentrated dose of green tea polyphenols — standardised to 97% purity per capsule — with roughly 4mg of caffeine, a fraction of what you'd get from a standard cup of tea (~50mg) or coffee (~95mg). At £75.90 for 120 capsules (a 60-day supply at recommended dosage), it provides the antioxidant and metabolic benefits of green tea catechins without the caffeine load. The key compound is EGCG (epigallocatechin gallate), which is among the most studied natural polyphenols in nutritional science, with over 10,000 published studies on PubMed covering antioxidant activity, thermogenesis, immune support, and cellular protection.

What Makes Tegreen Different

You could drink green tea — but you'd need roughly 7-8 cups daily to match the catechin content in 2 Tegreen capsules, along with 350-400mg of caffeine. Tegreen uses a proprietary extraction and decaffeination process that retains the polyphenol profile while removing over 99% of the caffeine. The 97% polyphenol purity is significantly higher than most green tea extracts on the market — many standardise to only 40-60% polyphenols.

A meta-analysis in the International Journal of Obesity (Hursel R, et al., 2009;33(9):956-961, PMID: 19597519) found that green tea catechins produced modest but statistically significant increases in energy expenditure and fat oxidation. Separate research has established EGCG's role in supporting immune function through NK (natural killer) cell activity modulation — a 2011 study in the BMC Complementary and Alternative Medicine demonstrated enhanced immune response markers in participants taking green tea catechin supplements.

Key Ingredients

EGCG (Epigallocatechin Gallate) — The primary active catechin in green tea, EGCG is a potent antioxidant that neutralises free radicals and supports cellular protection. It also has documented thermogenic properties — supporting calorie expenditure through fat oxidation — at doses above 200mg daily.

Green Tea Polyphenols (97% purity) — The full spectrum of catechins includes EGCG, ECG, EGC, and EC. These compounds work synergistically, providing broader antioxidant coverage than EGCG alone. The 97% purity is Pharmanex's proprietary specification, verified through their 6S Quality Process.

Minimal Caffeine (~4mg per capsule) — Genuinely decaffeinated, not just "low-caffeine." For comparison, a standard cup of green tea contains 25-50mg caffeine and a cup of coffee contains 80-120mg. Two Tegreen capsules deliver roughly 8mg total — less than a single bite of dark chocolate.

How to Use

Take 1-2 capsules twice daily with meals. The 120-capsule bottle lasts approximately 60 days at 2 capsules per day. The low caffeine content means it's suitable for evening use without affecting sleep — something that can't be said for most green tea supplements, which retain significant caffeine. Pairs well with LifePak+ (complementary antioxidant mechanisms) and R² (additive antioxidant support through different pathways). During the British winter, when fresh fruit and vegetable intake often drops and antioxidant consumption declines, Tegreen provides consistent polyphenol support regardless of seasonal dietary changes.

Who Is This For

Anyone who wants the studied benefits of green tea catechins (antioxidant protection, metabolic support, immune function) without drinking 7+ cups of tea daily or consuming the associated caffeine. Particularly suited for caffeine-sensitive individuals, evening supplement users, and people who already consume moderate caffeine and don't want to add more. Also relevant for health-conscious adults who want evidence-backed antioxidant supplementation beyond basic vitamin C and E.

Frequently Asked Questions

Can I buy Tegreen without signing up?
Yes. NuBest Skin sells it directly — no membership, no account needed. Ships from the official Nu Skin UK warehouse.

Why not just drink green tea?
You'd need 7-8 cups daily to match the catechin dose in 2 Tegreen capsules, along with 350-400mg of caffeine. If you enjoy green tea, keep drinking it — but Tegreen provides therapeutic-level catechins with minimal caffeine, which tea alone cannot.

Will it keep me awake if I take it in the evening?
At roughly 4mg caffeine per capsule (8mg for a 2-capsule dose), it's extremely unlikely. For comparison, a cup of decaffeinated tea contains 2-5mg caffeine. Most people won't notice any stimulant effect.

Important Information

Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Do not exceed the recommended daily intake. Keep out of reach of young children. Store in a cool, dry place.
