Tegreen 97® (120 Capsules) (Singapore)

The Concentrated Green Tea Supplement Built for Singapore's Daily Antioxidant Demands

You already drink kopi in the morning, teh at the hawker centre, and maybe a latte at your Orchard Road café meeting. Adding seven cups of green tea on top — the amount you'd need to match a single Tegreen 97® capsule's catechin content — isn't realistic, and would push your caffeine intake well past a sensible daily limit. Tegreen 97® solves this precisely: each capsule delivers 250mg of catechins standardised to 97% polyphenols, with 99.5% of caffeine removed. Year-round UV index 11–12, daily commutes between 33°C humidity and aggressive air-conditioning, and constant environmental particulate exposure during haze season all place continuous oxidative stress on your body. Tegreen 97® is designed for consistent, daily antioxidant defence — without the caffeine load that would disrupt your sleep or stack on top of an already-caffeinated day.

⚠️ Caffeine notice: Tegreen 97® contains approximately 0.5% residual caffeine — less than 2mg per capsule. At 1–2 capsules daily, this is negligible for most adults. However, pregnant or breastfeeding women and individuals with caffeine sensitivity should consult a healthcare professional before use. 📋 HSA Note: Tegreen 97® is classified as a health supplement under Singapore's Health Sciences Authority (HSA) Health Supplements Guidelines. It is not a medicine and is not intended to diagnose, treat, cure, or prevent any disease.

What Makes Tegreen 97® Different

The "97" in the name is a specification, not a marketing label. It refers to the 97% polyphenol standardisation of each capsule — a concentration level that most green tea supplements available at Guardian or Watsons Singapore do not come close to. Standard green tea extracts on pharmacy shelves are typically standardised to 50–60% polyphenols. To match the catechin content of a single Tegreen 97® capsule, you would need to take three to four capsules of most competing products.

Each capsule delivers 250mg of catechins. That is roughly equivalent to the catechin content of seven cups of brewed green tea — but with 99.5% of the caffeine removed. The residual caffeine amounts to less than 2mg per capsule, compared to 30–50mg in a typical cup of green tea. For Singaporeans balancing kopi-O, teh tarik, and office-floor coffee throughout the day, this decoupling of catechins from caffeine is practically significant.

Catechin content is verified per batch using HPLC (high-performance liquid chromatography), ensuring that what is stated on the label is what is in each capsule. Batch-to-batch variation is a documented issue across the broader supplement industry; pharmaceutical-grade standardisation at this level is not universal. A study by Pharmanex researchers published in the Journal of Medicinal Food confirmed measurable increases in plasma antioxidant capacity following Tegreen 97® supplementation, with catechins detectable in blood samples — confirming bioavailability of the concentrated extract form.

Key Ingredients

EGCG (Epigallocatechin Gallate)

The most studied catechin in green tea, with over 6,000 published studies indexed in PubMed. EGCG's studied mechanisms include inhibition of catechol-O-methyltransferase (COMT), an enzyme involved in fat metabolism, and activation of AMPK (AMP-activated protein kinase), which plays a role in cellular energy regulation. A 2009 meta-analysis in the International Journal of Obesity reviewing 11 studies found that green tea catechins increased energy expenditure by approximately 4.7% — with the effect more pronounced in Asian populations than Caucasian ones, which is directly relevant for Singapore's predominantly Asian demographic.

Full Catechin Spectrum (ECG, EGC, EC)

Tegreen 97® retains the complete spectrum of green tea catechins rather than isolating EGCG alone. Epicatechin (EC) has been studied for cardiovascular effects — a 2012 paper in the British Journal of Clinical Pharmacology reported improvements in endothelial function and nitric oxide availability. Epigallocatechin (EGC) contributes additional antioxidant capacity. Full-spectrum catechin retention allows for potential synergistic effects across the profile.

97% Polyphenol Matrix

The standardisation to 97% polyphenols, verified by HPLC per batch, ensures precise and consistent dosing. This is the core technical differentiator between Tegreen 97® and standard green tea extract capsules available at mass-market retailers. The extraction and concentration process simultaneously removes virtually all caffeine while preserving the catechin profile intact.

How to Use

Take 1–2 capsules daily, preferably between meals. EGCG absorption is better on an empty stomach — research published in the European Journal of Clinical Pharmacology found that food reduced EGCG bioavailability. Taking with a full glass of water is recommended. Given the virtually negligible caffeine content, timing flexibility is high — morning or midday dosing is suitable for most users.

Frequently Asked Questions

How long does delivery take to my Singapore address?

Tegreen 97® ships from Nu Skin Singapore island-wide, typically arriving within 1–3 business days. This covers all areas including Jurong, Tampines, Woodlands, Changi, and the CBD. No import delays apply as stock is held locally in Singapore.

Why is Tegreen 97® so much more expensive than green tea extracts at Guardian or Watsons?

The price difference reflects concentration, not just brand. Most green tea extracts at pharmacy chains are standardised to 50–60% polyphenols. Tegreen 97® is standardised to 97% — meaning you would need three to four capsules of a typical mass-market product to match the catechin content of a single Tegreen 97® capsule. The HPLC-verified, pharmaceutical-grade batch testing and published bioavailability research also contribute to the cost. At S$895 for a 10-pack (120 capsules per pack), the per-day cost across the full pack is approximately S$7.46.

How should I store Tegreen 97® in Singapore's humidity?

Store in a cool, dry location away from direct sunlight. Singapore's year-round ambient humidity of 80–90% RH can degrade supplement quality if capsules are left exposed. Keep the bottle tightly sealed after each use. Avoid storing near the bathroom or kitchen where steam accelerates moisture ingress. A bedroom drawer or dedicated supplement shelf in an air-conditioned room is ideal. Do not refrigerate unless the packaging specifically instructs it — condensation from refrigerator cycling can introduce moisture.

Can I take Tegreen 97® alongside my daily kopi or teh?

Yes. With less than 2mg of residual caffeine per capsule, Tegreen 97® adds negligibly to your total daily caffeine intake regardless of how many cups of kopi, teh, or coffee you already consume. This is precisely why the near-complete decaffeination is significant for Singapore users — you receive the catechin benefits without compounding your existing caffeine load.

Is Tegreen 97® registered with HSA Singapore?

Tegreen 97® is regulated as a health supplement under Singapore's Health Sciences Authority (HSA) Health Supplements Guidelines. Health supplements in Singapore are not required to undergo pre-market approval by HSA but must comply with compositional safety and labelling requirements. It is not classified as a medicine and does not carry medicinal claims. If you have questions about a specific health condition, consult a licensed healthcare professional in Singapore.

When is the best time to take Tegreen 97® capsules?

Between meals, with a full glass of water. Research published in the European Journal of Clinical Pharmacology indicates that EGCG bioavailability is reduced when taken with food. Morning or midday dosing between meals is practical for most Singapore daily schedules — before your lunch break or mid-morning, between breakfast and a hawker centre lunch, for example. Given the minimal caffeine content, there is no particular need to avoid evening dosing if that fits your routine better.

Does the capsule packaging hold up in Singapore's tropical climate?

The capsules are sealed in a standard supplement bottle designed to limit moisture exposure. In Singapore's high-humidity environment (80–90% RH year-round), ensure the cap is sealed firmly after each use. Products stored in HDB flat bathrooms or near kitchen areas with steam exposure may experience faster quality degradation than those stored in climate-controlled spaces. A dedicated, dry shelf in an air-conditioned room extends shelf stability.

Can I take Tegreen 97® with other Nu Skin supplements?

Tegreen 97® is formulated to complement other Nu Skin antioxidant and wellness supplements. Common combinations include pairing with LifePak® for a broader antioxidant and micronutrient base, or with Marine Omega for cardiovascular and anti-inflammatory support. If you are taking prescription medications or have existing health conditions, consult a Singapore-registered doctor or pharmacist before combining supplements.
