Only hand-selected leaves from certified organic plantations in Sri Lanka are used, favouring young shoots naturally richer in active compounds. Extraction is water-only, like a traditional infusion, but via a controlled process reaching exceptional concentration — no chemical solvents, nanoparticles or additives, and no GMOs, gluten or dairy derivatives. The plant-based HPMC capsules complete this uncompromising approach.

The high polyphenol content, particularly EGCG (epigallocatechin gallate), gives these capsules remarkable antioxidant activity, helping limit cellular ageing linked to oxidative stress. EGCG supports lipid metabolism (thermogenesis) and studies also point to positive effects on cholesterol regulation and vascular elasticity, plus support for memory, focus, digestive comfort and blood sugar maintenance. Theine content stays moderate (under 30mg per capsule), avoiding excess stimulation.

Each 2-capsule serving provides 1,000mg of organic dry green tea extract, standardised to at least 90% polyphenols, including at least 24% catechins and 8% EGCG — among the highest titrations available in supplement form. Green tea’s antioxidants, notably EGCG, show a stronger free-radical scavenging power than vitamin C or E, with optimal absorption in concentrated encapsulated form.

Take 1 to 2 capsules a day, ideally in the morning or early afternoon, away from meals, with a large glass of water — this limits theine’s impact on sleep and maximises absorption.

Not recommended for pregnant or breastfeeding women, or for people treated for heart conditions. If sensitive to caffeine, start with the minimum dose of one capsule a day. Consult a healthcare professional if in doubt or combining with other supplements. Store away from heat and moisture.

How do I recognise a good green tea extract?

Look for a high polyphenol concentration (minimum 90%) with a stated EGCG content (at least 8%), aqueous extraction, no additives or GMOs, and organic certification with documented quality analysis.

When and how should I take these capsules?

Take 1 to 2 capsules a day away from meals, ideally morning or early afternoon, with plenty of water for good digestive tolerance.

Are there known contraindications?

Highly concentrated extracts may not be advisable during pregnancy or breastfeeding, or for those treated for heart conditions — consult a healthcare professional if in doubt.
