Patented, clinically proven water-soluble technology for weight loss and immune boosting
Why is Korean Green Tea Extract so special?
This is not your average green tea capsule or extract! The Korean Green Tea Extract - Extra Absorption 30pcs Stick is made with patented technology developed by the Korea Research Institute of Bioscience and Biotechnology (KRIBB), which can make green tea catechins and curcumin up to 400-1000 times more absorbable than conventional alternatives. The stick format microbeads can support fast and efficient absorption, allowing the premium active ingredients to be maximally utilized by the body.
While cheaper green tea capsules available in stores, such as those widely available in drugstores, often deliver minimal active ingredients to the body due to poor absorption, Korean Green Tea Extract can offer superior efficacy through TSP (Tencumin Solubilization Process) technology. KRIBB's research and patents can guarantee that this product goes far beyond simple green tea extracts.
- Scientific innovation.
- Clinical Background.
- Premium choice: The best green tea extract for those who want real results.
Did you know? Our Korean Green Tea Extract and Korean Turmeric Tablets (click!) were developed by the same South Korean research institute (KRIBB). The two products use the same patented water-soluble technology, so they can be combined together to support weight loss, metabolism and immune system.
What is catechin and why is it important?
Catechin is a 100% plant-based active ingredient extracted from green tea extract.
It hasa triple action: it can help reduce body fat, improve cholesterol and provide antioxidant protection for cells.

How does the technology work?
In their natural form, green tea catechins and curcumin are difficult to dissolve in water, so the active ingredients in traditional green tea capsules or extracts can only be partially utilized. Korean Green Tea Extract is designed to solve this problem with TSP technology , which has been perfected by KRIBB:
- Water solubility: natural solvents (e.g. liquorice-derived saponins) and proprietary equipment can convert the active ingredients.
- Absorption advantage: Tencumin G+ and CatecuMin S Plus technology have been clinically tested to provide up to 400-1000 times better bioavailability.
- Longer effect: active ingredients can be absorbed faster and remain active in the bloodstream for longer.

Support weight loss - Burning fat with science
The combination of green tea catechin and curcumin may support weight loss, as shown in clinical studies:
- Metabolic boosting: catechin may increase energy expenditure through its thermogenic effect, thus supporting fat loss.
- Body fat reduction: a 10-week study found that the group using TSP technology showed 41% less weight gain on a high-fat diet, suggesting that catechins may help inhibit fat deposition.
- Appetite control.
- Cholesterol improvement: may help maintain healthy blood fat levels, which may improve cardiovascular health.
The chart above shows that Group C, which consumed TSP, showed significantly less weight gain than the control group on a high-fat diet only. This means that the active ingredients in Korean Green Tea Extract have been scientifically proven to reduce weight gain even on a high fat diet!
Scientific background:
- Source: Nagao, T., & Tokimitsu (2007) A green tea extract high in catechins reduces body fat and cardiovascular risks in humans. Obesity, 15(6), 1473-1483.
- The study found that 300 mg of catechin intake per day can support body fat reduction, and Korean green tea extract exceeds this dose (1000 mg CatecuMin S Plus) with better absorption.
🛡️Immune system support - Protection at a premium level
Korean Green Tea Extract can also help support the immune system:
- Immune cell activation: a clinical study has shown that Tencumin G+ technology can increase the number of NK cells (Natural Killer) and CD4+/CD8+ T cells (immune system soldiers) by 40% in an immunosuppressed model (immune system in a weakened or suppressed state), which may help protect against infections.
- Antioxidant effect.
- Anti-inflammatory: Curcumin and catechin together can reduce inflammation, which can be particularly useful during diets.
- Antiviral and detoxifying properties.
Scientific background:
- Source: International Journal of Immunopharmacology, February 2023.
- The study tested the effect of an immunosuppressive agent (Cyclophosphamide) and TSP technology showed significant immune cell recovery, which may support the immune system.
Ingredients - Premium quality in every microbead
Korean Green Tea Extract consists of carefully selected, scientifically optimized ingredients:
- Catecumin S Plus (1000 mg): a water-soluble green tea catechin that may protect cells through antioxidant activity and support metabolism with its fat-burning properties.
