Teavigo® – High-Purity EGCg Green Tea Extract for Advanced Nutritional Applications

What is Teavigo®?

Teavigo® is a high-potency green tea extract standardized for exceptionally high levels of Epigallocatechin-3-Gallate (EGCg), the major catechin naturally occurring in green tea. Produced from carefully selected Camellia sinensis tea leaves, Teavigo® is designed for dietary supplements, functional foods, beverages, and advanced nutritional formulations requiring highly concentrated green tea polyphenols.

Manufactured under strict Japanese quality standards, Teavigo® combines high purity, controlled sourcing, and carefully managed extraction technology to deliver a premium-grade green tea extract with excellent quality assurance and traceability.

What is EGCg?

Epigallocatechin-3-Gallate (EGCg) is the most abundant and biologically studied catechin in green tea. It is considered one of the primary contributors to the physiological and antioxidant properties associated with green tea consumption.

Catechins such as EGCg are powerful polyphenolic compounds that have been extensively investigated in animal and human studies for their role in protecting cells from oxidative stress and supporting metabolic and cardiovascular health.

Functional Areas of Interest for EGCg

Scientific studies have explored EGCg in a wide range of nutritional and physiological applications.

Areas Commonly Associated with Green Tea Catechins

Antioxidant protection
Cellular oxidative stress support
Metabolic support
Fat oxidation support
Weight management applications
Cardiovascular wellness support
Oral health support
Breath freshness applications

Research has also investigated the potential role of EGCg in broader nutritional and therapeutic applications, including viral and immune-related areas of interest.

EGCg and Weight Management

Studies investigating green tea catechins have demonstrated that EGCg may support metabolism and fat oxidation. Some clinical evaluations reported reductions in body weight and body mass index (BMI) with daily EGCg intake levels ranging from 150–300 mg per day.

These effects are commonly associated with thermogenic support and increased fat metabolism.

Traditional Use of Tea Extracts

Tea and tea-derived extracts have a long history of use in traditional Chinese medicine and have traditionally been used in a variety of wellness and health-supporting applications.

Modern green tea extracts such as Teavigo® combine this traditional heritage with advanced extraction and standardization technologies suitable for contemporary nutritional formulations.
