Green Tea Extract (Std. to 50% Polyphenols, 30% Catechins, 15% EGCG)

Green Tea Extract (GTE) is derived from the leaves of Camellia sinensis, a plant renowned globally for its health-promoting properties. Our specific extract is meticulously standardized to contain a minimum of 50% total polyphenols, 30% total catechins, and 15% epigallocatechin gallate (EGCG), ensuring a consistent and potent profile of its primary bioactive compounds. This standardization is crucial for reliability in supplement formulations, providing a predictable dosage of key phytonutrients. Historically, green tea has been consumed for thousands of years in East Asian cultures, valued for its invigorating and health-supporting attributes. The extraction process carefully isolates these beneficial compounds, concentrating them into a convenient form that retains the essence of the raw plant material while enhancing bioavailability. This carefully controlled process results in a high-quality ingredient suitable for diverse applications in the nutraceutical industry.

The health benefits of Green Tea Extract are primarily attributed to its rich content of polyphenols, particularly the catechin group, with EGCG being the most prominent and extensively studied. EGCG acts as a powerful antioxidant, scavenging free radicals and reducing oxidative stress, a mechanism supported by numerous in vitro and in vivo studies (e.g., studies published in the Journal of Nutritional Biochemistry). Beyond its antioxidant capacity, EGCG has been shown to modulate various cellular signaling pathways, influencing metabolism, inflammation, and cellular proliferation. Research suggests GTE can support cardiovascular health by improving lipid profiles and endothelial function, as evidenced in meta-analyses of randomized controlled trials. Furthermore, catechins contribute to thermogenesis and fat oxidation, making GTE a valuable ingredient in weight management formulations by potentially enhancing metabolic rate and supporting fat metabolism.

Green Tea Extract, standardized to its potent catechin profile, finds widespread application in dietary supplements targeting various health areas. It is commonly incorporated into formulations for weight management, cardiovascular support, cognitive function, and antioxidant defense. Its versatility extends to encapsulated products, powders, and functional beverages. High-quality GTE production involves stringent quality control measures, including heavy metal testing, pesticide screening, and microbial analysis, to ensure purity and safety. Scientific evidence continues to accumulate, with studies like those published in Phytomedicine exploring its neuroprotective effects and impact on glucose metabolism. For instance, a systematic review in Advances in Nutrition highlighted EGCG's potential role in supporting immune function and cellular health. The consistent standardization to 50% polyphenols, 30% catechins, and 15% EGCG ensures formulators can rely on its consistent efficacy, making it a cornerstone ingredient in evidence-based nutritional products.
