  • About Green Tea Extract Powder

    Green Tea Extract Powder is a concentrated extract from Camellia sinensis leaves, standardized to a minimum of 45% EGCG (epigallocatechin gallate). Unlike regular tea leaves that undergo oxidation, this extract preserves the polyphenols and catechins that support metabolism, cardiovascular health, and cellular function through natural thermogenesis and antioxidant activity.

    Our Green Tea Extract Story

    Most green tea supplements on the market are little more than ground tea leaves with unknown potency and inconsistent catechin content. Without standardized EGCG levels, customers had no way to gauge the actual potential of their green tea supplement. This created a significant gap between the research showing green tea's benefits and what people were actually getting in their bottles.

    Our Green Tea Extract bridges this gap by standardizing to a minimum 45% EGCG content, ensuring each serving delivers the concentrated catechins that drive green tea's metabolic and cellular health benefits. Our extraction process preserves the full spectrum of beneficial polyphenols while removing most of the caffeine, giving you the active compounds without the stimulant effects. Third-party testing verifies both purity and potency, so you know exactly what you're getting with every scoop.

    Benefits

    • Supports Healthy Metabolic Function: The polyphenols and catechins in Green Tea Extract support thermogenesis, helping your body burn calories more efficiently while supporting healthy body composition and metabolism.
    • Supports Healthy Cholesterol Levels: The 45% EGCG content promotes cardiovascular health by supporting cholesterol levels already within the normal range.
    • Supports Cellular Antioxidant Activity: The four catechins (epicatechin, epigallocatechin, epicatechin gallate, and epigallocatechin gallate) provide antioxidant support to protect cells from oxidative stress.
    • Supports Healthy Fat Oxidation: Green Tea Extract promotes the body's natural ability to utilize stored fat for energy, supporting healthy weight management and exercise performance.

    Regular green tea contains significant caffeine, but this concentrated extract with high EGCG content contains only trace amounts of caffeine, making it ideal for those seeking metabolic benefits without stimulant effects. The extract's bioavailability increases when paired with fish oil supplement or combined with CoQ10 supplement for complementary effects.

    Quality and Standardization

    • EGCG Standardization: We standardize our Green Tea Extract to a minimum 45% EGCG content, ensuring consistent potency of the most bioactive catechin responsible for the majority of green tea's health benefits.
    • Low Caffeine Content: Unlike regular green tea beverages that contain 35-100mg of caffeine per cup, our high-EGCG extract contains only trace amounts of caffeine, making it suitable for those sensitive to stimulants or taking it later in the day.
    • Comprehensive Catechin Profile: Our extract contains all four primary catechins (epicatechin, epigallocatechin, epicatechin gallate, and epigallocatechin gallate) in their natural ratios, providing the full spectrum of antioxidant support benefits.
    • Third-Party Verified Purity: Each batch undergoes rigorous lab testing to verify both product purity and identity, ensuring you receive precisely what's on the label without contaminants or adulterants.
    • Enhanced Bioavailability: Our extract shows improved absorption when paired with fat-soluble supplements, and synergistic effects when combined with longevity compounds like CoQ10 or curcumin.

    Mechanism of Action

    • EGCG Bioavailability: The catechins in green tea extract work through enhanced absorption in the intestinal tract, where EGCG crosses cellular membranes to access target tissues and organs throughout the body.
    • Mitochondrial Function: EGCG supports cellular health by enhancing mitochondrial efficiency and supporting these cellular powerhouses during energy production.
    • Fat Oxidation Pathways: The polyphenols activate specific enzymes involved in fatty acid breakdown while supporting enzymes responsible for fat synthesis, creating a dual mechanism for metabolic support.
    • Antioxidant Network: Green tea catechins function as part of the body's antioxidant network, regenerating other antioxidants like vitamin C and vitamin E to maintain cellular protection.

    Overview of the Science

    Green Tea Extract supports healthy metabolism through multiple pathways beyond basic thermogenesis [1][2]. Research indicates that EGCG enhances fat oxidation during exercise and supports healthy weight management over time. Studies have shown that green tea catechins work synergistically with caffeine supplements to promote metabolic efficiency, even though our high-EGCG extract contains minimal caffeine content [1]. The polyphenols also support cardiovascular wellness by promoting healthy cholesterol levels already within the normal range [3][4].

    The cognitive benefits of green tea consumption have been documented in several population studies [6][7]. EGCG crosses the blood-brain barrier and supports healthy brain function through multiple mechanisms, including protection of neurons from oxidative stress and support for healthy neurotransmitter activity. Research suggests that green tea extract supplementation supports cognitive performance in healthy adults, particularly in areas related to attention and working memory. These brain health supplements effects appear to be dose-dependent and most pronounced with consistent long-term use [6].

    Athletic performance and recovery represent another well-researched application for green tea extract [8][9]. The polyphenols in EGCG provide antioxidant support to help maintain the body's natural response to exercise-induced oxidative stress, potentially supporting faster recovery between training sessions. Studies suggest that green tea extract supplementation helps preserve neuromuscular function during periods of intense training while supporting a healthy inflammatory response post-exercise [9]. These benefits make green tea extract a valuable addition to comprehensive fitness nutrition protocols.

    Ingredients

    Green Tea Extract Powder:

    • Camellia sinensis leaf extract
    • Standardized to minimum 45% EGCG (epigallocatechin gallate)
    • 500mg per serving

    The 45% EGCG standardization represents one of the highest concentrations available in the supplement market. This precise standardization ensures you receive consistent levels of the most bioactive catechin in every serving, rather than variable amounts found in unstandardized green tea powders. EGCG concentration directly correlates with the extract's potency for supporting healthy metabolic function and anti oxidative stress supplements, making this standardization level essential for therapeutic benefits.
