What is Green Tea Extract Powder (50% EGCG)?
Green tea extract comes from the Camellia sinensis plant, as does white tea, yellow tea, oolong tea, dark tea, and black tea. Green tea is the least oxidized of the teas and contains the highest levels of Epigallocatechin Gallate (EGCG). EGCG is one of four catechins found in green tea and exerts the most potent effects. Green tea extract owes many of its benefits to its EGCG content. It has antioxidant and anti-inflammatory properties. It also supports heart and brain health and may enhance fat loss. Green tea extract may improve skin health and exercise performance as well.
PureBulk’s Green Tea Extract Powder contains at least 50% EGCG.
Potential Green Tea Extract Benefits
Green Tea Extract is Rich in Antioxidants
Green tea isn’t fermented like black tea, allowing it to retain its polyphenols and catechins like EGCG. Polyphenols and catechins are natural antioxidants that protect the body from free-radical compounds that destroy healthy cells. EGCG also inhibits pro-inflammatory cytokine activities. In clinical studies, polyphenols provided more antioxidant protection than vitamin E or vitamin C. Polyphenols also improve the performance of the body’s own natural antioxidant enzymes, including glutathione, a tripeptide that minimizes inflammation and protects cartilage. EGCG’s antioxidant activity also protects brain cells from oxidative stress and heavy metal activity.
Green Tea Supplements + Heart Health
Green tea extract increases the natural antioxidant potential in the blood. It also reduces LDL cholesterol oxidation by simultaneously settling on LDL cholesterol particles and sequestering adjacent free radicals. It also acts as a vasodilator to expand the arteries for improved blood flow. Researchers theorize this is because green tea catechins enhance nitric oxide’s bioavailability. Green tea catechins also exert significant inhibitory effects against the enzymes that convert squalene into cholesterol.
Green Tea Supplements + Exercise Performance
The antioxidants in green tea reduce oxidative damage and may delay muscle fatigue. One study noted that green tea extract enhanced the body’s antioxidant protection when combined with strength training. Another study showed that green tea extract protected sprinters against oxidative damage during repeated sprint tests. A different clinical trial reported that participants increased their running distance by 10.9% over a four-week period compared to the placebo group.
Green Tea Extract + Weight Loss
Combining green tea extract with caffeine exerts synergistic effects on weight loss. The combined compounds modulate hormones to enhance how many calories the body burns to digest food and generate body heat (thermogenesis). Increasing the body’s innate ability to burn calories may facilitate more weight loss. One study noted that participants burned about 179 calories more over a 24-hour period after taking caffeine and green tea extract. However, these effects are more noticeable in individuals who don’t regularly consume caffeine.
Green Tea Extract and Skin Health
Green tea extract may improve several aspects of skin health. Topically, it helps relieve redness and irritation. It may improve the overall appearance of the skin by helping with acne, moisturization, and skin aging. Multiple studies noted that topical green tea extract reduced inflammation, premature aging, and the loss of skin elasticity. It may reduce the damaging effects of UV rays, too.
