The most potent EGCG formula in the world

  • 25-100 times more antioxidant power than vitamins A,C and E
  • Boosts immune system and protects cells from damage

Research-Supported Benefits:

Promotes Longevity. Studies consistently show that green tea drinkers live longer than non-tea drinkers 1. Researchers largely attribute this increase in lifespan in green tea drinkers to the powerful antioxidant compound in green tea known as EGCG. Research shows that EGCG extends lifespan of a variety of organisms, including in mice by as much as 12%. 2

Supports Immune Health. Reseach shows that EGCG has immunomodulatory effects, meaning that it has the capability of regulating the immune system. Immunomodulators, like EGCG, are capable of stimulating certain parts of the immune system to offer immune protection while tampering down others parts of the immune system that may contribute to inflammation. 3

Enhances Cellular Health. Polyphenols and EGCG found in green tea extract have powerful antioxidant effects, reducing levels of oxidative stress 4. Oxidative stress contributes to inflammation and age-related health decline. Research shows a correlation between oxidative stress and longevity, with high levels of oxidative stress decreasing lifespan and health span 5.

Weight Management. EGCG is one of the few supplements that has been clinically shown to effectively support heathy weight management. Research shows green tea consumption or supplementing with EGCG may promote weight loss, reduce waist circumference and improve energy metabolism. 6

  • Green Tea EGCG Extreme™- a powerful green tea extract- is a potent source of polyphenols and EGCG (epigallocatechin gallate) – two antioxidant compounds that are 25 to 100 times more potent than that of vitamins A, C and E – protecting fragile  cells from destructive free radicals. Antioxidants neutralize harmful oxygen-containing molecules in your body called free radicals and peroxides. Stress, exposure to toxins and even the digestion of certain foods creates free radicals. When left unchecked, free radicals can damage your cell membranes and other vital cell components. Antioxidants found in green tea are vital to slowing and even preventing damage caused by free radicals. 
  • EGCG and polyphenols in green tea extract reduce cellular damage from oxidative stress, a key contributor to cellular aging. 
  • Green tea extract supports healthy weight management by improving markers of metabolic health.

Great source of antioxidants. This product has helped me feel noticeable more energized during workouts as well as reducing recovery time. Additionally, it improves my alertness mid-afternoon when need to concentrate on intellectually demanding work while not causing adverse effects during sleep as it avoids caffeine normally present in typical green tea infusions.
