1) Quick Overview

As you know, green tea has potent antioxidant properties. These antioxidant properties are derived from ingredients called catechins, also known as green tea catechins or GTC. The catechins in green tea are four molecules, large quantities of which are present in green tea and other sources. Out of these, the most potent and effective is EGCG. All the benefits of EGCG-improving cognition are dependent on being caffeine naive. Recent studies have shown that EGCG could be a powerful natural cognitive enhancer.

Green tea has been known to boost metabolism and enhance your body’s natural properties in improving the brain health. For years, green tea extracts have been used in brain formulas and diet pills, where it is prized for its caffeine, flavonoid and catechin content. Together, these three active ingredients lead to powerful advantages. However, recent studies have shown that flavonoids and caffeine only play a minor role compared to the primary green tea catechin,” the EGCG.” EGCG is a unique catechin that can stimulate blood circulation, improve brain health and increase concentration and focus.
