The properties of Green Tea
The use of green tea extract (Camellia sinensis) results in accelerated fat burning during sleep and prevents the development of obesity. Studies have shown that green tea reduces the amount of bad cholesterol, stimulates the oxidation of fatty acids, supports thermogenesis of the body, and is a powerful antioxidant that protects against the negative effects of free radicals.
It has proven to decrease the appetite, speed up the metabolism and facilitate the digestion of fats in difficult places. Reports have shown that green tea extract intake is associated with increased weight loss due to diet-induced thermogenesis, which is generally attributed to the catechin epigallocatechin gallate. That catechin-polyphenols are known to be capable of inhibiting catechol-O-methyltransferase (the enzyme that degrades norepinephrine) is a possible explanation for why the green tea extract is effective in stimulating thermogenesis by epigallocatechin gallate to augment and prolong sympathetic stimulation of thermogenesis.
Fat can’t be burned until it’s broken down in your fat cells and moved to your bloodstream, but the compounds in green tea can boost your fat burning hormones. Norepinephrine is a chemical that instructs fat cells to break down fat. EGCG, the main antioxidant found in green tea, inhibits an enzyme responsible for breaking down norepinephrine. This results in an increase in norepinephrine, which can increase the amount of fat your body breaks down.It is even thought that caffeine and EGCG, both of which occur naturally in green tea, work together because caffeine works to the same effect as EGCG. This means more fat loss because your muscle cells, along with other body structures, will use the fat for energy (that you can then use at the gym). Research has shown that green tea extract is associated with increased weight loss due to diet-induced thermogenesis.

Green Tea Extract:
- Promotes anti-oxidant activity (Green tea catechin, epigallocatechin-3-gallate (EGCG): mechanisms, perspectives and clinical applications).
- Supports mood (Effects of dietary supplementation with the green tea polyphenol epigallocatechin-3-gallate on insulin resistance and associated metabolic risk factors: randomized controlled trial).
- Promotes fat reduction (Green tea catechin consumption enhances exercise-induced abdominal fat loss in overweight and obese adults, Effects of catechin enriched green tea on body composition).
- May improve cognitive function (when paired with L-Theanine) (A combination of green tea extract and l-theanine improves memory and attention in subjects with mild cognitive impairment: a double-blind placebo-controlled study).
- Supports cardiovascular health (Effects of green tea and EGCG on cardiovascular and metabolic health).
