What is Egcg Powder?
EGCG, also known as epigallocatechin gallate. It is the most abundant component of catechin, accounting for 9%-13% of the gross weight of green tea. Because of its special stereo-chemical structure, EGCG has very strong antioxidant activity, and its antioxidant activity is at least 100 times that of vitamin C. 25 times more than vitamin E, it protects cells and DNA from damage.
EGCG is one of the most abundant and biologically active compounds in green tea, contributing significantly to the health benefits associated with tea consumption. In its powdered form, EGCG powder is a concentrated source of this beneficial compound, offering an easy and effective way to enjoy the full spectrum of green tea's health-boosting properties.

Furthermore, EGCG is known to improve cognitive function, protect the brain from age-related decline, and may even help support mental clarity and focus.

EGCG, EC, EGC theanine application distinction
Tea Polyphenols: This general term refers to the entire group of plant-based compounds in tea, including catechins like EGCG and EGC, and flavonoids like quercetin. Tea polyphenols are known for their potent antioxidant, anti-inflammatory, and anticancer properties. They are used in supplements, skincare products, and functional beverages due to their broad health benefits.
EGCG: As discussed, EGCG is the most powerful and well-researched catechin found in green tea. It is particularly effective at supporting weight loss, cardiovascular health, and cognitive function. EGCG is most commonly used in supplements, teas, and beauty products for its ability to fight oxidative stress and reduce inflammation.
EC (Epicatechin): EC is another catechin found in green tea, although it is present in smaller quantities than EGCG. It is known for its cardiovascular benefits, including improving blood flow, reducing blood pressure, and lowering cholesterol. EC is often used in sports nutrition products due to its potential to enhance endurance and exercise performance.
EGC (Epicatechin Gallate): EGC is a close relative to EGCG but with slightly different properties. Like EGCG, EGC offers antioxidant and anti-inflammatory effects. However, EGC is more often associated with liver health and detoxification. It is also used in skincare and beauty products for its ability to promote healthy skin.
Theanine: L-theanine is an amino acid found in green tea that provides a calming effect and promotes relaxation without causing drowsiness. It is often used in combination with caffeine to reduce the jittery effects associated with coffee, offering a balanced and focused energy boost. Theanine is typically used in mood-enhancing supplements, teas, and sleep aids.
