Green Tea Extract (EGCG): Benefits, Uses and Long Term Effects
Green tea extract, and in particular its active component EGCG (epigallocatechin gallate), is among the most powerful antioxidants known for its numerous health benefits. From aiding metabolism to protecting the heart and cells from oxidative stress, green tea is an essential element in many health regimens. In this country, green tea is well known and popular, but the amount needed to achieve therapeutic benefits through tea consumption would be extremely high. Therefore, supplementation with green tea extract is becoming increasingly important for maintaining optimal health.
What is EGCG?
EGCG is a bioactive polyphenol that is the main catechin in green tea. It has powerful antioxidant and anti-inflammatory properties that protect cells from damage and reduce the risk of chronic disease. Although it can be sourced through green tea consumption, the concentration of EGCG in one cup of tea is relatively low. For example, to get about 300 mg of EGCG (the dose needed for therapeutic effects), you need to drink between 4 and 6 cups of green tea. This makes supplementation with EGCG a more effective and practical way to secure its benefits.

Health benefits of green tea extract (EGCG)
- Helping cardiovascular health
EGCG is known for its cardioprotective properties. Той подобрява функцията на кръвоносните съдове, намалява нивата на “лошия” LDL холестерол и помага за контролиране на кръвното налягане. Проучвания показват, че редовната употреба на EGCG може да намали риска от атеросклероза и сърдечни заболявания.
In Bulgaria, where cardiovascular disease continues to be a leading cause of death, EGCG supplementation may be a key factor in improving heart health. - Improve metabolism and weight management
EGCG is known for its thermogenic propertieswhich means it helps burn fat and speeds up metabolism. This makes it useful for people who want to lose weight or maintain a healthy weight. It also helps to regulate blood sugar, which is particularly beneficial for people with diabetes or a pre-diabetic condition.
A study published in American Journal of Clinical Nutritionfound that EGCG increased fat oxidation by up to 17% in people who regularly consumed green tea or supplements with EGCG. - Antioxidant protection and cell protection
As a powerful antioxidant, EGCG neutralizes free radicals and protects cells from oxidative stress, which has been linked to aging and the development of chronic diseases such as cancer and heart problems. This powerful antioxidant helps to reduce inflammatory processes and protect DNA from damage.
In times of increased pollution and stress, which are common in Bulgarian cities, EGCG supplements provide reliable protection of the body against external aggressors. - Support for brain function
EGCG not only protects cells in the brain, but also improves cognitive function and concentration. Изследванията показват, че редовната консумация на EGCG може да помогне за подобряване на паметта и намаляване на риска от невродегенеративни заболявания като Алцхаймер.
A study published in Journal of Nutritional Biochemistry, shows that EGCG has the ability to cross the blood-brain barrier, allowing it to directly impact brain function and protect neurons.
How much EGCG is needed?
Although green tea is popular and affordable, to achieve therapeutic benefits, tea consumption must be very high. On average, one cup of green tea contains about 50 mg of EGCG, which means that to take the recommended dose of 300 mg, you need to drink at least 6 cups of tea per day. This can be challenging for most people, especially given the caffeine levels in green tea.
Green tea extract supplements provide an easier way to get optimal amounts of EGCG without the need to drink large amounts of tea. For example, one capsule of a green tea extract supplement can contain 100-500 mg of EGCG, which is equivalent to several cups of green tea.
Long-term effects of EGCG use
- 6 months: Improved metabolic function, better circulation and reduced body fat level.
- 1 year: Sustained cardiovascular health, improved cognitive function and lower risk of chronic disease.
- Long-term antioxidant protection: Consistent use of EGCG can reduce the risk of oxidative stress and protect the body from harmful external factors.

Recommended dosage and use
Green tea extract supplements often contain between 100 and 500 mg of EGCG, this amount is sufficient to achieve therapeutic results. В In Cellgreen tea extract is formulated to provide maximum absorption and effectiveness. Take three capsules dailyto reap all the benefits EGCG offers for metabolism, heart health and cell protection.
EGCG is a potent component of green tea extract that offers a number of health benefits including improving metabolism, protecting the heart and brainas well as antioxidant protection against oxidative stress. Although it can be obtained by consuming green tea, the doses needed to achieve optimal benefits are high and difficult to obtain through diet alone.
Supplements with green tea extract, such as those in Aeterna Cell, provide an easier and more effective way to get all the benefits of EGCG without the need to drink multiple cups of tea daily.
