Green tea is a staple of traditional Asian medicine and cuisine, but in recent decades it has become popular in the West thanks to studies showing the many health benefits of green tea.
Epigallocatechin gallate (EGCG) is the main compound in green tea that’s known to have health-enhancing properties. Here is what research says about EGCG and which EGCG supplements are worth buying.
Introduction to EGCG
Also known as epigallocatechin-3-gallate, EGCG is one of the most potent antioxidants found in green tea, called catechins. Catechins’ bioavailability in green tea is often too low for significant health benefits, which is why extracts and EGCG supplements have great potential.
Research shows a variety of minor but important health benefits of EGCG. It seems to increase energy expenditure and fat oxidation, and green tea consumption could also decrease carbohydrate absorption. These effects highlight the weight-loss potential of green tea and EGCG.
EGCG has minor effects on blood flow, oxygen uptake, insulin sensitivity, cerebral blood flow, glucose, and HDL cholesterol homeostasis. It can also reduce diastolic blood pressure, heart rate, and LDL cholesterol. Some studies have hinted at possible anxiety-reducing effects of EGCG through interaction with GABA receptors. It’s also reported to stimulate the immune response, with possible senolytic effects.
The ability of EGCG to induce apoptosis and eliminate damage and tumor cells has excellent potential for skincare products. Research shows that topical application of EGCG or green tea benefits UV-damaged epidermal cells, helping ease sunburn. Also, EGCG seems to improve skin hydration, moisture retention and decrease wrinkle formation for an anti-aging effect.
When talking about EGCG dosage, 400-500 mg per day seems to be most effective. The amount of EGCG in a cup of green tea usually varies between 50-100 mg, so you’d need to drink a lot of tea to experience these benefits. Additionally, the European Food Safety Authority (EFSA) warns that dosages over 800 mg/day can induce liver damage, so people need to be cautious about staying within limits.
EGCG vs Green Tea Extract
Green tea extract contains many catechins besides EGCG. They include catechin, epicatechin, gallocatechin, epigallocatechin, epicatechin gallate, and EGCG. So, green tea extracts will get you several of these compounds, although research is still not set on whether this has any health benefits.
EGCG is the primary compound found in green tea extracts, but many labels are standardized to show the overall catechin amount– or simply the amount of extract. On average, most brands state that their extracts contain about 50% of EGCG, so you’ll need around 1 gram of green tea extract with EGCG to get the daily 400-500 mg.
