About Epigallocatechin Gallate
Epigallocatechin gallate (EGCG) is a polyphenol antioxidant predominantly found in green tea extracts. It is available as a dietary supplement and is studied for its potential benefits, including cardiovascular health, weight management, neuroprotection, antioxidant, and anti-inflammatory properties. While generally considered safe at moderate doses, high doses of EGCG can lead to gastrointestinal distress and, in rare instances, liver problems. It may also interfere with iron absorption and interact with certain medications. Individuals considering EGCG supplementation should consult with a healthcare professional, particularly those with pre-existing health conditions or those taking medications.
