What is an EGCG Supplement?

An EGCG supplement is a concentrated dose of epigallocatechin gallate, a powerful antioxidant found in green tea. While you can get EGCG from drinking green tea, supplements provide a much higher, more standardized amount. EGCG is studied for its potential health benefits, including support for metabolism, heart health, and antioxidant activity.

Best Practices for Buying EGCG Supplements

When looking to buy an EGCG supplement, consider these factors:

Source: The EGCG should be extracted from green tea, with the label often indicating "Green Tea Extract" as the source.

Third-Party Testing: A reputable supplement will have been tested by a third-party organization (like NSF International, USP, or ConsumerLab.com). This verifies that the product contains what the label says it does and is free from contaminants.

Caffeine Content: Green tea extract naturally contains some caffeine. Check the label to see whether the product is decaffeinated or lists the caffeine content per serving, especially if you are sensitive to caffeine.

Other Ingredients: Review the "Other Ingredients" section. Reputable brands keep these to a minimum, avoiding unnecessary fillers, artificial colors, or preservatives.
