Be careful with the EGCG. I think too much of that can cause liver damage.
That is from “green tea extract” — typically dubious weight loss supplements that concentrate the EGCG into dangerous amounts, typically using lead-tainted Chinese green tea. I would only recommend drinking Japanese organic Matcha tea regularly, which also provides a side benefit of reducing tooth decay. I make my own capsules and have used them for years. I lost 65 lbs with them, and lowered my resting heart rate from 78 to 55 bpm.
