Green Tea Extract Linked to Liver Damage

Green Tea Extract Linked to Liver Damage


I might be late to the game on this, but apparently green tea extract, specifically EGCG has been linked to liver damage. Granted, it’s only a correlation, not necessarily causation. I took 1g per day for 3 months during my competition shred. My blood work ALT and AST were normal during this time, but I’m not going to take chances with it next time.

I only found out this week because of a Lifehacker article.

NIH Article:


Green tea extracts are widely used without problems. For me , it seems one of 2 possibilities:
Some people are genetically more (a lot more) affected in a way that damages the liver.
Heavy metal contamination. Green tea might contain quite dangerous levels if sourced from cheapest place.
