Hi,
Someone I know has been taking 300 mg EGCG daily (as green tea extract) with piperine. From what I've read, 300 mg EGCG daily seems safe, without potentially raising alanine aminotransferase and causing liver problems down the line but I'm not sure how the addition of piperine changes things... Yes, I know the piperine would increase EGCG bioavailability but would it not also increase the potential for liver toxicity (by making the EGCG even more potent)? So this is a two part question: Is 300 mg EGCG + piperine daily safe? And would piperine ALONE present any health issues? In other words, is piperine generally a good idea from a safety standpoint? I've read that piperine is acutely toxic to mice, rats and hamsters. Not sure how it translates to humans but I would appreciate any comments related to this. Thank you in advance. Oh, and also, I'm not sure how much piperine is in the EGCG product but I opened a capsule, tasted it and could tell that it was very strong, very pungent.
