My father is a physician and he always tells me to stop taking protein shakes because they are bad for my liver. He keeps telling that he has had a few teenage patients with liver problems because of taking protein supplements. At first I didn't believe him but I just got a blood test and my liver enzymes showed up unusually high. My father of course said that I need to dump out my protein powder because this was one of the main reasons for my liver enzymes being high. Have there been any scientific studies done about this? If so I would like to know please because I'm curious.

btw i am not calling your father ignorant at all, i guarantee that some/most of the teens he has heard of/seen who use proteins have been using a hormonal related product (prohormones) aka legal steroids. this explains the liver enzyme level fluctuations and liver deficiencies they may be facing.

OK. Time to interject some science into the fiction here.
Whey Protein actually has been shown to reduce the amount of liver enzymes (ALT and AST) and increase the concentration of glutathione, which is an antioxidant that protects the liver cells in people who have a "fatty liver", or elevated liver enzymes in a routine blood screen. People who have elevated enzyme results and fatty inflamation have a condition called steatohapatitis.
This is directly from the Journal of Gastroenterology Hepatology, 24: 1045-1050, 2009.
Now I am not trying to say you father is wrong, but scientific evidence is pointing the other way. And for the record, I am not a physician...just a Ph.D Food Scientist.

My doctors after two years have got this problem under control and said I could return to lifting as much weight as I wanted to now but to not take creatine or whey protein because they were like poison to my system. Why this is I don't know I did not go into all the detail with him I was just pleased to be able to return back to the gym and start training again. I hope this gives you some kind of insight that you were looking for. Just for the record I believe I would listen to your father, he sounds like a wise man.

Outside of contaminated products, I dont see how protein drinks directly effect the liver organ. Almost like saying dont eat steak, or drink milk. What made your father conclude the liver issues come from protein drinks and not any other various factors? Other than that, you can always get a second opinion from another doctor.Thermolife Eternal Rep
