Hello guys
A fellow colleague of me wrote me on skype. he said protein supplements are REALLY bad for your liver.
Is this true or false?
Here is the conversation:
colleague: "oh ya btw"
colleague: "one more info.."
colleague: "protein supplements..."
colleague: "they are REALLY bad for your liver..."
me: "aha?"
me: "who told you / where did you read that?"
colleague: "doctor...biochem book...science journal"
me: "ok"
me: "I'll read some about it =)"
colleague: "mhm! you should"
Can someone explain?

There's no scientific evidence supporting the claim he's making. It's just protein, which doesn't harm the liver. When you intake protein, your body breaks it down, then rearranges it into a type of protein which can be used for different uses in the body, i.e it doesn't detoxify it, break it down for disposal, or anything like that, as it would substances like alcohol, drugs...etc. Your friend is a dolt.
I'm what Willis was talkin' 'bout.

Hello my friends
I knew the second he said the stuff. That he was wrong. I just wanted to make it clear to him so he would understand. Answers from you guys justify my thought which I agree with you.
I am actually a second year medical student(here: starting biochemistry next monday!). He is a 3rd year med. student. He studied Biochemistry for one year - and he stated this after that. (I find it odd that he can say such a thing)
Anyways. Thank you all for your replies. You are all appreciated greatly.
He hasn't replied me back after I told him your replies.
I will update when he says something new.

As for synthetic, it's not the amino acid itself that damages the liver. We eat meat everyday and we're still alive now, right?
It's all the other things they use to synthesize the proteins; the catalysts if you must. If they don't get filtered out and we end up drinking them, especially if the catalyst is something like I dunno, lead, there's some srs stuff right there. I think that's what he's getting at.
EDIT: Or the by-products. Accursed by-products.

Colleague: "the question is...the normal protein (non-synthetic) protein is composed of R-type amino acids...which is quite different from the "L"-type amino acids, which would be the constituents of the synthtic protein supplements...now it is my understanding that the synthetics can never have "R" isomer and only "L" isomer. If this is so, how would the "L" type amino acids not affect the human body in any way? perhaps maybe the isomerase would have a role in this, but even so, wouldn't it be more logical to think that the synthetic protein supplement would have SOME sort of effect on the human body, which most probably is antagonistic and increasing the entropy?
and also...about the point on the catalysts and by-products, I couldn't agree more...unfortunately..."

You'd need to take in a LOT of protein to make your kidneys **** up. Increased BUN isn't pathognomonic of a single ailement. It can be plenty of things. I also don't think drinking water helps your kidneys with processing proteins specifically persay, since water isn't needed in the coupled transport of protein/a.a during reabsoprtion.
P.S: BUN=blood urea nitrogen, you didn't have to add UREA after BUN. :PI'm what Willis was talkin' 'bout.

Colleague: "and on my prior "extreme misunderstanding", I think I may have jumped to the conclusion without proper logical processing...the point my doc was trying to make to me was that excess energy provided by the protein supplements that hasn't been used could be stored in the liver and cause Fatty Liver, which would be easier to happen than one might expect, since the protein supplement is substance of extreme calories."

In grave excesses, definitely. As for one or two shakes a day, it's not too much. But a protein is a protein. Even chicken, when consumed in insane amounts for the body to actually used to build muscle, can be stored as fat in the liver.
It's just with powders, it's easier to overshoot because you don't feel as full. But I get where he's going at. Mix 3 scoops of protein powder in water and drink then bam, instant 400 calories. If you don't use it, becomes fat.

Doc told me I'm not drinking enough water after the blood work when he saw the High BUN my liver was in normal range. The more protein consumed, the more fluid the kidneys need to flush out the nitrogen

Protein is of the same calories as carbs, 4 cal/gram. Fat is of 9 cal/gram. So how is protein of "extreme calories"? Even if so, following that logic, its not the protein causing problems, its the calories. So overeating is bad for your liver? Yes overeating is bad. It has nothing to do with protein supplements.
