There is more than a couple of these same questions answered but they are answered by dumb people saying too much protein won't do anything!!! I am not asking about protein, I am asking about protein shakes. Due to a hectic schedule I am planning on getting 100 grams of protein from a mixture of whey and casein shakes. I am asking if this much amount of protein POWDER can harm my body. I weigh around 250 pounds and I am eating around another 100 grams of protein from regular food. My only concern is if the high concentration of whey protein powder will harm me and how much would it take. And I already know too much of anything is bad or if you take it for a long time its bad but I'm asking if it will harm me short term or evidence that it will harm me long term OR evidence that this much protein from protein powder a day will not harm me at all.

Is taking protein powder bad for your livers or kidneys?

Nothing negative will happen if you get in too much protein. There's no evidence of it being bad for your kidneys even though for some reason that seems to be a common thought. There's not a shred of evidence to back that up. If you've taken in more protein than your body has use for, it'll be oxidized as fuel.

That's a lot of shakes per day. Not saying that it's necessarily harmful, but you would be much better off getting the majority of your protein from real food. I mean if your schedule is too hectic to find time for enough real meals for that then that is tough but 5 shakes is a lot...

it sounds like you want us to tell you it's going to harm you because that's either the conclusion you've come to on your own or that's something someone at school or GNC or your mom told you

No I've actually heard from one doctor and plenty of people on the forum but no one had evidence to back it up that it actually causes damage. I was looking for someone who had the knowledge or someone who already drinks that much in protein powder to tell me their experience. So your helping me confirm that it's okay. And thanks.

I read through it all and I have already decided to stick with five shakes 20 g each along with another hundred from meals. But in the studies involving kidney and liver damage they were based on high protein diets not stating whey or not, or they were based on low whey protein diets only 20 g. So to me still no conclusion but from the information I've gained so far it's safe to do what I'm doing and no health problems will come up in the future. I hope haha. Thank you everybody for your input. If anyone comes up with hard evidence I would still like to know. Thanks again.

The high protein is bad for you gets blown out of proportion, especially since most of the meat heads that mess them self's up on high protein diets are probably juicing. I do have to add though that 100g from food is pretty low, I can almost get that in one meal. Not criticizing, but whole food tastes so much dam better than shakes. Drinking five shakes would suck.

you will find that family doctors, whether it's because they're afraid of malpractice suits or they're just horribly ignorant, are some of the worst people to ask about diet and supplements...they know how to prescribe meds and diagnose strep throat and for many, that's about all they're good for, so they're almost ALWAYS going to tell you that you should be careful and not do too much of anything and blah blah blah just so you can't come back and sue them

Some general thoughts, not to be confused with medical advice
If you're healthy and do not have kidney problems then high protein intake is unlikely to be harmful to you. If your kidneys are not in great health then yes high protein intake is not good. If you have high blood pressure, diabetes, or other conditions that negatively affect kidney function you will not want to take in a ton of protein. For the healthy individual high protein intake is likely fine, just be sure to stay well hydrated to make it easier on your kidneys. In general the excess protein that your body doesn't need for protein synthesis is just going to be burned or stored as fat.

Okay I'm a full time student and I work so I only actually eat twice maybe three times a day but here's another thing that I've heard. When consuming a high amount of protein only some of it is used and the rest is wasted. So when eating 100 grams of protein from a single meal, how much is actually used? I've heard anywhere from 20-40. If I knew that my body would absorb all the protein I ate I wouldnt need the shakes but Im trying to spread the time of day I eat and drink the shakes so nothing is wasted. Overall question: how much protein can you eat in one meal that will all be used, no left over turning to fat or fuel.

I have actually run blood test for my liver/kidney enzyme levels while on or not on supplements.
A few years ago my ALT/AST levels were in the 35-40 range. I was 165lbs and taking a gainer in the morning, whey postWO and creatine.
Getting about 150g of protein a day.
Recentlly ive done another test and currently im in the low 70's range which is boarderline close to above normal. NOw im on the same proteins, different creatine and different preWO supplements. I also eat way more 300g of protein per day and I weight 205.
I went back 30 days later and rerun the test because i stopped my creatine usage. I was in the same numbers. So my elevated levels arent due to creatine or preWO because during this period I had a bunch of different sample packs and have been taking all different types of preWO's. (C4,jack3d, white flood, N-Zero, SP Max).
So in the end my doctor said compared to someone who has 2 beers a day their ALT/AST levels are in the 90's so in retrospect, im fine for now. He didnt know what caused the jump. But I can only speculate the fact that im eating more and getting 300g of protien per day.BPI Brand Ambassador

I could have worded that better. Powders are a great source of aminos and have a fantastic level of leucine, but they're not exactly like a piece of chicken. But if someone were to ask if it's ok to use a protein powder i'd respond with asking them if it's ok to eat meat.
