Limit to how much protein a person can use at one time?

Good afternoon! I have seen many times on here people saying that a person can only absorb a certain amount of protein at one time. I have seen 30 grams, 45 grams and 50 grams being the limit. Some people say it is not true, including my NUT.

So I guess I am wondering...is there a limit? If you say yes, do you have a reference you can share? And if there is an amount limit, there must be an amount of time that needs to pass before you can have more? Until food is digested? I guess the whole protein limit thing doesnt make a lot of sense to me, especially since multiple protein supplements are over 30 grams, and even some 50 or more.

Thanks everyone!

I'm hearing that there isn't really a limit unless you have kidney or liver issues as they must help with protein metabolism. 

"Limits" for kidey or liver issues has to do with limiting the amount of protein you take in to prevent "overwhelming" the organ with byproducts of protein metabolism/breakdown... versus a limit of how much the body can absorb.
Limiting intake for liver or kidney issues should be only under recommendations of an MD/RD and be specific to the stage of the disease and other treatments.

According to both the ASMBS and the NIH, the protein absorption limit is a myth:

Thanks for sharing the links! I thought it was a myth, I am just glad to see an article about it.

I wasn 't advised of any limits by my program.

I wasn't told any maximum limit either...just to make sure I got 70 + in a day

I've wondered the same thing as i drink about 60-72 grams of protein in the morning time (Spread across about 3 hs). Although my nutritionist like your's has said this is fine. :)

Barring extreme cir****tances, this should almost surely NEVER be a concern of a post-op. We malabsorb protein so our bodies are perpetually in need of it. And if you talk to many vets, even ones who eat mega-high protein, their labs only run in the normal range at best but more likely on the low end of normal or low.

So eat your protein!
