Amino-acid generally compete for absorption and are therefore recommended to take separate. The competition isn't however anywhere from complete. Otherwise since ancient times we wouldn't have survived from natural proteins all mixed.
I do find a BCAA deficiency on a ketogenic diet highly unlikely, since so many low carb foods contain a lot:

I’m not clear as to where I'm missing the point, but here’s what I
think your post is getting at (sorry, brain dead from lack of sleep).
Yes, usually all, or most, amino acids occur in protein-rich foods, and are all beneficial to the body, which uses them as needed to make proteins, effect repairs and maintenance, and conduct its brainy-ish business, and stores any excess as fat.
But just as tryptophan, when taken to induce sleep, needs to be taken in the
absence of other amino acids in order to avoid competition with those other amino acids and be effective as a sleep aid (the brain doesn’t differentiate, building blocks are building blocks as far as it’s concerned and it just grabs whatever comes thru its door first), BCAAs will function best for increased energy and for the alleviation of prolonged PEMS episodes when taken
away from other, competing and diluting, amino acids.
The difference between your intake of BCAAs as part of a complete protein array of amino acids lies in its utilization, not just it’s presence. Leucine, isoleucine, and valine are present as part of a complete protein and will have a greater or lesser effect, based on what makes it to the factory first.
Take a look at the
@Mary thread, where BCAAs and their function are clearly explained, much better than I can do today with my poor, battered brain
.
If I don't get back to you right away with any follow-up, it's because at some point I'm going to have to take a little lie down, I've been up for nearly a full day with almost no sleep and I'm finally beat enough to maybe get some shut-eye.
Ha. Famous last words.
