That's interesting. I have a protein shake which has pretty much the full spectrum of amino acids, including ~500mg tryptophan and lots of BCAAs like (iso)leucine.
It definitely helps me recover and I feel much better the day after than without, which I thought was partly due to the tryptophan content (as I don't take 5-HTP). It's probably just preventing malnutrition then (all high bioavailability, easy to absorb even by my decrepit post-roll body), seeing as if I don't drink one I probably wouldn't be able to eat anything.
