A small controlled study involving 16 Siberian husky sled dogs under intense exercise stress found those fed a tryptophan-enriched dog food (with a ratio of tryptophan to large neutral amino acids [LNAA] of 0.075:1) for 11 weeks had better stool consistency than those fed standard food (with a ratio of tryptophan to LNAA of 0.047:1)

Others are "slow and steady" types who notice gradual improvements over several weeks
