The production of important hormones that influence mood, such as serotonin, and B vitamins, especially folic acid, biotin and vitamin K. Healthy, normal immune system function.
My year old Border Terrier had a severe case of diarrhea which lasted a few days.
I ordered complete probiotics and it arrived very quickly.
I was surprised, and a tad disappointed, that the tub isn't full ( less than 3/4 ? )
It comes with a wee measuring spoon inside.
I added a measure to some scrambled egg and within a day Bob ( my Border Terrier ) was producing very solid stools - so, it definitely did the trick for him.
I have since monitored his movements and I use half a measure every other day, which is working great for Bob.
I would say, overall, this is an excellent product but a tad expensive ... and yet much cheaper than a trip to the vets.
