Digestive health:2nd time buying already this probiotic, it's very clear to me its helping my dog's digestion and overall health, he scratches less, licks his paws less and also his flatulence/gas/farting is alot reduced. Nutrient absorption:Like I said before, I can't measure and tell you how precise the absorption is, but following the amount on the instructions for my dog's weight seems to be good enough
