||The values that researchers obtain under physiological
conditions range from 0.2 to 48
mM, depending on the animal species,
time of day, diet, and intestinal region.
Values never exceed 48 mM under physiological conditions and rarely exceed 28mM. Average values in each species range from 0.4mM in dogs to 24mM in humans.
