Vitamin B*2 is an essential vitamin that is absorbed through the
intestine. Where an animal has a pancreatic insufficiency intrinsic
factor, which is essential for the absorption of B*2, is not
produced leading to a deficiency in vitamin B*2. Our product
contains intrinsic factor which allows it to be absorbed by the
animal, without the presence of the intrinsic factor the B*2 would
pass straight through the intestine resulting in a progression of
the deficiency.
