If the milk/cream curdles in the stomach, it could absorb the B12.
The probiotics would have a binder in it...a flow enhancer to make the product, and it could bind the B12 too. Complex it chemically so that the B12 would not get to the transcobalamin in the intestinal wall.
We have to assume you don't have good intrinsic factor in the stomach for some reason, so we assume the B12 has to be passively absorbed which is tricky. Out of 1000mcg only about 13 make it thru...the rest is lost.
It is only very recently that we have learned that this passive absorption is possible... still many doctors don't know it yet. And they don't know the new low of 400pg/ml either.
