Nope.... do not worry. Yes, it is water soluble but it is not absorbed well. If you have intact intrinsic factor (which many people don't), it has a biological limit, and also the transcobalamin in the GI tract that takes the intrinsic factor complex with B12 from food (about 2mcg limit), into the blood stream. B12 is NOT like drugs or other things.
Studies have shown that 1000mcg of B12 ... leads to an average of 13mcg absorbed. The rest goes out thru the GI tract into the stool.
In fact the bile excretes excess B12 also into the GI tract. Some will go out the kidneys, but that is less of an issue.
Don't worry about it.
Here is my B12 thread.... the details are there.

One of the main reasons I stay on NT and donate my experience and personal time is so that people will have access to medical information, to make these decisions.
