My father I think has a simliar problem Tracy. He is not absorbing B12 from his foods, yet he's absorbing the other vitamins as normal.

So he has to get B12 shots every so often.

I know what you mean kako in all B vitamins being required in certain amounts to work, but some people don't absorb B12, but do absorb the rest, so they need the B12 injection to keep up with the other vitamins.

My Father reckons it has helped him, he notices more energy.
