Vitamin B12 "poisoning" shouldn't be a concern; unless you have other B12-related issues (like abnormally high levels in your bloodstream), excess B12 is removed from the body in the urine. And since you're already testing low... Well, you know.

Your body knows how much B12 it needs (which may or may not coincide with RDAs) and dispenses with the rest.
