B12 injections can begin working within hours or a few days

When you swallow a B12 pill, several steps have to work for it to be absorbed: stomach acid and the enzyme pepsin must release B12 from food or the supplement, the stomach must secrete a protein called intrinsic factor that binds to B12, and the B12-intrinsic factor complex must reach the ileum (the end of the small intestine) where it is finally absorbed

High-dose oral B12 (1,000 to 2,000 mcg daily) can actually correct deficiency even in some people with poor absorption, because a small percentage of B12 is absorbed passively (without intrinsic factor)

Its chosen because it effectively fixes vitamin B12 deficiency in most adults
