vitamin b12 1000 mcg injection Compounded Cyanocobalamin (Vitamin B12) 12 solution to be administered through injection only Intended for use in cats CYANOCOBALAMIN INJECTION, USP 10,000mcg/10mL (1,000mcg/mL)

Now, lets take a closer look at what Vitamin B12 shots are all about

IM B12 injection is especially appropriate when oral supplementation has been inadequate, when absorption is compromised, or when neurological symptoms are present (Stabler, New England Journal of Medicine , 2013)

When your stomach empties more slowly and produces less acid, B12 absorption drops

Dose cycling Some long-term users cycle between doses

The body can only absorb approximately 1.5 g per dose through the intrinsic factor mechanism, which is why higher doses rely on passive diffusion for additional absorption
