Since lipotropic injections are a mixture of amino acids and B-vitamins, they are completely safe when administered as directed in proper dosages via injection
These injections are typically administered intramuscularly , although some protocols allow for MIC B12 injections to be administered subcutaneously or intramuscularly , depending on clinical preference
However, a very small percentage of B12 from a supplemental dose is absorbed by passive diffusion, rather than by intrinsic factor, such that vegans can make up for taking B12 only once per day, or even only once per week, by taking larger doses than normally provided by food
The choice of how to give the injection depends on the patients health, the desired effect, and the doctors opinion
