Your body uses it for a few important jobs: Making red blood cells, which carry oxygen and keep your energy up Turning the food you eat into usable energy, which supports your metabolism Keeping your nerves healthy and preventing tingling or numbness Supporting mood, focus, and mental clarity A shot delivers B12 straight into the muscle and bloodstream, so it skips the digestive system entirely
Vitamin b12 is also called cobalamin
Patients are advised to report any unusual numbness, tingling, or coordination problems, as these may signal neurotoxicity if dosing is excessive
It is also important to consult with a healthcare provider before starting B12 shots, especially for those on medications that may interfere with B12 absorption or metabolism
