Directions When you buy Vitamin B12 injections your pharmacist will provide you with printed instructions you can reference before giving yourself the injection
Vitamin B12 is a water-soluble vitamin that supports: Red blood cell production Nervous system function DNA synthesis Energy metabolism B12 injections deliver this essential nutrient directly into the bloodstream, bypassing absorption issues that come with oral supplements

If you would prefer to start out with sublingual forms and oral B12 then I recommend this supplement
