B12 Injections: The Direct Delivery Method Vitamin B12 injections deliver the nutrient directly into muscle tissue, bypassing the digestive system entirely
It acts as a selective inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme expressed in multiple tissues including adipose tissue and the liver that plays a role in cellular energy metabolism and fat storage
If you are severely deficient, then in three months of daily injecting all of your old, sick red blood cells will have expired, and be replaced by healthy ones
These shots are typically quick and easy to administer, and they can benefit individuals who have difficulty absorbing B12 from food or supplements
Contraindications Given the limited safety data, conservative contraindications would include pregnancy or plans to become pregnant, breastfeeding, age under 18, severe liver or kidney disease, and any condition requiring medications with unknown interaction potential
Once youre ready, a skilled provider will clean the injection site typically the upper arm and use a fine needle to administer the shot
