Doctors typically inject Vitamin B12 either intramuscularly or subcutaneously, depending on the best course of treatment.
According to research, intramuscular injections are often preferred because they deliver the medicine directly into the muscle, allowing for immediate absorption into the surrounding tissues, which can lead to better results.
- Intramuscular (IM) injections: These are administered directly into a muscle.
- Subcutaneous (SC) injections: These are given into the fatty tissue just beneath the skin.
