The best place to inject B12 is the deltoid muscle in the upper arm.
Here are some reasons why:
- Accessibility: The deltoid muscle is easily accessible for self-injection.
- Muscle Mass: It provides sufficient muscle mass for the injection.
- Absorption: This location allows for good absorption of the vitamin B12.
However, other injection sites are also used, such as:
- The buttocks (gluteus maximus muscle): This is a common site for intramuscular injections, but it requires more skill and can be uncomfortable.
- The thigh (vastus lateralis muscle): This is another option, but it can be difficult to reach for self-injection.
It's important to consult with a healthcare professional to determine the best injection site for you. They can assess your individual needs and provide guidance on proper injection technique.
