If you need guidelines, or plan on injecting B-12 into your belly area, here’s how to do it.

Well, injecting into the belly area is a simple and basically painless procedure, so it isn’t much to worry about in that regard. Just follow the correct steps and you’ll do just fine. The Abdomen is an easy place for most people to access when self-injecting vitamin B-12, which is why it is a very common area for B-12 injections. The name for the method of injecting into the belly (abdomen) area is subcutaneous injection. It is named that because the B12 is delivered into the fat below your skin and above your muscle. See example image.

Where to inject in your belly

Doctors and nurses recommend injecting in any fatty area at least 2 inches (5cm) from your belly button, even further out into your love handles is fine.

Just penetrate into the fat (we all have some) below your skin so that your body can absorb the vitamin B12 and you will begin to quickly feel its benefits over the next 24hrs.


Needles and syringes can be found through the links on our site, at your local pharmacies or with a quick internet search.

Most people choose a small gauge needle such as 27 and a 1/2” needle with a 1-2ml syringe. Most insulin needles come with a 1ml syringe and ½ inch needle attached, which makes ordering, using and disposing quite easy.

Always dispose of your needles into a clearly marked ‘sharps container’. This avoids any potential accidents and protects our environment when taken to proper disposal sites.
