When you are giving a B12 injection subcutaneously, you pinch the fat to make sure youre only penetrating the subcutaneous tissue (or the innermost layer of skin) and pull it away from the muscle, then insert the needle

A deficiency can also result from not getting enough B12 in what you eat due to various food restrictions

The body's preferred, natural form of B12

A subcutaneous injection uses a shorter needle to inject the B12 solution into the tissue layer between the skin and muscle, but it may be a slower absorption rate than other methods of administration
