                                Over 40% of the US population may have suboptimal B12 levels, leading many to consider injections for treatment. However, selecting the correct needle to use for B12 injection is crucial for ensuring proper absorption, maximizing effectiveness, and minimizing discomfort. A needle that is too short or too thin may lead to poor absorption, while one that is too long can cause unnecessary pain.
