It's essential to undergo a comprehensive health evaluation to determine the appropriate regimen tailored to your specific requirements

In clinic settings, emergency measures (like epinephrine and antihistamines) should be readily available in the rare event of an allergic reaction

For example, if your body is incapable of absorbing and/or storing optimal amounts of B12, you may be recommended to have injections as frequently as every one or two weeks

In conditions such as Crohn's, celiac disease, or pernicious anemia, the gut cannot absorb B12 from food well
