What should I do if my B12 level is high
Well cover how to give Vitamin B12 shots, including how to measure the dose, where to inject, and how to do it yourself

This is a serious risk
Who is more likely to have low B12 Vegetarians and vegans, since B12 comes mainly from animal foods Adults over 50, because absorption naturally declines with age People with gut conditions such as celiac, Crohn, or past GI surgery Long-term users of metformin or acid-reducing medications People who have had weight-loss (bariatric) surgery Those with heavy or frequent alcohol use If you see yourself in that list, a simple blood test is the logical next step
This ensures the B12 remains in the muscle for steady release rather than being dispersed too quickly
