QUESTION See Answer What precautions should you take with vitamin B12 shots
The point of loading is not to feel a repeated boost, it is to bring low levels back up to a normal range before switching to a slower schedule
See a doctor if you have high B12 and High B12 on a blood test doesnt always require action, but certain combinations warrant prompt evaluation: B12 above 1,000 pg/mL without supplementation or injections Unexplained fatigue, weight loss, abdominal pain, or night sweats alongside elevated B12 Abnormal liver function tests (ALT, AST, bilirubin) or kidney markers (creatinine, GFR) on the same panel Abnormal complete blood count (CBC), especially elevated white blood cells, red blood cells, or platelets B12 levels that are rising over serial measurements without a clear dietary or supplement explanation What to do about high B12 levels There is no specific treatment for high vitamin B12 because the B12 level itself is almost never the problem
Vitamin B12 injections can be particularly beneficial for several groups of individuals who may have difficulty obtaining adequate levels of this essential nutrient through diet alone
