3 Data Sources : A PubMed search was completed in Clinical Queries using the key terms vitamin B 12 , cobalamin, deficiency, and treatment
Ask About the Right Schedule Some people get B12 shots weekly, others monthly
Hydroxocobalamin or Cyanocobalamin Both correct deficiency, but UK practice favours hydroxocobalamin, and for a good reason
It is also vital for fetal development and other bodily functions
Typical Dosage Range Most men with low vitamin B12 levels receive around 1,000 mcg per injection, depending on their blood levels and health goals.( 9 ) However higher doses, as much as 2,000 mcg can also be safe in some cases
The practical conclusion: for most people with mild low B12 or dietary gaps, daily methylcobalamin in a quality multivitamin is a better long-term strategy than chasing energy shots
