nhs vitamin b12 injections BSH guidance on during Covid-19 changed can my doctor give me

If you check these labs and see that your MCV is greater than 92 and that your homocysteine is greater than 10.0 there is a HIGH chance that your B12 levels are NOT optimized

B12 shots supply vitamin B12 as methylcobalamin or cyanocobalamin, typically given intramuscularly into the deltoid, supporting red blood cell formation, myelin and nervous system health, and the metabolism of homocysteine, a process that can falter with vegan diets, malabsorption, or medications like metformin

Similarly, taking B12 supplements is unlikely to prevent cell damage caused by nitrous oxide use
