4,5 Dietary insufficiency, pernicious anemia (i.e., an autoimmune process that reduces available intrinsic factor and subsequent absorption of vitamin B 12 1,2,6,7 ), and long-term use of metformin or acid-suppressing medications have been implicated in B 12 deficiency
It is therefore possible to be B12 deficient despite having high B12 blood levels for example, if the vitamin cannot correctly bind to transport molecules (6)
Injections bypass the gastrointestinal tract and are the standard treatment for pernicious anaemia and severe deficiency in the UK
Why Get Vitamin Injections One of the reasons we love vitamin injections is because they have better absorption since they are are delivered directly into the bloodstream
Some practices may require periodic review appointments to assess injection technique and monitor treatment response
