High-dose oral therapy (10002000 micrograms daily) can be effective even in pernicious anaemia, as approximately 1% of B12 is absorbed through passive diffusion independent of intrinsic factor
However, this amount may be slightly higher for certain groups, including people who are pregnant or breastfeeding
Supplementing with B12 often erases these symptoms
Therefore, receiving a B12 injection can help alleviate symptoms associated with B12 deficiency, such as fatigue, weakness, and cognitive impairment
We offer one-on-one support to walk you through your injection, plus detailed instructions on how to inject correctly
otherwise, high-dose oral B12 (1,0002,000 mcg/day) usually works just as well
