Contact your healthcare provider if you notice any unusual reactions or side effects
Some patients feel as though they want more frequent injections, and occasionally we test levels to see if they are receiving adequate replacement, but Im not sure how strong the evidence is to support this. GPs should consider periodic vitamin B12 testing of higher-risk patients who take metformin, even if they dont display symptoms of deficiency, the UK medicines regulator said earlier this year
Since your body naturally does not make vitamin B12 on its own, you will have to take it from another source like animal-based foods, pill supplements, or injections
Assessing vitamin B12 absorption and bioavailability: Read the label
B12 is an essential vitamin that plays an important role in making DNA, maintaining nerve health, and producing red blood cells
I would encourage patients to speak to their practice if they have concerns about their B12 treatment
