Vitamin B12

What is it and how does it affect me?

Vitamin B12 (cobalamin) plays an essential role in red blood cell formation, cell metabolism, nerve function and the production of DNA. Metformin is a common and effective treatment for diabetes and pre-diabetes, but may lower your B12 levels. Measuring B12 can help a care provider determine if metformin is an appropriate treatment option for you or if you could benefit from B12 supplements.
