I want to take a Vitamin B supplement with my Metformin in a liquid supplement. Is that ok?
Studies have shown that metformin can impair vitamin B12 absorption, which in turn, may lead to B12 deficiency. Vitamin B12 can be taken orally (pills or liquid) or by an injection. Before you start taking a supplement, however, I’d advise you to check with your healthcare provider. He or she may want to check your blood level of B12 in order to determine an appropriate dose for you.
