Each and every diabetic is prescribed with Metformin to control blood sugar.
It is also said metformin is safest anti diabetic drug.
It is also said B12 level is affected by metformin.
The exact action of metformin is not known
However metformin acts on Liver and we can see that effect in reduction of FBS.
It is also said B12 is stored in liver.(about 5 gms ??) and supplied to body in time of shortage.
is it that metformin acts by blocking some liver functions??? or it acts of circulation/recycling of B 12 and similar to B 12 what else is affected???
