smoking + vitamin b12
Cyanide in cigarette smoke binds to active forms of vitamin B12 (methylcobalamin and hydroxocobalamin), converting them to the inactive cyanocobalamin form which is excreted, and chronic smoking damages the gastric mucosa, reducing intrinsic factor production and B12 absorption.
