A member asked:

Ive been taking methyl b12 supplements (1500mcg) a day since april. from july, i switched to 1000mcg. didnt get tested for deficiency. ive always had acne before my period even after puberty but its now worse. could b12 be causing acne?

A doctor has provided 1 answer

High, unneeded doses of vitamin B12 don't have side effects and the superfluous amounts of B12 are harmlessly passed out in the urine. A dermatologist can counsel you on causes of acne or factors that aggravate it.
