Could vitamin B complex supplements be more harmful than good if taken over a period of time?

It all depends the reason why you are taking the B complex and the quality of the supplement. Many supplements contain "bad" ingredients like magnesium sterates and lactose, or just too much vitamin B. Keep in mind that you can obtain all the vitamin B you need from a healthy diet.
