too many vitamins?

I've been having awful dry and cracking and bleeding lips for months now... I read it may be due to a lack of vitamin B and to take vitamin B complex.. i'm already taking a multivitamin recommended by my doctor... will it be harmful to take vitamin B also?

Hezzer: B vitamins are water-soluable  and your body will just get rid of what it does not use, do not to worry about too many Bs. Cant answer your question about C0Qten.  D
