Vitamin B deficiency B2, Riboflavin.

I don't know how many of you out their have tried this, I came to this forum via a search of Toctino, a drug I study.
But the most common cause of cracked mouth corners and peeling lips is a deficiency of B2. Modern diet is very deficient in this anyway. It is the first entry in Upjohn's vitamin manual and my edition of Mercks. (old)
It's a cheap try! I would suggest double dose for a week.
Some people say this gives them bad dreams, so if this happens to you, cut down. With food, and not with water, it is easily washed out of the system. Indeed, there is a lot of thought, that it is lost from the system because of the amount of acidic sodas modern Westerners consume.
