B-Group Vitamins: Chemoprevention?

The author of this article hypothesizes that folic acid, vitamins B2, B6 and B12 may have an important role in the prevention of serious diseases, including cancer. Adv Clin Exp Med. 2016 May-Jun;25(3):561-568.

Comment: This is a theoretical hypothesis only, so individuals must weight hypothetical benefits vs known risks. I generally take a well rounded multivitamin daily which includes these B vitamins without megadosing.
