Vitamin B12

Along with B9, Vitamin B12 is necessary for DNA synthesis, which in turn  is necessary for the creation of new nerve cells. Vitamin B12 can be found in foods such as meat, fish, sardines and dairy products and also synthetically produced. It is often taken in combination with other B vitamins.
