B vitamin complex

B vitamin complex is a nutritional supplement containing a variety of different B vitamins.

ME/CFS
A small study of chronic fatigue syndrome patients found below normal levels of a number of B vitamins, including vitamin B6 (pyridoxine), B1 (thiamine), B2 (riboflavin) and folic acid, these levels were unlikely to be caused by deficiencies in diet. Vitamin B6 levels were particularly low.
