'''B vitamins''' are a class of water-soluble [[vitamin]]s that play important roles in [[Cell (biology)|cell]] [[metabolism]] and synthesis of [[red blood cell]]s.<ref name=NIH>{{cite web|publisher=Office of Dietary Supplements, US [[National Institutes of Health]]|title=Folate - Fact Sheet for Health Professionals|url=http://ods.od.nih.gov/factsheets/folate/|date=29 March 2021|accessdate=29 April 2022}}</ref> Though these vitamins share similar names (B<sub>1</sub>, B<sub>2</sub>, B<sub>3</sub>, etc.), they are [[chemical]]ly distinct compounds that often coexist in the same foods.<ref name=NIH/> In general, [[dietary supplement]]s containing all eight are referred to as a '''vitamin B complex'''. Individual B vitamin supplements are referred to by the specific number or name of each vitamin, such as B<sub>1</sub> for thiamine, B<sub>2</sub> for riboflavin, and B<sub>3</sub> for niacin.<ref name=NIH/> Some are more commonly recognized by name than by number, for example pantothenic acid, biotin, and folate. It's a really cool vitamin.
 
Each B vitamin is either a [[cofactor (biochemistry)|cofactor]] (generally a [[cofactor (biochemistry)|coenzyme]]) for key [[metabolism|metabolic]] processes or is a [[precursor (chemistry)|precursor]] needed to make one.<ref name=NIH/>
