{{Short description|Group of vitamins}}

'''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. They are a [[chemical]]ly diverse class of compounds, but are associated in [[Diet (nutrition)|diet]], often occurring together in the same foods. [[Dietary supplement]]s containing all eight are referred to as a '''vitamin B complex'''. Individual B vitamins are referred to by B-number or by chemical name, such as B₁ for thiamine, B₂ for riboflavin, and B₃ for niacin, while some are more commonly recognized by name than by number, such as pantothenic acid (B₅), biotin (B₇), and folate (B₉).
