Vitamin B5, also known as pantothenic acid, is an essential water-soluble vitamin. It is vital for numerous bodily functions, playing a key role in energy metabolism, the synthesis of hormones, and the formation of red blood cells. The name "pantothenic" comes from the Greek word "pantos," meaning "everywhere," reflecting its widespread presence in various foods. As a water-soluble vitamin, B5 is not stored in significant amounts in the body, meaning a regular dietary intake is necessary for proper function (NIH Office of Dietary Supplements). Pantothenic acid is a precursor to coenzyme A (CoA), a crucial molecule involved in many biochemical reactions. It is widely available in a variety of foods, making deficiency rare in well-nourished individuals.
