Vitamin B5, or pantothenic acid, performs a number of functions within the body. It helps to synthesize cholesterol, produce red blood cells, and generate energy. Because of these functions, it provides a number of health benefits, from improved skin and hair to a reduction of fatigue. Pantothenic acid helps to regulate the hormones that impact mood. Increasing Vitamin B5 intake may help alleviate symptoms related to stress, anxiety, and depression.

Because Vitamin B5 plays a role in cholesterol synthesis, it also helps to keep cholesterol and blood pressure levels healthy. Vitamin B5 helps to break down carbohydrates, proteins, and fats so that they can be converted into energy. This improves overall energy levels and physical stamina, which makes this vitamin a necessity for particularly active individuals. Vitamin B5 also prevents physical signs of aging, improves immune health, and may enhance the body's supply of hemoglobin.
