Vitamin B5, also called pantothenic acid, is one of 8 B vitamins. All B vitamins help the body convert food (carbohydrates) into fuel (glucose), which the body uses to produce energy. These B vitamins, often referred to as B complex vitamins, also help the body use fats and protein.It's important for many functions in the body, especially making and breaking down fats.
According to one study, after eight weeks of treatment, volunteers with acne who took a daily oral dose of a dietary supplement containing pantothenic acid experienced a 50% decrease in acne.
Doctors consider vitamin B5 safe at doses equal to the daily intake, and at moderately higher doses. Very high doses may cause diarrhea and may increase the risk of bleeding. Pregnant and breastfeeding women should not exceed the daily adequate intake unless directed by their doctor.
