What Is Pantothenic Acid?
Also called vitamin B5, research shows it can be effective for hydration. Pantothenic acid occurs naturally in many foods (fresh meats, vegetables, and whole grains), and helps the body convert carbohydrates into glucose that we need for energy.
Oral supplementation with pantothenic acid appears to help improve breakouts, but the research on this is not substantial.
