Beta-hydroxybutyrate is a chemical that is made by the body to provide energy in times when not enough carbohydrates or sugars have been eaten. Beta-hydroxybutyrate can also be made in the lab and taken as a supplement.

Beta-hydroxybutyrate is placed in the eye for dry eye and taken by mouth for athletic performance, migraine, Alzheimer disease, memory loss with age, Parkinson disease, and many other conditions, but there is no good scientific evidence to support these uses.
