Raspberry ketone is a chemical from red raspberries (Rubus idaeus). It is most commonly used for weight loss and obesity. It is also used to increase lean body mass. Some people apply raspberry ketone to the scalp to improve hair growth. Raspberry ketone is also used in foods, cosmetics, and other manufacturing as a fragrance or flavoring agent.
Raspberry ketone became popular for weight loss after it was mentioned on the Dr. Oz television show during the segment called “Raspberry ketone: Miracle fat-burner in a bottle” in February 2012.
