Glycerin, also called glyercine or glycerol, is a nutrient sold as a supplement for use in food, as a treatment for constipation and on the skin. Manufacturers add glycerin to protein bars because when taken with water, it facilitates "hyperhydration," according to the Supplement Research Foundation. It is sweet, clear and odorless. Glyercin is classified as a carbohydrate by the FDA.
