Glucoronolactone is a naturally occurring substance in the body that is produced in small amounts, however, for commercial use it is synthetically created. Human research is extremely limited on its use as an energy or cognitive booster, however, it is included in many types of energy drinks. Glucoronoactone may inhibit undesirable effects due to hard exercise and also may aid in the detoxification of carcinogens, however, other research suggests that it may have a synergistic effect with other food additives in producing neurobehavioral toxic effects at high doses. While glucoronlactone appears safe in normally consumed amounts, more research is needed to determine both any real benefits and any potential harms, especially for those regularly consuming energy drinks.
