Glucuronolactone

Glucuronolactone is a naturally occurring chemical compound produced in the human body from glucose metabolism. It is often manufactured synthetically for use in food and beverages. It is a carbohydrate derivative and is found in small amounts in some plant gums.

Glucuronolactone is sometimes added to energy drinks and other beverages, often in combination with other ingredients like caffeine and taurine. Its specific function in these products is not always clearly defined by manufacturers, but it is sometimes marketed as a performance enhancer or detoxifier.

Glucuronolactone is authorised as a food additive in the UK and is listed in the Register of Food Additive Authorisations. The European Food Safety Authority (EFSA) has evaluated glucuronolactone, and it is permitted for use in certain food categories. Scientific evidence regarding the health benefits or risks associated with consuming glucuronolactone at typical dietary levels found in energy drinks is limited and mixed, with some claims lacking robust scientific backing.
