What it is

Glucuronolactone is a naturally occurring compound found in the human body and in some plant gums. It is often produced commercially through the oxidation of glucose.

Why it's used

Glucuronolactone is commonly added to energy drinks and other beverages, where it is marketed as a "detoxifier" or performance enhancer. Its exact functional role in these products is not always clear, but it is sometimes used as a flavor enhancer or to contribute to the overall beverage profile.

Health notes

Glucuronolactone is generally recognized as safe (GRAS) by the FDA for use in food. JECFA (Joint FAO/WHO Expert Committee on Food Additives) has evaluated glucuronolactone and did not set a numeric limit (ADI not specified). While often promoted for health benefits in energy drinks, scientific evidence supporting these claims at typical consumption levels is limited and mixed. Some studies suggest potential benefits for fatigue or cognitive function, but more research is needed.

Allergen info

Glucuronolactone is not derived from any of the nine FDA major allergens. It does not contain gluten.
