Glucuronolactone

Glucuronolactone or Glucurolactone (INN) is a naturally occurring substance that is an important structural component of nearly all connective tissues. It is sometimes used in energy drinks. Unfounded claims that glucuronolactone can be used to reduce "brain fog" are based on research conducted on energy drinks that contain other active ingredients that have been shown to improve cognitive function, such as caffeine. Glucuronolactone is also found in many plant gums.
