Roll Call does not check drug interactions or assess personal safety.
A small molecule the body produces naturally in modest amounts as part of glucose metabolism, and which is also manufactured for use as a supplement ingredient.
Why it’s used
Included in some energy drinks and supplement blends, typically alongside caffeine and taurine, in products marketed for alertness or energy.
What the evidence says
There is little independent research isolating glucuronolactone's effects from the caffeine and taurine it is usually paired with, so its own contribution to any reported effect is unclear.

"Glucuronolactone"[Title/Abstract]
This says what this database holds under these terms. It is not a finding that no research exists.
Context
Most studies involving glucuronolactone examine multi-ingredient energy drink formulas rather than the compound on its own, making it difficult to attribute any observed effect specifically to it.
