What is D-Glucuronolactone?

D-Glucuronolactone is a naturally occurring glucose metabolite found in the body and in some foods. It is commonly added to energy drinks and marketed for detox and energy support.

What does D-Glucuronolactone do in the body?

It can serve as a precursor in glucuronidation, a normal liver-related process that helps the body process and eliminate certain substances. This role does not necessarily translate into noticeable benefits for healthy people.

Does D-Glucuronolactone boost energy or reduce fatigue?

It is often included in energy drinks, but any perceived energy effects are usually hard to separate from other ingredients like caffeine. Evidence for clear benefits from D-Glucuronolactone alone is limited.

What is a typical dosage of D-Glucuronolactone?

Common supplemental amounts are often in the range of about 500–1200 mg. Individual needs and tolerance can vary, especially when taken with other stimulants.

Is D-Glucuronolactone safe?

It is generally used in supplements and energy drinks, but safety can depend on the total product formula and your health status. If you are pregnant, breastfeeding, have liver or kidney disease, or take medications, consult a clinician before use.

D-Glucuronolactone

Limited research available·3/10

A higher score indicates better study conditions, but not necessarily effectiveness.

A naturally occurring compound sometimes included in energy drinks, D-Glucuronolactone may support liver detoxification and energy metabolism but lacks robust evidence for clinical benefits in healthy adults.

dose range

500–1200 mg

Often taken in divided doses or within energy drink servings.

Consumption

Best taken as part of a beverage or supplement, ideally with or after food.

Not fat-soluble.

Best time

Most commonly consumed in the morning or before exercise as part of an energy supplement.

Description

D-Glucuronolactone is a glucose metabolite present in connective tissue and various foods, often promoted in energy drinks for detoxification and energy support.
