Glucuronolactone is a small molecule that contributes to the structure of connective tissues. It is an important precursor of ascorbic acid (Vitamin C) synthesis and detoxicant. Glucuronolactone combines with toxic substances and converts them into water-soluble conjugates that can be excreted in urine. It may have hepatoprotective effects in this capacity.
Glucuronolactone is commonly used in energy drinks due to its detoxification effects. Combining glucuronolactone with other substances such as caffeine can improve performance, particularly on tasks that require large amounts of focus and attention.
