Inhibition of β-glucuronidase in Human Urine by Ascorbic Acid

Abstract
The effects of oral supplementation of ascorbic acid (1500 mg d-1) on urinary β-glucuronidase (β-G) activity was assessed in a double-blind crossover study design over a 3-week period. The subjects on ascorbic acid treatment displayed a statistically significant (P < 0.05) decrease in β-G with an approximate decrease of 25%.
