Water soluble α‐glycosylated rutin (4G‐α‐D‐glucopyranosyl rutin, monoglucosyl rutin, MR) was used in this study to evaluate its ability to reduce abdominal visceral fat (AVF). We conducted a study examining 66 healthy Japanese men and women with a body mass index of ≥23 and <30 kg/m² for 8 weeks. The subjects were randomly assigned to groups via computer random numbers as follows: MR200 group (MR 200 mg/day), MR400 group (MR 400mg/day), or placebo group. The primary outcome was change in the AVF area after 8 weeks of intervention. The secondary outcomes were effects of MR on total fat and subcutaneous fat of umbilical area, lipid‐related markers, and subjective symptoms. The per‐protocol set analysis involved 18 subjects in the placebo group (7 males and 11 females), 20 subjects in the MR200 group (8 males and 12 females), and 20 subjects in the MR400 group (8 males and 12 females). AVF area in both the MR200 and MR400 groups was reduced at week 8, with changes from the baseline (week 0) significantly higher than the placebo group. Additionally, the MR400 group reported improved subjective symptoms concerning being “worried about abdominal fat” at week 4 compared with the placebo group. These results indicate that the consumption of MR (200 and 400 mg/day) for 8 weeks reduced AVF. PRACTICAL APPLICATION: Monoglucosyl rutin, an enzymatically modified form of rutin, is a highly stable and water‐soluble flavonoid widely used in food and beverages to prevent oxidation. The present clinical study demonstrated that it may improve overall health by reducing abdominal visceral fat.
