Origin & History

Nutritional Profile

- High in vitamin C and antioxidants. - Contains potassium, calcium, and magnesium. - Low in calories and fat.

Reported Mechanism (Provisional)

Mechanism of Action

Yuzu's high vitamin C content (up to 150mg per 100g) enhances immune function by stimulating lymphocyte proliferation and neutrophil activity. The flavonoids hesperidin and naringin inhibit pro-inflammatory cytokines like IL-6 and TNF-α while activating antioxidant enzymes including superoxide dismutase and catalase.

Clinical Narrative (Provisional)

Limited clinical research exists specifically on yuzu supplementation. Most evidence comes from in vitro studies on yuzu flavonoids showing anti-inflammatory activity at 50-100mg doses. Small human studies on citrus flavonoids suggest potential cardiovascular benefits, but yuzu-specific clinical trials with adequate sample sizes are needed. Current evidence is preliminary and largely based on extrapolation from other citrus fruits.
