Dose

100 mg Nobiletin twice daily

Participants

80 adults with metabolic syndrome

Duration

12 weeks

Results

Nobiletin significantly improved fasting glucose (−9%), triglycerides (−14%), and waist circumference. HDL cholesterol increased. Adiponectin elevated and resistin reduced compared to placebo group.
