Sea Buckthorn Aqueous Infusion Impact

* A total of 60 overweight women (BMI 25-29.9 kg/m²), aged 18-50years, will be enrolled and randomized equally into intervention and control groups. The intervention group will consume a 5 g freshly prepared seabuckthorn aqueous infusion daily for 12 weeks, while controls maintain usual habits without supplementation. * The seabuckthorn aqueous infusion will be prepared by using 250mL of potable boiled water and then cooled to a lukewarm temperature (around 40-45°C). At this point, 5 g of seabuckthorn powder will be added, stirred thoroughly until fully dispersed, and consumed immediately. The infusion will be freshly prepared once daily and administered in the morning after breakfast. Measurements will be conducted using the InBody 270, a validated bioelectrical impedance analyzer employed in this study to obtain accurate assessments of body weight, body mass index (BMI), waist-hip ratio, and visceral fat levels. The device offers segmental analysis and visceral fat estimation through non-invasive, standardized procedures, ensuring consistency and reliability in longitudinal tracking.
