BERBERINE SUPPLEMENTATIONS (Berberine)
EFFECTS OF BARBERRY (BERBERIS VULGARIS) SUPPLEMENTATIONS ON ANTIOXIDANT AND OKSIDANT CAPASITY IN HEALTHY ADULTS
This randomized, placebo-controlled interventional study aims to evaluate the effects of 60 days of supplementation with a liposomal Berberis vulgaris-based product on antioxidant status, selected biochemical parameters, body weight, body mass index (BMI), and body composition in healthy adult volunteers. The planned total enrollment is 40 participants. The intervention group will receive one 200 mg capsule daily for 60 days, subject to confirmation of the product's composition and labeling. The comparator group will receive a placebo according to the approved study protocol. Total antioxidant capacity (TAC), total oxidant status (TOS), and other prespecified outcomes will be assessed using the methods and time points defined in the protocol.

Descrizione dettagliata
At baseline, participants who meet the inclusion and exclusion criteria and provide written informed consent will undergo anthropometric measurements, including body weight, height, and body composition, at the Healthy Nutrition Counseling Unit of the Faculty of Health Sciences, Sivas Cumhuriyet University. Medical history and demographic information will also be collected using a personal information form. Blood samples will be collected at the Biochemistry Laboratory of Sivas Cumhuriyet University Hospital to assess routine biochemical parameters, including glucose, insulin, renal and liver function markers, lipid profile, electrolytes, and uric acid. Blood results will be evaluated by a study physician. During the 60-day supplementation period, participants will be contacted by telephone every 15 days. Dietary intake will be assessed using 24-hour dietary recalls, and appetite status will be evaluated using the Simplified Nutrition and Appetite Questionnaire. Adherence to the intervention will be monitored through these calls and verified at the end of the study by checking the returned supplement packages and unused capsules. At baseline and at the end of the study, blood samples will also be analyzed for total antioxidant capacity (TAC), total oxidant status (TOS), paraoxonase-1 (PON1), and arylesterase (ARE) activities. Serum samples will be separated by centrifugation and stored at -80°C until analysis. TAC and TOS will be assessed as the primary outcome measures, while PON1 and ARE activities will provide additional information on enzymatic antioxidant defense. These measurements will enable a comprehensive evaluation of the effects of Berberis vulgaris supplementation on oxidative balance and antioxidant defense.
