The goal of this clinical trial is to learn if a traditional grape-based fermented drink called hardaliye helps treat fibromyalgia in adult women. We will also learn whether adding hardaliye to a personalized nutrition plan works better than using either one alone. The main questions are: Does diet + hardaliye improve antioxidant status and lower oxidative stress more than diet only or hardaliye only? Does diet + hardaliye lower inflammation (TNF-α, IL-6, hs-CRP) and raise SIRT1 levels? Do these changes relate to less pain and better symptoms (fibromyalgia impact, gut symptoms, sleep, mood)? Are there benefits for weight, waist size, blood pressure, and blood lipids? How the groups are compared: Researchers will compare three groups for 8 weeks: Diet + Hardaliye (personalized medical nutrition plan + one 200 mL bottle of hardaliye daily) Diet only (personalized medical nutrition plan) Hardaliye only (usual diet + one 200 mL bottle of hardaliye daily) Participants will: Drink one 200 mL bottle of hardaliye each day if assigned to Diet + Hardaliye or Hardaliye only Follow a personalized nutrition plan if assigned to Diet + Hardaliye or Diet only Visit the clinic at the start and end of the study, with brief check-ins around weeks 2, 4, and 6 Give blood samples before and after the 8-week period Complete short questionnaires on pain, fibromyalgia impact, gut symptoms, sleep, and mood Keep simple logs of daily drink intake and diet plan adherence, and report any side effects Who can join: Adult women (20-40 years) with doctor-diagnosed fibromyalgia and BMI 25.0-29.9 kg/m² who meet the study's health and medication criteria.
