Sodium butyrate aids weight, glucose
A proof‑of‑concept randomized trial published in Clinical Nutrition found oral sodium butyrate helped with weight loss and blood‑glucose control in overweight/obese adults with and without type 2 diabetes. It’s early-phase work — promising mechanistic signal via gut‑derived short‑chain fatty acids, but larger trials are needed. x.com/HealthyFellow/status/2032292444507947191
The trial was run at the University of Naples “Federico II,” with Giuseppina Costabile listed as the responsible party, and the report is available as a Clinical Nutrition pre‑proof (March 2026). clinicaltrials.gov The study is registered as NCT07252609 and used a randomized, parallel‑group design that enrolled 46 adults aged 30–70 years with BMI 25.0–39.9 kg/m² and HbA1c ≤7.0%. clinicaltrials.gov Intervention details in the registry specify oral sodium butyrate 625 mg taken three times daily (1,875 mg/day) for 12 weeks, delivered alongside a personalized moderately hypocaloric diet. clinicaltrials.gov Planned endpoints and measurements included body composition by bioelectrical impedance, fasting blood panels, continuous glucose monitoring (CGM), 7‑day food diaries, and the PAGI‑SYM gastrointestinal symptom questionnaire. clinicaltrials.gov The record lists study start on November 13, 2024 and primary/completion dates of August 8, 2025, and the modest sample size (n=46) plus exclusion of insulin‑treated patients are explicit limitations for power and generalizability. clinicaltrials.gov Comparable human work includes a 2024 ADA abstract of 52 people with type 2 diabetes using microencapsulated butyrate 1.5 g/day for 12 weeks (which reported GI‑symptom relief and small BMI/HbA1c changes) and the Federico II group’s earlier BAPO pediatric obesity RCT published in JAMA Network Open. diabetesjournals.org Authors and recent reviews note the need for larger, longer, multicenter trials to validate mechanisms, dose, and safety in diverse populations, a recommendation reiterated by a 2025 literature review on sodium butyrate in type 2 diabetes. mdpi.com
