Effects of Oral Sodium Butyrate Supplementation on Body Weight Reduction in Overweight/Obese Individuals With and Without Type 2 Diabetes
In Brief
A clinical study evaluating Sodium Butyrate (NaBut) and Placebo for Obesity and Type 2 Diabetes. Completed, enrolled 46 participants across 1 site.
Detailed Summary
The goal of this clinical trial (randomized controlled trial with parallel group design) is to evaluate the effects of oral sodium butyrate supplementation for 12 weeks, compared with placebo, in addition to a moderately hypocaloric diet, on body weight, body composition, glucose metabolism, and lipid metabolism in overweight or obese individuals with and without type 2 diabetes. The main questions this study aims to answer are: * Does oral sodium butyrate improve body weight reduction and body composition compared with placebo? * Does it improve glucose and lipid metabolism in participants with and without type 2 diabetes? The study includes 46 men and women aged 30-70 years, with overweight or obesity (BMI 25-39.9 kg/m²) and HbA1c ≤ 7.0%. Participants are randomly assigned to receive either oral sodium butyrate or placebo, both combined with a moderately hypocaloric diet for 12 weeks. Participants: * Take sodium butyrate tablets (625 mg three times daily; total 1,875 mg/day) or placebo tablets with meals * Follow a personalized, balanced hypocaloric diet monitored by a dietitian * Attend clinic visits every two weeks for anthropometric measurements and dietary adherence checks * Complete a 7-day food diary and a gastrointestinal symptom questionnaire (PAGI-SYM) * Undergo fasting blood tests, body composition analysis (bioelectrical impedance), and continuous glucose monitoring (CGM) at baseline and after 12 weeks

Timeline
Interventions
Participants receive oral sodium butyrate (NaBut) in combination with a moderately hypocaloric diet for 12 weeks. Sodium butyrate is administered as 625 mg tablets (Butir Bioma®, UNIFARCO S.p.A.), taken three times daily with meals (breakfast, lunch, and dinner), for a total daily dose of 1,875 mg. The hypocaloric diet is individualized based on basal metabolic rate (measured by indirect calorimetry) and physical activity level, with a 300-500 kcal/day energy reduction.
Participants receive placebo tablets identical in appearance, weight, shape, color, smell, and taste to the sodium butyrate tablets but without the active ingredient, combined with the same moderately hypocaloric diet as the experimental group. Tablets are taken three times daily with meals (breakfast, lunch, and dinner), for a total of three tablets per day. The hypocaloric diet follows the same composition and energy restriction as described for the sodium butyrate intervention.
