Abstract
Background and Objectives: Obesity has reached epidemic proportions globally. Among several methods for treating obesity, the use of dietary supplements is common recently. One supplement that can help in this regard might be vitamin B6 in high doses.The objective of this study was to evaluate the efficacy of pyridoxine hydrochloride supplementation on anthropometric measurements, body composition, visceral adiposity index and metabolic status in obese and overweight women.Methods and Study Design: In this randomized controlled clinical trial, 44 obese and overweight women aged 18–50 years were selected and divided randomly into two groups: an intervention group (receiving 80 mg pyridoxine hydrochloride supplement for 8 weeks) and control group (receiving placebo for 8 weeks). Results: In the pyridoxine hydrochloride group, weight(p=0.01), body mass index(p=0.009), fat mass(p=0.003), waist circumference(p=0.005), visceral adiposity index(p=0.001), fasting insulin, Insulin Resistance(HOMA-IR), Total cholesterol, low density lipoprotein(LDL), Triglycerides (TG) and leptin(p<0.001) decreased whereas adiponectin(p<0.001) increased in comparison to the baseline values. There was a significant difference in fat mass, visceral adiposity index, fasting insulin, HOMA-IR and TG between pyridoxine hydrochloride and control groups following intervention in adjusted models(p<0.05).Conclusions: The findings suggest that vitamin B6 supplementation may be effective in reducing BMI and improving body composition and biochemical factors associated with obesity.Trial registration: Iran Clinical Trials Registry: IRCT20181002041206N1.
