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 effect of pyridoxine hydrochloride supplementation on anthropometric indices, body composition, visceral adiposity index (VAI), and metabolic status in obese and overweight women. In this randomized controlled clinical trial, 44 obese and overweight women aged 18–50 years were selected and divided randomly into 2 groups: an intervention group (receiving 80 mg pyridoxine hydrochloride supplement for 8 weeks) and a control group (receiving placebo for 8 weeks). In the pyridoxine hydrochloride group, weight (p = 0.03), body mass index (p = 0.023), fat mass (p = 0.003), waist circumference (p = 0.005), VAI (p = 0.001), fasting insulin, insulin resistance (homeostasis model assessment of insulin resistance; HOMA-IR), total cholesterol, low-density lipoprotein, 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, VAI, fasting insulin, HOMA-IR, and TG between pyridoxine hydrochloride and control groups following intervention in adjusted models (p < 0.05). The findings suggest that vitamin B6 supplementation may be effective in reducing BMI and improving body composition and biochemical factors associated with obesity.
