Abstract

Background: It has been observed that mitochondrial dysfunction is associated with an increased risk of metabolic syndrome. There is growing evidence that hyperactivity of the hypothalamus-pituitary-adrenal (HPA) axis and hormone (testosterone and growth hormone) deficiency may lead to metabolic syndrome. Recent studies have reported that ginseng treatment improves mitochondrial and HPA-axis function and increases anabolic hormone secretion. Objectives: The objective of this study was to investigate the effect of red ginseng (RG) on metabolic syndrome, hormones, and mitochondrial function using leukocyte mitochondrial DNA copy number in men with metabolic syndrome. Methods: We performed a randomized, double-blind, placebo-controlled study in 62 subjects who were not taking drugs that could affect their metabolic function. A total of 62 men with metabolic syndrome were randomly assigned to either an RG group (3.0 g/day) or a placebo group for 4 weeks. We analyzed changes in metabolic syndrome components, leukocyte mitochondrial DNA copy number, hormones (total testosterone, IGF-1, cortisol, and DHEAS) and inflammatory markers (C-reactive protein, ferritin) from baseline to 4 weeks. Results: Significant improvement in mitochondrial function (95% CI -44.9 to -1.3) and an increase in total testosterone (95% CI -70.1 to -1.0) and IGF-1(P = 0.01) levels were observed in the RG group when compared with the placebo group. Diastolic blood pressure (95% CI 2.0-9.4) and serum cortisol (95% CI 1.1-5.5) significantly decreased in the RG group. Conclusions: We found evidence that RG had a favorable effect on mitochondrial function and hormones in men with metabolic syndrome.
