Abstract
Background:
Metabolic syndrome (MetS) is a cluster of central obesity, hypertension, hyperglycemia, and dyslipidemia. It is a global health issue with an increased risk of cardiovascular disease. Recently, a few natural products have been reported with promising anti-inflammatory and antioxidative effects. We aimed to evaluate the impact of δ-tocotrienol and resveratrol mixture (TRM) supplementation on cardiometabolic risk factors and biomarkers in patients with MetS.
Methods:
A randomized controlled trial was conducted at the hospitals of National University of Medical Sciences Rawalpindi, Pakistan. A total of 82 patients with MetS aged 18–60 years were enrolled based on International Diabetes Federation-2005 diagnostic criteria and randomly grouped into TRM (n = 41) and placebo (n = 41). Patients in the TRM group were given a 400 mg capsule (δ-tocotrienol 250 mg; resveratrol 150 mg), and a placebo (cellulose 400 mg) twice daily for 24 weeks. The biochemical tests were analyzed on ADVIA 1800 Chemistry® analyzer and inflammatory biomarkers by ELISA methods.
Results:
In the TRM group, a significant reduction in waist circumference, blood pressure, mean (95% confidence interval) of fasting plasma glucose −0.15 mmol/L (−0.22 to −0.08), serum triglyceride −0.32 mmol/L (−0.47 to −0.17), and increment in high-density lipoprotein cholesterol were observed as compared with placebo. TRM supplementation also improved biomarkers: high-sensitive C-reactive protein −0.61 mg/L (−0.89 to −0.33), interleukin-6-1.99 pg/mL (−2.50 to −1.48), tumor necrosis factor-α −2.19 pg/mL (−2.55 to −1.83), malondialdehyde −0.48 μmol/L (−0.65 to −0.30), and total antioxidant capacity 1.71 U/mL (1.29 to 2.13).
Conclusion:
TRM supplementations improved cardiometabolic risk factors and biomarkers of inflammation and oxidative stress without any significant side effects in the patients with MetS.
