Abstract

Objective Although several experimental models have suggested promising pharmacological effects of naringenin in the management of obesity and its related disorders, the effects of naringenin supplementation on cardiovascular disorders as one of the main complications of nonalcoholic fatty liver disease (NAFLD) are yet to be examined in humans. Methods In this double-blind, placebo-controlled, randomized clinical trial, 44 overweight/obese patients with NAFLD were equally allocated into either naringenin or placebo group for 4 weeks. Cardiovascular risk factors including atherogenic factors, hematological indices, obesity-related parameters, blood pressure, and heart rate were assessed pre- and postintervention. Results The atherogenic index of plasma value, serum non-HDL-C levels as well as total cholesterol/high-density lipoprotein cholesterol (HDL-C), triglyceride/HDL-C, low-density lipoprotein cholesterol/HDL-C, and non-HDL-C/HDL-C ratios were significantly reduced in the intervention group, compared to the placebo group post intervention (P < 0.05). Moreover, there was a significant reduction in BMI and visceral fat level in the intervention group when compared with the placebo group (P = 0.001 and P = 0.039, respectively). Furthermore, naringenin supplementation could marginally reduce systolic blood pressure (P = 0.055). Mean corpuscular hemoglobin increased significantly in the naringenin group compared to the placebo group at the endpoint (P = 0.023). Supplementation with naringenin also resulted in a marginally significant increase in the mean corpuscular hemoglobin concentration when compared with the placebo group (P = 0.050). There were no significant between-group differences for other study outcomes post intervention. Conclusion In conclusion, these data indicate that naringenin supplementation may be a promising treatment strategy for cardiovascular complications among NAFLD patients. However, further trials are warranted. © 2022 Lippincott Williams and Wilkins. All rights reserved.
