menaquinone-6 and Dyslipidemias

Dietary supplementation with sugar cane derivates may modulate low-density lipoprotein cholesterol (LDL-C) and proprotein convertase subtilisin/kexin type 9 (PCSK9) levels. The purpose of this study was to determine if dietary supplement (DS), containing Octacosanol (20 mg) and vitamin K2 (45 µg), could restore the disrupted physiologic relation between LDL-C and serum PCSK9. Double-blind, randomized, placebo-controlled, single-center study including 87 patients on chronic atorvastatin therapy was conducted. Eighty-seven patients were randomized to receive DS (

This work investigated the impact of vitamin K2 and selenium co-supplementation on metabolic profile and indicators of cardiovascular health in dyslipidemic rabbits. Fifty adult male rabbits were equally allocated into 5 groups: Control group, Dyslipidemic group: received 0.5% cholesterol in diet for 12 weeks, groups 3, 4 and 5 dyslipidemic rabbits daily treated with vitamin K2 (10 mg/kg bw) or/and selenium (1 mg/kg bw) for 8 weeks. Co-supplementation of vitamin K2 and selenium significantly decreased body weight gain and blood pressure elevation in dyslipidemic rabbits compared to un-treated ones. Consuming vitamin K2 plus selenium also markedly lowered serum lipids encompassing cholesterol, triglycerides and LDL and elevated HDL relative to placebo. Additionally, such co-supplementation reduced fasting glucose and insulin, enhancing insulin sensitivity with respect to placebo. Regarding cardiovascular risk markers, dyslipidemic rabbits received vitamin K2 concurrently with selenium displayed lower levels of atherogenic index (LDL/HDL), serum C-reactive protein, heart fatty acid-binding protein and asymmetric dimethylarginine as well as aortic ox-LDL, lipid peroxidation and calcium but higher levels of serum nitric oxide and aortic total antioxidants than un-treated ones. Concomitant administration of vitamin K2 and selenium improved metabolic profile, markers of cardiovascular health and atherosclerosis in dyslipidemic rabbits.

Epidemiological outburst of type 2 diabetes is of great global concern. T2D starts with Insulin Resistance (IR) which arises largely due to environmental factors and to a lesser extent due to genetic factor. IR gradually develops into T2D and encompasses a wide array of conditions including Impaired Glucose Tolerance (IGT), hyperinsulinemia, Impaired Fasting Glucose (IFG), and Impaired Insulin Release (IIR). Initiation of IR increases the risk of Cardiovascular Diseases (CVD). Therefore, early diagnosis and management of IR and its related outcomes (hyperinsulinemia, hyperglycemia, and dyslipidemia) should be the prime focus of intervention therapies. Present research aimed to evaluate the synergistic combination of Magnesium orotate (MOD), Menaquinone- 7 (MK-7), and Cholecalciferol (CHOL) for the management of these therapeutic targets in the Streptozotocin-Nicotinamide-induced T2D Wistar rat model. Synergistic combination was found to be superior over its individual components in management of hyperglycemia, impaired insulin secretion, Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), and dyslipidemia (p < 0.01 or p < 0.05). Its effect was found to be equivalent or better than reference drugs (p < 0.01 or p < 0.05). Histopathological analysis depicted that combination treatment was able to regenerate and preserve pancreatic β-cell mass in diabetic rats. In conclusion, combination studied in present research can be evaluated further under clinical settings for management of IR and its related outcomes.
