Ubiquinol improves arterial health to support blood circulation

Ubiquinol significantly improves endothelial function1

In an 8-week, randomized, double-blind, placebo-controlled, single-center trial, with the primary outcome of change in flow-mediated dilation (FMD) in healthy patients with mild-to-moderate dyslipidemia, Ubiquinol significantly improved dyslipidemia-related endothelial dysfunction (P=0.001).

endothelial function

*Response with Ubiquinol was dose-independent.
No significant changes in plasma lipid profile between groups or versus baseline for either group (one-way ANOVA, P=0.905). Ubiquinol improved endothelium-dependent vasodilation independent of plasma cholesterol levels.

Flow-mediated dilation refers to a measurement of change (widening) of brachial artery diameter following an induced increase in blood flow. FMD reflects nitric oxide-mediated arterial function, and is a measure of blood vessel health.

 

Cardiovascular health is associated with many factors, including diet, lifestyle and genetics. According to a 2019 expert consensus report, each 1% increase in FMD involves a significant 8% to 13% reduction in the risk of cardiovascular events.2

Significant improvements on 3 secondary endpoints

  • Ubiquinol increased plasma CoQ10 levels versus placebo (P<0.001), and reduced the percentage of oxidized CoQ10 (P<0.001)
  • Serum NOx increased significantly in all subjects receiving Ubiquinol (P=0.016) versus placebo
  • Low-density lipoprotein (LDL) oxidation lag time improved significantly in those receiving 200 mg/day Ubiquinol (P=0.017) versus placebo

The improvement in endothelial function with Ubiquinol was positively correlated with increased NOx concentration (P=0.012) and increased LDL lag time over the course of the study (P=0.031).

Ubiquinol significantly improved endothelial function in cardiac patients with reduced ejection fraction3

In a separate small, double-blind, placebo-controlled pilot study of 14 patients with HFrEF (heart failure with reduced ejection fraction), Ubiquinol 400 mg/day for 3 months provided significant improvement in peripheral endothelial function.

  • Peripheral endothelial function was assessed using the reactive hyperemia index (RHI)
  • RHI significantly improved with Ubiquinol (P=0.026) but not with placebo (P=0.198)
