What supplements have evidence for supporting endothelial function?

L-citrulline, cocoa flavanols, resveratrol, and beetroot extract have clinical evidence for improving flow-mediated dilation (FMD), a measure of endothelial function. Vitamin C and curcumin have also shown endothelial benefits in some studies. These supplements may support the nitric oxide pathway critical for vascular health.

Can supplements alone reverse endothelial dysfunction?

While some supplements improve endothelial function markers in clinical trials, addressing underlying causes is essential. Smoking cessation, regular aerobic exercise, Mediterranean diet, weight management, and controlling blood pressure, cholesterol, and blood sugar are the most effective interventions for restoring endothelial health.

When should someone with endothelial dysfunction see a doctor?

Endothelial dysfunction is an early marker of cardiovascular disease. If identified through vascular testing, work with a healthcare provider to address cardiovascular risk factors comprehensively. Endothelial dysfunction may precede clinical cardiovascular events by years, making it an opportunity for early intervention with proven medical strategies.

Common Symptoms

Usually asymptomatic (subclinical) Reduced exercise tolerance Erectile dysfunction Impaired wound healing

Risk Factors

Smoking
Diabetes
Hypertension
Dyslipidemia
Aging
Obesity
Physical inactivity
Oxidative stress
