Cholesterol-Lowering Nutraceuticals Affecting Vascular Function and Cardiovascular Disease Risk

Area of Science:

• Cardiovascular Research
• Nutritional Science
• Pharmacology

Background:

• Dietary supplements, or nutraceuticals, are increasingly explored for their potential cardiovascular benefits.
• Understanding the efficacy of cholesterol-lowering nutraceuticals on vascular function and cardiovascular (CV) risk is crucial for clinical application.
• Current research highlights a varied landscape of evidence regarding their impact on lipid profiles and vascular health.

Purpose of the Study:

• To review and update the evidence on cholesterol-lowering nutraceuticals and their combinations.
• To assess the effects of these nutraceuticals on vascular function and CV risk in clinical studies.
• To identify nutraceuticals with demonstrated cholesterol-lowering and vascular protective properties.

Main Methods:

• Systematic review of clinical interventional studies.
• Analysis of data on cholesterol-lowering efficacy.
• Evaluation of evidence for vascular protective effects and impact on CV outcomes.

Main Results:

• Red yeast rice, berberine, plant sterols, and fibers demonstrate mild-to-moderate cholesterol-lowering effects.
• Some nutraceuticals show promising vascular protective effects, but CV outcome data is limited, except for red yeast rice.
• Few single nutraceuticals and combinations provide evidence for both cholesterol reduction and vascular protection.

Conclusions:

• Certain nutraceuticals offer potential benefits for cholesterol management and vascular health.
• Further clinical trials are necessary to confirm the impact of these supplements on hard cardiovascular outcomes.
• Caution is advised regarding the widespread, uncontrolled use of these freely available products due to potential misuse.
