Lipid-lowering nutraceuticals update on scientific evidence

Area of Science:

• Cardiovascular Medicine
• Nutraceutical Science
• Pharmacology

Background:

• Cardiovascular diseases (CVDs) are the leading global cause of mortality.
• Key risk factors include modifiable elements like smoking, hypertension, diabetes, and hypercholesterolemia.
• Elevated total cholesterol (TC) and low-density lipoprotein-cholesterol (LDL-C) are central to coronary heart disease (CHD) development.

Purpose of the Study:

• To explore the role of lipid-lowering nutraceuticals in managing dyslipidemia.
• To assess their potential use alongside or as an alternative to conventional therapies.
• To review their mechanisms of action and vascular effects.

Main Methods:

• Review of existing literature on lipid-lowering nutraceuticals.
• Classification of nutraceuticals based on their cholesterol-modulating mechanisms.
• Analysis of clinical evidence regarding efficacy and tolerability.

Main Results:

• Nutraceuticals can inhibit cholesterol absorption, hepatic synthesis, or enhance LDL-C excretion.
• They show promise for individuals with borderline lipid profiles or drug intolerance.
• Many nutraceuticals exhibit vascular benefits, including improved endothelial function and antioxidant properties.

Conclusions:

• Nutraceuticals can be a valuable adjunct or alternative for specific patient groups, particularly those intolerant to statins.
• They are not a substitute for standard lipid-lowering treatments in high-risk CVD patients.
• Further research may elucidate optimal use and combined therapeutic strategies.
