Dietary Supplements and Cardiovascular Diseases

Area of Science:

• Nutritional Science
• Cardiovascular Medicine
• Public Health

Background:

• The global nutritional supplement market is expanding, driven by health consciousness and an aging population.
• Cardiovascular diseases (CVDs) remain a leading cause of mortality in developed nations.
• Despite widespread supplement use, consensus on their cardiovascular benefits is lacking.

Purpose of the Study:

• To review and synthesize current research on the association between dietary supplements and cardiovascular risk.
• To highlight novel insights and areas of ongoing investigation regarding supplement efficacy for CVD.

Main Methods:

• Literature review and synthesis of existing studies on dietary supplements and cardiovascular outcomes.
• Focus on commonly used supplements such as multivitamins, Vitamin D, Coenzyme Q10 (CoQ10), and probiotics.
• Analysis of challenges in studying supplement effects, including confounding lifestyle factors and limited randomized trials.

Main Results:

• Multivitamins are suggested to reduce cardiovascular events.
• Vitamin D levels correlate with coronary artery disease, heart failure, and atrial fibrillation.
• Coenzyme Q10 (CoQ10) deficiency is linked to myocardial dysfunction and statin myopathy.
• Probiotics show potential in lowering blood pressure and lipid levels.

Conclusions:

• The relationship between dietary supplements and cardiovascular health is complex and requires further investigation.
• Confounding factors, such as healthier lifestyles among supplement users, complicate research findings.
• More rigorous, randomized studies are needed to establish definitive links between specific supplements and CVD prevention or management.
