The potential benefits of supplemental nutrients and dietary interventions against cardiovascular morbidity and mortality have been extensively investigated throughout the years. Numerous supplements claim cardioprotection and reduction of cardiovascular risk factors, but the roles of many supplements have not been determined. In the vast number of supplements on the market asserting cardioprotective effects, only 3 have been thoroughly evaluated and consistently reported as effective by our clinic patients. They have used supplements such as fish oil, multivitamins, and calcium, but many had not known of the benefits of resveratrol, curcumin, and nitric oxide as supplements for improving cardiovascular health. The cardioprotective effects of these dietary supplements in both animal models and humans have been explored with proposed mechanisms of action mostly attributed to antioxidant and anti-inflammatory properties. Resveratrol is one of the most studied polyphenols with established cardiovascular benefits. Preclinical studies have demonstrated these effects exerted via improved inflammatory markers, atherogenic profile, glucose metabolism, and endothelial function and are further supported by clinical trials. Curcumin has a well-established anti-inflammatory role by regulating numerous transcription factors and cytokines linked to inflammation. Inflammation is an underlying pathology in cardiovascular diseases, rendering curcumin a potential therapeutic compound. Similarly, nitric oxide supplementation has demonstrated cardiovascular benefits by normalizing blood pressure; enhancing blood flow; and reducing inflammation, immune dysfunction, and oxidative stress. A comprehensive review was performed evaluating the cardioprotective effects of these 3 dietary supplements with hope to provide updated information, promote further awareness of these supplements, and inspire future studies on their effects on cardiovascular health.
