Flavonoids, a class of polyphenolic compounds commonly found in various fruits, vegetables, and beverages, have garnered significant attention due to their potential cardiovascular health benefits. These bioactive molecules are known for their anti-inflammatory, antioxidant, and vasodilatory properties, making them promising candidates for managing cardiovascular diseases. This paper aims to evaluate the phytopharmacological properties of flavonoid-rich extracts, focusing on their effects on heart disease parameters such as blood pressure, cholesterol levels, oxidative stress, and endothelial function. A comprehensive review of in vitro, in vivo, and clinical studies was conducted to assess the efficacy and mechanisms of flavonoid extracts in cardiovascular health management. The results indicate that flavonoid-rich extracts have the potential to improve cardiovascular health by lowering blood pressure, reducing LDL cholesterol, enhancing endothelial function, and mitigating oxidative stress. Furthermore, the bioavailability of these compounds and their ability to interact with key molecular pathways, such as nitric oxide synthesis and cholesterol metabolism, were also explored. Despite promising findings, the translation of these bench-side results into clinical practice remains a challenge, particularly regarding standardized dosages, formulations, and long-term safety. This review highlights the potential of flavonoid-rich extracts as a complementary approach in cardiovascular disease prevention and therapy. Further research, particularly large-scale clinical trials and exploration of optimal delivery methods, is essential to fully realize their therapeutic potential in clinical settings
