Associating Tea Bioactivity to Cardiovascular Protection: Mechanisms and Therapeutic Potential

One of the leading causes of mortality globally, cardiovascular diseases (CVDs) are mostly brought on by lifestyle choices such as excessive blood pressure, elevated cholesterol, insulin resistance, obesity, and poor blood flow. The potential of tea and its naturally occurring components, including theaflavins, catechins, and polyphenols, to lower these risks and promote heart health has drawn more attention from scientists. This review describes the potential of tea to affect several pathways involved in cardiovascular protection. Drinking tea regularly has been associated with improved vascular function, reduced oxidative stress, and better cholesterol levels, all of which support normal blood pressure management. Additionally, tea improves metabolic management by boosting insulin sensitivity and stabilizing blood sugar levels. Evidence of enhanced energy utilisation, higher fat metabolism, and hormonal balance pertaining to hunger and fat storage supports its involvement in weight management. Tea may also help reduce tissue damage caused by oxygen and blood flow restriction, a common problem in heart disease. Taken together, the evidence suggests that tea can serve as a simple, natural addition to a heart-conscious lifestyle. More clinical studies are necessary to confirm long-term benefits, but current findings are promising for cardiovascular support and prevention.
