L-arginine supplements have been gaining popularity in recent years for their potential benefits in promoting heart health. L-arginine is an amino acid that helps the body produce nitric oxide, which can help improve blood flow and reduce inflammation in the arteries. Studies have shown that L-arginine supplements may help lower blood pressure, improve cholesterol levels, and reduce the risk of cardiovascular disease. These supplements are available in various forms, including pills, powders, and drinks. However, it is important to consult with a healthcare professional before taking L-arginine supplements, especially if you have a history of heart disease or are taking medication.
