L-arginine is a unique amino acid that your body partially produces on its own but also relies on dietary sources. You can find it in various protein-rich foods like meat, poultry, fish, eggs, dairy products, nuts, seeds, and legumes. It reduces blood pressure, enhances blood flow, boosts the immune system, and improves exercise performance. Plus, this amino acid influences sexual health by increasing blood flow to the genitals, relaxing blood vessels, and boosting erectile function.
L-citrulline, a non-essential amino acid, occurs naturally in the body and in certain foods like watermelon, pumpkin, and cucumbers. The body converts l-citrulline into l-arginine, which then becomes nitric oxide. Nitric oxide has various vital functions, including widening blood vessels, enhancing blood flow, and supporting muscle function. Studies demonstrate L-citrulline’s benefits for sexual health, with improvements in erectile function, libido, and reduced fatigue.
