Arginine, citrulline, and ornithine are amino acids with distinct roles in the body. Arginine serves as a precursor to nitric oxide, impacting blood vessel dilation and supporting various bodily functions. Citrulline is involved in the urea cycle, indirectly contributing to nitric oxide production, making it a popular supplement for enhancing exercise performance and reducing muscle soreness. Ornithine, also part of the urea cycle, aids in detoxification and is used in supplements to potentially support athletic performance. Together, these amino acids are sometimes combined as dietary supplements to promote nitric oxide production, potentially improving blood flow and exercise capacity, but it's advisable to consult a healthcare professional before using such supplements.
