Arginine AKA L-Arginine is a conditional amino acid meaning it’s produced by our body. When taken as a supplement, it can help with things like migraine and inflammation. But what does Arginine actually do to your body? It boosts Nitric Oxide levels which stimulate the blood vessels’ inner walls and dilates them to allow more blood to flow freely. In other words, it relaxes blood vessels and can be pretty good for your heart and wider cardiovascular system.
