L-Ornithine is a non-proteinogenic amino acid. Foodstuffs such as the freshwater clam, enoki mushroom and cheese contain high L-ornithine. L-Ornithine is also included in the human liver. It is one of the components of the urea cycle, a process involved with the detoxification of ammonia. (as L-ornithine-L-aspartate).
