L-Ornithine

L-Ornithine is an amino acid that is mainly used in your urea cycle in the capacity of removing excess nitrogen from your body. It is also very important in the removal of ammonia (NH3), a waste product of cellular metabolism, from your body.

L-Ornithine is created in your body, in other words it is not an essential amino acid that you solely need from external sources. It is found in its highest concentrations in your connective tissue, for example, in your skin.

However, it is your liver cells that produce L-Ornithine from the amino acid ‘arginine’, which you take into your body and ingest from a variety of sources.

Animal protein is the best dietary source of L-Ornithine, with the top food sources for this supplement coming from meat, dairy, fish and eggs.
