L-Norvaline - Glossary

L-Norvaline

An analog of the amino acid valine. L-Norvaline is an (in-vitro) inhibitor of the arginase enzyme, which breaks arginine down to ornithine and urea.  Thus, L-norvaline is sometimes added to NO (nitric oxide) supplements as a “nitric oxide amplifier,” on the theory that inhibiting arginine breakdown can will enhance NO synthesis.
