 L-Norvaline is an analog of the amino acid L-valine. Research shows that L-norvaline is a strong inhibitor of arginase activity because of its structural similarity to ornithine, which causes a feedback regulation on the activity of arginase. When you inhibit arginase, NO is produced continuously at a higher rate in the presence of NOS and adequate L-arginine. L-arginine is the limiting factor for NO production from NOS, so inhibiting the arginase enzyme effectively increases the production of NO by as much as 60%.

L-Norvaline is an analog of the branched chain amino acid, valine. It can be found in foods

such as dairy, meat,grains, soy and peanuts. Since valine is an essential amino acid.

L-Norvaline has to be obtained through the diet, as the body cannot produce it.

It is involved in the indirect increase of nitric oxide levels in the blood. Nitric oxide has been

shown to cause relaxation in the blood vessels. This vasodilatation may help to treat heart problems and lower blood pressure. When nitric oxide production is not properly produced, an individual may have health problems such as hypertension, obesity, diabetes, heart failure, and arteriosclerosis.
