L-Arginine (1600 mg 3.53 oz)

L-Arginine is a crystalline free-form amino acid. It is an important factor in muscle metabolism and works to transport store and excrete nitrogen. It is a precursor for nitric oxide which promotes increased circulation by relaxing blood vessels.

L-Arginine is an amino acid that is present in proteins. It helps to detoxify the ammonia in the body which is formed during the breakdown of muscle. It also helps to reduce catabolism by maintaining nitrogen balance

Suggested Use:1/2 teaspoon daily between meals.
