Source Naturals L Arginine L Citrulline Complex

an important factor in muscle metabolism and a precursor for nitric oxide, which promotes increased circulation by relaxing blood vessels. L-Citrulline helps the body rid itself of ammonia, a by-product of exercise. This clearing enables the body to recover after a workout. Features of Source Naturals L Arginine L Citrulline Complex  Free-form amino acid combination. Arginine supports muscle metabolism, energy, heart function, and circulation. Arginine easily converts into nitric oxide (NO).  l-Arginine/l-Citrullinne Complex supports liver detoxification l-Arginine and l-Citrulline are two amino acids bundled into a single powerful supplement. Both are key intermediates in the Krebs urea cycle, where they participate in the detoxification of ammonia via the production of urea.  The formation of NO mediates smooth muscle relaxation in the blood vessel wall, and thus reduces the workload of the heart.
