Doctor’s Best L Citrulline

Doctor’s Best L-Citrulline servings: 66 Serv Citrulline is a non-essential amino acid that is an important intermediate in the urea cycle, functioning along with Arginine and Ornithine to rid the body of ammonia, a byproduct of protein metabolism. Because Citrulline is a precursor of Arginine, it provides a readily available source material for Arginine production, which in turn, can be used for the production of Nitric Oxide (NO). NO plays a fundamental role in vascular function and blood flow. Citrulline therefore, not only supports cleansing pathways, but also supports NO production and a healthy cardiovascular system. Directions Take 1 scoop daily with 8 oz. of water or beverage of your choice, before workouts, or as recommended by a nutritionally-informed physician.
