Description Description: 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 detoxification pathways, but also supports NO production and a healthy cardiovascular system.The Inside Scoop: Contains no: sugar, salt, yeast, wheat, gluten, soy, milk, egg, shellfish or preservatives.Nutrition Facts: Serving Size (Capsules) 2 Servings Per 45 L-Citrulline 1.5g Ingredient Details: Gelatin (capsule), Calcium Carbonate, Magnesium Oxide and Magnesium Stearate (vegetable source).Suggested Use: As a dietary supplement, take 1-2 capsules 1 to 2 times daily between meals.Warnings: Store in a cool, dry place.
