      What is Citrulline?

      Citrulline is a classified nonessential amino acid that is neither a component of any major proteins or enzymes. It provides for processes related to the production of energy in the body, and is responsible for the proper functioning of the immune system. Because of the nonessential nature of citrulline, it may not need to be consistently ingested from any dietary sources. Citrulline is a very unusual amino acid. A variety of biological and chemical reactions define citrulline. This amino acid is formed in the urea cycle with the addition of carbon dioxide, forming ornithine. The process continues as ornithine is combined with aspartic acid to form arginosuccinic acid, which is then further metabolized to the most humanly bioavailable form, L-arginine. This critical transformation, of citrulline to arginine, is fundamental for maintaining the homeostasis of certain toxicities within the body. Arginine itself is a key component in the formation of urea in the liver. The process of removing nitrogen metabolites from the body are directly dependent upon citrulline's conversion to arginine. Citrulline, aspartic acid, citric acid, and magnesium work synergistically to remove excessive nitrogen build-up, and aid in the digestion, absorption, and metabolic processes of specific proteins.

      What are the benefits of taking Citrulline?

      Citrulline has been shown to relax blood vessels, improve blood flow and raise overall nitric oxide levels. Many bodybuilders take citrulline with their pre and post workout drinks to help improve recovery, increase vascularity and improve muscle pumps throughout the day and following a training session.

      One study found 5,600mg of citrulline daily for 7 days in healthy men was able to improve blood flow secondary to nitric oxide. The improvement in blood flow was correlated with the serum increases in arginine.

      Recommended dose:

      3000-8000mg taken 60 minutes before exercise

      Does Citrulline have any side effects?
