Source Naturals L-Arginine L-Citrulline Complx 120 Tablets

Product Label

L-Arginine and L-Citrulline are two amino acids bundled into a single powerful supplement. L-Arginine is an important factor in muscle metabolism and is 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.


1 tablet four times daily.


If you are pregnant, may become pregnant, or are breastfeeding, have a history of heart disease, hypotension, renal or hepatic failure, or are taking any prescription medications such as nitroglycerine or any drugs for erectile dysfunction, consult your physician prior to using this product. Not recommended following acute myocardial infarction.

      Comments about Source Naturals L-Arginine L-Citrulline Complx - 120 Tablets:

      I buy this product for my 90 year old mother to help with her memory problems in addition to these two amino acids improving the flow of blood in her veins. I've done a lot of research in the holistic field, and have found this product, which has the combination of the two amino acids, to be the best on the market. She takes it 4 times a day, and the biggest added bonus of her taking it is that it naturally lowers her blood pressure, allowing the doctor to stop prescribing high blood pressure pills. All in all, it is a great supplement, but please do your own research first to see if it would be advantageous for your own physical situation. Good Luck!

        Been taking the product for awhile so I'm used to what it does. But, it does work. Two fold product: a. helps to circulate blood flow better so more oxygen gets through the blood stream b. helps recover from a workout faster. Indirect side effect is increased sexual satisfaction but you must workout. This is not a magic pill but it does help. Take as directed. I would take a week off from them after bout a month, just to give your body a rest. Add LongJax when needed and its a party!

          A Vitamin Shoppe customer asked: is this the best product in the family of Nitric Ozide? Mar 16, 2014
          Answer this · Send to friends Good question? Yes (0) No (0)
          Jorge C: Hi there,
          I think this is a very suitable formula in the family since it combines l-arginine + L-citrulline. L-Argeinine alone is scarcely absorbed in the digestive trackt, but the citrulline combination enhances it. As a matter of fact, citrulline inhibits an enzime which neutralises arginine in the stomach, hence it is fully absorbed. You will feel it during workout. You'll get an evident muscle congestion which will last long after workout.

          John B: I purchased this mainly because of the ingredient L-citrulline, as it is a proprietary component of a leading commerical NO supplement. In combination with L-arginine it should enable nitric oxide production. Mar 18, 2014
          Reply to John Good answer? Yes (0) No (0)
          james F: I like it because citrulline turns into arginine in your body over the course of the day. Mar 17, 2014

          Jack C: Yes, the best I have tried. Mar 19, 2014
