Although our body has the ability to make L-Arginine‚ it may be important for many of us to also take a supplement. L-Arginine is extremely important for many body functions and is usually only naturally present in low quantities. L-Arginine is a precursor of nitric oxide‚ which is necessary for the healthy dilation of blood vessels‚ circulation‚ and blood flow. Because of this‚ L-Arginine also supports a healthy immune system and athletic performance. Each teaspoon provides 3 g of L-Arginine.

      Can help with Blood Clots.

      from MO on 12/29/2015
      L-Arginine Powder by Carlson Labs was recommended to me by a friend. She takes it because of high risk for clotting. Since so many deaths can be attributed to blood clots I thought I would try it. Come to find out this amino acid is so important with so many functions of the body. I will continue to take it....even tho the taste is not very pleasant. The brand is trusted too!


      It's a powder.... I take to many capsules already.


      The taste is unpleasant.
