L-Arginine is not in the list of ingredients.
Go to[...] for a list of ingredients for this product L-Arginine was not in the list.  or Google the Cardio SupportTM and find arc-nutrition.  This product may have had L-Arginine in it at one time but it doesn't look like it does anymore.  It would be a serious over site to not include 5000 mg of L-Arginine on the list of ingredients.  If you are looking for a true L-Arginine product for NO - Nitric Oxide production to help with blood pressure and circulation do your homework.  I would find a product with L-Arginine & L-Citrulline in it they seem to need to work together from what I've read.
