Rated 5 out of 5 by Amps up your Nitric Acid I've used this product for many years and Swansons has the BEST! Both amino acids work in concert with each other boosting your nitric acid in the bloodstream. L-Arginine is the main ingredient in all of the nitric acid drinks on the market, but the encapsulated powder is WAY more economical with the EXACT same benefits! I've promoted this Swanson product for years. April 14, 2013
Rated 5 out of 5 by Muscle builder I have used the Arginine for a year, made some very good gains in muscle bulk... just went to this formula, am hoping for even better results... supposed to help as an anti-age thing too... but since I have always been a great looking guy... who knows??? :-) February 5, 2013
