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
