Quality Assurance Standards

Quality assurance standards are critically important if you want your nutritional supplement to consistently deliver results. It’s one of the reasons why we’ve chosen ProArgi-9+ from Synergy Worldwide to properly nourish your endothelium for improved nitric oxide production.

SWSynergy Worldwide is a wholly owned subsidiary of Nature’s Sunshine Products (NSP), an industry giant founded in 1972.  NSP scientists worked with Synergy and Dr. J. Joseph Prendergast to oversee the design, manufacturing, and production of ProArgi-9+ utilizing quality-control mechanisms comparable to those used in the pharmaceutical industry.

ProArgi-9+ was introduced to the market in 2008. A total of 262 quality assurance steps go into the manufacturing of this product. It’s one of the reason why many consider ProArgi-9+ to be “The Best Nitric Oxide Supplement” in the marketplace. Additionally, it’s one of the few nutritional supplements with a Quality and Potency Guarantee.
