NSP scientists visit our herb growers and vendors to examine their fields and check their harvesting and cleaning techniques. We test raw materials and product batches in our labs for purity and potency. We even keep samples on hand for future testing needs should they arise.
Our 260,000 square-foot, pharmaceutical-grade manufacturing facility features state-of-the-art bin mixers and packaging lines that can produce over 15 million capsules per day. That space includes our Quality Assurance labs and environmentally designed warehouse. NSP spent $21 million expanding and upgrading our facility in 2001.
NSP is the first health supplement company to use a Gas Chromatography/Mass Spectrometry/MS Triple Quad. It detects impurities down to parts per TRILLION…with a T. We also have four Ph.D.s on staff
