Nature's Plus is a brand with over 25 years of unwavering commitment to quality and meticulous attention to detail. Nature's Plus state-of-the-art manufacturing facility in Melville, New York is held to the highest standard of supplement industry GMP (Good Manufacturing Practice). The building has controlled airflow and temperature, and dust collection; and all personnel wear protective clothing to protect from cross contamination. Both raw materials and final products are extensively tested for quality and purity. Before full production, a preliminary batch of 500 tablets or capsules is made and immediately analyzed for weight variation, disintegration, friability, hardness, thickness, organoleptic characteristics and compliance with USP (United States Pharmacopoeia) and NF (National Formulary) specifications. Every year as an unbiased proof of quality and potency, Nature's Plus publishes the results of analysis by an independent testing lab.
