For over 40 years, Nature Made has been a leader in formulating and manufacturing a wide array of nutritional supplements that help people of all ages live a healthy life. They use scientific research to ensure reliability and effectiveness, use only the highest-quality raw materials, and live up to their goal of transparency by having easy-to-understand labels that clearly state the ingredients and amounts in each supplement. Nature Made was the first brand of vitamins to have products certified by the United States Pharmacopeia (USP), indicating that it meets stringent standards for bioavailability and safety. PureFormulas is proud to offer Nature Made products, which are made in a United States-based facility.
