I have been using Shaklee products and sharing them for over 25 years. They have the utmost integrity and have helped countless people improve their health and financial wellness. Many companies say they are proven but Shaklee has the research to back up their products . I never worry about quality or safety as they test their sources and the completed products to make sure they are safe and that they work! I don’t know of any other company that goes to that length. Quite honestly nothing compares and Dr. Shaklee understood the importance of nature long before anyone else, a true visionary!
