Shaklee is the oldest and most successful nutritional products company in America. At a time when the public didn't know what vitamins and minerals were, Dr. Shaklee (in 1915) created his first product called Vitalized Minerals! Forty years later, Shaklee became a U.S. corporation and produced the first biodegradable household cleaners. For 100 years, Shaklee has offered the best nutritional, personal care and biodegradable home products in the world. All products are 100% gauranteed; so, if you are not satisfied, you can return them for a 100% refund or replacement.
