There are nearly 100,000 natural products in the U.S. Many of these products are not regulated or monitored to the extent that we feel is appropriate. We strongly recommend to use supplements ONLY after consulting with knowledgeable healthcare provider first. As part of our commitment to high quality care we have researched each individual supplement that is placed into our store. We obtain our supplements from highly reputable manufacturers; some of these do not sell their products directly to consumers because of high concentrations of nutrients that can cause harm if taken without medical supervision.
