No, you can only buy Kidney Prime right here. The Amazon marketplace is cluttered with inferior quality kidney supplements that muddy the waters and make it harder for people to find formulas that work. We feel it is important to sell Kidney Prime on our own website, only, because this enables us to share far more information than Amazon would ever allow. This is crucial because information is the key to kidney health. Our site is more than Kidney Prime; it is a valuable resource for anyone with kidney concerns… whether they are interested in Kidney Prime or not. Kidney health is best achieved with a holistic approach that includes lifestyle, diet, stress management, and more. Amazon is just a store. www.kidneycoach.com gives you resources that can do so much more.
