Why is this so important? Sales of these special brands must be sold through a health care practitioner like us because we can help you choose the best ones for your specific needs. Not to mention that when you find them on Amazon, they are often counterfeits from China or expired! Plus, there is no one to support you if you have questions about how to take them for example.  But through us, you are guaranteed to get the authentic supplements made by the companies you love, plus you get our support.
