The Health Store and the Bookstore portions of our website provide links to purchase products that are manufactured by other parties. It is important to us that you understand that these parties compensate us for referrals and provide us with the product information that is used on our site for your convenience. We encourage you to visit each party’s website directly for further information about any product in our Bookstore that interests you. Orders from this bookstore for Dr. Northrup’s products are processed by Amazon.
