What customer service can help with

Call to enroll in the 5-hour course, to ask about the petition process when your organization is not on the published list, or to sort out access to a subscription you already bought. A 5-year subscription, as described on the course page, includes future revisions of that course.

If a lesson will not open, also see course system requirements. The player is built for a tablet, a PC, or a Mac. Have the course id ready when you call.

We do not publish an email address for this catalog. Phone is the contact method. Do not send card numbers, passwords, or photos of your credit card to any address you find elsewhere and assume it belongs to this site. Enrollment is a phone conversation with customer service.

What this site cannot answer

Calls about a personal medical diet, a diagnosed condition, or a supplement dose should go to a registered dietitian or a physician. The guides on this website explain the science behind the course. They are not a consult, and customer service does not write meal plans. If your question is whether your certifying board will accept the hours, ask the board, and use customer service only for the completion record the course provides.

For how this site handles cookies and advertising, read the privacy policy. For the devices the lesson player supports, read course system requirements. The course outline and price are on The Science of Nutrition.
