As far as professors go, the course offers the best of the best. World-renowned doctors, dietitians, and experts the likes of Mark Hyman, M.D., and Robin Berzin, M.D., will be your instructors over the self-paced journey. Students typically complete the training in eight to 10 weeks and then take an additional week or more to prepare for their final exam, but you can take it at your own pace. Once you graduate, you’ll still have lifetime access to all online lessons and 660+ pages of in-depth study guides—as well as an ever-growing alumni network.
