Dr. Marc Sorenson, EdD
Founder, The Sunlight Institute
mSorenson@sunlightInstitute.org


Health education expert Dr. Marc Sorenson has become one of North America's leading independent sunlight and vitamin D advocates, traveling throughout the United States and Canada to deliver the message that vitamin D deficiency is killing people and that sun avoidance is unwarranted. Sorenson is the author of "Vitamin D3 and Solar Power for Optimal Health" (http://www.vitaminddoc.com) - a book detailing the benefits of vitamin D produced naturally through sun exposure. Sorenson is a regular sun tanner and believes that the benefits of regular non-burning sun exposure outweigh the risks associated with overexposure, which can be minimized by avoiding sunburn.

A health education expert, Sorenson founded the National Institute of Fitness as one of the top health resorts in the world, helping clients lose a total of 110 tons of fat and helping two-thirds of his diabetic guests become symptom-free and off of medication. His book Megahealth was a top-seller and was a Book of the Month selection by Doubleday’s Health Book Club.
