Mark Underwood

Mark Underwood appears in Why is there a supplement craze if they don’t even work? through the origin story of Prevagen. The episode connects his idea to his mother, who had multiple sclerosis and wondered whether jellyfish might hold a medical breakthrough.

The wiki treats Underwood as part of the source’s case narrative rather than as an independent authority. His story helps explain why a product can begin with a personal health hope, then become a mass-market supplement shaped by Dietary Supplement Regulation, GRAS Self-Certification, and later Federal Trade Commission advertising enforcement.
