Prevagen

Prevagen appears in Why is there a supplement craze if they don’t even work? as the episode’s main case study in supplement regulation. The source describes it as a memory supplement associated with a synthetic lab-made version of a jellyfish-linked protein, tied in the story to Mark Underwood and his mother’s multiple sclerosis question.

The case matters because it combines several layers of the wiki’s new supplement branch. The episode says the FDA questioned safety, the company used NeuroShake and GRAS Self-Certification to support use of the ingredient, people reported serious side effects while taking the supplement, and the FTC eventually won a false-advertising case after years of sales.
