The Prevagen hoax

If your memory is as fallible as mine is, you have probably noticed advertisements for Prevagen.

Prevagen capsules contain a synthetic version of a jellyfish protein called apoaequorin as its claimed active ingredient, plus vitamin D (just for window dressing) and several other ingredients. It is made by Quincy Bioscience, a U.S. technology company that spends heavily on slick phony anecdote-based advertising claims for Prevagen that are not backed up by science. Apoaequorin itself is not a vitamin or other nutrient that the body requires. There is no evidence that it even survives normal protein digestion once the capsule is swallowed. It's disgraceful that a fraudulent product like this evades consumer laws to be marketed with impunity.
