I haven’t heard of ‘apoaequorin’ before?

Researchers sure have! Apoaequorin (Pronounced: ā-poe-ē-kwôr-ĭn) was discovered in the early 1960’s when scientists wondered why a certain species of jellyfish glowed in the Puget Sound (Washington state). They discovered that when the protein apoaequorin, contained in the jellyfish, bound to calcium, a light was emitted. Today, because of apoaequorin’s long-history and safety, it is a preferred research tool. Don’t worry though, glowing is not a side-effect with Prevagen!

What are all the asterisks (*) for?

The asterisk (*) denotes the FDA disclaimer for dietary supplements. This statement or “disclaimer” is required by law (DSHEA) when a manufacturer makes a structure/function claim on a dietary supplement label. In general, these claims describe the role of a nutrient or dietary ingredient intended to affect the structure or function of the body. The manufacturer is responsible for ensuring the accuracy and truthfulness of these claims; they are not approved by FDA. For this reason, the law says that if a dietary supplement label includes such a claim, it must state in a “disclaimer” that FDA has not evaluated this claim. The disclaimer must also state that this product is not intended to “diagnose, treat, cure or prevent any disease,” because only a drug can legally make such a claim.
