    Apoaequorin: Exploring the Science

    Apoaequorin 

    In 1961 a group of researchers from Princeton University were working at Friday Harbor near Seattle, Washington. They noticed that a constant stream of glowing jellyfish floated by their lab each day and decided to study this specific species of jellyfish called Aequorea victoria to determine what caused them to glow. Led by Osamu Shimomura, PH.D, the group developed an extraction process and eventually discovered that the cause of the glowing jellyfish was a specific ingredient. Researchers began using this ingredient, apoaequorin, in many experiments. Decades of research and laboratory use then followed.

    The unique ingredient in Prevagen, apoaequorin, was evaluated for safety using a toxicity study, a common method for evaluating dietary supplements. Apoaequorin has been found to be safely consumed in amounts much higher than recommended (4,000 times the recommended daily amount of Prevagen Regular Strength).

    In a separate safety study, apoaequorin has not shown to have any significant risk of allergic reactivity when ingested.

    In a third study conducted on the safety of apoaequorin, the protocol followed was very similar to Safety Study I, however,in this instance, the amount was increased. Apoaequorin has been found to be safely consumed in amounts much higher than recommended (16,000 times the recommended daily amount of Prevagen Regular Strength).
