Aequorin is a calcium-activated photoprotein isolated from the hydrozoan Aequorea victoria. Though the bioluminescence was studied decades before, the protein was isolated in 1962 from the animal by Osamu Shimomura. In the animals, the protein occurs together with the green fluorescent protein to produce green light by resonant energy transfer, while aequorin by itself generates blue light. Discussions of "jellyfish DNA" to make "glowing" animals often refer to transgenic animals that express th In human clinical trials, apoaequorin was well tolerated for up to 90 days. 11 In animal safety studies, apoaequorin was found to be safely consumed in doses much higher than the recommended dosage (4000 to 16,000 times the recommended daily amount of Prevagen Regular Strength) and without adverse effects when taken orally.

Apoaequorin has been found to be safely consumed in doses much higher than recommended dosage (4,000 times the recommended daily amount of Prevagen Regular Strength). View The Summary Apoaequorin has been shown in laboratory studies to support neuronal cells (4), (5). Based on in vitro and in vivo animal studies (4), (5), (6), (7), we hypothesized that apoaequorin has the potential to enhance memory and cognitive function in healthy, non-demented individuals, results from humans. Previous work with apoaequorin in aged 2018-02-07 Apoaequorin has been shown in laboratory studies to support neuronal cells. Based on in vitro and in vivo animal studies, we hypothesized that apoaequorin has the potential to enhance memory and cognitive function in humans. Previous work with apoaequorin in aged canines demonstrated cognitive enhancement.

• The primary ingredient in Prevagen is a synthetic version of apoaequorin, a protein originally derived from certain jellyfish. The Prevagen researchers hypothesize that, by regulating levels of intracellular calcium, “apoaequorin has the potential to improve the function of aging neurons and, therefore, to enhance memory and cognitive function.” But because the company manufactures a synthetic form of apoaequorin, the supplement is a drug, the FDA says. As a drug, the company must perform studies to show it is both effective and safe, and the company must follow drug labeling and marketing regulations. Answer From Jonathan Graff-Radford, M.D. Phosphatidylserine (fos-fuh-tie-dul-SER-een) is a dietary supplement that has received some interest as a potential treatment for Alzheimer's disease and other memory problems. Several studies with phosphatidylserine indicate improved cognitive abilities and behaviors.

The results indicated a strong relationship between apoaequorin and improvements on a quantitative measure of cognitive function, specifically verbal learning.
