Prevagen Review - 12 Things You Need to Know

Very few products get as much attention as memory and brain supplements, and Prevagen is one of those. Prevagen claims to be “the top-selling memory supplement in stores.” While the active ingredient, apoaequorin, has been shown to improve memory function in those with very mild cognitive decline, Prevagen should not be confused with a prescription cognitive aid.

Still, our team of researchers presented us with all the information they found about Prevagen’s complete ingredient list, reported side effects, and scientific studies on the product. We’ve summarized their findings here for you today.

Prevagen can be purchased through their Official Site.

What is Prevagen?

What is Prevagen

Prevagen is a dietary supplement for brain and memory health. The supplement claims to help prevent memory loss and improve concentration. The company behind Prevagen is Quincy Bioscience located at 726 Heartland Trail, Suite 300 Madison, Wisconsin 53717. Their phone number is 877-977-3824. Quincy Bioscience has a BBB rating of A+, but it is not BBB accredited.

Prevagen contains apoaequorin, a protein from jellyfish. Supposedly it helps promote and enhance brain function. Apoaequorin apparently reduces excess calcium levels in the brain and improves short-term memory problems.

Before we jump right into the supplement, let’s take a quick look at the ingredient and research.

  • LiverTox – “Apoaequorin is a recombinant protein used as a dietary supplement that is purported to improve memory and verbal learning.”
  • Advances in Mind-Body Medicine – In aging adults, the use of apoaequorin promoted improvements in cognitive function.
  • Neuroscience Letters – With all the support for the main ingredient, we were bound to find something to negate it. Some research shows that apoaequorin may not be the right protein, with calmodulin working better.

Bottom Line

What Users Are Saying

“It works – I can recall faster than before. I recommend this product.”

“Prevagen does not work! – I was interested in improving my memory, and the advertising proclaimed a difference in two months, but I found no increase whatsoever.”

“Don’t expect a miracle, but it does help. – Was a little skeptical prior to purchasing this… had some issue with memories over 15-20 yrs ago (recall type) been on the 10 mg for almost 90 days… but about 30 days in actually felt “clearer and sharper of mind”… did help a little with recall, not as much as I’d liked but will take a few days off and then try another 90 days.”

Prevagen is considered one of the leading “brain” supplements on the market. There are even studies supporting the benefits of the active ingredient apoaequorin. However, there is also an alternative for supporting your healthy lifestyle changes.

    • Wayne Carr

      I started taking prevagen about 5 weeks ago and noticed my short term memory improving but I have also developed a rash that I thought was caused by fleas in my bedroom. No one else in my house had developed these itchy large bumps. I am quitting the prevagen which is too bad as I see it working and I have 2 more full bottles. I may try to get a refund on the last bottle I have this rash all over my body and it started around 4 weeks ago.

      • D Davey

        You might have a Doctor examine your rash. Not Provagen related, but I was diagnosed with “Grovers disease“, not a critical disease but more of an annoyance and discomfort that comes and goes often during hot weather.. Might just want to check it out, especially if the Prevagen is helping your memory.

      • dalores anderson

        you r probablt allergic to jelyfis

        • Anonymous

          Dalores Anderson, the apoaequorin in the supplement was discovered in jellyfish, but jellyfish are not where this ingredient is derived, but it is now a synthetic protein. I’m not advocating or discouraging it’s use, as I just started taking it a couple of weeks ago myself.
