What are the side effects of Prevagen?
One of the most important things I tried to cover in my detailed product review was the potential Prevagen side effects. However, I still regularly receive questions from concerned users about the potential health and safety risks of using Prevagen, so I thought it was worth answering th equestion on a dedicated page.
Prevagen is still an extrmeely popular and widely used nootropic supplement. Quincy Bioscience are constyantly advertising online and on TV, and their underhanded tactics lead many people to believe that this is a pharmaceutical-grade, pharmacist recommended memory supplement.
Well, it isn’t!
Prevagen is, in my personal opinion, an outright scam. It contains just one ingredient which has never been proven to work in independent clnical trials. The only evidence backing this ingredient up was published by Quincy Bioscience on their website in the style of an adcademic study.
Despite these facts – and a very public lawsuit brought against Prevagen by the FTC – people still buy Prevagen in their thousands. So, it’s important for us top consider the safety and side effect risks associated with this nootropic.

Let’s take a look at what is in Prevagen and find out whether or not this brain supplement is safe for everyone.
What is in Prevagen?
Prevagen is billed as a safe, natural brain supplement which delivers enhanced memory function and supports brain health.
Besides Vitamin D, Prevagen contains just one active ingredient: apoaequorin.
I have explained multiple times elsewhere on this site that apoaequorin is a protein obtained from jellyfish. As a photoprotein, apoaequorin is responsible for producing the bioluminescence associated with some jellyfish species.
Like a lot of scammy nootropics, Prevagen relies on the exotic and unusual nature of apoaequorin to trick people into thinking thta it is a potent memory enhancer; it’s a special protein only obtainable from jellyfish, so it must be a miracle drug, right?
There is absolutely no evidence that apoaequorin has any discernible effect on memory function. This is true of older people with cognitive decline and healthy young people; in either case, apoaequorin does nothing.
The “clinical trials” Quincy Bioscience are often harping on about are just in-house studies written up as PDFs and published on the company’s own website.
Such hard hitting science!
Even the results themselves put out by Quincy Bioscience are uninspiring; in one subgroup Prevagen gave participants a 3% edge over the placebo group in memory tests.
So clearly Prevagen doesn’t actually work for memory.
Its only ingredient is a complete dud.
But is it safe?
Will Prevagen cause side effects?
Considering that apoaequorin has not been properly tested by indpendent, large-scale, long-term clinical trials, I have to say that it should not be considered a safe nootropic.
In the “studies” published by Quincy Bioscience, none of the participants reported serious or notable adverse effects. As far as I can tell not a single participant reported any side effects of any kind.
However, you need to keep in mind the fact that this is just a PDF describing a trial, published only on the manufacturer’s website. This trial was not carried out under third-party supervision, and it has not been repeated by independent medical researchers.
To make matters worse, we know that Quincy Bioscience are not afraid to falsify study results. In the lawsuit brough against the company by the FTC, the regulatory body said that Quincy Bioscience was deceiving the American people by making claims not substantiated by their research. The FTC said that Quincy Bioscience’s own studies did not show that Prevagen improved memory function, let alone that it is an effective treatment for cognitive decline or memory loss.
So obviously we cannot trust the side effect reports 100%.
The simple fact is, if a substance has not been put through independent clinical trials, then it cannot be considered safe.
We have no way of knowing what side effects Prevagen is likely to produce. We certainly have no idea what the long-term side effects of Prevagen might be.
Until some good, long-term clinical trials come out, I’m advising everybody to stay away! Read my detailed Prevagen review to learn more about the pros and cons of the nootropic.
In summary: Does prevagen cause side effects?
A 10 mg dose of Prevagen has supposedly been used safely for up to 90 days. But it’s really unclear what side effects Prevagen might cause as this was not an independent study. Possible shot-term side effects include headaches, dizziness, and nausea.
