Prevagen Review 2019 – Benefits & Side Effects

What is Prevagen

More and more people show a growing interest in supplements designed to help improve and maintain healthy brain functions. This applies to all age groups. Because of this increased interest from potential buyers, the brain supplement market has become “flooded” with hundreds of different products. So what makes Prevagen different? According to Quincy Bioscience, the inclusion of their patented apoaequorin protein is what makes Prevagen stand up as one of the best brain supplements available at this moment.

Prevagen is produced by Quincy Bioscience, a US biotechnology company based in Madison, Wisconsin. According to Quincy Bioscience official website, they are “focused on the discovery development and commercialization of novel technologies to support cognitive function and other typical health challenges such as mild memory problems associated with aging.”

Their flagship supplement, Prevagen, is formulated around apoaequorin, a patented protein discovered in jellyfish. Quincy Bioscience owns the patent for this protein, which they claim to support cognitive function.

Prevagen Ingredients

Prevagen includes the following active ingredients: Apoaequorin 10 mg.

Inactive ingredients: white rice flour, salt, magnesium stearate, acetic acid, and disodium EDTA.

Prevagen contains no milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, and soybeans.

Benefits of Prevagen

Prevagen is advertised as a “brain power supplement” on its official website, that claims to offer many benefits for people who are experiencing memory loss. According to Quincy Bioscience, Prevagen can help make your brain healthier and stronger, can improve your overall cognitive function, and can boost your brain power. The formula is supposed to improve your focus and concentration during the day.

This brain supplement contains one single active ingredient: apoaequorin. This calcium-binding protein was initially discovered in a very particular type of jellyfish, but the apoaequorin used in Prevagen is obtained after a scientifically called process. Basically, the apoaequorin found in Prevagen is a synthetic ingredient.


We tried to research this ingredient online, but there isn’t much information on it. Excepting the official Prevagen website, and one page of information on Wikipedia, we weren’t able to find much about its benefits and possible side effects.

Prevagen is claimed to be a powerful brain supplement, but you’d expect a memory boost supplement to contains some ingredients that are at least somehow associated with memory support, better focus, better cognitive functions and so on. On top of that, most brain supplements out there contain at least 400 – 600 mg of active powdered ingredients, which again, is not the case with Prevagen. This product only contains 10 mg of the active ingredient.

But after considering all these, Prevagen has received numerous positive testimonials and reviews from consumers. The official website offers a decent number of testimonials, but most of these reviews can be found on major retailers such as Amazon.

How Much Does Prevagen Cost?

Prevagen is a fairly expensive brain supplement but Quincy Bioscience offers several different deals for their product:

  • Auto-ship program (Preferred Customer Plan) at $44.95 plus $5.95 standard shipping;
  • One month supply at $59.95 plus $5.95 standard shipping;

Prevagen can be purchased from a number of online retailers as well. Please note that some retailers may offer additional discounts or free shipping for orders from within the United States. Considering how expensive Prevagen is, we believe that researching into alternative purchasing options is a good idea.

Potential Prevagen Side Effects

Quincy Bioscience claims their product is perfectly safe to take and to support this statement, they publish several clinical trials conducted by the company in the past.

However, our in-depth research has revealed multiple Prevagen users have accused the company of not reporting adverse effects like seizures, strokes, and worsening symptoms of multiple sclerosis.

On top of that, the key ingredient in Prevagen, apoaequorin, is not obtained through a natural process, and it is instead a synthetic form of apoaequorin. Therefore, we recommend our readers to further research into this product before making a purchase.


  • Despite its price, Prevagen is one of the best selling supplements in the United States
  • Unique, patented formulation
  • There is a lot of research backing this brain supplement

Final Verdict

Leaving all negative aspects of Prevagen aside, this product has received an impressive number of positive reviews and testimonials from real users. The formula is supported by a number of clinical studies and trials, which is a good thing.

Quincy Bioscience official website looks professional, well organized and able to provide the customer with enough useful information regarding their flagship brain supplement.

We were unable to find any specific complaints regarding the company’s policies, which is, again, a strong point in their favor. Buyers who do not like the product, or do not find it beneficial, can return it for a full refund, no question asked.

So, “is Prevagen a scam?” We believe the answer is a strong “no.” This brain supplement may offer all or some of the advertised benefits. But being a relatively expensive supplement makes it difficult for many potential buyers to be able to try the formula.
