Is Prevagen Worth the Money? A Comprehensive Review


As the years go by, it is not uncommon for our cognitive abilities to dwindle in size and our memory to fall short. When faced with such dilemmas, people tend to resort to various supplements to give their brains a much-needed boost. One such supplement, Prevagen, prides itself on enhancing brain function, slowing cognitive decline, and improving memory. But, the question remains- is it worth the financial investment?

What is Prevagen?

The dietary supplement Prevagen is a marketing marvel, touting its ability to enhance memory and cognitive function to the masses. At the core of this purported cognitive elixir lies apoaequorin, a protein procured from jellyfish. This brain-boosting concoction is accessible in both chewable and capsule form, readily available over the counter.

The Claims Made by Prevagen

Improves Memory

Prevagen makes grandiose claims of memory enhancement, honing in on the plight of aging individuals experiencing a decline in their ability to remember. It proudly markets itself as a risk-free and efficient mechanism to bolster and maintain healthy brain function.

Slows Cognitive Decline

To add to its repertoire of magical promises, Prevagen asserts its ability to slow down cognitive decline, an all too common issue amongst senior citizens. It asserts that its product can assist in the retention of mental clarity and focus, defying the natural aging process.

Improves Brain Function

In an effort to expand its domain of impact, Prevagen claims to elevate brain function, advocating for the betterment of mental flexibility, executive function, and attention.

The Science Behind Prevagen


Apoaequorin, extracted from jellyfish, holds the reigns as the star ingredient in Prevagen. It is believed to aid brain function by binding with excessive calcium in the brain. This connection allegedly reduces inflammation and amplifies neural transmission, promoting better brain activity.

Clinical Studies

Prevagen’s supposed scientific grounding is reinforced by clinical studies. However, some have scrutinized the studies for their lack of consistency and methodology. Despite this, one of the most notable studies was performed by the manufacturers themselves, Quincy Bioscience. The study revealed that Prevagen displayed enhancements in cognitive function and memory in older individuals. Nonetheless, the study’s credibility has been challenged, citing issues such as its minuscule sample size and lack of a control group.

Prevagen’s Controversy

Prevagen has been embroiled in a raging controversy over its efficacy and claims. In 2017, the Federal Trade Commission (FTC) launched a lawsuit against Quincy Bioscience, alleging that the company engaged in false and misleading advertising. The FTC claimed that Prevagen’s advertised ability to improve memory and cognitive function lacked substantial scientific evidence. In 2020, Quincy Bioscience reached a settlement with the FTC for $2 million, though it did not accept any liability.

Alternatives to Prevagen

For those seeking to amplify brain function, there exist numerous alternatives to Prevagen. Omega-3 fatty acids, ginkgo biloba, and bacopa monnieri are just a few supplements that have amassed considerable research supporting their efficacy, making them a safer and more reliable option.

Cost of Prevagen

Prevagen is a relatively expensive supplement, with prices ranging from $25 to $60 per month. This cost may be prohibitive for some individuals, particularly those on a fixed income.

Consumer Reviews

Consumer reviews of Prevagen are mixed. Some users report significant improvements in memory and cognitive function, while others report no effect. Many users have also reported side effects, including headaches and nausea.


The question of Prevagen’s efficacy as a memory and cognitive enhancer is a topic of intense debate. Although some studies have yielded promising results, they have been criticized for their methodology and study design. The FTC’s settlement with Quincy Bioscience over allegations of false and misleading advertising has further shrouded Prevagen’s claims in controversy.

For those seeking to boost brain function, several alternative supplements have more significant scientific backing and may be more cost-effective than Prevagen. Ultimately, the decision of whether or not to invest in Prevagen is a personal one. It is essential to review the available research thoroughly and consult with a healthcare professional before making a decision.
