Overview of Prevagen

Prevagen was launched in 2007 by a company called Quincy Bioscience, which was founded by Mark Underwood. Using his background in neurochemistry, Underwood set out to develop a brain-boosting supplement.

The inspiration? His own family has suffered from brain diseases.

In an interview with the Milwaukee Business Journal, Underwood discussed the need for a product like Prevagen: “There is a huge need in the marketplace for improving the health of those over 40 years old. The dramatic changes in the economy and our health care system are placing more responsibility on baby boomers to stay healthy.”

Prevagen claims to be able to help you get a sharper mind, clearer thinking, and a healthier brain, resulting in overall better memory. But, does the product live up to the hype?

To find out, keep reading this Prevagen review. First, I’ll take you through some initial highlights:


  • Clinically proven to help with mild memory impairment caused by aging
  • Supports brain function
  • #1 pharmacist recommended brand
  • Available in capsules, chewables, and protein powder form
  • Sold at major retailers across the US, including CVS, and Walgreens
  • Flat rate shipping fee

Prevagen Review

Getting older is something that we all think about, but we tend to focus on the superficial things that are visible, like wrinkles and gray hair. What we don’t think about as much, and what is arguably more important, are the changes that occur beneath the surface, such as changes to your brain’s abilities.

Forgetfulness is a normal side effect of aging, and normal age-related cognitive decline[1] can begin as early as your 20s. Additionally, memory loss doesn’t just have to be associated with aging. Studies[2] have shown that major depression is associated with memory impairment, as is stress[3].

All of us have experienced forgetfulness in some shape or form. Whether it be losing your keys, forgetting if you turned the stove off, or missing that appointment you made. But, there are times when it can get to be too much. Maybe you have lost your keys one too many times.

Whatever it is, a memory-boosting supplement like Prevagen might be able to help.

Prevagen claims to be able to not only improve your memory, but give you a sharper mind, clearer thoughts, and an overall healthier brain. To find out how Prevagen does this, I took a look at their active ingredients and did a little research of our own, which you will find below.

To reap the benefits of Prevagen, you only need to take one capsule a day. Ready to level up your brain health? Pick up a bottle today for $40 on the official Prevagen website, or at major retailers such as CVS and Walgreens. Each bottle contains a one-month supply of 30 capsules.

Who Is Prevagen For?

Prevagen Review - Must Read This Before Buying (4)

Prevagen is marketed towards older adults since they’re the group that most often struggles with memory and keeping their minds sharp. However, it’s not meant for anyone that already has moderate memory loss or brain disease. It’s simply meant to help keep healthy brains healthy.

Although Prevagen is marketed towards an older demographic, it can be used by anyone. Since normal, age-related cognitive decline can begin as early as your 20s, you might still benefit from Prevagen even if you’re young. Worst-case scenario? Your brain gets a little extra support to stay in tip-top shape.

How Does Prevagen Work?

Prevagen Review - Must Read This Before Buying (6)

Prevagen works by giving your brain the supplies it needs to run at its best. Vitamin D deficiency is associated with memory impairment, so by making sure you have enough, this supplement can support your memory.

Similarly, Apoaequorin, a calcium-binding protein, works to support the pathways that are essential for the formation and maintenance of your memories.

Next, let’s take a deeper look at these Prevagen ingredients.

What Are the Ingredients In the Prevagen?

Prevagen Review - Must Read This Before Buying (7)

Prevagen’s benefits come from their two key ingredients:

  1. Vitamin D: although it’s known as the sunshine vitamin, vitamin D has a role in memory too. One study[4] showed that there is a relationship between severe vitamin D deficiency and visual memory decline. This is pretty wild considering nearly 42% of Americans have a vitamin D deficiency! Another study[5] showed that low vitamin D levels are associated with lower cognitive function and an increased risk of Alzheimer’s disease. While Prevagen doesn’t promise to ward off brain diseases, its inclusion of vitamin D, and the evidence that we found for its benefits, seem pretty promising.
  2. Apoaequorin: this is where things get interesting. Apoaequorin[6] is a protein derived from our friends in the sea: jellyfish. Memory formation and recall[7] are dependent on calcium channels, and apoaequorin is a calcium-binding protein. One study[8], conducted on adults with self-reported memory issues, found that apoaequorin can improve verbal learning.

The rest of the ingredients in Prevagen act as stabilizers for the capsules themselves: microcrystalline cellulose, vegetable capsule, and maltodextrin. There is also 2% or less of casein peptones, lactose, magnesium stearate, corn starch, salt, and sugar.

How to Take Prevagen and Dosage

You can also buy Prevagen as a protein powder, taking it just like you would a regular protein powder. Just mix one pouch into a glass of cold water, shake it up or blend it. You can even use it in a fruit smoothie if you want!

Prevagen Reviews: What Do Customers Think?

Prevagen Review - Must Read This Before Buying (10)

Choosing a new supplement can be tricky. You want to go in with an open mind, but you also want to be sure that you’re not throwing your money away on snake oil. I get it!

So, to help you out, I scavenged the internet to collect reviews from real customers, both the good and the bad. Let’s get into it.

To start, I took a look at reviews on Prevagen’s official website. I noticed that most reviews came from customers over the age of 50.

One customer, a retired 67 year old named Mark, said: “The difference between then and now is considerable,” referring to the time before he started Prevagen. He went on: “Since I started taking Prevagen, I think my cognitive functions have changed – for the better!”

I also took a look at reviews from third-party sellers:

  • CVS: 4.3/5 stars from 157 reviews
  • Walgreens: 4.2/5 stars over 977 reviews

One customer said: “It has been a wonderful product for me. Recommended it to my parents who just told me he has noticed some improvement and he is 85 years old. The only concern we have is the price, especially if you are on a fixed income.”

One 90-year old customer shared: “I have been using Prevagen for the past 3 years. My short-term memory has improved 100% during that time. I don’t need anyone around me to remind me of events that have recently taken place. I have friends who cannot remember what they had for breakfast. I am trying to get them to start taking Prevagen.”

However, others weren’t so convinced. Multiple customers stated that they did not notice a difference in their memory after starting to take Prevagen.

For the most part, customers seem to enjoy Prevagen and have been singing its praises. At the same time, there are some skeptics out there, but this is common with most popular products.

While it seems that the majority of customers who have reviewed the product are seniors, there were a few reviews from people in their 40s too. It seems like it’s a product that can work well for a range of ages.
