Prevagen ingredients (7 Out Of 10)

There are only two active constituents in the Prevagen Ingredients list.

  • Apoaequorin

The first Prevagen Ingredient is Apoaequorin, which is a calcium-binding protein obtained from jellyfish. Some people improve memory, mental function, and sleep quality, but there is insufficient evidence to rate this protein’s effectiveness in the above conditions.

Preliminary research suggests that taking 10 mg Apoaequorin daily for 90 days may improve mental function, sleep, forgetfulness, recall, and in some people, the need for reminders.

A 2013 study in rats concluded that Apoaequorin is safe to use, and there were no side effects on the highest dose of 666.7 mg/kg BW/day.

Another Human Study suggests that Apoaequorin is safe to use and doesn’t cause hepatotoxicity and other adverse effects.

However, more authentic research is needed to test this ingredient’s test efficacy in brain function and sleep quality improvement.

  • Vitamin D (As Vitamin D3)

Another ingredient present in Prevagen is Vitamin D3. It is a fat-soluble vitamin that your body is naturally producing when your body is exposed to sunlight.

Vitamin D’s most important functions are to regulate the absorption of calcium and phosphorus and ease the immune system’s normal functioning. In addition to the average growth and development of bones and teeth, sufficient vitamin D is necessary to improve resistance to some diseases.

Why 7 Out of 10?

This supplement contains only 2 ingredients and the one is still not fully proven to be effective in the memory enhancement.

Company Claims (6 Out Of 10)

Claim#1: Clinically Tested Ingredients

  • Our Thoughts: The two ingredients present in this supplement are Apoaequorin and Vitamin D3. The manufacturer claims that it can improve memory, mental function, and sleep quality. A recent study supports the claim that It can be used to enhanced cognitive function in aging adults. Another study that was sponsored by Quincy BioScience claims the improvements in executive functioning and delayed recall.
  • However, the Federal Trade Commission (FTC) and New York Attorney General have filed a lawsuit against the manufacturers of Prevagen, claiming that there is no evidence that the pill improves memory or prevents memory loss.
  • After this, the FDA took a stand against false claims and announced a plan to regulate and oversee dietary supplements.

Claim#2: Prevagen is Safe to Use

  • Our Thoughts: Yes, if you look at the ingredients, they both are safe to use and don’t cause any toxicity. Don’t use more than the recommended dose.

Claim#3: Prevagen is the No#1 Pharmacist Recommended Brand

  • Our Thoughts: While researching the brand, our research team thoroughly checked all the facts and figures about Prevagen. According to the 2019 “Pharmacy Times” survey, 72% of pharmacists recommend Prevagen, while 13% recommend Focus Factor and other brands.

Why 6 Out of 10?

Because they claim that this supplement is clinically tested. Although some studies back these claims, there is a lawsuit against this company from the US Federal Trade Commission. They were not satisfied with the benefits of the supplement.

How Prevagen works? (6 Out Of 10)

The protein (Apoaequorin) binds to calcium, and according to some researchers, it can regulate minerals to reduce mental retardation. Calcium is believed to play a role in age-related memory function.

However, many pharmacologists and experts think that it contains a calcium-binding protein-Apoaequorin. This is an oral supplement that means that this protein will have to pass the stomach digestive enzymes. The gastrointestinal system breaks down all proteins into amino acids. Long story short, some researchers suggest that it may degrade by stomach acid and affect its potency and efficacy.

Does Prevagen work? (7 Out Of 10)

If you look at the clinical studies (although limited), product loyal customers, and Pharmacist recommendations, this product has something that works for the customers.

The product has pretty much positive reviews. Prevagen has 4/5 ratings (816 Ratings) on Amazon, telling a lot about the product. Amazon doesn’t allow an unverified reviewer to rate a product, so the above ratings are not manipulated.

But the question is…

Does Prevagen work?

If you’re experiencing age-related cognitive decline or memory loss, we think there is enough evidence to prove Pravegan. As with any diet or supplement, we recommend consulting your healthcare provider before using the product.

If you look at this supplement’s mechanism, it may degrade by digestive enzymes in the gut, and there is no other mechanism for this protein to reach into the brain.

But while researching this supplement, we have found a lot of positive customer reviews about this product.

Now that you have read our Prevagen review and want to try this product, It’s wonderful and up to you, or you can use other high-quality alternatives such as Brain Pill®

Why 7 Out Of 10?

Most of the customers were praising this supplement but there is confusion in the mechanism of this ingredient. Many experts think that Apoaequorin destroys before it reaches the brain, and when it can’t reach the brain, how can it affect your mental performance?

Where to Buy Prevagen?

This product is available on all online retailers like Amazon, Walmart, Walgreens, CVS, and many others, but the best place is the company website and Amazon.

Is Prevagen a scam?

In my opinion, this is not a scam. This brain-boosting supplement may offer some or all of the shared benefits. But due to the relatively expensive price tag and the FTC lawsuit, it is difficult for many potential buyers to try the formula.

Does Prevagen help memory?

As a pharmacist, let us use a supplement that contains already tested ingredients like Citicoline, Bacopa monnieri, phosphatidylserine, vitamin B complex, N-Acetyl L-Tyrosine, L-theanine, and many such already proven ingredients. This doesn’t mean that Prevagen will not work, but the fact is that its main ingredient is still not very well studied and need more research in this regard.

Do pharmacists recommend Prevagen?

According to a Pharmacy Times Magazine survey, most pharmacists recommend this brand, but many believe it’s a total lie.

What do we think about this product?

Aside from all the negative aspects of Prevagen, this product has received impressive positive reviews and testimonials from real consumers. This formula is supported by numerous studies and clinical trials, which is a good thing.

We could not find any specific complaints regarding company policies, which is a strong point in favor of this product. Any buyer who does not like the product or does not consider it profitable can return it without asking questions.


To wind up our Prevagen Review, There are different factors to consider before buying a supplement.

If you are looking for a memory booster, this may be the answer for you. Prevagen is a supplement that uses a proprietary ingredient called Apoaequorin.

This unique ingredient is believed to improve short-term memory significantly. It can also help improve concentration, focus, and thinking skills.

This is my personal opinion, and I’m not claiming that this product will work like a Miracle.

After reading our “Prevagen Review” and still want to buy this product, it’s totally up to you. But our #1 recommendation will always be Brain Pill®.

Our #1 Recommended Brain Supplements is Brain Pill.
