Prevagen ingredients (7 Out Of 10)

There are only 2 active constituents in the Prevagen Ingredients list.


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

While another Human Study, suggest that Apoaequorin is safe to use and don’t cause hepatotoxicity and other adverse effects.

However, more authentic research is needed for the test efficacy of this ingredient 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 is naturally producing by your body when your body is exposed to sunlight.

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

Why 7 Out of 10?

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’s claim that it can improve memory, mental function, and sleep quality. A recent study supports the claim that It can be used to improved 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 takes a stand of false claims and announced a plan to regulate and oversight the 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 there are some studies that 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 that it can regulate minerals to reduce mental retardation. Calcium is believed to play a role in the age-related memory function.

The problem with this supplement is 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 may 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 obviously has something that works for the customers.

The product has pretty much positive reviews. Prevagen has got 4/5 ratings (816 Ratings) on Amazon which is obviously telling a lot about the product. Amazon doesn’t allow an unverified reviewer to give ratings, 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 beginning to use the product.

If you look at the mechanism of this supplement 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.

It’s totally up to you if you want to give a try to this product it’s well and good or use other alternatives.

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 Probably 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.

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.
