Let’s take a closer look at the dietary supplement. Its benefits, ingredients, manufacturers, pros, and cons.

The benefits of taking Prevagen

Some brain supplements claim specific benefits such as increase memory, better focus, and improved thinking. But, in the case of Prevagen. The claims are general and slightly vague.

The potential benefits of this supplement as listed in the bottle include:

  • Clearer thinking
  • Sharper mind, and
  • Healthy brain function

Does Prevagen have the ingredients to bring about these changes? How does this supplement work? Let’s tackle these questions one by one.


On the label of the bottle. Listed are all the ingredients that makeup the capsule/tablet and the supplement mix. We are more concerned about substances that have a direct impact on the cognitive function of the users. Hence, we shall restrict our discussion only to the three ingredients that makeup the core of the supplement.

Prevagen contains milk, which makes it a vegetarian product, and not vegan. The manufacturers recommend taking one capsule a day, in the morning, with or before food.

Apoaequorin (10mg)

The beautiful and graceful glowing jellyfish has always fascinated the observers.

But, ever wondered what makes them glow and what has the glowing jellyfish got to do with Prevagen?

The main ingredient in Prevagen. – Apoaequorin – is a protein extracted from glowing jellyfish.

This protein binds with calcium ion to create the beautiful lighting effect. As seen in the glowing jellyfish called Aequorea Victoria.

Research on apoaequorin started a few decades ago.

Scientists researching the protein found that the jellyfish-extract also worked as a cognitive enhancer, improving cognitive faculties that decline as we age.

In older adults, scientists hope to use apoaequorin as a treatment drug to arrest the cognitive decline and improve symptoms of mild cognitive impairment.

Normal people aren’t prohibited from taking this protein.

In fact, the Prevagen supplement has students, professionals, entrepreneurs, and anyone wanting to improve cognitive function, irrespective of age, as its target customer.

The protein is absolutely safe to use.

After a thorough study, scientists have found that apoaequorin is a lot similar to the endogenous calcium-binding protein in humans.

The makers of Prevagen claim that apoaequorin can treat mild memory and cognitive problems, and improve memory, focus, and thinking in normal individuals.

They are constantly working to find new applications and discover hidden benefits of apoaequorin.

Vitamin D (D3 cholecalciferol) (50 mcg)

Vitamin D plays a huge role in regulating the emotional health of the users.

Individuals with less than adequate levels of this vitamin often experience anxiety, stress, and depression.

Vitamin D taken as a supplement will regulate the neurotransmitter serotonin to improve mood.

Vitamin D supplements are suggested during winter. Especially to people residing in countries with a colder climate.

During winters when the days are short our body doesn’t produce enough vitamin D; this, in turn, affects our mood and emotional wellbeing.

Taking Vitamin D supplements can help beat users the winter blues.

As an important ingredient in Prevagen, Vitamin D influences the neurotransmitters in the brain that regulate our mood.

Apart from its function as a mood enhancer, the vitamin also boosts focus and concentration of the user.

Acetic Acid

Acetic Acid, also known as Ethanoic Acid. Used quite a lot in the food we eat. The ingredient is also present in vinegar.

As an ingredient in Prevagen, the acetic acid helps the user concentrate and focus.

Studies also show the substance to be effective in treating dementia and Alzheimer’s disease.

According to a study in Japan, acetic acid was given to rats in the form of vinegar, the results showed a clear improvement in cognitive function.

In a similar study, scientists found that acetic acid improved the production of HspA1A – a protein much like HSP70 that prevents the formation of amyloid in the brain.

Who manufacturers the supplement?

The supplement Prevagen is produced by a Wisconsin based company called Quincy Bioscience.

The company is involved in the research and development of products.

That boost cognitive function, treat health problems caused by aging, and improve the overall health of the users.

Quincy Bioscience is best known for its work on apoaequorin.

The company has patented apoaequorin, which is a substance taken from jellyfish.

The company has earned praise for finding new and innovative practical applications of the substance.

Quincy Bioscience produces apoaequorin in a start-of-the-art facility that’s cGMP compliant.

Quincy Bioscience produces apoaequorin-based products such as Prevagen and NeuroShake.

The company’s Quality Assurance Department abides by the cGMP guidelines as stated in Part 111 of Code of Federal Regulation Title 21.

Quincy Bioscience ensures its products are tested for safety, strength, and purity.

Prevagen is one of the leading supplements with apoaequorin as its ingredient.

In a trial, the Prevagen supplement has demonstrated. Its potential to enhance cognitive functioning in users with normal to mild age-related cognitive decline.

According to Nielsen, a market research company.

The data collected from chain pharmacies across America clearly shows Prevagen to be the best sold cognitive enhancer of 2016.

How does Prevagen work?

In simple lingo, Prevagen works by maintaining adequate levels of calcium in the body.

Experts call this calcium homeostasis. Calcium in our body is not only crucial for bone health; it plays a vital role in the normal functioning of the central nervous system.

In studies carried out by various organizations, researchers have found a clear link between lack of adequate levels of calcium and steady age-related cognitive decline.

The makers of Prevagen claim that introduction of Ca2+ (free calcium) has proved to improve certain aspects of cognitive functioning in users with normal aged brain or mild age-related cognitive decline.

The makers also claim that taking a 10mg capsule of the supplement for 3 months continuously.

This will improve brain function of users. Furthermore, taking a 20mg capsule, a couple of hours after waking up.

Consuming a 30mg or 60mg capsule of Prevagen, half an hour before going to bed.

In addition to other prescribed medication, will slow down the progress of ALS.

In lab studies, apoaequorin – the protein previously extracted from jellyfish.

But now synthetically made has shown to control calcium levels in neurons.

Researchers also found the jellyfish protein quite effective in protecting neurons against ischemic cell death.

Examining the working mechanism of apoaequorin. Berkeley Wellness has used the term ‘scientifically implausible’.

To describe the hypothesis and claims made by Prevagen’s researchers.

Even otherwise. Experts believe that like any other dietary protein.

The main ingredient is easily broken down inside the stomach.

Hence, there is no or only a very slim chance of apoaequorin reaching the bloodstream.
