Prevagen is a brain supplement that was designed to support better brain health and better brain functioning. This brain supplement is produced by Quincy Bioscience. According to its manufacturer, Prevagen was created as a supplement that promotes and enhances brain functions by improving memory and protecting the brain by supplying it with the required protein, apoaequorin. This protein has the property to bind calcium ions, given the essential role of this mineral in a number of bodily processes and functions.

It is a known fact that the brain protects its cells from degradation by generating a special protein that controls cellular calcium. If calcium exceeds a certain limit in cells, they will be destroyed. With the natural aging process, the body generates this protein in smaller amounts which can eventually lead to increased levels of calcium in cells. This is the science behind Prevagen.

Prevagen Ingredients

Prevagen contains the following ingredients: Apoaequorin (10 mg), white rice flour, sodium chloride, magnesium stearate, ccetic acid, TRIS buffer, and EDTA.

Product Features

According to its developers, this is a supplement that possess the property to bind calcium in cells, thus reducing the damage which occurs when the body stops to produce enough calcium binding proteins. The key ingredient in this formula is the apoaequorin protein which is extracted from jellyfish.

The protein responsible for the whole calcium binding process, the apoaequorin protein, was discovered in the early ’60s. Several researches conducted by this supplement’s manufacturer allegedly demonstrated that the apoaequorin protein mainly benefits consumers by enhancing their decision-making skills, mental clarity and it helps them improve the short term and the long term memory. The manufacturer cites several studies that testify to the key ingredient activity in relation to memory and sleep quality. However, these are small scale studies and relevance may therefore be an issue.

The Prevagen memory benefits seem to be supported by consumer testimonials available in a large number. Nonetheless, there are certain voices that claim that, like as many other brain enhancing formulas producers, this too favor marketing over thorough research and development. A significantly large number of Prevagen reviews from consumers also report minimum effectiveness, and important side effects not mentioned by the manufacturer.

While these research studies haven’t been confirmed by the FDA, the producers’ website promises consumers positive results between periods of use from 30 to 90 days.

  • This is a very expensive product;
  • Prevagen reviews report mixed results;


The aging process does affect the body in multiple ways and the brain is no exception. If this formula is really as good as advertised by the manufacturer, people will really benefit from this supplement. However, given the supplement’s shortcomings, caution should be taken prior to its consumption. Prevagen’s side effects, although not specifically mentioned by the producer, may prove rather serious. These may include chest pain, seizures, tremors, and fainting.

On the other hand, Prevagen is one of the best selling brain supplements in the United States and that can’t be ignored. Part of its success might be because of the aggressive marketing campaign behind this brain supplement, that is true, but even so Prevagen may be a good solution for those looking for a decent brain supplement.

    I have read comments on here that this is being given to children and it should NOT be. Please don’t give your children this. Speak to a Doctor before you even think about it. Young brains are still developing.
    Prevagen commercials should state this Immediately.

  2. 2

    I`m one of the worlds biggest skeptics with everything.
    However, Prevagen works for me without a doubt.
    As a long time musician and lead vocalist, Prevagen really is a huge reason my memory now is better than before. I`ve been taking Prevagen now for at least 5 months. my focus is “On task”.

  3. 3

    The only difference between Prevagen and other self-described brain supplement products is the Huge Amount of Advertising for Prevagen on the Nightly News.

    It has the look and feel of

    Page loaded with 3 stars, can’t change up or down.

  4. 5

    I have been taking Prevagen for about two months. I’m definitely feeling moe focused and energetic, it seems to have lifted me out of a very lethargic period in my life. This may definitely be psychosomatic – if so, too bad my placebo isn’t a bit less expensive! I’m noticing more aches and pains, but this could definitely be due to the fact that I’ve increased my activity level by about 200%. I will continue to take Prevagen and see if my focus and energy continue to stay high; I’m really enjoying life these days.

    Notes: My 2009-15 illness has been eliminated for many Medicar and Medical help. Prevagen has been used 2009-12, and more doctors haven perscripted mord since. All good! :)

  6. 7

    Know someone who has been taking prevagen for 6 months now. They have changed they way they are. They have become overly focuses, won’t stop talking about the same subject until others can’t listen anymore. They are too focused and overly detailed, not a good mix. Definitely a side -effect.

    Gerald Carroll

    Already have enough nutriants by doctor’s prescriptions. Do NOT need to purchase any of these. Thank you.

  8. 9

    I’m still quite undecided about Prevagen’s effectiveness. My metabolism has gone through 30 days’ worth of pills without any side effects and while my supervisors say that my efficiency has gone up, I need another month or so to be fully convinced. So far, so good!

  9. 10

    After being in a car accident a few years ago is wear I started having major memory problems and my concentration was terrible!! But after using Prevagen for two months I feel like I’m back to my old self. I’m more focused and alert and I can remember everything I need to do every day without making lots of lists.

    I’ve used this product for 1 month and I can’t see any visible results yet. However, as they say it might take up to 90 days to see its effects, I’ll use it for the whole period.

  11. 12

    I would like to hear comments comparing this product to EHT, which has 30 years of research at Princeton & seems to have cerebral benefits beyond delay or prevention of Alzheimers.

      Hi Rosie,

      According to the manufacturer, this supplement is mostly recommended after the age of 40, because that’s when our brain begins to need more cognitive support and when Prevagen’s results are most visible.

    I’ve bought them for my 70 year old mother and after 2 months she says she doesn’t have nearly so many memory lapses.

  13. 17

    I was at work and had stroke like symptoms. My co-workers called 911 and I was rushed to the hospital. They ran all sorts of tests to see what was wrong and all of the tests came back negative thank God. The only change I had in my routine was that I started taking Prevagen a few weeks earlier. My wife started researching the product and found out that the product has some bad side effects. I stopped taking the product immediately. The FDA stats that Prevagen should be sold as a drug because they are synthetically creating the protein that is found in some jelly fish.

  14. 18

    I thought it could not hurt to try. I am using the extra strength. I am on my second month. I notice my productivity has improved at work because I am able to stay better focused. I feel like I can think more clearly and my memory seems improved. Like I said, this is only my second month but I think I am getting some results. It is expensive, but so far it seems worth staying on for a while.

  15. 19

    I am 48yrs old and have noticed pretty severe memory loss over the last couple of years. I have taken prevagen for two weeks and notice a very positive difference! My only concern is that it is not FDA approved! My other concern is that people here seem to be giving it to CHILDREN! Do Not Give This To Children! If your kids are that distracted perhaps do some research on the effects of too much screen time on kids ie joe much time they spend in front of a computer, tv, game station or smart phone.

  16. 21

    WARNING: Be POSITIVE you read the FDA information regarding this stuff like strokes and other side effects. They keep referencing “clinical studies”. What clinical studies? What RECOGNIZED study has been done? Why is this marketed by way of a FAKE news program? Why has the FDA warned these people? The answers to all those questions should tell you what you’re dealing with here. Oh yes…don’t forget the word “STROKE”!

  17. 23

    Prevagen actually helped me with some of my memory issues! Sure, I still have issues finding my keys now and then, but I don’t have any of those silly memory slips anymore.

  18. 24

    I love taking memory tests and got quite obsesed with them so I started taking supplements to see the improvements. This formula helped me quite clearly with my memory.

  19. 25

    The good thing about Prevegan is that it is available over the counter in Walgreens. My husband took it for about 4 months and I could see an improvement. It is expensive in my opion. Around $60. for a bottle, if not on sale.

    Merletta Matthew

    The first time i used the product it seemed that i drank a coffee or something, but after a longer period of time it really started making a difference, it is much easier to stay focused.

  21. 27

    I don’t think that this supplement is actually working. I have tried it for 2 months and I didn’t notice anything different and nothing like better health for the brain and an enhancement of its functions. Such a waste of money…

  22. 28

    My initial goal with this product was an increase in my school grades before the end of the semester. However in only 4 weeks I managed to improve them all. Then I decided to improve them all. Then I decided to use it permanently and try to undertake more challenging tasks. It works perfectly!

  23. 29

    How I found out about Prevagen is a long story and I won’t tell it here. But, although it has many satisfied users, I can say that it didn’t help me at all.

  24. 30

    I am so tired of trying so many supplements and pills that have no effect, this one included. Although I have read many positive testimonials and reviews about it, for me it doesn’t seem to work.

  25. 31

    I went to my doctor because I needed something in order to concentrate better and to improve my memory. Although I have taken almost 2 months Prevagen, I am not noticing anything different.

  26. 32

    My kids are so easily distracted by noises and events happening around them and they are not able to concentrate any more. Since we have started the treatment with Prevagen, they pay attention more often.

  27. 33

    Prevagen does wonders for my kids. Since they have started the treatment, their ability to concentrate increased significantly and also their short term memory improved. We are happy, as parents, to see that our children are getting better. Thanks!

  28. 34

    I am a programmer and I have to stay late at night to finish all my projects in time. Prevagen helped me to meet all deadlines by now and gave me energy and confidence to take new projects.

  29. 35

    I saw a old friend in a store recently. She told me she was doing so much better now since she had been taking Prevegan, clearer mind, etc. I told her that was great and that I didn’t know that she was having trouble before. She was convinced and sold on the product. I want to give it a 3 month try soon as soon as I can come up with the extra cash.

  30. 36

    I have noticed positive results regarding my ability to focus and concentrate. Also my memory is improved since I have started Prevagen treatment. It is a good way to prevent aging and his damaging effects.

  31. 37

    I used to take a lot of energy drinks and drink way too much coffee. It was a very chaotic time but it was necessary for me to overcome constant stress. Now I don’t need that anymore because I take Prevagen.

  32. 38

    This is a memory enhancement supplement that really works. I use it to fortify my memory and after 4 months of treatment I have noticed positive results. My husband just started the treatment and I hope he will feel the difference, too.

  33. 39

    I am using this supplement for a while and I can say that my memory improved and my headache migraines significantly decreased. I can concentrate better at my work and I hope I will get my promotion next week.

  34. 40

    As a general purpose brain supplement, Prevagen is among the best you can use. It will make you feel you can deal with many issues without fear of failure. Tasks that previously seemed daunting now will prove to be effortless. This is my honest recommendation.

  35. 41

    Prevagen has been the first supplement I’ve ever taken. It’s been an interesting experience because I’ve monitored my progress carefully to see if I was able to do anything that I could not do before. With the exception of the fact that I don’t feel exhausted in the evening not much has changed. Overall it’s been nice, I don’t regret trying it.

  36. 42

    I used to drink a lot of coke and energy drinks but after a while I started to get dizzy and I would get tired all the time for no good reason. My mom gave me Prevagen because she said it will help me recover and she was right. It took me only two moths to be my old self.

  37. 43

    This is one of the many drugs that do the same things. Seriously, this is like the tenth different product and i can’t tell any difference. Slight increase in overall energy, easier to keep focus and seems to reduce mood swings.

  38. 44

    I’ve tried to evaluate the effects of this product objectively but I failed completely at it. I have very erratic mood swings and I have long periods of time that I feel ok. Using Prevagen did not break this pattern, but I do feel a little better overall.

  39. 45

    I’ve used this product successfully to get over my recent apathy onset. I’ve had less and less energy over the last three months and I started getting scared. Thankfully my mom gave me Prevagen and now I am pleased to say I’m back to my old self.

  40. 46

    I have more energy that I used to have on a daily basis. It’s made a real difference in my life and I don’t regret trying it.

  41. 48

    My father tried this and barely felt any improvements. This may not be the sure thing many are claiming to be.

  42. 49

    Effective but expensive at standard price. You must look for a good deal since the price varies from expensive to cheap depending on where you look for it. I bought it from Amazon at a good price but you may find it cheaper if you try.

  43. 50

    I have been ordering Prevagen for both my parents for three years. they are in their 70s and I can see that they are feeling more energetic when they take these pills. It’s true Prevagen is a bit expensive but I usually manage to buy it at a discount.

  44. 51

    I purchased Prevagen hoping that it would help me go through a difficult period at work. It didn’t however I decided to keep taking it at least three months, as the producer says. Now I think it really works.

  45. 53

    My father was diagnosed with alzheimers last year. 2 months ago i heard from a radio program about prevagen and how this product can help those who suffer with this terrible disease.

    My fatherr has been on this medication long enough for it to be in his system. I have not seen any change.

    I was not looking for a miraculous drug because i am well aware that such thing doesnt exist…but im truly disappointed and frustrated with this drug.

  46. 54

    Ok, they say this supplement is for memory. So I originally purchased prevagen for memory issues. After about 40 days with overage results i noticed that the frequency of my migraine headaches and intensity has dropped by about 50%. Now i’m using prevagen to treat my headaches, rather than improve memory :)

  47. 55

    I got prevagen for my grandfather (79 years old). He is now finishing crosswords and puzzle games! Thank you!

  48. 56

    hmm, i wonder how many of their testimonials (the ones posted on prevagen’s website) are real. all i can see are positive reviews while the product appears to be utterly ineffective.

  49. 61

    Very good product. I find that Prevagen increases my ability to remember things and feel a sense of emotional balance.
