Prevagen Review - Does This Memory Supplement Really Work?

By Summer Banks on Nov 07, 2016
Prevagen Review

You may be surprised by what I say in this Prevagen review. We at DietSpotlight dug deep and thoroughly researched the ingredients, side effects, customer-service quality and scientific studies. Plus, we took a close look at hundreds of customer comments and reviews. Then, we compressed all the facts to give you the info you need.

EDITOR'S TIP:

What is Prevagen?

First off, Prevagen is an over-the-counter dietary supplement containing the active ingredient Apoaequorin. [1] Take one each morning and it supposedly improves memory, promotes clearer thinking and a sharper mind. [2] The product doesn’t contain synthetics – impressive.

Prevagen was first introduced in 2007 by Quincy Bioscience.[3] Although it’s not sold on the official website, several trusted retailers have it on the shelves. We like the longevity of the company and that we located some favorable customer comments, but read on…

Adverse Effects – “A Consideration?”

The first thing that concerned us were reports of Prevagen side effects. [4] “We read one review after another with claims of negative reactions,” says our Research Editor. “That’s not what the customer is looking for.”

One user complained, “Developed heart flutter about 75 days after I started taking this.”

“Upon taking my first Prevagen, within a half hour I became light headed and dizzy and my focus was worse than ever the rest of the day,” commented one user.

Another person said, “I don’t have high blood pressure and it made my blood pressure go up.”

User Complaints – “Another Concern”

Numerous customer complaints are posted online concerning Prevagen. One user stated, “I had a reversal of memory while taking this product. Many instances where I forgot peoples’ names in public situations.”

Another customer said, “I took the Prevagen 10mg pills for 30 days and I honestly don’t notice any difference. Don’t waste your money on this.”

There are some users who saw positive results.

“The change was subtle to begin with but has suddenly became more noticeable by the 4th month,” said one person.

Some felt the results were good, but the price was a little over the top.

I have taken this product with positive results but I think it is too expensive,” offered up one user.

The extensive research we’ve done has revealed if there is a particular facet of a dietary supplement that’s concerning, such as too many user complaint, the probability of long-term success is low. If Prevagen does cause reactions in users, this could be a serious problem.

The Science – “Is it Legit?”

There are some studies presented on the official website that pertain to Apoaequorin, the active ingredient in Prevagen. While this is good to see, there’s no proof this product relates to weight-loss. Also, the FDA had to issue a warning about this product because it can lead to side effects. [5] At DietSpotlight, research is imperative. If the science doesn’t back the claims or support you losing weight, we raise the red flag.

The Bottom Line – Does Prevagen Work?

So, should you race out to buy Prevagen? Well, we like that Prevagen is easy to find and that we found, but the research not pointing toward weight-loss leaves us concerned. [6] Furthermore, we have some issues with the numerous customer complaints, especially relating to adverse effects. [7] [8] [9]

Do you want to lose weight and improve wellness? Consider combining Prevagen with a supplement containing clinically-tested ingredients shown to help with weight-loss.

Among the best products we’ve seen in 2016 is one called Leptigen. This supplement contains clinically-tested ingredients, which have been shown to help boost metabolism and accelerate fat loss. We have not found any talk of harmful side effects and user comments indicate people are seeing substantial results.

The makers of Leptigen are so confident in their product they’re offering a Special Trial Offer, which is a good sign.

How Does Prevagen Compare?

Previous Prevagen Review (Updated June 16, 2014):

What You Should Know

The brain protects its cells from degradation by generating a protein that regulates cellular calcium. If calcium increases in cells, they will be destroyed. With the natural aging process, the body generates that protein in lesser amounts. Prevagen is a supplement that promotes the better health of the brain and its functions, in much the same way Focus Factor does. The product focuses on improving memory loss and protecting the brain by supplying it with a protein called apoaequorin. This protein belongs to a family of molecules that binds calcium. Prevagen can easily be bought from health food stores as well Rite Aid stores. However, the website’s online shopping page allows interested clientele to purchase the amount they want.

List of Ingredients

The only ingredient that is mentioned on the website is the apoaequorin protein, which is extracted from jellyfish. Even the concentration of that protein isn’t mentioned in the Prevagen material.

Product Features

Prevagen claims to bind calcium in cells, thus reducing the damage which occurs when the body doesn’t produce many calcium binding proteins as it ages. Prevagen, like Vibra Slim, is designed for people 40 and older. The apoaequorin protein, which was discovered in the early sixties, is apparently responsible for the whole calcium binding process. Prevagen, along with Ambislim PM, also promotes restful sleep. This effect is a double-sided coin, as we discuss on our Prevagen Side Effects review The research conducted by the supplement’s developers supposedly demonstrated that the apoaequorin protein mainly benefits consumers by enhancing their mental clarity, honing their decision-making skills, improving their memory and helping them focus. This affect on the brain is similar to how the leptin in Leptinal impedes the hunger signals in your brain. However, these claims haven’t been confirmed by the FDA. Still, the website promises consumers positive results between periods of use from 30 and 90 days. Aside from that, the product has been approved to be kosher by two of the four main production facilities in the United States.

See Our Featured

Advantages

  • The website does offer supporting evidence regarding Prevagen’s effects on memory and sleep.
  • An informative video explains how the supplements will enhance the brain’s functionalities.
  • The website directly states that it hasn’t been FDA approved, thus spares consumers the time and effort of trying to locate the FDA approval stamp.

Disadvantages

  • The product isn’t FDA approved. Although the website was truthful enough to mention this fact, it still isn’t a favorable factor.
  • There are no indications regarding Prevagen being free from side effects.
  • The supporting studies were limited studies, not full-scale ones.
  • The evidence supporting the product is mainly anecdotal and not quantitative.

Conclusion

Age does affect the body in various ways, and the brain is no exception. Age has a very taxing affect on the body and mind; numerous products including Nature's Pearl try to tackle this. If Prevagen is really as good as it claims to be, people will really benefit immensely. However, with the supplement’s shortcomings, caution should be taken prior to its consumption.

Prevagen Side Effects:

While natural weight-loss supplements may seem like the safer option, they still come with risk. With every formula, there is the potential for a negative reaction. Though Prevagen side effects are rather uncommon, that doesn’t mean they don’t exist for some users.

Fainting

Syncope or fainting is a sudden loss of consciousness for a brief amount of time. It may come from a sick feeling and often nausea is associated with fainting. Some injuries may be caused by fainting, since the person usually falls to the ground suddenly.

What causes fainting?

Fainting may be caused by a number of different conditions. It may be caused by heart issues, low blood sugar, anemia, seizures, irregular heartbeats, nervous system issues, genetic issues and certain medications. [1] Usually, fainting only lasts a few minutes.

Chest Pains

Any pain felt in the chest may be described as a chest pain. Not all chest pains are heart related. A momentary chest discomfort may be felt or the discomfort may only be associated with breathing. Some types of chest pain actually get better with exercise, as well.

What causes chest pains?

While a heart attack is the most common cause of chest pains, it’s not the only cause. Chest pain may also be caused by angina, aortic dissection, pericarditis, heartburn, gallbladder issues, sore muscles, injured ribs, a panic attack, shingles, pulmonary embolism, collapsed lung or pleurisy. [2] Even some medications and supplements may cause chest pain.

Tremors

An involuntary quivering movement is known as tremors. This movement may be rhythmic and may feel like a to-and-fro type of movement. Often, tremors affect the arms, hands, face, voice, legs and head. Most commonly, tremors occur in the hands.

What causes tremors?

Tremors may be caused by many different health issues including Parkinson’s disease, liver failure or alcoholism. You may also experience tremors if you suffer from arsenic poisoning or mercury poisoning. Tremors are a common side effect of antidepressants, other medications and some supplements.

Heart Arrhythmia

Any problem with your heart rhythm is known as heart arrhythmia. This happens when the electrical impulses coordinating your heartbeats are not working correctly. It may feel like a racing heart beat or like your heart is fluttering.

What causes heart arrhythmia?

While some of the causes of heart arrhythmia are harmless, some are very serious. An electrolyte imbalance in the blood may cause an arrhythmia, while a more serious cause is coronary artery disease. Changes in blood pressure may also cause heart arrhythmia, along with some medications and supplements.

Prevagen side effects are rare, but reports of fainting, chest pains, tremors, heart arrhythmia and other reactions have surfaced from some users. To ensure your protection, always speak with a doctor before starting a new supplement, especially if you’re already taking medication, suffer from a medical condition, you’re pregnant, nursing or you’re under the age of 18.

Prevagen is a supplement formulated to improve or support memory. There is science behind the ingredient they've chosen and while there is no connection to weight-loss, if this is an issue you're dealing with it may be a good option.

Apoaequorin

Apoaequorin is a protein derived from glowing jellyfish[1]. It has become a popular ingredient in some dietary supplements for weight-loss.

What Is It Supposed To Do?

Apoaequorin is consumed to treat memory, mental function, and sleep quality.

Clinical Research

When the safety of apoaequorin[2] was tested, researchers concluded, “Based on the results of this study, the No Observed-Adverse-Effect Level (NOAEL) for Apoaequorin was determined as 666.7 mg/kg bw/day, the highest dose tested.” This study was published in Food And Chemical Toxicology : An International Journal Published For The British Industrial Biological Research Association. Nothing was noted for its ability to induce weight-loss.

White Rice Flour

White rice flour is made from milled rice. It is sometimes used as a replacement for wheat flour for those who are gluten intolerant.

What Is It Supposed To Do?

White rice flour contains dietary fiber and protein, which can be beneficial to general organ health. It also contains vitamins and nutrients like calcium and zinc.

Clinical Research

According to Arya Atherosclerosis, “Although there was no significant association between white rice intake and obesity factors in our study, more studies are necessary with larger population and better design.” Nothing was stated about white rice flour.

Acetic Acid

Acetic acid is the main chemical found in vinegar. It is typically manufactured in the United States, Europe, and Japan. It is sometimes used in physical therapy.

What Is It Supposed To Do?

Acetic acid is sometimes used to treat ear infections, head lice, nail fungus, and impetigo.

Clinical Research

According to a study published in Bioscience, Biotechnology, and Biochemistry, “In conclusion, daily intake of vinegar [the source of acetic acid] might be useful in the prevention of metabolic syndrome by reducing obesity.” No studies were available concerning its individual connection to weight-loss.

    I tried it for two weeks and noticed improved speed of memory, however it was more like taking extra caffeine.. I stopped taking for two weeks as I was experiencing dizzy spells.and didn’t notice any changes with memory. Today I tried again and had dizzy spell so I will not be taking again.

    I took it for awhile and noticed a difference right away. However, I developed a rash all over my stomach and thighs. After some research I found that the ingredient from jellyfish causes rashes in some people. I stopped the prevagen and the rash disappeared within a few weeks. It got a little better everyday starting from the first full day without the prevagen.

    57 year old female, good health, heart disease in family background – both sides. Been taking extra strength Prevagen for about 18 weeks. Memory, flow of sentences, focus, (without doubt) noticeably better. Sometimes I even remember what I’d dreamt overnight…in detail ! (Something I’ve not been able to do at all for at least the last 5 years!) Blood pressure, which has always hovered around 60-70 over 110, raised to 90 over 120 this last month.. Left foot has been swollen (edema) last 6 weeks, and (embarrassed to say) incontinence – a slight issue now and then, had become far from ‘slight’.

    I went off of Prevagen 6 days ago. Swelling down, blood pressure back to normal, and yes….incontinence issues waning. Go figure?! Damned if I take it, damned if I don’t. Will try cutting back to normal strength, or cutting back on dosages over next few months to see if I can reach a good midpoint between heart & bladder negatives vs. big mind positives.

    I had a head injury that left me with memory issues and heard about prevagen helping with this type of thing so I looked up all the info I could find on it and it sounded legit so I bought some and started taking it. The first dose I got a severe headache and stomach cramps but I wasn’t sure if it was all due to prevagen so I waited two days and tried again. More headaches and stomach cramps. I read where there side effects might subside with continued use and I really needed help with memory so I tried it for a whole week straight. The bad side effects never got better. I will have to keep looking for something else. If I can remember.

    My wife suffers from dementia.When I heard about Prevagen, I began giving it to her for memory loss. About 4 months later, she fell in the bathroom and broke her pelvis. Still, I didn’t associate her fall to the drug. But in the last week, I have noticed that she is irritable and somewhat more confused about where she is. I tried taking the Prevagen myself to see what near-term effect it may have. I suffer from 75% disability with combat-related PTSD. Last night, I began reliving bad war experiences and awakened in a cold sweat. I feel anxious and paranoid. Perhaps Prevagen is contributing to her confusion and anxiety as well. Sitting here typing this, I feel dizzy and somewhat confused. One thing for sure, I’m not giving her further doses of Prevagen and I am not taking it myself.

    Fisher

    Why don’t you just be straightforward and say that there is ZERO independent scientific research to support the claims that prevagen improves memory. Research conducted by the manufacturer is obviously biased and anecdotal evidence by fisherman Bob and homemaker Gladys is simply ludicrous– whether such reports are positive OR negative. Though I believe you mean well, your analysis is simply inadequate and does not convey any useful information.

    Prevagen appears to be a protein (apoaequorin). Usually proteins cannot pass thru the intestinal tract and get into the body without first being broken down to the constituent amino acids. How does Prevagen avoid this problem ? If it really enters the body as an intact protein, I would be concerned about allergic reactions ?

    Interesting how many comments here are based solely on bashing a product that they never tried. I am a mid 40’s some guy, athletic and eat healthy, and NO I am not being paid or compensated by anyone for my views here. I have been taking this product for quite some time and can say without question that I NEVER experienced any of the so-called “side effects” listed here. Those of you critics that haven’t taken it for an extended period of time, let alone taken it at all, have no say in the matter. In fact, I have noticed that since I STOPPED taking it I have a more difficult time with simple words or names, as well as thinking straight and my ability to focus. Personally I think the side affects from many other prescription drugs are far more harmful. You people really need to settle down and try it for real, and for more than just a few days or even weeks before you have any room to criticize this product.

    Hello, Joanna. Some dieters experienced side effects like high blood pressure, fast heartbeat, fainting, chest pains, dizziness, headache and tremors. Prevagen might not be recommended for someone with a history of those symptoms. Please consult your physician for more information.

    Prevagen is reportedly a protein extracted from jellyfish that improves brainpower. If you swallow one of these pills, the gastrointestinal tract will take this protein, break it up into its constituent amino acids, then absorb them, then the body will use the amino acids to build whatever proteins it feels it needs, not the original protein. If you are buying these pills at approximately $1.33 for 10 mg, you are paying approximately $6000 a pound for a protein supplement. Whey protein purchased at Wal-Mart or the general nutrition store is a much better buy!

    Marshal, while I was initially enthused about Prevagen I was becoming less so between the review article and the comments. Like the others said, they wondered if you were a Walmart employee. Laying that aside, you did give an option for comparison. Whey. I’ve been using that for some time because protein is supposed to help with type 2 diabetes, as I understand it. I think everyone who visits this page could help each other by researching this more and sharing their thoughts. That’s what I’m going to do.

    I am 92 and my problem was my short memory about dates, or remembering things going from one room to another. I decided to try Prevagen Feb 1,2015. I feel that it does help my short memory. I will know more after I have my regular Dr. check up this year, who should notice a difference in my vision or when I get my regular blood check up. Do you have any suggestions that I could request on my blood check up, like calcium or etc.???Appreciate your response.

    Hello Bertha. Please take the product with you to your appointment and advise your physician that you are taking it. They should be able to provide you with what you should request at your check up.

    I started taking Prevagen 35 days ago. My 83 year old mom has Dementia, I’m 60 and have been experiencing memory loss myself. I decided to try it after seeing your commercial and reading about it on the web. The first week I noticed a few changes. The second week I could recall dates and info more rapidly. The third week I remembered a phone number 6 days after hearing it only once in my life. The fourth week I felt younger, more focused, on task, I felt like this 60 year old was 25 again. It is a great feeling. I am worried about the stroke and heart attack warnings. I would like yo know how many people have experienced adverse effects in any way but especially stroke, seizures, heart attacks. My family doesn’t want me taking it because of the warnings. I don’t want to stop feeling like i’m 25 again. Please advise.

    By the second month of taking it I noticed Prevagen having some effect. It wasn’t like a lightning bolt and suddenly I rememebered everything better but there has been a definite increase in sharpness with my ability to pull up words when I was taking to someone. I was hoping it would work faster and I was hestitating on a second bottle but that’s how long it took for me to notice a change.

    I am 87 year old man that is physically and mentally degraded to some extent. I have been taking Prevagen Extra Strength for many months. I have continued to lose my memory! Has Prevagen helped? Who knows? Actually, I now think it is a VERY expensive product with really no actual proof of effectiveness. My wife is three years younger, and has very similar memory problems. She DOES NOT take the Prevagen and seems to have about the same memory problems that I have. Of course that is not proof of anything, but it does NOT verify that Pregagen is so very effective!

    It is likely that you have a fungus outbreak that is causing your mental decline, thereby over-riding the benefits of Prevagen. I recommend that you treat for fungus by implementing the Phase-one diet (search “Know the cause” by Doug Kaufman) then attack the fungus with anti-fungal foods and supplements.

    After seeing the amazing results in a friend, I asked her what she was taking and she told me about Prevagen. I had not seen her that Sharp in years! I have been taking it for about two months and have noticed a BIG difference in my cognitive ability and my memory. And, it didn’t take but one week to notice the difference. My recommendation is to buy one bottle and see for yourself – my guess is you will continue to take it. I’ve tried Omega 3’s and various fish oils and never noticed a difference. But, this product really works! My job performance has increase tremendously. Can’t say enough…even have my husband taking it now.

    I am interested in this product and was wondering what age Laurue is as i noticed the more negative responses were those who were older. i am in my 50’s. That may make a difference at what point u start using this. the younger the better result? just wondering.

    Hi Helen! I’m 63 and when I started trying Prevegen, I noticed a quicker recall in three days. My wife is 48 and she noticed a difference after 1 week. My favorite Aunt, who is 78 tried it and after 3 weeks, noticed the same effect that I had. It is absolutely worth a try. The the only thing you have to lose is a bad memory!

    My good friend started taking Prevagen a few months ago and has had a small miracle happen. She had a poor memory, and some learning disabilities that became embarrassing at her fast-paced job, but since taking it, she has noticed a huge difference. She feels so amazed by the results, she gave me a bottle. it is helping me with my post ‘chemo-brain’ fog. So much so that I splurged on a 3 month supply! I don’t go in easily for these sort of things, and sincerely don’t believe my success is the result of some placebo effect. I feel clearer in my thinking, my memory has improved, and you can’t make this stuff up!

    Al,

    While I’ve had the same concerns as you (+17 years of medical study involving pathology), there IS something odd happening to some consumers. I, for one, am very immune to the “placebo effect,” yet after trying this for 2 weeks, I suddenly woke up with name-recall. My son noticed this, because I had to ask him names constantly in the past. I wouldn’t have tried prevagen if I’d looked into the molecular structure first, however (a rare lapse in judgement)
    Do you think there’s a possibility that the EDTA is chelating something harmful with some people? I noticed another positive review from a scientist who used it for a trial but then stopped. It bewildered him as it does me.

    I always suspect nutritional supplements that come from exotic (like jellyfish) sources rather than from food-obtained nutrition. This allows the makers and distributors to make big bucks – something like the pharmaceutical companies? It sounds good, but it totally unavailable to someone like me on a very limited income. So I guess I’ll just have to die from my brain problems, which may or may not turn out to be Alzheimers.

    Amino acids cross the blood-brain barrier. Whole proteins do not. Any beneficial effect of apoaequorin is lost as soon as it is digested into amino acids like any other protein. It is simply untrue to claim that apoaequorin taken orally has any effect in the brain whatsoever.

    Jason says “Disregarding the sketchy clinical trials cited, the active ingredient is a protein compound (Aequorin) that gets broken down upon digestion into its component amino acids. While Aequorin certainly does bind calcium, even if it did survive digestion it is unlikely to pass the blood-brain barrier”

    Jason, being a bio-chemist, you DO know that ALL amino acids pass the blood brain barrier, don’t you?

    also, Prevagen does NOT contain EDTA.

    Thank you for the reviews. Upon taking prevagen, lots of energy, could stay focused, but could not sleep on this product. Independent studies would make it morally sound. Don’t you think?

    Having a degree in biochemistry, it’s my opinion that Prevagen does almost nothing more than the placebo effect. Disregarding the sketchy clinical trials cited, the active ingredient is a protein compound (Aequorin) that gets broken down upon digestion into its component amino acids. While Aequorin certainly does bind calcium, even if it did survive digestion it is unlikely to pass the blood-brain barrier and is more likely to bind calcium in the body first. At best it is a dose of protein and, by the looks of the other ingredients, EDTA, which is known to chelate (ie., bind) calcium and other metal ions like iron. This could probably pass the blood-brain barried, however higher doses of EDTA (2 g/kg) are known to be toxic to lab rats and the quantity of EDTA in Prevagen is unreported. If the purported effects of Prevagen work as a placebo for you or your loved one, by all means, continue. Though in my opinion the best way to promote healthy brain function is through intake of omega-3 fatty acids found in fish oils. These have been rigorously proven to lower risks of depression, suicide, Alzheimer’s, Parkinson’s, psoriasis, and even benefit pregnancies. These essential oils (EPA and DHA, specifically) can be taken as pills as well but do look for organic, ethically-farmed products.

    Thank you for your insite on this product. I too have studied biochemistry and feel the same should be said about the product. It is easy for some companies to claim the like, but not reviel the underlying…easy if one understands the language of chemisry…..so people ask questions and look up info before ypu buy anything!…..fish oils as well as primrose is great….

    Oh you of little faith. I have been taking it and I remember street names that eluded me and can contribute to conversations. That is so nice. My mom said since she has been taking it she is doing all her crossword puzzles without looking in the back for answers. My daughter has been taking it and reports that she doesn’t feel the need to close doors and straighten silverware and everything else in sight (OCD). Whatever it does, it’s helpful. Unless you have a nee-d and have tried it you should keep your negative input to yourself. You are a nay-sayer. Too much learning and not enough life experience or graciousness. Good day!

    Example: I was told a phone number once and did not write it down, 6 days later someone asked me if I new that persons phone number. It was as if I had written it down in my head. I have had 100’s of moments like that. I had written an order for a childs birthday party at my sons business, someone asked me 3 weeks later if I could call the childs mom. I had taken the order over the phone and had never met her. I had never even glanced at the order again in 3 weeks. I remembered her name, his name, his age and what color his cake was to be decorated in. It was amazing!! And my to do lists are a thing of the past. Its in my head ready for instant recall. I wouldn’t consider stopping this amazing medicine.
