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.
What is Prevagen?
First off, Prevagen is an over-the-counter dietary supplement containing the active ingredient Apoaequorin.  Take one each morning and it supposedly improves memory, promotes clearer thinking and a sharper mind.  The product doesn’t contain synthetics – impressive.
Prevagen was first introduced in 2007 by Quincy Bioscience. 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.  “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.  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.  Furthermore, we have some issues with the numerous customer complaints, especially relating to adverse effects.   
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.
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.
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.

- 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.
- 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.
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.
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.  Usually, fainting only lasts a few minutes.
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.  Even some medications and supplements may cause chest pain.
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.
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 is a protein derived from glowing jellyfish. 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.
When the safety of apoaequorin 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.
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 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.
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.
