Prevagen supplement ReviewPrevagen Overview

What do you know about calcium? If you’re like most people, the first thing that probably pops into your mind is bone health. And while that is certainly true, recent research demonstrates that calcium ions are also important in the brain. However, with neurons, it’s not a problem of too little calcium.

Neural signaling that underlies memory is dependent on calcium. When glutamate (a excitatory neurotransmitter) binds to specialized receptors on neurons, channels open and allow calcium to enter, which turns on signaling cascades that lead to the formation and maintenance of memory. Unfortunately, too much calcium is toxic to cells and leads to the initiation of apoptosis, which is a type of cellular suicide.

Based on this knowledge, researchers at the University of Wisconsin-Madison have developed a supplement that is designed to combat dangerous levels of calcium in neurons using a unique jellyfish protein called aqoaequorin.

How Does Prevagen Work?

Apoaequorin jelly fishApoaequorin is a small, calcium-binding protein isolated from a species of jellyfish that lives in Washington’s Puget Sound. We have our own versions of calcium-binding proteins, but they decrease as we age. This leads to increased intracellular calcium. As mentioned above, this can interfere with neuronal function and may even be neurotoxic.

The version of apoaequorin in the Aequorea victoria jellyfish is nearly identical to the proteins encoded in our genome. The makers of Prevagen claim that taking an apoaequorin supplement protects neurons from calcium-induced toxicity.

They performed studies on cell cultures to demonstrate that Prevagen prevented cell death during calcium overload. Although these experiments are striking, it is not completely clear whether the apoaequorin in the oral supplement actually makes it into the brain.

focus and increased memory Prevagen Benefits

The makers of Prevagen claim that regular use of their supplement will protect memories, help you remember more, and promote greater focus and clearer thinking. The underlying reason given for all these benefits is decreased neuronal death.

Although some question the usefulness of an oral supplement, Quincy Bioscience, the company that makes Prevagen, has conducted double-blind, placebo-controlled studies in 40-90 year old subjects. They claim that participants who had previously reported experiencing memory problems showed significant improvements in learning, short-term memory, and word recall following a three-month, once-a-day Prevagen (10 mg) regimen. It is important to note that these results were not published in a peer-reviewed scientific journal. They are, however, available as a PDF on the Prevagen website.

reviewsPrevagen Reviews

Prevagen was voted the #1 Brain Health Supplement in the 2011 Vity Awards, which are sponsored by Vitamin Retailer magazine. This award is based on U.S. health food store retailers’ feedback. Reviews posted online by actual customers seem to be mixed.


Glen von Skal (G. Skal “rpcv”) wrote the following review on 5/10/2010:

I originally purchased prevagen for memory issues. I have used it for about 40 days or so and my memory might have improved marginally. What I have noticed is that the frequency of my migraine headaches and intensity has dropped by about 50%. I also happen to feel more at easy, more relaxed. Is it due to Prevagen? Not sure, but it certainly coincides with the time frame I have been taking it.

Heather Fleming hung in there and noticed a difference after 3 months. She described her experience in a 4/13/2011 review:

I have taken Prevagen for 4 months now. At first I was skeptical because nothing seemed to change. However by the third month, not only did I begin to remember and use words I haven’t used in years, but now I can multi-task again too (without distraction)…….like I use to in my 20’s, 30’s, and 40’s. I find if I decide to skip a day or two (now) without taking them, I notice a set-back in the clarity of my everyday thinking, and in the amount of work I can accomplish. I am back online purchasing and reviewing stocks in the stock market, and making great judgment calls once again (because that deeper thought process is back). Don’t give up after a month or two. It takes a while to rebuild and replace the damaged cells in your brain and to get the synapse firing at a quicker pace once again. It helps in more ways than just memory!

Neutral or negative

Marilyn Inturias actually experienced increased headaches while taking Prevagen, and wrote about it on on 7/1/2010:

I really don’t know what to say, I’ve been taking this for about 30 days now and I haven’t noticed a difference in my memory etc… in fact the only change in me was headaches, every night exactly 8 hours after taking it. I quit taking it and the headaches ceased! Maybe it’s a coincidence but the price was a lot to get headaches!! Jeesh!

Craig Sandager complained about the cost on on 7/31/2009:

This product is way way to expensive. Try getting down around $20.00/mo. and you might actually sell a few bottles, but of course the manufacturer probably demands a 100% profit so could you take a 5% profit and sell it for $21.00. Seriously, I have used this product and the bang is simply not as big as the buck.

Prevagen Dosage & Directions

A bottle of Prevagen contains 30 capsules (10 mg each) and is enough for a  month. There is also a Prevagen Pro formulation available that has four times the amount of apoaequorin (40 mg). The makers of Prevagen recommend taking 1 capsule per day in the morning, with or without food.

In addition to the active ingredient (apoaequorin), the capsules contain white rice flour, sodium chloride (salt), and magnesium stearate. They are free of gluten, yeast, dairy products, corn, sugar, artificial coloring, preservatives, and flavoring. They are also made in the U.S.A.

Prevagen Side Effects

There is little discussion of side effects on the company’s website, but the most commonly reported complaint in user forums and reviews is headache. Others include dizziness, nausea, allergic reactions, and even increased libido. Toxicity studies showed Prevagen to be safe, and no serious adverse effects have been reported in humans.
