Prevagen 90.3%

Quick Overview

Prevagen is a nutritional supplement that claims to support brain wellness and provide memory boost. It is formulated with apoaequorin, touted safe and uniquely supportive of brain function. This dietary supplement first became available to consumers in 2007 and became an immediate success, and the manufacturer claims that since that time over 1 million people have tried Prevagen. 


Today, Prevagen is available in more than 50,000 stores across the United States and online, and is promoted as an award-winning supplement for memory support. Let’s see what lies beneath the surface and how it stacks up against other top brain enhancement solutions today. 



The three different strengths of Prevagen contain 10 mg, 20 mg, or 40 mg of apoaequorin, a protein found in glow-in-the-dark jellyfish known as Aequorea victoria. Each version of the product contains 50 mcg or 2,000 units of vitamin D3 as well. 


How Does It Work?

The most commonly reported benefits of this supplement are linked to improvements in mild memory loss associated with aging. Use of Prevagen for 90 days is recommended to fully gauge its effectiveness. 


Apoaequorin is known as a calcium-binding protein, with research linking calcium to brain health as well as memory. An imbalance of calcium in brain nerve cells called neurons, according to WebMD, might have a role in cell aging, damage, as well as disrupted signals between them. 


Dosage and Side Effects

The recommended dosage for apoaequorin depends on what it is being used for. For cognitive function, the recommended dosage is 10mg of apoaequorin (Prevagen, Quincy Bioscience) daily for 90 days. For memory, the recommended dosage is the same, taken daily for the same 90 days. For sleep quality, too, the recommended dosage is the same for the same number of days. 

Prevagen asserts that its main ingredient apoaequorin has undergone extensive safety testing. User reports and available evidence, however, paint a different picture, showing nausea, dizziness, headaches, as well as cardiovascular issues such as hypertension, chest pain, and irregular heartbeat especially when taken in doses higher than 10mg per day. 


Final Word

Because of the high number of vendors selling Prevagen, there tend to be differences in the cost of the three products, ranging from $40 to $179. This is a rather steep price to pay even at the minimum of $40, particularly as there’s an abundance of competing nootropic supplements that offer delightful formulas, high-performance ingredients, and just really obvious benefits. Prevagen is too controversial for its own good, too, so you might be better off veering away from controversy and going for a nootropic whose performance and user feedback speak for itself.
