What is Prevagen?
Prevagen is a dietary supplement designed to support brain health and improve memory. It is marketed primarily for adults experiencing mild memory loss associated with aging. The key ingredient, apoaequorin, is a protein originally found in jellyfish, which the brand claims helps support cognitive function.
Unlike many other memory supplements, Prevagen stands out because of its unique formulation. It is available in different strengths, including regular and extra strength, and is widely accessible over the counter without a prescription. The supplement also includes vitamin D, which plays a role in overall brain function.
While Prevagen is popular among those seeking memory support, its effectiveness remains a topic of discussion. Many people turn to it as an easy, daily solution for cognitive wellness, but does it truly work? This review will explore that question.

How Does Prevagen Work?
There are 2 primary active ingredients in Prevagen. Vitamin D is important in nerve growth and synthesis in the brain. There are numerous Vitamin D receptors in the brain. In addition, it plays a neuroprotective role according to an article in Cureus [1]. Low Vitamin D can put you at risk for developing dementia.
Apoaequorin comes from a jellyfish, and many people believe it has an impact on memory and verbal learning. However, there’s not a lot of research as of yet. It’s a protein which binds to calcium, and this property may cause its brain-enhancing benefits. A study on adult and aging rats in Brain and Behavior found that this substance modulates fear memory [2].
Prevagen Ingredients – Are they Safe & Effective?
These are the primary active Prevagen ingredients:
Apoaequorin
– This is a protein taken from a glowing jellyfish. It has the ability to bind to calcium, which may be responsible for its role in brain health. This substance is thought to especially improve memory, but there’s only a small amount of research supporting this right now.
A study published in Advances in Mind and Body Medicine found that apoaequorin improved verbal learning in older adults[3].

Vitamin D
– This vitamin is made in your skin when you go out into the sunlight, and you can also get it from food. It protects the brain and, as highlighted in the Vitamin D guide, can reduce inflammation. In addition, it plays a key role in brain nerve synthesis.
There’s some evidence that low levels of this vitamin can lead to dementia. An article in Practical Neurology explored the cognitive consequences of Vitamin D deficiency [4].
Calcium
– This is an essential mineral that strengthens our bones and teeth, helps the blood clot, keeps the heart beating, and allows muscles to contract.
It plays a key role in the brain, affecting memory and neurotransmitter function. with additional benefits related to neuroprotection, as mentioned in the Cognigen Review.
An article published in General Pharmacology examined the role of calcium in brain aging [5].
Phosphorus
– This is a chemical element that is the second most common mineral in the human body. Some of it is found in the bones, and it supports bone health. There’s plenty of phosphorus in the brain, and it’s important in controlling many bodily processes.
A study in Frontiers in Aging Neuroscience found a correlation between low levels of phosphorus and cognitive impairment [6].

What Do the Prevagen Reviews Say?

However, some reviewers question its efficacy, pointing out the absence of robust scientific evidence and emphasizing that individual experiences may differ.
“I have been using Prevagen for about 5 months and SF180 Brain really works for my husband. It helps to improved focus and concentartion.”- hazel
One user from Amazon said, “I tried Prevagen for 6 months and was not sure if it worked. I stopped using it and did not notice any difference.”
Another user said, “I took Prevagen for 30 days, but unfortunately, I wasn’t able to determine if it actually improves anything. It may, but I don’t think I’m up to buying 3 months’ worth to find out. My expectations may simply be too high. It would be good if there were some sort of cognitive test that might provide some insight into improvement, but I imagine that is hard to develop because we are all different. I may try again at some future time.”
