What is Prevagen?

Prevagen is a line of nootropic organic supplements which promise to enhance overall brain health, improve memory, sharpen thinking, elevate mental focus, and raise overall cognitive performance. The manufacturer also claims the supplements can help with mild mental impairment.


What is the Science of Prevagen?

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 [2].

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 [3].

What Does Prevagen Contain?

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 [4].
  • 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 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 [5].
  • Calcium – This is an essential mineral which strengthens our bones and teeth, helps the blood to clot, keeps the heart beating, and allows muscles to contract. It plays a key role in the brain, affecting memory and neurotransmitter function. An article published in General Pharmacology examined the role of calcium in brain aging [6].
  • Phosphorus – This is a chemical element which 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 [7].

How Do I Take Prevagen?

All of the Prevagen products for memory have a recommended dose of one capsule per day. The exception is the Neuro Shake, where you mix a packet with 8 ounces of water and drink it once a day.
