America’s 3 Most Popular Memory Supplements Were Put to the Test
In the last few months we tested America’s 3 favorite memory supplements — Prevagen, Neuriva and BrainXCell — in the lab and in real patients, and the results didn’t match what the ads promise.
My experience with brain health and memory
Nice to meet you, I’m Petter Attia, a specialist in brain health and cognitive aging and, over the last few months, I’ve conducted a complete analysis of the 3 best-selling memory supplements in the United States: Prevagen, Neuriva and BrainXCell.
Despite their popularity, some of these products delivered results that were far less consistent than expected.
What exactly did we test?
In the last few months we took the 3 best-selling memory supplements in the US – Prevagen, Neuriva and BrainXCell – and put them under a complete, independent review. They’re the same products people search for under “Prevagen reviews”, “Neuriva reviews” and “BrainXCell reviews”, but instead of relying on marketing, we analyzed them in the lab and tested them in real patients over 50 to see which one is the best memory supplement for memory in 2026.

How we evaluated each supplement
Step 1 – Lab & science
We analyzed ingredients, dosage and scientific evidence, and ran lab tests to verify what is actually inside each formula.
Step 2 – Real patients
We followed real patients before and after using each supplement, measuring memory, focus and day-to-day cognitive changes.
That’s why we focused our tests on people over 50.
Transparency comes first
Before anything else, I want to make it clear that our team does not profit from these evaluations.
Our commitment is to transparency and to the mission of helping as many people as possible reduce the impact of cognitive decline and improve memory in a healthy, natural way, using supplements that actually deliver what they promise – not just what they advertise.
The wrong supplement today can cost you years of frustration tomorrow
Now you have the opportunity to make an informed choice and invest in what truly delivers results. A supplement chosen only because of marketing doesn’t just cost money – it costs time, energy, and, in many cases, years of frustration with promises that never come true.
Don’t be misled by pretty labels and empty promises.
Watch the brief presentation I prepared below, where I show, in practice, the real results of each supplement and share the stories of our patients after using each product. Discover what truly makes the difference and take the next step toward a healthier, calmer memory.
