Every Score Backed
by Evidence

Our Efficacy Score distills complex research into a single number you can trust. Three weighted criteria, zero marketing influence.

Clinical Backing

40%

Is there real evidence this works? We check for human studies — not just lab tests on mice.

Bioavailability

30%

Can your body actually absorb it? A supplement is useless if it passes straight through you.

Third-Party Testing

30%

Has an independent lab verified what's in the bottle? We check for purity, potency, and contaminants.

We show you the tradeoffs other sites hide.

The Scientist Behind the Scores

Karol Vanessa Rojas Ramirez

Pancreatic Cancer Research Scientist, UMass Chan Medical School

I study pancreatic cancer at UMass Chan Medical School. But when I started looking into longevity supplements for myself, I was shocked by how hard it was to find honest information. Most review sites are just ads in disguise.

So I built AgeSmarter AI — applying the same research rigor I use in my lab to help people make smarter choices about what they put in their bodies. If a product can't survive real scientific scrutiny, it doesn't make our list.
