Eight Hyped Compounds Failed to Extend Lifespan in a Major Mouse Study
Graded Preliminary — lifespan study of eleven compounds in genetically heterogeneous UM-HET3 mice across three sites, yet an animal model with no human data, so not shown in people.
Animal study. Findings may not carry over to people, which is why the grade is capped at Preliminary.

This study suggests that dose and timing matter enormously, and early lifespan results in mice often don't hold up.
The NIA's Interventions Testing Program tested eight compounds across three lab sites in genetically diverse mice. None extended lifespan. That includes astaxanthin, alpha-ketoglutarate, pioglitazone, atorvastatin-telmisartan, and others with prior promising results. Some compounds previously shown to work at different doses or start ages didn't replicate under new conditions. Two drugs actually shortened lifespan in female mice.
