Eight Hyped Compounds Failed to Extend Lifespan in a Major Mouse Study
Zusammenfassung
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.
Praktische Empfehlung
This study suggests that dose and timing matter enormously, and early lifespan results in mice often don't hold up.
