Supplementing with the antioxidant pyrroloquinoline quinone (PQQ) modestly extends the lifespan of age-accelerated mice while improving their strength.  


Examining Evidence for the Cognition-Enhancing Potential of the Antioxidant Astaxanthin

The antioxidant astaxanthin significantly extends male mouse lifespan, and human research suggests it may help prevent age-related cognitive decline.
