Antioxidants and senolytics are frequently compared as alternatives, but they address completely different phases of cellular aging. Antioxidants act upstream: reducing oxidative DNA damage that triggers senescence induction. Senolytics act downstream: eliminating cells that have already crossed the senescence threshold. Both are necessary for comprehensive anti-aging strategies.

If I take high-dose antioxidants, do I still need senolytics?

Yes. No level of antioxidant protection completely prevents senescence induction — it reduces the rate. And decades of accumulated senescent cells before starting your antioxidant protocol still require clearance.

Can antioxidants interfere with senolytic activity?

Theoretically, antioxidants taken on senolytic burst days might blunt the ROS-mediated senolytic activity of EGCG or piperlongumine. BCL-2 inhibitor senolytics (fisetin, quercetin) are not ROS-dependent and are not affected by antioxidants.
