Detailed Answer
Ashwagandha is well-supported as a cortisol-lowering adaptogen with buy-in from 4 of 5 experts.
Huberman is the strongest advocate, calling it "highly effective at reducing cortisol" at 300mg twice daily. He pairs it with apigenin for evening cortisol management. Critical caveat: he advises cycling off after 30 days and monitoring via blood work — the only expert to specify a cycling protocol.
Attia includes it in his personal nighttime routine alongside glycine and magnesium threonate. Johnson takes it in his morning 111-pill protocol. Hyman recommends it for adrenal dysfunction alongside rhodiola.
Huberman cautions that ashwagandha can indirectly affect testosterone and thyroid — "should be approached with caution, cycled appropriately, and monitored via blood work."
