Expert Positions
The Verdict
4 of 5 experts actively use or recommend ashwagandha. Huberman is the strongest advocate with specific dosing protocols and cycling recommendations. Attia takes it personally as part of his nighttime routine. Johnson includes it in his Blueprint stack. Hyman recommends it for adrenal support and stress resilience. Patrick has no direct coverage.
Quick Protocol
Dosage
300mg twice daily (600mg total) per Huberman. Other experts do not specify doses in analyzed videos. Start at 300mg to assess tolerance.
Form
No expert specifies KSM-66 vs Sensoril in the analyzed summaries. Both are standardized extracts commonly available. KSM-66 is a full-spectrum root extract; Sensoril uses both root and leaf.
Timing
Evening for cortisol management and sleep support (Huberman, Attia). Johnson takes it in the morning. Huberman specifically pairs it with apigenin in the evening for cortisol reduction.
Key Findings
- Ashwagandha is classified as a cortisol-lowering adaptogen — Huberman calls it 'highly effective at reducing cortisol' at 300mg twice daily.
- Huberman explicitly recommends cycling off ashwagandha after 30 days, noting it should be monitored via blood work — the only expert to specify a cycling protocol.
- Ashwagandha can indirectly support testosterone and libido, but Huberman cautions it 'should be approached with caution' for hormonal effects.
- Attia takes ashwagandha as part of his nighttime routine alongside glycine and magnesium threonate — suggesting he views it primarily as a sleep support compound.
