ashwagandha

Ashwagandha is discussed mainly as an adaptogen that may reduce stress and cortisol. Key points:

• Potential effects: Studies discussed in the episodes found lower cortisol and anxiety in stressed adults; one summary cited cortisol reductions of roughly 14.5–27.9%. 1 2
• Timing and amount discussed: Huberman described 250–300 mg doses later in the day, sometimes twice daily, and advised avoiding it before exercise. He also cautioned against prolonged daily use, suggesting a break after a short course. 3
• Cautions: Check suitability and safety with a healthcare professional; effects and risks can vary. The episodes give differing cycling suggestions, so they don’t establish one universal schedule. 4 5
