Ashwagandha

Dr. Andrew Huberman Strongly Recommends with Cycling Protocol

Huberman is the most comprehensive source on ashwagandha, discussing it across 8 videos covering stress management, cortisol reduction, hormone optimization, and recovery. His AMA #3 provides the most detailed protocol: 300mg twice daily, cycle off after 30 days, monitor via blood work. He groups ashwagandha with other adaptogens (Lion's Mane, Chaga) and notes it can indirectly support testosterone and libido. In his stress and anxiety episodes, he pairs ashwagandha with apigenin for evening cortisol management. Dr. Andy Galpin on his show emphasizes 'careful, data-driven application rather than prophylactic use.' Dr. Stacy Sims discusses ashwagandha for women's health, mood, and stress management.

Dr. Peter Attia Takes Personally for Sleep

His supplement list is 'dynamic and changes based on new data, personal biomarkers, and ongoing self-experiments.'

Dr. Mark Hyman Recommends for Adrenal Support

Hyman discusses ashwagandha across 6 videos, consistently recommending it as an adaptogenic herb for adrenal dysfunction, stress resilience, and cortisol management. He pairs it with rhodiola, Siberian ginseng, magnesium, and methylated B vitamins for adrenal recovery. He uses ashwagandha for sleep improvement (alongside magnesium, glycine, and melatonin), for managing the 'wired and tired' pattern of adrenal burnout, and for optimizing sexual health. In a conversation featuring Dr. Matthew Walker, he notes potential sleep benefits while cautioning against over-reliance on supplements.

…caffeine and alcohol I also recommend you add a number of supplements that can help support your adrenals vitamins and minerals just a good multivitamin vitamin C zinc uh B complex even with B5 some herbs can be helpful like siberian Gins sing riola Corps uh and these are great herbs that help balance your adrenal and stress response ashwagandha that's an artic herb that can help calm an overactive stress response and pl sleep all these things are really great to use together to help your body recover so if you're worried about your your adrenal stress response or if you've been told that you have adrenal burnout the good news is you can fix it…
