Short answer
Yes, for cortisol. Ashwagandha is a potent cortisol reducer, usually dosed at 300mg twice daily, and it is used for stress, sleep and adrenal support. Andrew Huberman, who doses it that way on his own show, also says to cycle off after 30 days.
Ashwagandha is worth taking.

Ashwagandha lowers cortisol, and that is the reason it is used for stress and anxiety. Andrew Huberman, on his own show, says the research literature shows it can reduce cortisol levels.
Huberman calls ashwagandha a potent cortisol reducer and doses it at 300mg twice daily, paired with apigenin in the evening. He also sets a cycling rule: come off after 30 days and check blood work.
It turns up in nighttime routines with glycine and magnesium threonate, in a 111-pill morning stack taken for anxiety and sleep, and in advice on adrenal dysfunction, paired with rhodiola. None of the sources on the record argues against it for stress. The partial views are about how to use it, such as taking it later in the day and not before exercise.
Ashwagandha can reach testosterone and thyroid. Use it with care, cycled and watched with blood work.
