- Won't fix a deficiency
what the evidence says
Ashwagandha, particularly root extracts like KSM-66, has accumulated a fair number of small human trials showing reduced perceived stress and cortisol and modestly improved sleep, with some industry funding in the mix. For stress-driven tiredness the signal is respectable; for fatigue with a physiological cause it fixes nothing. Long-term safety data remains thin and rare liver-injury reports exist.
Plain-language assessment of the human evidence. No cherry-picked citations.
