Ashwagandha: every public report we counted

40 first-person reports from 4 websites: 13 said it helped, 22 said it did not help or made things worse, and 5 were mixed or too early to tell. None of these reports has been verified.

How much these count: reports are the lowest-weight evidence here, below any study. People who post are not a random sample, most take other treatments at the same time, and nobody checks the diagnosis. We have checked 0 of 40 for signs of marketing so far. How we weigh reports

Where these came from

Stress and anxiety

16 reports: 7 helped, 5 no effect or worse, 4 mixed or too early.

  • No effect Tried it for anxiety and noticed little difference; found L-theanine worked better. Mumsnet, 2024-10-18 (No dose or duration given.)
  • Helped Noticed a difference in anxiety on a KSM-66 product that also contained L-theanine, with magnesium alongside. Mumsnet, 2024-10-21 (Three other calming ingredients at the same time; unsure it would help severe anxiety.)
  • Mixed It helped her anxiety, but indigestion and stomach aches made her stop. Side effects: indigestion, stomach aches. Mumsnet, 2024-10-21 (No dose or duration given.)
  • No effect Says it did not really do anything for them. Mumsnet, 2025-09-07 (One-line report; no dose or duration.)
  • Helped Thinks it helped somewhat, but the effect was very subtle. Mumsnet, 2025-09-07 (The poster is unsure there was any effect at all.)
  • Helped Anxiety returning in perimenopause eased within two weeks; she has kept taking it for a couple of years. Mumsnet, 2025-09-07 (No dose given; perimenopause symptoms change on their own.)
  • Mixed Very helpful for anxiety when taken in the morning, but a night-time dose leaves them feeling worse. Side effects: feels worse when taken at night. Mental Health Forum, 2024-07-07 (The timing explanation is the poster's own theory.)
  • Worse After three to four months, a two-day stimulant-like episode then a crash; symptoms persisted after stopping at eight months. Side effects: stimulant-like episode, crash, palpitations, exhaustion. HealthUnlocked, 2026-04 (Long prior illness and many supplements make the cause hard to judge. Date approximate (six months ago).)
  • Mixed Over two to three months felt calmer and more focused, but had headaches and an irritable rebound hours after doses. Side effects: headache, irritability hours after dosing. LongeCity forum, 2014-05-28 (Also on a prescribed stimulant; one product was of unknown quality.)
  • Mixed KSM-66 eased anxiety and overthinking, but brought new pimples and more irritability. Side effects: acne, irritability. LongeCity forum, 2019-06-14 (Several other supplements taken together.)
  • Helped Anxiety largely lifted within two days of plain root powder; it returned when doses were missed and eased on restarting. Side effects: mild headache. LongeCity forum, 2013-02-17 (On two prescription drugs; later stopped the antidepressant abruptly, which complicates the picture.)
  • No effect About three months with no difference either when starting or after stopping. Mumsnet, 2026-09-19 (No dose given.)
  • No effect A high-strength product did nothing for them. Mumsnet, 2026-09-19 (One-line report.)
  • Helped Makes a big difference: less anxiety and stress, more energy. Mumsnet, 2026-09-19 (Short report; no dose or duration.)
  • Helped Makes a big difference: less anxiety and better sleep. Mumsnet, 2026-09-21 (Short report; no dose or duration.)
  • Helped Very helpful over two years; anxiety and poor sleep come back when she misses a few days. Mumsnet, 2023 (Exact post date not captured (thread from October 2023); also takes magnesium.)

Sleep and insomnia

7 reports: 3 helped, 4 no effect or worse, 0 mixed or too early.

  • Helped Started after stopping an antidepressant; slept better and felt calmer within days, later raising the extract dose from 300 to 600 mg. Mental Health Forum, 2022-11-17 (Early reports (days to two weeks); also on quetiapine and melatonin, and had just stopped sertraline.)
  • Worse Years earlier it had the opposite effect: worse insomnia, tension and strong anger hours after a dose. Side effects: worse insomnia, tension, anger. Mental Health Forum, 2022-11-19 (Recalled from years before; dose not given.)
  • Helped Two 150 mg capsules at night: sleeping better, with more vivid dreams; effect on stress hard to judge. Side effects: vivid dreams. Mental Health Forum, 2022-12-02 (About two weeks of use.)
  • Worse A bedtime dose left them awake from 4 am, detached and with a headache; it never worked for them. Side effects: early waking, headache, feeling detached. LongeCity forum, 2018-04-20 (Says L-theanine causes the same reaction.)
  • Worse Strange, vivid dreams left her unsettled and tired; it happened on two separate tries months apart. Side effects: very vivid dreams, waking unsettled and tired. Mumsnet, 2026-09-21 (Two short trials of one to two weeks.)
  • Worse After two nights felt odd and foggy-headed, like starting antidepressants years ago, and stopped. Side effects: feeling odd, foggy head. Mumsnet, 2025-09-12 (Only two doses.)
  • Helped Night waking improved; her Fitbit showed deep sleep up by at least a third. Mumsnet, 2026-01-22 (Consumer sleep trackers estimate deep sleep imprecisely; also tried magnesium.)

Testosterone and male fertility

2 reports: 0 helped, 1 no effect or worse, 1 mixed or too early.

  • Mixed More sex drive and better erections, but also more acne. Side effects: acne. LongeCity forum, 2014-02-13 (No hormone test; the poster reads the acne as a sign of higher testosterone.)
  • Worse A testosterone booster containing Sensoril left them dull, unmotivated and emotionally flat. Side effects: dullness, low motivation, emotional flatness. LongeCity forum, 2011-09-02 (Multi-ingredient product; the poster suspects the ashwagandha part.)

Other uses and general experience

  • Worse Says it sped up her hair loss, which did not recover; she will not use it again. Side effects: hair loss. HealthUnlocked, 2022 (Date approximate (shown as four years ago); hair loss with age has other causes.)
