What the research says about ashwagandha
Educational summaries of published research on ashwagandha (Withania somnifera); not product-specific claims. AOR Gandha-600's claims are the traditional Ayurvedic and adaptogen uses authorized under NPN 80023482.
High-concentration root extract cut cortisol and stress scores
In a 60-day RCT, adults with chronic stress taking a high-concentration full-spectrum ashwagandha root extract (300 mg twice daily) showed significantly reduced stress-scale scores and serum cortisol versus placebo, with only mild, comparable adverse effects in both groups.
Human RCTStandardized extract lowered morning cortisol and DHEA-S
A 60-day placebo-controlled trial of a standardized ashwagandha extract (240 mg/day) in stressed adults found significant reductions in the Hamilton Anxiety Rating Scale and greater drops in morning cortisol and DHEA-S than placebo, consistent with a moderating effect on the HPA axis.
Human RCTDose-response: 600 mg/day cut cortisol more than 250 mg/day
An eight-week trial comparing ashwagandha root extract at 125 mg/day and 300 mg twice daily (600 mg/day) against placebo found both doses reduced Perceived Stress Scale scores and serum cortisol, with the higher dose producing the larger effect.
Human RCTRoot extract plus piperine reduced anxiety and boosted serotonin
In a 60-day RCT, a standardized ashwagandha root extract (500 mg/day with piperine) significantly improved Perceived Stress Scale and GAD-7 anxiety scores versus placebo, alongside reduced salivary cortisol and increased urinary serotonin.
Human RCTMeta-analysis: large reductions in anxiety and stress scores
Pooling 12 randomized trials (1,002 participants), a systematic review found ashwagandha supplementation significantly reduced both anxiety and stress scores versus placebo, though the authors rated the certainty of evidence as low and called for further high-quality studies.
Meta-analysisReduced anxiety scores in a pooled analysis of insomnia/anxiety trials
A systematic review and meta-analysis of five RCTs found Withania somnifera significantly reduced Hamilton Anxiety Scale scores as well as several objective sleep parameters compared with placebo.
Meta-analysisSix weeks of a standardized extract improved non-restorative sleep
In 150 adults with non-restorative sleep, a standardized ashwagandha extract (120 mg/day for 6 weeks) produced a 72% improvement in self-reported sleep quality versus 29% for placebo, plus gains in actigraphy-measured sleep efficiency and total sleep time.
Human RCTRoot extract improved sleep in both healthy adults and insomnia patients
An 8-week, placebo-controlled trial in 80 participants found ashwagandha root extract significantly improved sleep-onset latency, sleep efficiency and anxiety scores, with larger gains in those with diagnosed insomnia than in healthy sleepers.
Human RCTMeta-analysis confirms a modest, real effect on overall sleep
Pooling five RCTs (400 participants), a systematic review found a small but significant benefit of ashwagandha extract on overall sleep, most pronounced in adults with diagnosed insomnia, at doses of 600 mg/day or more for 8 weeks or longer.
Meta-analysisReviewed for a role in thyroid, adrenal and reproductive hormone balance
A 2023 review of ashwagandha's endocrine effects concluded it can support thyroid secretory function and normalize adrenal activity via the HPA axis - the same hormone-modulating action is precisely why safety and dosing need care in people with existing thyroid conditions.
ReviewImproved thyroid hormone levels in subclinical hypothyroidism
In a placebo-controlled pilot trial, 8 weeks of ashwagandha root extract (600 mg/day) significantly improved TSH, T3 and T4 levels in adults with subclinical hypothyroidism - a finding that also underscores why people with a thyroid condition should use ashwagandha only under medical supervision.
Human RCTA real published case of thyrotoxicosis after ashwagandha use
A case report documented a healthy woman who developed thyrotoxicosis after increasing her ashwagandha dose for fatigue; symptoms resolved after she stopped the supplement. The authors cite animal data showing ashwagandha can raise thyroid hormone levels, supporting caution in anyone with a thyroid condition.
Case reportEight weeks of use showed no thyroid, liver or kidney abnormalities
An 8-week randomized, placebo-controlled safety study in 80 healthy adults found no clinically significant changes in hematology, liver enzymes, kidney markers, or thyroid hormone profile with ashwagandha root extract (300 mg twice daily); no adverse events were reported.
Human RCT12-month observational study supports long-term safety
In 191 adults followed for a full year, standardized ashwagandha root extract was associated with only 18 mild, self-resolving adverse events and no clinically significant abnormalities in liver, kidney or thyroid-function testing.
Long-term safety studyWell tolerated even at higher (1000 mg/day) doses over a month
Eighteen healthy men taking 1000 mg/day of standardized root extract for four weeks showed no adverse changes in liver, kidney or thyroid-function tests, supporting tolerability at doses above a typical single-capsule serving.
Human studyInternational clinician guidelines rank ashwagandha above rhodiola for anxiety
A joint WFSBP/CANMAT taskforce of 31 international psychiatry researchers graded ashwagandha as 'modestly supported' (Grade A evidence) for anxiety disorders, while rhodiola was not supported for mood disorders in the same review of nutraceuticals and phytoceuticals.
Clinical guideline reviewCompared against other classic adaptogens for brain inflammation
A mini-review comparing Withania somnifera, Rhodiola rosea, Eleutherococcus senticosus and Schisandra chinensis found all four adaptogens share anti-neuroinflammatory mechanisms, modulating inflammatory signaling pathways implicated in stress-related brain conditions.
ReviewAshwagandha's antidepressant mechanisms set against other adaptogenic herbs
A 2026 review comparing ashwagandha with two other botanicals used for mood support highlighted ashwagandha's distinguishing combination of cortisol-lowering and brain-derived neurotrophic factor (BDNF) support among converging monoaminergic and anti-inflammatory pathways.
ReviewWithanolides: the steroidal lactones behind ashwagandha's activity
An updated phytochemistry review catalogues withanolides - roughly 300 known C-28 steroidal lactones - as the primary bioactive class in Withania somnifera, with withaferin-A and withanolide-D the most studied for their molecular targets.
ReviewA 3,000-year-old Rasayana examined through a modern lens
A comprehensive ethnopharmacology review traces ashwagandha's documented use across classical Ayurvedic texts (Charaka Samhita, Susruta Samhita) as Balya (strength-promoting) and Rasayana, cross-referenced against its modern phytochemical and clinical-trial evidence base.
ReviewA comprehensive look at ethnopharmacology and toxicology
A wide-ranging review of Withania somnifera's geographical distribution, traditional use, phytochemistry and pharmacology also surveyed toxicological considerations, concluding the plant shows potent bioactivity across anti-inflammatory, neuroprotective and cardio-protective domains.
ReviewNot all extracts are equal: bioavailability varies by withanolide-glycoside content
A crossover pharmacokinetic study comparing four standardized ashwagandha extracts found the extract richest in withanolide glycosides (35%) delivered dramatically higher blood levels of total withanolides than extracts standardized only to withanolides, showing that extraction method affects real-world dosing.
Human PK study125 mg/day confirmed as the lowest clinically validated stress dose
An 8-week, dose-ranging RCT comparing 125, 250 and 500 mg/day of an aqueous root-and-leaf extract found all three doses safely reduced chronic stress on the Perceived Stress Scale, confirming 125 mg/day as an effective lower-bound dose.
Human RCTMeta-analysis finds a dose-response relationship for cortisol reduction
Pooling 23 randomized trials (1,706 patients), a 2026 meta-analysis found ashwagandha reliably lowered cortisol and raised serotonin, with subgroup analysis suggesting the size of the effect scales with the withanolide content of the dose used.
