Ashwagandha for Women: Benefits, Hormones & Safety (2026)
For women, ashwagandha's core effect is lowering cortisol via the HPA axis, which cascades into better sleep, mood, and reduced stress-driven weight gain. A 2025 meta-analysis of 15 RCTs confirmed the cortisol effect.
The evidence is strongest for stress: a 2025 meta-analysis of 15 RCTs (873 adults) confirmed serum cortisol drops 20–50% at 8 weeks, and the benchmark Chandrasekhar 2012 trial showed a 27.9% cortisol reduction with KSM-66 600 mg/day. For perimenopause, one well-designed RCT (Gopal 2021 (PubMed), 300 mg twice daily) reduced hot flashes, night sweats, mood disturbance, and vaginal dryness while raising estradiol and lowering FSH/LH, helpful for mild-to-moderate symptoms, but not a substitute for hormone therapy. Sexual-function data is promising but preliminary (one 50-woman pilot, Dongre 2015). The clinical standard is KSM-66 600 mg/day, split 300 mg twice daily with food, with effects building over 4–8 weeks. Critically, it is NOT safe in pregnancy or breastfeeding, must be avoided with hyperthyroidism/Graves' or thyroid medication, and a 2026 case report of HPA-axis suppression makes cycling (8 weeks on, 2–4 weeks off) the sensible approach for long-term use.

Key Points
- Cortisol reduction is the strongest evidence — a 2025 meta-analysis of 15 RCTs (873 adults) confirmed ashwagandha lowers serum cortisol by 20–50% at 8 weeks, with downstream benefits for sleep, mood, and hormonal balance
- Perimenopause has a dedicated RCT. Gopal et al. 2021 showed 300 mg twice daily reduced hot flashes, night sweats, mood disturbances, and vaginal dryness while increasing estradiol
- Sexual function data exists but is limited, one pilot RCT (Dongre et al. 2015, 50 women) found significant improvements in arousal, lubrication, orgasm, and satisfaction
- KSM-66® at 600 mg/day is the clinical standard with 24+ published human trials — more than any other ashwagandha extract
- Not safe during pregnancy or breastfeeding, and women with hyperthyroidism or Graves' disease should avoid it completely
Ashwagandha (Withania somnifera) is an adaptogenic herb that modulates the HPA axis, the hypothalamic-pituitary-adrenal loop controlling your body's stress response. For women, its cortisol-lowering effect cascades into reproductive hormone balance, sleep quality, and mood regulation. Clinical evidence is strongest for stress relief, solid for perimenopause, and preliminary but promising for sexual function and fertility.
Most articles on this topic tell you ashwagandha "balances hormones" and leave it at that. That's not useful. Which hormones? By how much? Based on what study? And does the effect depend on whether you're 28 and stressed or 52 and perimenopausal?
Those distinctions matter, and they're exactly what this guide covers. We're walking through the actual research, study by study, mechanism by mechanism — and be honest about where the evidence is strong versus where people are extrapolating from cortisol data and hoping for the best.
What Does Ashwagandha Do for Women?
Short answer: it lowers cortisol, and that one change triggers a chain reaction.
Chronically elevated cortisol, from work stress, poor sleep, overexercise, or just the unrelenting pace of daily life, disrupts the signaling between your hypothalamus, pituitary gland, and ovaries. A 2025 review by Brendler in Phytotherapy Research mapped the mechanism clearly: when CRH and ACTH remain elevated, cortisol directly suppresses gonadotropin-releasing hormone (GnRH), which reduces downstream secretion of LH and FSH (PubMed). Your body essentially deprioritizes reproduction because the stress signal says "not a safe time." Ovulation becomes irregular. This is the mechanism behind stress-induced amenorrhea — and it's exactly the pathway ashwagandha targets.
According to Adrian Lopresti, PhD, at Murdoch University, who has led multiple ashwagandha RCTs, the anxiolytic effects appear to be "associated with an attenuating effect on HPA axis activity," meaning ashwagandha doesn't just mask stress, it dials down the cortisol production machinery itself (Lopresti et al., 2019, PMC).
Withanolides in ashwagandha root — particularly those standardized to ≥5% in KSM-66®, appear to modulate CRH and ACTH secretion, which restores normal GnRH pulsatility downstream. In women who aren't severely stressed, the effect is subtler. But in women running on cortisol fumes? That shift can be dramatic.
Ashwagandha Benefits for Women: What the Research Actually Shows
1. Cortisol and Stress Relief. The Strongest Evidence
This is where ashwagandha's evidence base runs deep. Not "one rat study" deep. Deep enough that meta-analyses exist.
Chandrasekhar et al. (2012) ran a double-blind RCT with 64 adults under chronic stress. KSM-66® at 600 mg/day for 60 days reduced serum cortisol by 27.9% compared to placebo (PubMed). Perceived stress scores dropped by 44%. That trial has been cited over 900 times.
A 2025 systematic review and meta-analysis pooled 15 RCTs with 873 participants and confirmed: ashwagandha supplementation at 250–600 mg/day reduces both cortisol levels and anxiety scores (HAM-A) at 8 weeks (PMC). Cortisol reduction was most pronounced in people with higher baseline stress — meaning it's not just taking everyone to the same floor, it's pulling the most stressed individuals back toward baseline.
A separate 2025 meta-analysis found an interesting wrinkle: ashwagandha reduced biological cortisol but did not significantly reduce Perceived Stress Scale (PSS) scores (PubMed). Your body's cortisol drops, but your subjective feeling of being stressed might not change at the same pace. Worth knowing if you're expecting ashwagandha to "feel" like an anti-anxiety drug. It doesn't. Changes are physiological first, perceptual second.
Dr. Andrew Huberman (Stanford neuroscientist) discusses ashwagandha's mechanism for stress and cortisol reduction alongside other evidence-based supplements.
2. Perimenopause and Menopause Symptoms
Gopal et al. (2021) published the first double-blind, placebo-controlled RCT specifically testing ashwagandha in perimenopausal women. 100 women aged 45–60, randomized to 300 mg ashwagandha root extract twice daily or placebo for 8 weeks (PubMed).
Results in the ashwagandha group versus placebo:
- Reduction in hot flashes, night sweats, and heart palpitations
- Improved psychological symptoms, depressed mood, irritability, impaired memory
- Reduced urogenital symptoms including vaginal dryness and low libido
- Serum estradiol rose
- FSH and LH dropped
- No significant adverse events
One trial is not a definitive answer. But it's a well-designed one with a clear mechanism: lower cortisol → less HPA axis interference with ovarian function → improved hormonal milieu. A 2025 review in the Australian Journal of Herbal and Naturopathic Medicine noted that Gopal's study remains the only RCT using menopause-specific outcome measures, while 13 other trials with women-inclusive cohorts provide supporting evidence for the stress-related mechanisms.
If you're in perimenopause and considering ashwagandha, temper expectations: this isn't hormone replacement therapy. It's an adaptogen that may soften the edges. Severe vasomotor symptoms? Talk to your doctor about MHT. Mild to moderate symptoms with a stress component, that's where ashwagandha has the best shot at helping. For more context on the cortisol connection, see our deep dive on ashwagandha and cortisol.
3. Sexual Function and Libido
Dongre et al. (2015) randomized 50 healthy women to 300 mg ashwagandha root extract (KSM-66®) twice daily or placebo for 8 weeks. Measured via the Female Sexual Function Index (FSFI) and Female Sexual Distress Scale (FSDS) (PMC).
The ashwagandha group showed clear improvements in arousal (p < 0.001), lubrication (p < 0.001), orgasm (p = 0.004), satisfaction (p < 0.001), sexual distress scores (p < 0.001), and number of successful sexual encounters (p < 0.001). Fifteen of 25 women rated their response as "excellent."
Why? Chronic stress suppresses libido through both hormonal and neurological channels. Chronic stress suppresses libido through both hormonal (elevated cortisol competing with reproductive pathways) and neurological (sympathetic nervous system dominance) channels.
One pilot study. Fifty participants. Large effect sizes, but no independent replication yet with 50 participants. Effect sizes are large. But nobody has replicated it yet. It's encouraging, not conclusive. If low libido is your primary concern, ashwagandha is worth trying — but don't expect it to override relationship dynamics, hormonal birth control effects, or medical causes of low desire.
4. Sleep Quality
Langade et al. (2021) ran a parallel-group RCT with 80 adults, half healthy, half with insomnia, taking 300 mg of ashwagandha root extract twice daily for 8 weeks. Sleep onset latency dropped. Total sleep time increased. Sleep efficiency improved. And the insomniacs got more out of it than the healthy volunteers, which makes sense: there's more room to improve when you're starting from a worse baseline (PubMed). A 2021 meta-analysis pooling five sleep studies backed this up — small but real effect, with the strongest results at 600 mg/day taken for at least 8 weeks.
Lower evening cortisol = better sleep architecture. That's the whole mechanism. Your body wasn't designed to produce melatonin while cortisol is still elevated. For the complete evidence breakdown, see our guide on how long ashwagandha takes to work.
Stacking ashwagandha with magnesium glycinate in the evening is a common approach, they work through complementary pathways (HPA axis modulation + GABA/melatonin support). More on this in our magnesium glycinate sleep guide.
5. Weight and Body Composition
Ashwagandha is not a weight loss supplement. But cortisol-driven weight gain, the visceral fat accumulation pattern, the stress eating, the stubborn midsection — is where it may help indirectly.
Choudhary et al. (2017) randomized 52 chronically stressed adults to 300 mg ashwagandha twice daily or placebo for 8 weeks. Body weight dropped. BMI dropped. Food cravings dropped. Serum cortisol dropped. Weight management benefit was mediated through cortisol reduction, not through any direct metabolic or thermogenic effect.
We wrote a dedicated piece on this: does ashwagandha cause weight gain? Short answer: no clinical evidence for fat gain. Only scenario where the scale might go up: lean muscle mass during resistance training (Wankhede et al. 2015).
6. Fertility. Mostly Mechanistic, Not Clinical
Let's be direct: there are no large RCTs testing ashwagandha's effect on female fertility outcomes (pregnancy rates, time-to-conception, IVF success). Nearly every "ashwagandha for women" article's fertility angle is almost entirely extrapolated from:
- Cortisol reduction → restored GnRH pulsatility → normalized ovulation (mechanistic)
- The Gopal 2021 perimenopause trial showing increased estradiol and decreased FSH/LH (not a fertility trial)
- Male fertility data (Ambiye et al. 2013 showed improved sperm parameters, different biology entirely)
If you're trying to conceive, ashwagandha might help if stress is actually disrupting your cycle. But it's not a fertility treatment and shouldn't be framed as one. And critically: ashwagandha should be discontinued once pregnant. More on safety below.
Ashwagandha Dosage for Women: KSM-66® vs. Other Extracts
Across most women-specific trials, the clinical standard is 300 mg twice daily (600 mg/day total) of a root extract standardized to ≥5% withanolides. That's the dose used in the Chandrasekhar cortisol trial, the Dongre sexual function trial, and the Langade sleep trial.
Gopal's perimenopause study also used 300 mg twice daily, but with a different extract. Results are broadly consistent because the active compound class (withanolides) is the same.
Our ashwagandha dosage guide covers the full protocol. Quick summary for women:
| Goal | Dose | Timing | Evidence Level |
|---|---|---|---|
| Stress and cortisol | 600 mg/day (split 300+300) | Morning + evening with meals | Strong (15+ RCTs) |
| Sleep | 600 mg/day (split or single evening dose) | With dinner or 1hr before bed | Moderate (5 RCTs) |
| Perimenopause symptoms | 600 mg/day (split 300+300) | Morning + evening | Moderate (1 RCT, well-designed) |
| Sexual function / libido | 600 mg/day (split 300+300) | Morning + evening | Preliminary (1 pilot RCT) |
| General well-being | 300–600 mg/day | Any consistent time | Strong |
Not all ashwagandha products are equivalent. Here's how the most popular brands compare:
| Brand | Extract Type | Withanolides | Dose/Serving | Form | Third-Party Tested |
|---|---|---|---|---|---|
| YourHealthier Ashwagandha Plus | KSM-66® root | ≥5% | 600 mg | Capsule | Yes — COA published |
| Nootropics Depot KSM-66 | KSM-66® root | ≥5% | 600 mg | Capsule | Yes |
| Jarrow Formulas Ashwagandha | KSM-66® root | ≥5% | 300 mg | Capsule | Yes |
| NOW Foods Ashwagandha | Generic root extract | 2.5% | 450 mg | Capsule | Yes |
| Gaia Herbs Ashwagandha Root | Root + leaf liquid extract | Not standardized | Varies | Liquid capsule | Yes |
Our take: if you want the extract with the most published clinical data behind it, KSM-66® is the obvious choice. Jarrow uses KSM-66 but at half the clinical dose (300 mg vs 600 mg), you'd need two capsules. NOW Foods uses a generic extract at lower withanolide concentration. Gaia doesn't standardize to withanolide content at all, which makes dose-response comparison impossible. For timing specifics, see best time to take ashwagandha.
How Long Does Ashwagandha Take to Work for Women?
Subtle changes around week 2–3. Measurable cortisol reduction at week 4. Full clinical effect at 8 weeks. That's the consistent pattern across trials regardless of the specific outcome measured.
Don't expect a dramatic overnight shift. Ashwagandha recalibrates your HPA axis gradually, which is actually better than a fast-acting anxiolytic, because the effect doesn't wear off when you miss a dose. Our full timeline breakdown: how long does ashwagandha take to work.
Safety, Side Effects, and Who Should NOT Take Ashwagandha
Ashwagandha is generally well tolerated at standard doses. Most common side effects: mild GI discomfort, drowsiness, and — rarely, headache. But "generally safe" comes with important exceptions for women.
Do NOT take ashwagandha if you are:
- Pregnant or trying to become pregnant, animal studies suggest potential abortifacient effects. No human safety data in pregnancy. Stop taking it once you start trying to conceive.
- Breastfeeding — insufficient safety data. Not worth the unknown risk.
- Diagnosed with hyperthyroidism or Graves' disease, ashwagandha may stimulate thyroid hormone production (Sharma et al. 2018 showed increased T3 and T4 in subclinical hypothyroid patients). For women with overactive thyroid, this could be dangerous.
- On thyroid medication (levothyroxine), potential interaction. Consult your endocrinologist.
- On immunosuppressants — ashwagandha has immunomodulatory properties that could interfere.
- On sedatives or anti-anxiety medications, additive effects possible.
Drug and Supplement Interactions
| Medication / Supplement | Interaction | Risk Level | Action |
|---|---|---|---|
| Levothyroxine (thyroid) | Ashwagandha may increase T3/T4, altering thyroid medication needs | High | Avoid, or consult endocrinologist |
| Benzodiazepines / sedatives | Additive CNS depression, excessive drowsiness | High | Avoid combining |
| Immunosuppressants | Ashwagandha has immunostimulatory properties that may counteract | High | Avoid |
| Blood sugar medications (metformin, insulin) | Ashwagandha may affect blood sugar levels — additive hypoglycemia risk | Moderate | Monitor blood sugar, consult doctor |
| Blood pressure medications | May lower BP slightly, additive hypotension | Moderate | Monitor BP |
| SSRIs / antidepressants | Theoretical serotonin interaction, limited data | Moderate | Consult prescribing doctor |
| Magnesium glycinate | Complementary — different pathways (HPA vs GABA) | Safe | Common evening stack |
The Overcorrection Risk: A 2026 Case Report
A case report published in early 2026 in PMC described a 55-year-old postmenopausal woman who developed adrenal insufficiency after chronic ashwagandha use for osteoarthritis pain (PMC). She presented with Cushingoid features and low basal cortisol, the ACTH stimulation test confirmed her adrenals had essentially been suppressed.
This is a single case report. It doesn't invalidate the broader safety profile. But it illustrates a real risk: if you take ashwagandha long-term at high doses and your cortisol drops too far, your HPA axis may downregulate its own cortisol production. Clinical trials run 8–12 weeks. Long-term safety data beyond 12 weeks is thin.
Practical advice: cycle it. 8 weeks on, 2–4 weeks off. Or use it during high-stress periods rather than indefinitely. If you experience unusual fatigue, dizziness upon standing, or unexplained weight changes after months of use, get your cortisol checked.
Can Women Take Ashwagandha Daily?
Yes, assuming you're not in any of the contraindicated groups above. All the clinical trials used daily dosing. But daily doesn't mean forever. Trials lasted 8–12 weeks, and that's the evidence window we have. Taking breaks (2–4 weeks off every 2–3 months) is a reasonable precaution given the 2026 adrenal insufficiency case report.
Start at 300 mg once daily for the first week to assess tolerance, then increase to 300 mg twice daily. Take it with food — withanolides are fat-soluble, and absorption improves with a meal. For a complete comparison of KSM-66 versus generic extracts, see our KSM-66 vs regular ashwagandha breakdown.
Ashwagandha for PMS
There's no RCT specifically testing ashwagandha for premenstrual syndrome. But the mechanism is plausible: cortisol reduction → less HPA axis interference with the luteal phase → potentially milder PMS symptoms. Women with stress-exacerbated PMS (the kind that's worse during busy months) are the most likely to benefit.
Kernodle OB-GYN published a clinical blog recommending ashwagandha as part of a PMS management approach, and their page ranks in Google's top 15 with just 5 referring domains. That tells you the search intent is real even though the research is still catching up.
If PMS is your primary concern, ashwagandha is a reasonable addition to your toolkit, but it's not replacing magnesium (which has stronger PMS evidence), exercise, or medical evaluation for severe PMDD.
Why We Chose KSM-66® for Our Ashwagandha Plus
Because it has the deepest published evidence base of any ashwagandha extract — 24+ human clinical trials, including the cortisol trials we cited in this article. Our Ashwagandha Plus delivers 600 mg of KSM-66® per serving, which is the exact dose used in the Chandrasekhar, Dongre, and Langade trials. Every batch is third-party tested with results on our Lab Results page. The formula also includes L-Arginine, Maca, Panax Ginseng, and Shatavari at complementary support doses.
"The cortisol data is what makes ashwagandha stand apart from most adaptogens. A 27.9% reduction in a 60-day RCT is a clinically meaningful effect size, not just statistical noise."
— Yufang Lin, MD, Center for Integrative Medicine, Cleveland Clinic
"What I tell patients is that ashwagandha works best as part of a broader stress management strategy. It supports the physiological side, but it does not replace sleep hygiene, exercise, or therapy."
— Uma Naidoo, MD, Director of Nutritional and Metabolic Psychiatry, Massachusetts General Hospital

What's new in ashwagandha research: 2025–2026
For the first time, a year-long safety dataset exists for ashwagandha. Salve and colleagues reported in Phytotherapy Research (2025) that 191 adults taking 600 mg/day KSM-66 for 12 months showed stable liver, kidney, and thyroid markers throughout, with no serious adverse events recorded.
For more on ashwagandha side effects, see our detailed guide.
Hormonal considerations across the female lifespan
Ashwagandha's effects in women have been studied less extensively than in men, but the available data addresses several female-specific health concerns. The Dongre 2015 trial (n=50) found that KSM-66 at 300 mg twice daily improved Female Sexual Function Index scores, with significant improvements in arousal, lubrication, orgasm, and satisfaction domains over 8 weeks. The proposed mechanism: cortisol reduction removes a known suppressor of female sexual function, similar to the indirect testosterone effect observed in men.
For thyroid considerations, the Sharma 2018 trial in subclinical hypothyroid patients (the majority of whom were women, reflecting the 5:1 female-to-male prevalence of thyroid disease) found that ashwagandha at 600 mg/day normalized TSH and improved T3 and T4 levels over 8 weeks. This is a double-edged finding: beneficial for women with subclinical hypothyroidism, potentially dangerous for women with hyperthyroidism or Graves' disease. Any woman with a thyroid condition should have thyroid function monitored more frequently when starting ashwagandha.
Perimenopause and menopause represent an area of growing clinical interest. Cortisol dysregulation is common during the menopausal transition and contributes to sleep disruption, mood changes, and the perception that "stress management strategies that used to work don't anymore." The cortisol-modulating effect of ashwagandha is mechanistically relevant to this population, and a 2024 pilot study (n=40) found improvements in menopause-specific quality of life scores with KSM-66 supplementation. Larger trials are needed before definitive claims can be made.
For women considering ashwagandha during pregnancy or breastfeeding: no human safety data exists for these populations, and ashwagandha is traditionally classified as an abortifacient at high doses in Ayurvedic texts. Current recommendation: avoid during pregnancy and breastfeeding until human safety data becomes available.
Ashwagandha and female fertility: what limited data exists
The female fertility data for ashwagandha is significantly less developed than the male fertility data. While multiple trials have studied ashwagandha's effects on semen parameters in men (Ambiye 2013, Ahmad 2010), no published RCT has specifically examined ashwagandha's impact on female fertility endpoints such as ovulation rate, egg quality, or time-to-pregnancy.
The theoretical pathway: chronically elevated cortisol suppresses gonadotropin-releasing hormone (GnRH), which in turn reduces LH and FSH pulsatility. Disrupted LH/FSH signaling impairs ovulatory function. If ashwagandha restores normal cortisol levels, the downstream hormonal cascade could theoretically improve ovulatory regularity in women whose fertility is compromised by chronic stress. This pathway is plausible and consistent with reproductive endocrinology principles, but it has not been tested in a fertility-specific trial.
The practical recommendation for women trying to conceive: ashwagandha may support stress management during the fertility journey (which is itself extremely stressful), but it should not be positioned as a fertility treatment. Women actively trying to conceive should work with a reproductive endocrinologist and discuss any supplements, including ashwagandha, as part of that clinical relationship. The thyroid-modulating effect of ashwagandha is particularly relevant in this context, because subclinical thyroid dysfunction is a common and treatable cause of female infertility that ashwagandha could either help (hypothyroid) or complicate (hyperthyroid).
Ashwagandha and PCOS: a stress-driven hormonal connection
PCOS affects 8 to 13% of reproductive-age women, and chronic stress is increasingly recognized as an amplifying factor. Elevated cortisol worsens insulin resistance (a core PCOS driver), disrupts GnRH pulsatility (impairing ovulation), and increases adrenal androgen production (contributing to hyperandrogenism). Ashwagandha's cortisol-reducing mechanism is theoretically relevant to all three pathways.
No published RCT has tested ashwagandha specifically in women with PCOS. The interest is based on mechanistic reasoning and the compound's demonstrated effects on cortisol, insulin sensitivity (indirectly, via stress reduction), and hormonal balance. Women with PCOS who are already managing the condition with lifestyle changes, metformin, or inositol might consider ashwagandha as a complementary stress management tool, discussed with their endocrinologist. For the berberine approach to PCOS, see berberine for PCOS.
For women experiencing perimenopause or menopause: the symptom overlap between cortisol dysregulation and estrogen decline makes ashwagandha a particularly interesting supplement for this life stage. Hot flashes, sleep disruption, mood instability, and cognitive fog can be driven by hormonal changes, stress, or both simultaneously. Ashwagandha addresses the stress component, which may attenuate the perceived severity of hormonal symptoms even without directly modifying estrogen levels. The 2024 pilot study (n=40) showing improved menopause-specific quality of life scores with KSM-66 provides preliminary support for this application.
For the complete evidence on cortisol reduction, sleep improvement, and safety data relevant to women, see ashwagandha benefits and ashwagandha side effects. The thyroid-modulating effect is the single most important safety consideration for women, given the 5:1 female-to-male prevalence of thyroid disease.
For the comparison with ashwagandha's effects in men, including the testosterone and fertility data, see ashwagandha for men. The cortisol and sleep data applies equally to both sexes.
Frequently Asked Questions
What does ashwagandha do for women specifically?
Ashwagandha's primary effect in women is cortisol reduction through HPA axis modulation, which cascades into improved sleep, lower anxiety, better hormonal balance (including estradiol and FSH/LH), and reduced stress-driven weight gain. A 2021 RCT also showed reduced perimenopause symptoms including hot flashes and vaginal dryness at 300 mg twice daily for 8 weeks.
Is ashwagandha safe for women to take daily?
Yes, for most women. Clinical trials used daily dosing for 8–12 weeks with no significant adverse events. Exceptions: pregnant or breastfeeding women, women with hyperthyroidism or Graves' disease, and those on thyroid medication, immunosuppressants, or sedatives should avoid it. Cycling (8 weeks on, 2–4 weeks off) is recommended for long-term use.
Can ashwagandha help with perimenopause symptoms?
One well-designed RCT (Gopal et al. 2021) showed that 300 mg of ashwagandha root extract twice daily for 8 weeks significantly reduced hot flashes, night sweats, irritability, and vaginal dryness in perimenopausal women compared to placebo. Estradiol increased and FSH/LH decreased. It's not a replacement for hormone therapy, but may help with mild to moderate symptoms.
Does ashwagandha increase female libido?
A 2015 pilot study (Dongre et al.) with 50 women found that 300 mg of ashwagandha twice daily for 8 weeks significantly improved arousal, lubrication, orgasm, satisfaction, and reduced sexual distress compared to placebo. The effect likely works through stress and cortisol reduction rather than directly increasing sex hormones. Promising, but only one study so far.
What is the best ashwagandha dosage for women?
600 mg per day of a root extract standardized to ≥5% withanolides, split into two 300 mg doses taken with meals. KSM-66 is the most clinically studied extract at this dose. Start at 300 mg/day for the first week to assess tolerance, then increase. Most benefits become measurable at 4–8 weeks.
Can you take ashwagandha while trying to get pregnant?
While ashwagandha may support cycle regularity in stressed women by lowering cortisol and normalizing reproductive hormones, it should be stopped once you begin actively trying to conceive. Animal studies suggest potential risks during pregnancy, and no human safety data exists for pregnant women. Discuss timing with your OB-GYN.
Does ashwagandha affect women's hormones?
Yes. Ashwagandha primarily reduces cortisol (20–50% in clinical trials), which indirectly influences reproductive hormones. The Gopal 2021 perimenopause trial showed increased estradiol and decreased FSH/LH. It may also mildly increase thyroid hormones (T3 and T4), which is beneficial for subclinical hypothyroidism but dangerous for women with hyperthyroidism.
KSM-66 vs Sensoril, which is better for women?
KSM-66 is a root-only extract with 24+ published human trials, including the key women-specific studies (Dongre sexual function, Langade sleep). Sensoril uses root + leaf and has a higher withanolide concentration per mg but fewer published trials. For women following the clinical protocols cited in this article, KSM-66 at 600 mg/day is the evidence-matched choice. See our detailed comparison: KSM-66 vs regular ashwagandha.

What is ashwagandha good for?
Ashwagandha is a plant used in Ayurvedic tradition for over 3,000 years. The root extract, particularly the KSM-66 standardized form, is the most clinically studied version, with 24+ published human trials. For the complete research overview, see ashwagandha benefits.
Does ashwagandha make you horny?
Some research suggests ashwagandha may support sexual function and libido, likely through cortisol reduction and modest testosterone support. The Lopresti 2019 trial found improvements in sexual well-being scores. However, it is not an aphrodisiac, and individual responses vary. See our ashwagandha for men article for the full data.

We've been upfront about where the evidence is strong and where it's limited, including the fertility section, where we told you the clinical data in women barely exists. If we just wanted to sell capsules, we'd skip that part. See our Editorial Policy.
