Ashwagandha Benefits for Women: What the Evidence Shows
The short answer: The ashwagandha benefits for women with the best evidence are modest gains in stress and sleep, while menopause data is thin and safety limits are real, including avoiding it in pregnancy.
- A review of 5 trials with 400 adults found a small sleep benefit (SMD -0.59), stronger at 600 mg a day or more for at least 8 weeks.
- Two small trials in 126 midlife women report lower menopause symptom scores, but the NIH says there is not enough evidence on menopause.
- The NIH says ashwagandha may be safe for up to 3 months and has been linked to rare cases of liver injury.

Ashwagandha benefits for women are real but modest, and the best support is for stress and sleep. A 2024 review of 9 trials with 558 people found lower scores on the Perceived Stress Scale than placebo, a drop of 4.72 points.

What are the ashwagandha benefits for women, and how strong is the evidence?
Stress and sleep have the most support, menopause symptoms have early and small trials, and hormone claims are mostly not backed up. Most trials were small, short and run in adults of both sexes, so the table names the people studied.
| Claimed benefit | Study and people | Result | How sure |
|---|---|---|---|
| Stress | Review of 9 trials, 558 people | Perceived Stress Scale 4.72 points lower | A larger review of 12 trials rated certainty low |
| Anxiety | Same review of 9 trials | Hamilton Anxiety Scale 2.19 points lower | NIH calls the evidence unclear |
| Cortisol | Review of 7 studies, 488 people | Cortisol 1.16 µg/dL lower, no clear change in perceived stress | Mixed |
| Sleep | Review of 5 trials, 400 adults | Small effect, SMD -0.59 | Stronger with insomnia, 600 mg or more, 8 weeks or more |
| Menopause symptoms | Trials of 66 and 60 women, aged 45 to 65 | Symptom scores 8.1 points lower vs 1.2 on placebo (larger trial) | Small trials; NIH says not enough evidence |
| Bone density | 12-week trial, 66 women | No difference from placebo | Exploratory outcome |
| Testosterone in women | Review of 23 trials, 1,706 adults | No significant rise (5.09 ng/dl) | Rose in men |
Does ashwagandha help with stress and anxiety?
A little, on average. The 2024 review of 9 trials found lower stress, anxiety and cortisol than placebo, and 4 of the trials reported mild to moderate side effects.
The picture is less tidy in other reviews. A 2022 review of 12 trials with 1,002 people aged 25 to 48 found lower stress and anxiety, but rated the certainty of the evidence low. A 2025 review found cortisol 1.16 µg/dL lower but no statistically significant change in perceived stress.
The NIH sums it up: “Research shows that some ashwagandha preparations may be effective for insomnia and stress. However, evidence is unclear about its effects on anxiety.”
Does ashwagandha help women sleep?
It may help a little. A 2021 review of 5 trials with 400 adults found a small but significant effect on sleep (SMD -0.59).
The effect was larger in adults diagnosed with insomnia, at doses of 600 mg a day or more, and with treatment lasting 8 weeks or more. The authors note that data on serious side effects are limited. A separate 2024 review of 5 trials with 254 people also found better sleep measures, with large differences between trials.
Does ashwagandha help with menopause symptoms?
Two small trials say yes, but the evidence is early. In a 2026 trial of 66 postmenopausal women aged 45 to 65, 600 mg a day for 12 weeks lowered Menopause Rating Scale scores by 8.1 points, against 1.2 on placebo.
Sleep scores improved by 5.2 points against 0.8, and body fat fell by 0.6% against a 0.03% rise. There was no difference in bone density, and no serious adverse events. A 2025 trial of 60 women aged 45 to 55 reported lower total scores and fewer hot flashes after 56 days.
Both were small, single-product trials, and the larger one was run at one center in India. The NIH says “There isn’t enough evidence to determine if ashwagandha is helpful for” conditions that include menopause and female infertility. Our perimenopause and menopause guide covers options with more research.
Does ashwagandha balance women’s hormones?
Not in the way marketing suggests. A 2026 review of 23 trials with 1,706 people found lower cortisol, but testosterone rose in men (57.43 ng/dl) and not significantly in women (5.09 ng/dl), and estradiol did not change in either sex.
The same review found no effect on TSH or T3 and a modest rise in T4 of 0.61 µg/dL. That is one reason people with thyroid conditions are told to ask a doctor first. The 2025 menopause trial reported changes in estradiol and progesterone, but no other trial here confirmed them, so we do not count them as a benefit.
What does ashwagandha not do?
The research does not show that ashwagandha is a weight-loss product, replaces hormone therapy or medicine, or helps fertility. The NIH lists female infertility among the conditions without enough evidence.
The 12-week menopause trial measured body fat, not weight loss, and the change was small. Do not stop a prescribed medicine for a supplement.
You may also see claims about athletic performance, thinking skills or blood sugar. The NIH lists athletic performance, cognitive function and diabetes among the areas without enough evidence, so we do not rate them here.
How much ashwagandha do the studies use?
Most studies use root extract at 300 to 600 mg a day. The 2022 review found the best stress effect at 300 to 600 mg a day, and the menopause and sleep trials above used 600 mg.
A 2026 safety review of 23 trials with 2,317 people covered doses from 125 to 600 mg a day, for up to 180 days. Products differ in strength and plant part, and the NIH notes they may contain root, leaf, or both. Dose in a trial applies to that product only.
Is ashwagandha safe for women, and who should skip it?
It appears safe for short use in most healthy adults, but some women should avoid it. The NIH says it “may be safe when taken in the short term (up to 3 months)” and that long-term safety is unknown.
Avoid it in pregnancy and breastfeeding, according to the NIH. It is also not recommended before surgery or with autoimmune or thyroid disorders, and it may interact with medicines for diabetes, blood pressure, seizures and thyroid, with sedatives and with immune-suppressing drugs.
Liver injury is rare but real. A 2026 scoping review of 13 publications covering 25 patients found injury typically developed after weeks of use, and most people recovered after stopping. It also reported one liver transplant and three deaths among people who already had cirrhosis. Cases commonly showed up as jaundice (yellow skin or eyes) and itching, so call a doctor if you notice either.
In a 12-month observational study of 191 adults, 18 mild side effects were reported and liver enzymes stayed in range, though there was no placebo group. The FDA says it “does NOT have the authority to approve dietary supplements for safety and effectiveness” before sale. Our supplements guide explains what that means.

Frequently asked questions
Is ashwagandha good for women over 40?
The trials in midlife women enrolled ages 45 to 65 and found lower menopause symptom scores, but they were small. The NIH says there is not enough evidence on menopause, so talk to your doctor before trying it.
How long does ashwagandha take to work?
In the studies, effects were measured after weeks, not days. Sleep benefits were larger with treatment of 8 weeks or more, and the menopause trials ran 56 days and 12 weeks.
Does ashwagandha cause weight loss in women?
No trial reviewed here tested it for weight loss. The 12-week menopause trial found body fat fell 0.6% against a 0.03% rise on placebo, a small change that we do not present as a weight benefit.
Can I take ashwagandha every day?
The NIH says it may be safe for up to 3 months and that long-term safety is not known. A 12-month observational study of 191 adults reported only mild side effects, but it had no placebo group.
