If you’ve spent any time on social media or searched for natural ways to manage PCOS, you’ve probably come across ashwagandha.
This popular herbal supplement is often promoted for reducing stress, balancing hormones, improving fertility, and even helping with weight management.
But does the research actually support these claims?
The short answer is: maybe — but the evidence is still limited.
While ashwagandha has shown promising benefits for stress management, sleep, and blood sugar regulation, there have been very few studies in women with PCOS specifically.
Most of what we know comes from research in other populations, meaning there are still important questions to answer before we can confidently recommend it for everyone with PCOS.
As a registered dietitian who specializes in PCOS, I’m often asked whether ashwagandha is worth taking. The answer depends on your symptoms, your health history, and your goals. Like many supplements, it isn’t a magic solution, and it isn’t the right choice for everyone.
In this guide, I’ll walk you through what ashwagandha is, what the current research says about its potential benefits and risks for PCOS, who may want to avoid it, and how to decide whether it’s worth discussing with your healthcare provider.
What Is Ashwagandha?
Ashwagandha (Withania somnifera) is a medicinal herb that has been used for centuries in traditional Ayurvedic medicine.
Native to India, the Middle East, and parts of Africa, it is a small shrub with yellow flowers and red-orange berries. Traditionally, the plant’s roots have been used for medicinal purposes.
Today, ashwagandha is most commonly sold as a dietary supplement in the form of capsules, powders, liquid extracts, gummies, and teas. You may also see it referred to as Indian ginseng or winter cherry, although it isn’t actually a type of ginseng.
Ashwagandha is best known as an adaptogen — a term used to describe herbs that are thought to help the body adapt to physical and emotional stress. While the concept of adaptogens comes from traditional medicine, research on how they work in humans is still evolving.
Because of its potential effects on stress, sleep, blood sugar, and inflammation, ashwagandha has become an increasingly popular supplement for a wide range of health concerns, including PCOS.
Although early research is promising, it’s important to remember that most studies have not been conducted specifically in women with PCOS.
Throughout this article, we’ll look at what the evidence tells us and where more research is still needed.
What Does the Research Say About Ashwagandha for PCOS?
If you’ve searched online for information about ashwagandha and PCOS, you’ve probably seen claims that it can balance hormones, improve fertility, reduce stress, and even help with weight loss.
While some of these claims are based on promising research, it’s important to know that there have been very few studies evaluating ashwagandha specifically in women with PCOS.
Most of the available research has been conducted in adults with chronic stress, men, people with diabetes or metabolic conditions, or animal models.
This doesn’t mean ashwagandha can’t be helpful for women with PCOS, it simply means we need to interpret the current evidence with caution.
Here’s what we know so far.
May Help Manage Stress
Living with PCOS can be stressful. Between navigating frustrating symptoms, managing appointments, and trying to sort through conflicting nutrition advice online, it’s no surprise that many women with PCOS experience higher levels of stress and anxiety than women without the condition.
Although stress doesn’t cause PCOS, chronic stress can make it more difficult to manage. It may affect sleep quality, eating habits, physical activity, and overall quality of life.
Some research also suggests that chronically elevated cortisol (the body’s primary stress hormone) may contribute to insulin resistance, although this relationship is complex and still being studied.
Ashwagandha is best known for its potential role in stress management. Several randomized controlled trials have found that it can reduce perceived stress and lower cortisol levels in adults experiencing chronic stress.
In one study, adults who took 600 mg of ashwagandha daily for eight weeks experienced significant improvements in both perceived stress and cortisol levels compared with those taking a placebo.
While these studies weren’t conducted specifically in women with PCOS, reducing stress may still be meaningful for women whose symptoms or overall well-being are affected by chronic stress.
What this means for you: If stress or anxiety is affecting your daily life, ashwagandha may be worth discussing with your healthcare provider.
Just remember that it should complement — not replace — other evidence-based stress management strategies like regular physical activity, good sleep habits, counselling, or mindfulness practices.
May Support Blood Sugar Regulation
Insulin resistance is estimated to affect up to 75% of women with PCOS and plays a central role in many of the condition’s symptoms.
When the body’s cells become less responsive to insulin, the pancreas produces more insulin to compensate. Over time, elevated insulin levels can contribute to increased androgen production, irregular menstrual cycles, weight gain, and a higher risk of developing type 2 diabetes.
Some early research suggests that ashwagandha may improve insulin sensitivity and help the body regulate blood sugar more effectively.
Scientific reviews and small clinical studies have reported improvements in blood glucose and insulin sensitivity, particularly in people with diabetes or other metabolic conditions.
Although these findings are encouraging, there is currently very little research examining whether ashwagandha has the same effects in women with PCOS.
What this means for you: If improving insulin resistance is one of your goals, the strongest evidence still supports regular physical activity, eating balanced meals that include fibre and protein, maintaining a healthy sleep routine, and taking medications when appropriate.
Ashwagandha may eventually prove to be a helpful addition for some women, but the research isn’t there yet.
May Help Reduce Chronic Inflammation
Many women with PCOS experience chronic low-grade inflammation, which may contribute to insulin resistance and increase the risk of long-term health conditions such as type 2 diabetes and cardiovascular disease.
Ashwagandha contains naturally occurring compounds with anti-inflammatory properties. Laboratory studies, animal research, and some human studies suggest that it may help reduce inflammatory markers in the body.
However, there is very little research evaluating whether these anti-inflammatory effects translate into meaningful improvements for women living with PCOS. While the early findings are promising, more research is needed before we can draw firm conclusions.
What this means for you: Ashwagandha may have anti-inflammatory properties, but it’s important to remember that overall lifestyle habits — such as eating a varied, nutrient-rich diet, staying physically active, getting enough sleep, and not smoking — remain the foundation of reducing chronic inflammation.
Can Ashwagandha Improve Fertility?
You may have seen claims online that ashwagandha can improve fertility in women with PCOS. At this time, there isn’t enough high-quality research to support this claim.
Some studies have explored ashwagandha’s effects on fertility in men, while others suggest that reducing stress may have indirect benefits for reproductive health.
However, there is currently no strong evidence showing that ashwagandha improves ovulation, increases pregnancy rates, or treats infertility in women with PCOS.
If you’re trying to conceive, it’s always best to discuss a care plan and supplements with your healthcare provider or fertility specialist.
The Bottom Line on the Research
Current research suggests that ashwagandha may offer benefits for stress management and could potentially support blood sugar regulation and reduce inflammation.
However, most of this evidence comes from studies that did not include women with PCOS.
Until larger, well-designed clinical trials are available, it’s best to think of ashwagandha as a supplement with promising — but still limited — evidence rather than a proven treatment for PCOS.
For some women, it may become one helpful piece of a comprehensive PCOS management plan. For others, it may not be the right choice.
The decision should always take into account your symptoms, medical history, medications, and goals, ideally in partnership with your healthcare team.
Does Ashwagandha Increase Testosterone Levels?
This is a common question around ashwagandha and PCOS and unfortunately, it’s one that doesn’t yet have a clear answer.
Several studies have found that ashwagandha can increase testosterone levels in men. For example, an 8-week randomized controlled trial found that healthy men taking ashwagandha experienced increases in both testosterone and DHEA-S compared with those taking a placebo.
So, does that mean the same thing happens in women with PCOS?
At this point, we simply don’t know.
There have been very few studies evaluating the effects of ashwagandha in women, and even fewer in women with PCOS. This means we can’t assume that the increase in testosterone seen in men also occurs in women. However, we also can’t rule it out.
This uncertainty is particularly important because many women with PCOS already have elevated androgen levels.
Androgens are often referred to as “male hormones,” but women naturally produce them too. In PCOS, higher-than-normal levels of testosterone and other androgens can contribute to symptoms such as:
- Acne
- Unwanted facial or body hair (hirsutism)
- Scalp hair thinning or hair loss
- Irregular menstrual cycles
- Difficulty ovulating
Because of the lack of research in women with PCOS, some healthcare providers recommend caution with ashwagandha if blood tests have shown elevated testosterone or DHEA-S levels, particularly if symptoms of hyperandrogenism are already difficult to manage.
That doesn’t necessarily mean ashwagandha is unsafe or should be avoided by everyone with PCOS. Rather, it highlights the importance of taking an individualized approach instead of assuming that every “natural” supplement is appropriate for every person.
What this means for you: If your testosterone or DHEA-S levels are elevated, or you’re experiencing symptoms such as acne, excess facial hair, or scalp hair loss, it’s a good idea to discuss ashwagandha with your healthcare provider before starting it.
Until more research is available, we simply don’t know whether ashwagandha has the same hormone-related effects in women that it appears to have in men.
How to Use Ashwagandha for PCOS
If you and your healthcare provider decide that ashwagandha is an appropriate supplement for you, you may be wondering how much to take and when to take it.
While there isn’t a recommended dosage specifically for women with PCOS, most clinical studies have used daily doses ranging from 300 to 600 mg of a standardized ashwagandha root extract.
These doses have generally been well tolerated and have been associated with improvements in stress and sleep in adults.
Some studies have used higher doses, but this doesn’t necessarily mean that more is better. As with many supplements, taking the lowest effective dose is often a sensible place to start.
When Should You Take Ashwagandha?
There isn’t strong evidence that taking ashwagandha at a particular time of day makes it more effective. Instead, the most important factor is taking it consistently.
Some people prefer taking it in the morning, while others find it fits better into their evening routine.
If you notice that ashwagandha makes you feel sleepy, taking it in the evening may be more comfortable. On the other hand, if it causes digestive upset, taking it with a meal may help reduce stomach discomfort.
Choose a time that works well for your routine, as consistency is more important than the exact timing.
Choosing an Ashwagandha Supplement
Not all supplements are created equal. Because natural health products aren’t regulated as strictly as prescription medications, the quality and amount of active ingredients can vary between brands.
When choosing an ashwagandha supplement, look for one that:
- Uses a standardized root extract.
- Clearly lists the amount of ashwagandha per serving.
- Has been third-party tested for quality and purity, when possible.
- Is purchased from a reputable manufacturer.
Although capsules are the most common form used in research studies, ashwagandha is also available as powders, liquid extracts, gummies, and teas.
The best option is the one you’ll take consistently and that fits your preferences and lifestyle.
How Long Does It Take to Work?
Ashwagandha isn’t a supplement that works overnight. In most clinical trials, participants took it consistently for 6 to 8 weeks before improvements in stress, sleep, or other outcomes were measured.
If you decide to try ashwagandha, it’s important to have realistic expectations. While some people may notice benefits sooner, others may not notice any difference at all.
A Few Practical Tips
If you’re trying ashwagandha for the first time, consider these tips:
- Start with the lowest effective dose rather than assuming more is better.
- Take it consistently each day to give it the best chance to work.
- Take it with food if you experience stomach upset.
- Let your healthcare provider know about any supplements you’re taking, especially if you’re pregnant, have thyroid disease or an autoimmune condition, or take prescription medications.
Remember, supplements work best when they’re used to complement — not replace — the foundations of PCOS management, including balanced nutrition, regular physical activity, quality sleep, stress management, and any medications recommended by your healthcare team.
Side Effects and Who Should Avoid Ashwagandha
Ashwagandha is generally considered to be well tolerated when taken at the doses used in clinical studies. However, like any supplement, it isn’t completely risk-free.
Understanding the potential side effects and knowing when to avoid it can help you make a more informed decision.
Common Side Effects
Most people tolerate ashwagandha without significant problems, but some may experience mild side effects, particularly when first starting the supplement or taking higher doses.
The most commonly reported side effects include:
- Upset stomach
- Nausea
- Diarrhea
- Vomiting
- Drowsiness
These side effects are usually mild and often improve over time. Taking ashwagandha with food may help reduce digestive discomfort.
Less Common but Important Safety Considerations
Although uncommon, there are a few additional safety concerns worth knowing about.
Liver Health: Rare cases of liver injury have been reported in people taking ashwagandha supplements.
While these events appear to be uncommon, it’s important to stop taking the supplement and seek medical attention if you develop symptoms such as yellowing of the skin or eyes, dark urine, severe fatigue, or persistent abdominal pain.
Thyroid Function: Some research suggests that ashwagandha may increase thyroid hormone levels.
While this may not be a concern for everyone, it could be problematic for people with hyperthyroidism or those taking thyroid medication. If you have a thyroid condition, speak with your healthcare provider before taking ashwagandha.
Medication Interactions: Ashwagandha may interact with certain medications, including medications used to treat diabetes, high blood pressure, thyroid disorders, and conditions requiring immunosuppressive therapy.
Always let your healthcare provider or pharmacist know about any supplements you’re taking.
Who Should Avoid Ashwagandha?
Ashwagandha may not be appropriate for everyone. It’s best to avoid taking it — or speak with your healthcare provider first — if you:
- Are pregnant or breastfeeding.
- Have elevated testosterone or DHEA-S levels, or significant symptoms of hyperandrogenism.
- Have hyperthyroidism or another thyroid condition.
- Have an autoimmune disease, particularly if you’re taking immunosuppressive medications.
- Have liver disease or a history of liver problems.
- Take medications that could interact with ashwagandha.
A Note on Supplement Safety
One misconception about herbal supplements is that they’re automatically safe because they’re “natural.” In reality, herbs contain biologically active compounds that can affect the body in many of the same ways as medications.
That’s why it’s always a good idea to let your healthcare provider know about any supplements you’re taking — even if they’re available over the counter.
This is especially important if you have PCOS, as many women are managing other health conditions or taking medications that could interact with certain supplements.
Bottom line: Ashwagandha appears to be safe for many healthy adults when used appropriately, but it isn’t the right choice for everyone.
Understanding both the potential benefits and the potential risks can help you decide whether it’s a good fit for your individual health needs.
FAQ About Ashwagandha and PCOS
Can Ashwagandha Cure PCOS?
No. Ashwagandha cannot cure PCOS.
PCOS is a complex hormonal condition influenced by genetics, insulin resistance, inflammation, and lifestyle factors. While some supplements, including ashwagandha, may help support certain symptoms, they do not address the underlying condition itself.
Ashwagandha may play a supportive role for some people, particularly in areas like stress, sleep, or blood sugar regulation, but it should not be viewed as a standalone treatment for PCOS.
How Long Does It Take to See Results from Ashwagandha?
Most clinical studies have used ashwagandha for 6 to 8 weeks before measuring outcomes like stress, sleep quality, or blood sugar markers.
Some people may notice subtle changes sooner, while others may not notice any difference at all. Supplements can affect everyone differently, and response is not guaranteed.
If you do choose to try ashwagandha, consistency over several weeks is important before deciding whether it’s helping you.
Can Ashwagandha Help With Weight Loss in PCOS?
There is no strong evidence that ashwagandha directly causes weight loss.
Some indirect effects — such as reduced stress or improved sleep — may support healthier habits that contribute to weight management over time. However, these effects are not the same as a direct fat-loss effect.
For PCOS-related weight management, the strongest evidence still supports a combination of:
- balanced nutrition patterns
- regular movement (especially resistance training)
- adequate sleep
- insulin-sensitizing medications when appropriate
Is Ashwagandha Safe During Pregnancy or Breastfeeding?
No. Ashwagandha is not recommended during pregnancy or breastfeeding.
It has traditionally been used in some cultures for its uterine effects, and there is not enough safety data to confirm it is safe during pregnancy or lactation. Because of this uncertainty, it is generally avoided in these life stages.
Can I Take Ashwagandha With Other PCOS Supplements?
It depends on the supplement combination and your individual health history.
Ashwagandha is often taken alongside supplements like inositol, vitamin D, or omega-3 fatty acids, but there is limited research on how these supplements interact together.
If you are taking multiple supplements — or medications — it’s important to check with a healthcare provider or pharmacist to ensure the combination is appropriate and safe.
Does Ashwagandha Balance Hormones in PCOS?
Ashwagandha is sometimes marketed as a “hormone-balancing” supplement, but this is an oversimplification.
There is no strong evidence that it directly balances reproductive hormones in women with PCOS.
However, it may indirectly influence certain pathways — such as stress response and blood sugar regulation — that can interact with hormonal health.
More research is needed before we can make clear conclusions about its effects on sex hormones in PCOS.
Summing It Up: Is Ashwagandha Right for You?
Ashwagandha is a well-studied herbal supplement with a long history of use in traditional medicine, particularly for supporting stress and overall resilience.
When it comes to PCOS, the research is still in its early stages.
There is some promising evidence suggesting that ashwagandha may help with stress, sleep, and possibly blood sugar regulation. These effects could be meaningful for some women, especially since stress and metabolic health often play a role in PCOS symptoms.
However, it’s important to keep the limitations in mind. Most of the available research has not been conducted in women with PCOS specifically, and we still don’t fully understand how ashwagandha may affect reproductive hormones in this population.
There is also uncertainty around its potential impact on testosterone levels, which may be particularly relevant for women who already have elevated androgens.
Because of this, ashwagandha is best thought of as a potentially helpful but not essential supplement for PCOS management.
If you’re considering trying it, the most important step is to take an individualized approach. Your symptoms, blood work, medications, and overall health history all matter. What may be supportive for one person may not be appropriate for another.
For most women with PCOS, the strongest foundation for symptom management still includes:
- balanced, consistent eating patterns that support blood sugar stability
- regular movement, including strength training where appropriate
- adequate sleep
- stress management strategies that feel realistic and sustainable
- medical treatment when needed
Supplements like ashwagandha may fit into that bigger picture for some people — but they work best when they are truly supplemental, not central.
If you’re unsure whether ashwagandha is right for you, it’s always a good idea to discuss it with a registered dietitian, pharmacist, or healthcare provider who understands your full health picture.
