If you’ve kept up with the health and wellness scene over the past few years, you already know there is always some new “must-try” supplement making the rounds.
Whether it’s apple cider vinegar, coconut oil, collagen powder or whatever is currently taking over your social feed, people love trying the thing that promises to fix stress, sleep, energy and maybe your entire personality by next Tuesday.
Ashwagandha has all the markings of being the latest health craze, but it is not exactly new. This root has been used in Ayurvedic medicine for hundreds of years, long before it started showing up in gummies, capsules, powders and lattes.
Here are a few things you may not know about ashwagandha:
With more people looking for alternative ways to manage stress, improve sleep and feel a little less like they are running on fumes, ashwagandha’s potential effects are obviously appealing.
The main talking points – better sleep, lower stress and mostly feeling calmer – are things many people would like to improve. After all, when was the last time someone told you their life felt peaceful and they were beautifully well-rested?
The average adult may be open to giving ashwagandha a try, but the “biohacker” crowd has really helped push it into the spotlight. It fits right in with the idea of making small changes, tracking how you feel and then deciding if the thing is actually doing anything.
Nothing wrong with that, as long as we remember that a supplement is not the same thing as sleep, therapy, food, movement or fixing the 42 things on your calendar that are making you stressed in the first place.
Short answer: some promising things, but not enough to act like it is a miracle root.
Ashwagandha has been studied most often for stress, anxiety, sleep and general well-being. The National Center for Complementary and Integrative Health notes that some research suggests ashwagandha may help with stress and sleep, but many studies are small, short-term or use different extracts and doses.
That matters because “ashwagandha” on one supplement label may not be the same as “ashwagandha” on another. Different products may use the root, leaf or a standardized extract, and the amount of active compounds can vary quite a bit.
There is also a difference between traditional use and strong clinical evidence. Centuries of use are worth paying attention to, but they do not replace well-designed human studies with larger groups of people and good safety tracking.
There has been some research into an anti-inflammatory effect after taking ashwagandha, but we still need more research to understand how meaningful this is in real life. I always like when a supplement has early science behind it, but early science is not the same thing as a guarantee.
The strongest conversations around ashwagandha are related to stress and sleep. A review published in the Journal of Herbal Medicine found that ashwagandha supplementation was associated with reduced stress and anxiety in several clinical trials, though the authors also noted that more high-quality studies are needed.
Some research also suggests ashwagandha may improve sleep quality, especially in people dealing with stress or poor sleep. That does not mean it should replace good sleep habits, but it may be one tool for some people.
These potential benefits include:
There are also claims that ashwagandha helps with inflammation, brain health, immune function and even cancer prevention. This is where I would take a very large step back.
Some of those effects have been studied in test tubes, animals or very small human trials, but that is not the same as proving a supplement prevents or treats disease. As noted by Medical News Today, many possible benefits still need stronger research before we can make clear conclusions.
This may seem like a pretty random list, but many of the possible effects of ashwagandha come back to stress regulation. Ashwagandha is often called an adaptogen, meaning it may help the body respond to physical or emotional stress.
One hormone that gets a lot of attention here is cortisol, often called the “stress hormone.” Cortisol is not bad, by the way; we need it to wake up, respond to stress and keep blood sugar and inflammation in check.
The problem is when stress is constant and cortisol patterns get out of whack. That can sometimes show up as poor sleep, irritability, cravings, headaches, fatigue or feeling like one small inconvenience is absolutely going to send you over the edge.
Ashwagandha may help lower perceived stress and may influence cortisol levels in some people. But, and this is an important but, it is not a free pass to ignore sleep, nutrition, alcohol intake, caffeine overload or a lifestyle that is basically one long emergency.
Taking ashwagandha is not the only way to support healthy stress levels. In fact, it probably should not be the first thing we reach for if the basics are being ignored.
We know that chronic stress is linked with poorer sleep, higher blood pressure, digestive symptoms, changes in appetite and mood concerns. We also know that sleep, movement, enough food, social support and mental health care are not nearly as marketable as a supplement bottle, which is annoying but true.
Your body was designed to release stress hormones to help you respond to danger. That made sense when the danger was a predator, not 117 unread emails, traffic, a sick kid and a meeting that could have been an email.
This is where ashwagandha may be supportive for some people. It may help take the edge off, but it is not going to do the hard work of changing the things that keep pushing your nervous system into overdrive.
Ashwagandha has also been studied for male sexual health, fertility and testosterone levels. This is one area where the research is interesting, but still not something I would oversell.
One clinical study found that ashwagandha supplementation was linked with increased testosterone levels, improved sperm count and better reproductive hormone markers in men. Other studies have looked at strength, muscle mass and exercise recovery, with some promising results.
Could some of this be related to stress reduction? Possibly.
Stress can affect sleep, hormones, libido and overall energy, so it would not surprise me if lowering stress helped in more ways than one. Still, men dealing with low testosterone, infertility or sexual health concerns should be evaluated by a health care provider rather than trying to supplement their way through it.
This is the part that often gets skipped online, because safety warnings do not make for very exciting TikToks.
Ashwagandha is not recommended during pregnancy, and it should generally be avoided while breastfeeding unless your health care provider specifically says otherwise. There is concern that ashwagandha may increase the risk of miscarriage, which is reason enough to be cautious.
People with autoimmune conditions, such as lupus, rheumatoid arthritis, multiple sclerosis or Hashimoto’s disease, should also check with a clinician before taking it. Ashwagandha may stimulate the immune system, which is not always what you want with autoimmune disease.
It may also affect thyroid hormone levels, blood sugar and blood pressure. That means anyone taking thyroid medication, diabetes medication, blood pressure medication, sedatives, immune-suppressing drugs or medications that affect the liver should get medical guidance first.
There have also been rare reports of liver injury linked to ashwagandha supplements. The LiverTox database notes that cases are uncommon, but they have been reported, which is something consumers should know.
Some people notice calmer sleep or less stress within a couple of weeks, while others notice nothing at all. Most studies that show benefits use ashwagandha for several weeks, often around 8 to 12 weeks, depending on the product and dose.
Side effects are usually mild, but they can happen. The most commonly reported ones include upset stomach, diarrhea, nausea, drowsiness and headache.
More is not automatically better here. Higher doses may increase the risk of side effects, and because supplements are not regulated the same way medications are, it is worth choosing products carefully.
The FDA explains that dietary supplements do not need premarket approval for safety and effectiveness before being sold. This is why I prefer products that are third-party tested by groups such as USP, NSF or ConsumerLab when possible.
Ashwagandha is sold as capsules, powders, gummies, teas and tinctures. Capsules are usually the easiest option because the dose is clear, and you do not have to pretend the earthy taste is delightful.
Many studies use doses somewhere around 300 to 600 milligrams per day of a standardized root extract, but dosing depends on the product. Always read the label, and do not combine multiple ashwagandha products unless your health care provider tells you to.
It is also a good idea to start low and pay attention to how you feel. Stop taking it and call a health care provider if you develop symptoms such as yellowing skin or eyes, dark urine, severe fatigue, persistent nausea, abdominal pain or unusual itching.
Ashwagandha deserves some of the attention it is getting, especially when it comes to stress and sleep. The research is not perfect, but there is enough there to say it may be helpful for some people.
That said, it is still a supplement, not a magic fix. It should not replace good sleep habits, balanced meals, physical activity, mental health support or medical care when you need it.
My take? Ashwagandha may be worth considering if you are a healthy adult looking for extra support with stress or sleep, but it should be used thoughtfully, purchased from a reputable brand and cleared with your doctor if you have any medical conditions or take medications.
And as always, no supplement gets to make up for a lifestyle that is running you into the ground. Annoying, I know, but still true.
