Stress has become such a normal part of everyday life that sometimes we barely notice it anymore.

Deadlines. Traffic. Notifications. Financial worries. Lack of sleep. Work responsibilities. Family responsibilities. And sometimes, simply having too many things on your mind at once.

While occasional stress is a normal response, experiencing it constantly can affect how you feel, sleep, think, and function throughout the day.

This is one reason ashwagandha has become increasingly popular in the wellness world. But beyond the social media posts and supplement trends, what exactly is ashwagandha—and what does medical research actually say about its benefits?

Let’s look at the science.

What Is Ashwagandha?

Ashwagandha (Withania somnifera) is an evergreen shrub traditionally used in Ayurvedic medicine, a traditional system of medicine that originated in India.

It has been used for thousands of years and is sometimes referred to as Indian ginseng or winter cherry, although it is not actually part of the ginseng family.

Ashwagandha contains several naturally occurring plant compounds, including a group known as withanolides, which researchers believe may contribute to some of the plant’s biological effects.

Traditionally, ashwagandha has been considered an adaptogen. The term is generally used for substances believed to help the body adapt to different forms of physical or psychological stress.

Today, ashwagandha is commonly included in supplements formulated for stress management, relaxation, sleep, and overall wellness.

According to the U.S. National Center for Complementary and Integrative Health (NCCIH), research suggests that certain ashwagandha preparations may be beneficial for stress and insomnia, although evidence for many of its other advertised uses remains limited.

What Are the Potential Benefits of Ashwagandha?

Ashwagandha has been studied for many possible uses, but some have considerably more research behind them than others.

1. Ashwagandha May Help Support Stress Management

This is currently one of the most researched reasons people use ashwagandha.

A 2024 systematic review and meta-analysis examined nine randomized controlled trials involving 558 participants. Researchers found that ashwagandha supplementation was associated with improvements in perceived stress and anxiety measures and reductions in serum cortisol compared with placebo.

However, researchers also emphasized that additional information is needed regarding long-term safety.

Another systematic review and meta-analysis involving 12 studies and 1,002 participants also found reductions in reported stress and anxiety compared with placebo. However, the researchers rated the certainty of evidence as low and called for more high-quality research.

So while the research is promising, ashwagandha shouldn’t be viewed as a cure for stress or anxiety.

2. Ashwagandha May Support Better Sleep

Stress and sleep often affect each other.

You become stressed, which makes it harder to sleep. Then lack of sleep can make the following day feel even more stressful.

Some small clinical studies suggest that ashwagandha extracts may modestly improve sleep.

According to the U.S. National Institutes of Health (NIH), participants in some studies reported falling asleep faster, sleeping longer, and waking less frequently during the night.

The NIH notes that sleep benefits observed in research were generally small and appeared more pronounced in some studies using at least 600 mg per day for eight weeks or longer.

This doesn’t mean ashwagandha works like a sleeping pill. Instead, researchers are studying whether its potential effects on stress and other biological pathways may indirectly support sleep.

3. Ashwagandha Contains Bioactive Plant Compounds

Ashwagandha contains several phytochemicals, including withanolides and alkaloids.

Withanolides are among the compounds scientists are investigating to understand the possible biological effects of ashwagandha.

However, it is important to understand that the amount and composition of these compounds can differ depending on whether a supplement uses the plant’s root, leaf, or a combination of both, as well as how the extract is produced.

That is one reason different ashwagandha studies cannot always be compared directly.

The Science of Stress: What Actually Happens Inside Your Body?

To understand why researchers are interested in ashwagandha for stress, it helps to first understand what happens when you’re stressed.

Stress isn’t simply an emotion.

It produces a biological response.

When your brain detects a potential threat or challenge, it activates several systems that prepare your body to respond.

One important system is called the hypothalamic-pituitary-adrenal axis, commonly shortened to the HPA axis.

Think of it as one of your body’s stress communication systems.

Your brain recognizes a stressor and sends signals that eventually tell your adrenal glands to release hormones, including cortisol.

Cortisol is often called the “stress hormone,” but cortisol itself isn’t bad. Your body needs it.

Cortisol helps regulate functions including your metabolism, immune response, blood pressure, and your body’s response to stress.

The problem is that modern stress isn’t always something you can physically escape from. Your deadline doesn’t disappear because your body activated its stress response. Your unread emails are still there.

Your bills still need to be paid.

And tomorrow’s responsibilities are still waiting.

When stress becomes persistent, the body’s stress-response systems can remain activated more frequently than they ideally should.

That is where researchers have become interested in ashwagandha.

How Could Ashwagandha Help With Stress?

Scientists are still investigating exactly how ashwagandha may influence the human stress response.

One area of interest is its potential relationship with the HPA axis and cortisol. Several clinical trials have measured cortisol levels alongside participants’ perceived stress.

For example, one randomized, double-blind, placebo-controlled study involved 64 adults experiencing chronic stress.

Participants in the treatment group received 300 mg of a specific high-concentration ashwagandha root extract twice daily, for a total of 600 mg per day, for 60 days.

Researchers reported improvements in stress-assessment scores compared with placebo.

Another randomized controlled trial studied adults experiencing chronic stress who received 300 mg of ashwagandha root extract twice daily for eight weeks. Researchers assessed perceived stress as well as serum cortisol and other measures.

More broadly, the NIH’s review of clinical research reports that several studies have found reductions in perceived stress and cortisol among people taking certain ashwagandha extracts.

That doesn’t mean ashwagandha simply “turns off cortisol.”

A more accurate way to understand the research is that certain ashwagandha preparations may influence aspects of the body’s stress response, which researchers have observed through measures such as perceived stress scores and cortisol levels.

More research is still needed to fully understand the mechanisms involved.

How Much Ashwagandha Has Been Studied for Stress?

This is where things become more complicated.

There isn’t currently one universally established dose of ashwagandha that everyone should take for stress.

According to the NIH Office of Dietary Supplements, clinical studies examining stress and anxiety have used very different preparations and amounts.

In one review discussed by the NIH, studies used approximately 240 to 1,250 mg per day of ashwagandha extract, while another study used whole-root granules equivalent to a much larger amount of root powder.

Several studies appeared to show greater benefits around 500–600 mg of extract per day than at lower amounts.

A separate systematic review and dose-response meta-analysis found favorable effects on stress in studies using approximately 300–600 mg per day.

However, milligrams alone don’t tell the entire story.

Different supplements may use different parts of the plant, extraction methods, concentrations, and levels of compounds such as withanolides.

So 300 mg of one ashwagandha preparation is not necessarily identical to 300 mg of another.

Research dosage should also not automatically be treated as a personal dosage recommendation. Always follow the serving directions of the specific product you’re using, and speak with a qualified healthcare professional if you’re unsure whether ashwagandha is appropriate for you.

Why Do People Take Ashwagandha Today?

For centuries, ashwagandha has been used within traditional Ayurvedic practices.

Today, the reason many people become interested in it is much more relatable: modern life can be stressful.

Think about a normal weekday.

You wake up and immediately check your phone.

You think about work while eating breakfast.

You spend the day jumping between tasks.

You finally get home, but your brain is still thinking about tomorrow.

Then you lie in bed physically tired while your mind is somehow still awake. Ashwagandha won’t remove those responsibilities.

It isn’t a “no more stress” pill.

Instead, research is investigating whether ashwagandha can be one supportive part of a broader stress-management routine.

That routine still matters.

Adequate sleep, regular movement, balanced nutrition, hydration, downtime, social connection, and addressing the actual sources of chronic stress are all important.

Supplements should complement healthy habits, not replace them.
