Pantry Symposium] Stress and anxiety can gridlock nearly every aspect of daily life, from sleep and focus to energy and mood. As a result, many people seek natural approaches to promoting calmness and emotional balance. Among the most buzzed-about herbal benefits is ashwagandha, a traditional Ayurvedic herb that’s been studied to support stress, anxiety and sleep. Research suggests it might help alleviate perceived stress, ease symptoms of anxiety, and lower cortisol levels while improving the quality of sleep, although evidence for all these potential benefits is still emerging and its long-term safety remains unclear.
Ashwagandha is frequently referred to as an adaptogen, which means it can help the body better respond to stress. Most commercial supplements employ root extract, and studies have investigated various extract types, doses and treatment durations. Multiple clinical trials suggest good benefits, particularly for stress and sleep, but the results come from various products tested in various study designs.
What Is Ashwagandha?
Withania somnifera, more commonly known as Ashwagandha is a shrub that has been used in traditional Ayurvedic medicine for thousands of years. Because it’s thought to enable the body to resist and adapt to physical and mental stress, it’s commonly referred to as an adaptogen. The root is the most commonly used part of the plant and it contains active compounds called withanolides, alkaloids, etc. [1]
The name “ashwagandha” is frequently described as being rooted in the root’s unique smell, and the herb also is sometimes referred to as Indian ginseng or winter cherry (though it is not related to true ginseng). Today’s supplements might utilize root-only extracts, root-and-leaf extracts, or powdered root. [1]
Traditionally, ashwagandha has been taken for:
- stress reduction
- anxiety support
- sleep improvement
- energy balance
- mood support
- general wellness
How Ashwagandha May Help Cut Down on Stress
Stress triggers the body’s stress response system, which includes cortisol, the primary stress hormone. When cortisol remains too high for an extended period of time, it can lead to fatigue, insomnia, irritability and mental fatigue. Ashwagandha may support a healthier stress response by affecting HPA, or hypothalamus-pituitary-adrenal, axis as well as decreasing cortisol in some research.
In a randomized placebo-controlled trial, adults with chronic stress showed significant reductions in stress scores and lower cortisol after taking ashwagandha extract compared to placebo. Other systematic reviews of clinical trials have also shown that ashwagandha may lower perceived stress and stress-induced fatigue. [3]
Ashwagandha may help stress by:
- supporting a balanced cortisol response
- improving resilience to daily stress
- reducing mental fatigue
- encouraging relaxation without functioning like a powerful sleeping pill
Ashwagandha for Anxiety Relief
it is common for anxiety relief as well. Clinical studies and systematic reviews indicate it might help alleviate anxiety symptoms, particularly if stress and poor sleep are at play as well. A 2022 meta-analysis of studies on ashwagandha found that the herb significantly reduced anxiety compared with placebo, but the authors cautioned that the certainty of evidence was low because such small and varied in their design. [4]
It is also thought to effect change in pathways that keep stress in check and possibly promote a balanced neurotransmitter environment all of which may help the mind become calmer. Some trials note reductions in nervousness, restlessness and emotional tension.
Potential anxiety-related benefits include:
- reduced nervousness
- better calmness
- improved emotional balance
- less racing thought activity
- greater stress tolerance
Ashwagandha and Cortisol: Why it Matters
Cortisol is crucial for normal body function, but chronically high levels can impact energy, sleep and mood. Ashwagandha has been researched for its potential impact on lowering cortisol. In people trials, study subjects who took ashwagandha had lower cortisol levels compared to placebo, which could help explain why stress seems more manageable for some users. [2]
When cortisol is better balanced people may feel:
- steadier mood
- better sleep quality
- less physical tension
- improved focus
- lower stress sensitivity
Ashwagandha for Sleep and Relaxation
Stress and anxiety can disrupt sleep, and poor sleep can in turn exacerbate stress. Ashwagandha could help disrupt that cycle. Clinical trials indicate it can contribute to an increase in overall sleep quality, sleep onset and feelings of restfulness particularly in those with insomnia or sleep disturbance. [5]
In a randomized study in healthy adults, the use of standardized ashwagandha extract was shown to improve sleep quality at six weeks. In another trial, researchers said an extract derived from the root of ashwagandha improved sleep quality and helped alleviate insomnia, noting that participants tolerated the supplement well.
Ashwagandha may support sleep by:
- calming stress-related overactivity
- reducing nighttime restlessness
- improving sleep quality over time
- facilitating a less rushed bedtime routine
Benefits of Ashwagandha
While stress and anxiety relief are the primary reasons people take ashwagandha, research has also investigated a few other potential benefits.
Mood Support
Certain studies indicate that ashwagandha can help regulate overall well-being and mood balance, particularly when stress is involved. [3]
Cognitive Support
A randomized trial suggests improvements in memory, focus, psychological well-being and sleep quality among stressed adults who took a standardized extract. [7]
Energy Balance
Ashwagandha is not a stimulant, but by working to help the body adapt to stressors, it may cut down on that tired, worn-out feeling many of us get when we are under chronic stress.
Physical Wellness
Ashwagandha has also been researched for its effects on general vitality and recovery, although these outcomes fall outside the primary research focus of stress and anxiety support. [1]
Who May Consider Ashwagandha?
Ashwagandha may be worth trying for adults who have:
- chronic stress
- mild anxiety
- poor sleep linked to stress
- burnout
- mental fatigue
- difficulty relaxing
- overthinking or restlessness
Despite the promising research, ashwagandha remains a supplement not a substitute for medical attention. A health care professional should be consulted if symptoms are severe, persistent or interfere with normal functioning.
Recommended Ashwagandha Dosage
Because studies have used different extracts and strengths, there’s no single universal dose. But the NIH Office of Dietary Supplements says that multiple studies used doses between 240 mg/day and 1,250 mg/day of extract, and several perks seemed more prominent at rates higher than 500 to 600 mg/day. An international task force provisionally recommended 300 to 600 mg/d of a standardized root extract for generalized anxiety disorder, though with the caveat that further research is needed. [1]
- Common dosage ranges include:
- 300 mg to 600 mg per day of standardized root extract
- once or twice daily
- with food if stomach is sensitive
Some popular supplement styles include:
- root extract capsules
- root-and-leaf extract capsules
- powdered root
- liquid extracts
How Long Does It Take for Ashwagandha to Work?
Ashwagandha generally has a gradual, rather than instant effect. Beneficial effects were not unusual after a few weeks of use, for example at around 6 to 8 weeks in studies. Some might start to feel a slight level of calmness before long, but it generally requires consistent use to realize the full effects. [6]
This might be the basic timeline:
- Week 1: gentle unwinding or better routine alignment
- 2 to 4 weeks: less muscle tension or improved sleep
- Week 6 to 8: more pronounced stress and anxiety assistance [6]
Best Time to Take Ashwagandha
It depends on the goal, the best time.
Morning use might be right for people who want:
- calm focus
- stress resilience through the day
Evening use may be appropriate for individuals who:
- relaxation
- sleep support
Others divide the dose into morning and evening. The best timing varies by product and personal response, since studies have used different schedules.
Ashwagandha Supplement Forms
Ashwagandha is available in multiple formats, each with its benefits and drawbacks.
Capsules
These are the most convenient and simplest for accurate dosing.
Powder
It can be added to drinks or smoothies, but the flavor is intense.
Gummies
They are simpler to ingest, but they can include added sugary items and lower active quantities.
Liquid Extracts
These are typically easy to work with, though the dosing can vary depending on the brand.
Of these capsules are the most common study form. [1]
Possible Side Effects of Ashwagandha
Most studies suggest that ashwagandha is well tolerated after short-term use, but side effects may occur. The most frequent are upset stomach, loose stools, nausea and drowsiness. Very rarely, there have been reports linking ashwagandha supplements to liver injury.
Possible side effects may include:
- stomach upset
- diarrhea
- nausea
- drowsiness
- vomiting in some cases
Who Should Avoid Ashwagandha?
Ashwagandha may not be suitable for everyone. The NCCIH recommends against it during pregnancy and breastfeeding, and cautions that the long-term safety is unproven. The NIH fact sheet also mentions potential effects on the thyroid, liver concerns and risk of interaction with certain medications.
Phyto-therapeutics might not be right for those who:
- are pregnant or breastfeeding
- have thyroid disorders
- take sedatives or anti-anxiety medicines
- have liver concerns
- have hormone-sensitive conditions
How to Select a Quality Ashwagandha Supplement
Not every product is made the same, and quality matters. Seek supplements that specifically note extract type and withanolide content, as well brands that utilize third-party testing where possible. But because studies have applied different preparations, a transparent label is critically necessary. [1]
A good supplement usually has:
- standardized extract
- clear dosage per serving
- withanolide percentage listed
- third-party testing
- minimal unnecessary fillers
Ashwagandha vs Other Stress Supplements
Ashwagandha is commonly compared to magnesium, L-theanine and rhodiola.
- Magnesium (may boost relaxation and help muscle function) vs ashwagandha (more studied for balancing stress hormones).
- Ashwagandha vs L-theanine: L-theanine can feel faster acting, while ashwagandha tends to be taken over time.
- Ashwagandha vs rhodiola: rhodiola is commonly associated with energy and fatigue support, while ashwagandha is typically selected for calm and stress relief. 1
How to Naturally Extend the Benefits of Ashwagandha
Ashwagandha is most effective when integrated into a wider routine. If you adopt healthy habits, the benefits can feel more profound.
Helpful habits include:
- regular sleep timing
- breathing exercises
- meditation
- balanced meals
- less excess caffeine
- daily movement
- screen breaks before bed 1
