WHAT IS ASHWAGANDHA?
Also known as Indian ginseng and winter cherry, ashwagandha (Withania somnifera) is an evergreen shrub classified as belonging to the nightshade family. This botanical group, known officially as Solanaceae, includes familiar culinary plants such as potatoes, tomatoes, eggplants, and peppers. The plant produces small red fruits, blooming its green-yellow flowers in late summer before fruiting through November. But our interest in ashwagandha lies in its roots.
There has been a lot of buzz around ashwagandha in recent years, bordering on what can only be called spiritually coded, pseudoscientific balderdash, so let’s cut through some of the fluff immediately: ashwagandha is not a miracle plant. It’s not some mystic shortcut to elevated spiritual, much less pharmacological, states and it’s definitely not a substitute for proper rest.
At its core, ashwagandha belongs to a group of substances called adaptogens. Not in the vague, wellness-blog sense, but in a very specific physiological one, which we cover in detail in our dedicated article. Ashwagandha helps your body adapt to stress by regulating how your systems respond to it. Not by forcing stimulation or shutting down your nervous system, but by gently nudging your internal balance back toward baseline.

WHY ASHWAGANDHA EXISTS FOR YOU
Ashwagandha meets you at the exact point modern lifestyles tend to create. Not fully energetic, but not completely exhausted either, not in full fight-or-flight mode, but far from calm. Somewhere in between: alert, but frayed at the edges. The human body was never designed for constant activation. And yet, that’s exactly where our modern life of notifications, deadlines, caffeine, and pressure keeps it. In a steady hum that never quite switches off.
Enter ashwagandha. Known scientifically as Withania somnifera, its name carries a telling as to its role: “somnifera” comes from Latin, meaning “sleep-inducing”. But modern understanding would consider this a misnomer: ashwagandha doesn't sedate you but reduces nervous tension and brings the body back to a calmer baseline state.
Ashwagandha has been used for centuries in traditional systems like Ayurveda. But its historical and traditional origins are secondary at best: when too much mythology builds around an ingredient, especially one from the Indian subcontinent or the jungles of the Amazon, it becomes harder to communicate the science that actually matters. And what matters is this: ashwagandha works. Its effects are largely driven by compounds called withanolides, biologically active molecules that, in modern formulations, are standardized and measured to ensure consistency and potency far beyond raw plant use.
Ashwagandha exists for you because we’ve built a culture that runs on stimulation, one where coffee is routine, energy is expected, and only being constantly on, active, and productive is what gets rewarded. Nobody questions your fifth cup of coffee, but the moment something helps you slow down even slightly, it’s treated with suspicion and taboo. As if calm needed to be earned and as if quiet were a weakness.
Ashwagandha doesn’t dull or sedate you, it simply works under the radar to bring your system back toward equilibrium. And in a system that’s been pushed into overdrive for too long, equilibrium alone can feel like a completely different state of being
WHAT ASHWAGANDHA DOES
First we'll give a list of what ashwagandha does here in simple, understandable terms. In the following section, we'll describe in scientific terms the mechanisms behind each function.
Helps reduce stress and support a calmer mental state
As perhaps the most classic member on the list of adaptogens, ashwagandha is best known for its ability to help the body handle stress more effectively. It can reduce feelings of tension, nervousness, and being overwhelmed, allowing for a calmer, more stable mental state without dulling any alertness.
Improves sleep quality and recovery
Ashwagandha doesn't act as a sedative, in that it does not induce you to sleep. What it does is improve the quality of your sleep by reducing the underlying stress that interferes with rest. This leads to deeper, more restorative sleep and better overall recovery. For a more sleep-specific adaptogen, check out our reishi.
Supports healthy testosterone levels and physical performance
Ashwagandha has been shown to support testosterone levels, particularly in men experiencing chronic stress, one of the biggest factors affecting low testosterone production. By improving the body’s stress response, it creates conditions that support strength, endurance, and recovery.
Helps regulate energy levels throughout the day
Rather than providing a short-term boost, ashwagandha helps stabilize energy by reducing the physiological strain caused by stress. This results in more consistent energy levels without spikes and crashes.
Helps reduce stress-related cravings and supports metabolic balance
Chronic stress can disrupt appetite regulation and lead to increased cravings, particularly for high-sugar foods. Ashwagandha helps counter this by supporting a more balanced stress response, which can indirectly support healthier eating patterns.
Read the next section to find out how ashwagandha achieves all this.
HOW ASHWAGANDHA WORKS
Forewarned is forearmed: this section gets a little bit sciency. We'll try to keep the language readable, but the science itself will not be watered down.
The primary active compounds in ashwagandha are withanolides, a group of steroidal lactones [1] structurally similar to endogenous signaling molecules in the human body. What that means is that they have chemical structures that mimic those of compounds produced naturally. These compounds interact with multiple systems at once, particularly those involved in stress regulation, neurotransmission, inflammation, and hormonal balance.
Stress response and cortisol regulation (HPA axis)
Ashwagandha’s most well-documented effects center around the HPA axis, the hypothalamic-pituitary-adrenal system responsible for coordinating your stress response, which we described at length in our blog post on adaptogens.
We won't repeat all the science covered in the linked blog, but, in short, the HPA axis was designed for short bursts of activation. Problems arise when it never switches off. An improperly functioning HPA axis, usually the result of chronic stress, can lead to persistently elevated cortisol levels:
Impairs sleep
Suppresses testosterone production
Disrupts appetite regulation
Increases fat storage
Keeps the nervous system in a constant state of alertness
Ashwagandha appears to modulate this system by reducing excessive activation of the HPA axis. Rather than bluntly suppressing cortisol, it helps normalize cortisol levels, bringing them down when elevated and supporting stability over time. This is the foundation for many of its downstream effects, covered below:
Nervous system regulation and GABA signaling
Ashwagandha also interacts with the GABAergic system, one of the primary inhibitory pathways in the brain. What does that mean, you might ask? GABA (gamma-aminobutyric acid) is the neurotransmitter responsible for reducing neuronal excitability. That means it acts like a brake, slowing the brain down and preventing it from revving the gears in a constant state of high frequency.
Certain withanolides appear to:
Enhance GABA receptor signaling
Mimic GABA-like activity
Increase the brain’s sensitivity to inhibitory input
The result isn't sedation, but an increased capacity for calm. The nervous system becomes better at deescalation after activation, instead of staying “stuck on”.
Testosterone, endocrine function, and stress interplay
Ashwagandha’s effects on testosterone are closely tied to its impact on stress physiology.
Elevated cortisol and chronic stress can suppress the hypothalamic-pituitary-gonadal (HPG) axis, which regulates testosterone production. [2] This suppression affects signaling to the testes, particularly Leydig cells, which are responsible for synthesizing testosterone.
By reducing chronic stress signals and normalizing cortisol, ashwagandha helps remove inhibitory pressure on this system.
Some studies also suggest:
Improved luteinizing hormone (a hormone regulated by the hypothalamus responsible for signalling the production of testosterone) signaling
Enhanced testicular function under stress conditions, meaning the body can resist lowering testosterone levels even in the face of stress
The result is not artificial stimulation, but the return and restoration of the conditions required for healthy testosterone production.
Sleep and circadian regulation
Ashwagandha’s impact on sleep is not driven by sedation, but by its ability to reduce the physiological drivers of poor sleep. Elevated evening cortisol, persistent sympathetic activation, and excessive neural firing can all interfere with the transition into sleep. Think of it this way: if you can't fall asleep because of worries, voices in your head (we don't mean the crazy kind...), or 1000 thoughts sprinting nonstop, then ashwagandha doesn't make you drowsy, it just helps turn off all of that background noise.
It does so by:
Lowering stress signaling
Supporting GABAergic activity [3]
Stabilizing the nervous system
What this does is facilitate the shift from wakefulness to rest, often resulting in:
Improved sleep onset
Deeper sleep phases
Better perceived recovery
Energy metabolism and fatigue
Chronic stress is metabolically expensive.
Sustained cortisol elevation increases glucose output, alters insulin sensitivity, and places continuous demand on energy systems. Over time, this contributes to fatigue that is not solved by rest alone.
Ashwagandha helps reduce this metabolic strain by:
Lowering unnecessary stress signaling
Improving mitochondrial efficiency (as suggested in emerging research)
Stabilizing energy utilization
The result is more consistent energy, rather than short-lived stimulation. [4]
Cravings, appetite regulation, and metabolic balance
Stress has a direct influence on appetite regulation through hormones like cortisol, ghrelin, and insulin. Elevated cortisol can:
Increase cravings for high-calorie, high-sugar foods
Disrupt satiety signaling
Promote fat storage, particularly visceral fat
By modulating the stress response, ashwagandha indirectly supports:
More stable appetite regulation
Reduced stress-driven cravings
Improved metabolic balance over time [5]
This makes it particularly relevant in contexts where stress and eating behavior are closely linked.
Anti-inflammatory and neuroprotective effects
Ashwagandha also exhibits significant anti-inflammatory and antioxidant properties. [6]
Withanolides and other compounds appear to:
Inhibit NF-κB, a key regulator of inflammatory gene expression
Reduce pro-inflammatory cytokines such as TNF-α and IL-6
Support antioxidant defenses against reactive oxygen species
In the nervous system, this may translate to:
Reduced neuroinflammation
Protection of neuronal structures
Improved long-term brain health
While these effects are less immediately noticeable, they form part of the broader systemic support that ashwagandha provides.
Ashwagandha doesn't act on a single pathway; it works across multiple interconnected systems, gently adjusting how the body responds to stress, restores balance, and maintains internal stability. And that is precisely why its effects tend to feel less like a sudden change, and more like your system finally starting to work the way it was supposed to all along.
RESEARCH ON ASHWAGANDHA
Research on ashwagandha is both extensive and still evolving. Known for decades as a classical adaptogen, much of the current body of evidence focuses on the downstream effects of Withania somnifera on stress regulation. Many results are promising, but there is still plenty of research left to be done. Primary difficulties in research currently include:
Difficulty in determining upper toxicity levels
Consistently producing results across broad demographics
Potential cross interactions with concomitant medications
Use in food supplements where ashwagandha is just one of several botanicals
EFSA claims
The European Food Safety Authority has not yet issued its decision regarding the findings resulting from research on ashwagandha, many of which were submitted for evaluation all the way back in 2004. Many research findings regarding Withania somnifera thus remain on EFSA's list of on-hold claims. This means that sufficient evidence exists for these claims to be used in product descriptions and advertising without refuting them before the full process of approval is finished. Among these claims for ashwagandha are:
Ashwagandha has adaptogenic properties
Protects general health through antioxidant activity
Beneficially affects the heart and cardiovascular system
Provides supports in periods of mental and nervous tension, and of anxiousness
Helps support relaxation, mental, and physical wellbeing, and contributes to emotional balance and general wellbeing
International studies
Despite EFSA's slow approach to reviewing botanical claims, research from around the world has confirmed many of the effects that traditional cultures have found ashwagandha to possess. To give you a clearer picture of how ashwagandha works in real-world contexts, here are a few key studies for your reading pleasure, some of which are already linked in the footnotes of the previous section above:

HOW TO USE ASHWAGANDHA
Ashwagandha is not a one-time fix. Its effects build gradually, meaning consistency matters far more than timing or dose precision. We strongly recommend taking ashwagandha in the morning and during the day to regulate cortisol, and combining it with reishi in the evening for a stress-free transition to sleep.
Traditional usage
Ashwagandha was a staple botanical in rasayana, the one of Ayurveda’s eight branches of medicine focused on longevity and vitality. The root was traditionally ground into powder and mixed with warm milk or ghee. Modern understanding supports this practice, as ashwagandha contains both fat- and water-soluble compounds, meaning these combinations likely improved its absorption.
Modern usage
Ashwagandha’s rise in modern use mirrors the environment it addresses.
Chronic stress, constant availability, and sustained cognitive load keep the body’s stress-response system active far beyond what it was designed for. The HPA axis functions best when stress is intermittent and resolved. When activation becomes constant, elevated cortisol can begin to disrupt sleep, appetite, metabolism, and hormonal balance.
Ashwagandha is now widely used as part of daily routines aimed at restoring that balance, often in the form of standardized extracts, which provide consistent withanolide content and predictable effects.
If you're among the chronically stressed, or even if your stress levels are lower but you still want to explore the effects of ashwagandha, keep reading to see how best to take it:
Dosage and forms
Today, Withania somnifera can come in a myriad of shapes and sizes. You'll find capsules, tablets, raw powder, teas, gummies, and even as whole pieces of root. Most clinical research on ashwagandha has been conducted using standardized extracts such as KSM-66 or Sensoril, typically in the range of 300 to 600 mg per day, with defined levels of withanolides.
However, ashwagandha is also traditionally consumed as a whole-root powder, which contains a broader spectrum of compounds beyond just withanolides. While this makes precise standardization more difficult, it also reflects a more complete representation of the plant. Because of this, dosage with powder tends to be higher and less exact, and is best approached through consistent, regular use rather than strict milligram targeting. If taking powder, daily dosages of powder typically fall around 3,000–5,000 mg per day.
Start small and build up: begin with smaller dosage amounts and work your way up to full amounts as you see how your body reacts to it. Disclaimer: rare, ashwagandha has been associated with side effects such as liver issues, thyroid dysfunction, and gastrointestinal distress. It is not to be used during pregnancy or breastfeeding, or if you have hormone-sensitive prostate cancer.
When to take ashwagandha
Ashwagandha can be taken either in the morning or in the evening, depending on your goal.
Morning use is ideal for supporting stress resilience and stable energy throughout the day
Evening use may help if your primary focus is relaxation and sleep quality
In many cases, splitting the dose into two smaller servings, morning and evening, provides the most stable effect.
Our general recommendation is to prioritize morning and early afternoon use, followed by reishi in the evening for a more complete stress-management approach.
Other ingredients to combine it with
Ashwagandha works well both on its own and as part of a broader formulation.
It is often combined into nootropic stack with:
Other adaptogens for broader stress support
Minerals like magnesium for nervous system regulation
Compounds that support sleep, recovery, or metabolic balance
Its role in these combinations is rarely to dominate, but to stabilize the foundation so other ingredients can work more effectively.
Consistency over intensity
Taking more ashwagandha does not necessarily mean better results.
Its effects come from gradually influencing regulatory systems like the HPA axis and nervous system signaling. These systems respond best to steady, repeated input, not large, irregular doses.
Think of it less like a switch and more like the gradual recalibration of a system that has been out of balance for a long time.
What to mix it with
Raw ashwagandha has a strong, earthy, not particularly pleasant taste. Its name in Sanskrit loosely translates to “horse smell", which tells you basically everything you need to know. Capsules and tablets are the most convenient option. If using powder, we suggest masking the taste by mixing it into warm milk, oatmeal, or yogurt with fruit and honey, echoing its traditional use (nearly identical to how turmeric was consumed), while making it more palatable.
Powder
WHO NEEDS ASHWAGANDHA?
If you're reading this on your phone in the five minutes between one obligation and the next, ashwagandha could be for you. Consider it if:
You're just curious about adaptogens, and about an ingredient well-respected both in traditional cultures and in the modern laboratory
You feel jittery and mentally “on edge” even when you're physically exhausted
Sleep doesn’t restore you and you wake up feeling just as tired as you were when you went to bed
Stress has begun to affect the way your body looks and operates (e.g. increased weight, erratic menstrual cycle, non-existent libido)
You rely on caffeine, and not just in the way that all of the western world does, but if literally you're using caffeine just to function at baseline
You're a woman over 35 looking for any and every way to ease the transition from perimenopause into menopause
Ashwagandha is for anyone who would like another, natural arrow in their quiver for combatting the stressful effects of modern life.
HOW AND WHY JUNAI USES ASHWAGANDHA
Junai uses the whole root powder of ashwagandha grown organically in India. It is sold in 250 g pouches, giving you roughly 50 daily servings. We are aware of the benefits of using standardized extracts, but also believe in the benefits of whole, raw food. Besides, extracts usually only focus on specific compounds, namely with withanolides, ignoring many of the other useful compounds in ashwagandha, all of which add their own share to ashwagandha's cumulative effects. Offering raw powder also allows us to avoid investing in extraction or complicated formulation, which lets us keep the product as accessible as possible for you.
We are thrilled to offer ashwagandha, as it finds a support role to complement all 3 of our hero products:
Junai HIM → resilience, support for testosterone, support for recovery
Junai HER → nervous system support, emotional balance, hormonal harmony
Junai SLIM → mitigated stress-related craving and metabolic disruption
It's rare that an ingredient is so versatile that it can lend support to 3 radically different formulations. When we find one that does, we get excited and simply have to offer it.
WHAT TO EXPECT WITH ASHWAGANDHA
As with most adaptogens, effects are not immediate. Ahwagandha is not a stimulant, nor, as we've written above, is it a miracle ingredient. It is a wonderful ingredient, to be sure, but its effects appear gradually and cumulatively. Most people begin to notice subtle changes within:
1–2 weeks → reduced sense of stress and tension
3–4 weeks → improved sleep quality and emotional stability
Longer-term use → more consistent energy, resilience, and recovery
The key is in regular use, as mere sporadic intake will not produce the effects you're interested in.
QUICK RECAP OF ASHWAGANDHA
More than just a root used in Ayurvedic medicine, ashwagandha or Withania somnifera is:
One of the most classical adaptogens, full of withanolides, which help your body regulate its response to stress
Full of bioactive compounds with a range of effects from antioxidant and anti-inflammatory agents to anti-stress pathways and potential anti-tumor and anti-cancer mechanisms
A key ally in the modern world, which is designed to keep your stress response system in constant overload
Available in many formats, including standardized extracts and Junai's raw powder
Both water and fat-soluble, so should be mixed with healthy fats for best absorption
Effective in consistency, not immediate effect. That means it's not important what time of day you take it, though we suggest using it during the day and combining it with reishi for the evening
Not a mystical miracle plant, despite being from India. It's a slow, gradual burn, taking weeks to build up a cumulative effect.
To be taken in small quantities at first and gradually increased as the body adapts and responds
UNDER NO CIRCUMSTANCES to be taken when pregnant, breastfeeding, have hormone-sensitive prostate cancer, or in combination with other medications known for liver toxicity.
