So it’s Men‘s Health Month again.
Which usually means a flood of articles telling you to sleep more, stress less, and maybe eat a vegetable. Good advice. But not exactly practical when you’re juggling work, kids, training, and whatever else is on your plate.
Here‘s something that actually fits into a busy life: Ashwagandha, Here's what you actually need to know about Ashwagandha: it’s one of the few supplements where the science has caught up to the hype.
Over the past two years, multiple clinical trials have shown real, measurable effects for men. On stress hormones. On testosterone. On sleep. On focus.
Below are six of them, pulled straight from 2025–2026 studies. No fluff. No “ancient secret” marketing language. Just the data.
Benefit 1: Reduces Stress and Lowers Cortisol Naturally
Chronic stress is pervasive. For men, unmanaged stress contributes not only to mental fatigue but also to sleep disruption, hormonal imbalances, and reduced quality of life. Ashwagandha’s primary claim to fame is its ability to help the body adapt to stressors—a property known as adaptogenicity.
A 2025 systematic review and meta‑analysis published in BJPsych Open examined 15 randomized controlled trials involving 873 participants and found that Ashwagandha supplementation significantly reduced anxiety (measured by the Hamilton Anxiety Rating Scale, HAM‑A) and stress (measured by the Perceived Stress Scale, PSS), with statistically significant reductions in cortisol levels at eight weeks of treatment. Similarly, a 2025 review in Nutrition and Health confirmed a significant reduction in cortisol levels across multiple trials, supporting Ashwagandha’s role in lowering this key biological stress marker.
Mechanistically, research suggests Ashwagandha modulates hypothalamic‑pituitary‑adrenal (HPA) axis activity, which governs the body’s stress response. The bottom line: Ashwagandha isn’t a sedative—it helps your nervous system handle stress more effectively, without the grogginess often associated with conventional approaches.
➡️ When supporting your body through periods of high stress, a holistic approach matters. Maintaining gut health is also closely tied to mood regulation—the gut‑brain axis plays an important role in how we experience stress. GreenPeople’s 4-in-1 Gut Health & Mood Support combines slippery elm, digestive enzymes, and probiotics to support digestive comfort alongside mental well‑being. For a convenient, daily stress‑support option, the GreenPeople Natural Stress Relief & Adrenal Support Gummies are formulated to help the body adapt to everyday stressors.
Benefit 2: Supports Healthy Testosterone Levels and Hormonal Balance
Testosterone is central to men’s health—influencing energy, muscle mass, libido, and mood. Multiple clinical studies have now shown that Ashwagandha supplementation can produce small but significant increases in serum testosterone levels.
A 2025 systematic review in Phytotherapy Research evaluating Ashwagandha’s hormonal effects concluded that evidence indicates Ashwagandha may increase testosterone levels in men. In a 2024 randomized, double‑blind, placebo‑controlled trial involving healthy subjects with high stress levels, participants receiving Ashwagandha extract (containing 35% withanolide glycosides) at 60 mg or 120 mg daily for 60 days experienced significant increases in total testosterone—22% in the lower‑dose group and 33% in the higher‑dose group—compared to a mere 4% increase in the placebo group (p < 0.0001).
Another 2025 randomized controlled trial examining Ashwagandha’s effects on energy and endurance in 40 healthy men found that 42 days of supplementation with 300 mg twice daily led to increased serum testosterone levels alongside significant improvements in physical performance and reduced cortisol. A separate 2025 six‑month randomized clinical trial in healthy older men further confirmed that standardized Ashwagandha root extract is safe and well tolerated, with improvements noted in testosterone levels, inflammation markers, and immune indicators.
These findings suggest Ashwagandha may offer meaningful hormonal support—particularly in men experiencing stress‑related declines in testosterone.
Benefit 3: Enhances Physical Performance, Strength, and Recovery
For active men—whether athletes, weekend warriors, or anyone looking to maintain functional fitness—Ashwagandha’s impact on exercise performance and recovery is noteworthy.
The same 2025 trial mentioned above evaluated Ashwagandha’s effects on energy and endurance in 40 healthy men. After 42 days of supplementation (300 mg twice daily), the Ashwagandha group showed significant improvements in the 6‑minute walk test, stair climbing test, chair standing test, and one‑leg stance test compared to placebo (p < 0.001). Participants also reported improved quality of life scores on the SF‑36 survey.
Earlier research similarly supports Ashwagandha’s role in sports medicine—specifically its ability to enhance muscle strength, power, and recovery when combined with resistance training. The mechanism appears to involve both cortisol reduction (which can otherwise impair recovery) and direct anabolic‑supportive effects.
Benefit 4: Improves Cognitive Function, Memory, and Focus
Mental clarity and cognitive performance are just as important as physical health—especially for men navigating demanding careers and family responsibilities. Ashwagandha’s potential as a nootropic is increasingly supported by clinical evidence.
A 2024 randomized, double‑blind, placebo‑controlled study investigated the effects of liposomal Ashwagandha supplementation (225 mg/day for 30 days) on cognitive function in 59 healthy young adults. Results showed significant improvements in word recall, picture recognition, digit vigilance, and reaction time on the Stroop test, along with reductions in tension and fatigue. The researchers concluded that Ashwagandha supplementation improved multiple measures of memory, attention, vigilance, and executive function.
A 2025 Frontiers in Reproductive Health study also reported that Ashwagandha supplementation significantly improved several aspects of cognitive function—including global cognition, memory, attention and processing speed, executive function, and visuospatial ability—in adults.
The bottom line: Ashwagandha may help sharpen mental performance and combat brain fog, particularly in the context of stress‑related cognitive decline.
Benefit 5: Promotes Sexual Health and Reproductive Function
Sexual health is a sensitive yet critically important aspect of men’s overall well‑being. Recent clinical research suggests Ashwagandha can meaningfully improve sexual function and fertility parameters.
A 2025 prospective, randomized, double‑blind, placebo‑controlled study evaluated Ashwagandha root extract (ARE) in 100 healthy men aged 30–50 years. Participants received 300 mg of ARE twice daily or placebo for eight weeks. Results showed significant improvements in semen volume (p = 0.005), sperm count (p = 0.006), sperm concentration (p = 0.007), and sperm morphology (p = 0.007). The ARE group also demonstrated better scores on the Sexual Desire Inventory‑2 (p < 0.05) and the orgasm and sexual desire domains of the International Index of Erectile Function (p < 0.05), along with improved quality of life measures (p < 0.0001). No adverse events were reported.
A 2026 follow‑up study published in Frontiers in Reproductive Health confirmed these findings in 76 healthy men aged 30–50, showing that eight weeks of ARE supplementation led to a 36% increase in ejaculate volume, a 38% improvement in total sperm count, and an 87% increase in total sperm motility—outcomes with moderate to large effect sizes indicating clinically meaningful benefits.
These results position Ashwagandha as a well‑tolerated, natural intervention for men seeking to support reproductive and sexual health.
Benefit 6: Improves Sleep Quality
Sleep is foundational to every aspect of health—recovery, hormonal regulation, cognitive performance, and mood. Ashwagandha’s calming properties extend to sleep support.
A 2026 prospective, randomized, double‑blind, placebo‑controlled trial directly compared Ashwagandha root extract (ARE) with melatonin for improving sleep quality in 200 adults. Participants were randomized to receive ARE (300 mg twice daily), melatonin (3 mg/day), a combination of both, or placebo for eight weeks. Sleep onset latency (SOL) was significantly reduced across all treatment groups, with the combination therapy producing the most pronounced benefits (p < 0.0001). The combination group also showed significant improvements in total sleep time, wake after sleep onset, and sleep efficiency (p < 0.0001).
The researchers concluded that both Ashwagandha and melatonin improve sleep disturbances in adults, with combination therapy producing the most consistent benefits. Importantly, Ashwagandha’s sleep‑promoting effects appear linked to its stress‑reducing and mild anxiolytic properties rather than direct sedation—offering a natural, non‑habit‑forming alternative for those who struggle with racing thoughts at bedtime.
Putting It All Together: A Practical Guide to Ashwagandha
With so many benefits, it’s natural to wonder how best to incorporate Ashwagandha into your routine. Here’s what the research suggests.
Safety Profile: Across multiple clinical trials, Ashwagandha has been shown to be safe and well tolerated. The 2025 six‑month randomized trial in healthy older men found no adverse effects. However, rare case reports have associated Ashwagandha with reversible liver injury, typically appearing after 2–12 weeks of use, though most cases resolve within 1–4 months of discontinuation. Individuals with pre‑existing liver conditions should consult a healthcare provider before use.
Who Should Avoid: Pregnant or nursing women, individuals with hyperthyroidism, and those taking sedatives or thyroid medications should consult a healthcare professional before using Ashwagandha.
Quality Matters: Like all supplements, quality varies significantly by brand. Choose products from reputable manufacturers that use third‑party testing to verify potency and purity.
Frequently Asked Questions
Q: How long does it take for Ashwagandha to work for stress and anxiety?
A: Most clinical studies show benefits appearing after 4–8 weeks of consistent daily use. The 2025 meta‑analysis in BJPsych Open found statistically significant reductions in anxiety and cortisol levels at eight weeks. Some people report subtle improvements in stress resilience as early as two weeks, but full effects typically require longer supplementation.
Q: Can Ashwagandha lower cortisol too much?
A: Ashwagandha is classified as an adaptogen, meaning it helps normalize cortisol levels rather than simply suppressing them. In individuals with chronically elevated cortisol, supplementation typically brings levels down toward the normal range. No clinical trials have reported clinically problematic cortisol suppression at standard doses (300–600 mg/day).
Q: Is Ashwagandha safe to take every day long‑term?
A: Most clinical trials have studied Ashwagandha for 8–12 weeks, with one 2025 six‑month trial confirming its safety and tolerability in healthy older men. Many people take Ashwagandha cyclically (e.g., 3 months on, 1 week off). If you plan to use it long‑term, consulting a healthcare provider is advisable.
Q: Can Ashwagandha affect thyroid function?
A: Yes, Ashwagandha may increase thyroid hormone levels and should be used with caution by individuals with hyperthyroidism or those taking thyroid medications. If you have a thyroid condition, consult your healthcare provider before starting Ashwagandha.
Q: What’s the best time of day to take Ashwagandha?
A: Many people prefer taking Ashwagandha with meals to minimize any potential gastrointestinal discomfort. Some split the dose—morning for daytime stress and focus support, evening for relaxation and better sleep. The 300 mg twice‑daily regimen used in many clinical trials is a practical starting point.
Closing Thoughts
Ashwagandha stands out as one of the most comprehensively researched adaptogenic herbs available today. From stress and hormonal balance to physical performance, cognitive function, sexual health, and sleep—its benefits span multiple dimensions of men’s health, all supported by an accumulating body of high‑quality clinical evidence.
As with any supplement, Ashwagandha is not a magic bullet. It works best as part of a broader wellness foundation—balanced nutrition, regular physical activity, adequate sleep, and effective stress management. But for men looking to support their body’s natural resilience, energy, and vitality, Ashwagandha deserves serious consideration.
