What the research says about KSM-66 Ashwagandha and L-Theanine
Educational summaries of published research on ashwagandha (Withania somnifera) and L-theanine; not product-specific claims. CanPrev Adrenal Chill for Men's own claims are the uses authorized under NPN 80089995: helps increase resistance to stress, athletic/workout support, and helps promote healthy testosterone production in males.
300 mg twice daily cut stress scores and cortisol in 60 days
In a randomized, double-blind, placebo-controlled trial of 64 adults with chronic stress taking 300 mg of a high-concentration full-spectrum ashwagandha root extract twice daily, stress-assessment scores and serum cortisol were both significantly reduced versus placebo after 60 days, with only mild, comparable adverse effects in both groups.
Human RCTSame 300mg-twice-daily dose reduced stress, cortisol and food cravings
A double-blind, placebo-controlled trial of 52 adults under chronic stress taking 300 mg ashwagandha root extract twice daily found significant improvements in Perceived Stress Scale scores, food cravings, happiness and serum cortisol compared to placebo over 8 weeks.
Human RCTMeta-analysis finds a dose-response effect between 300-600 mg/day
Pooling 12 randomized trials (1,002 participants), a systematic review found ashwagandha supplementation significantly reduced both anxiety and stress scores versus placebo, with a non-linear dose-response analysis showing the most favorable effect on stress at doses of 300-600 mg/day - the range this product's twice-daily dosing falls within.
Meta-analysisSystematic review: all 5 human trials favored ashwagandha over placebo
A systematic review of five human randomized controlled trials using various ashwagandha dosages found every study reported greater improvement in anxiety or stress scale scores with ashwagandha than with placebo, though the authors flagged unclear-to-high risk of bias across the heterogeneous studies.
Systematic reviewInternational clinician taskforce: 'modestly supported' for anxiety
A joint WFSBP/CANMAT taskforce of 31 international psychiatry researchers graded ashwagandha as 'modestly supported' (Grade A evidence) for anxiety disorders in its evidence-based guidelines for nutraceuticals and phytoceuticals in psychiatric care.
Clinical guideline reviewNewer formulation improved anxiety and sleep scores without a cortisol change
A 2025 randomized, double-blind, placebo-controlled trial of 90 adults with mild-to-moderate stress found a low-dose (125 mg) ashwagandha formulation significantly improved Perceived Stress Scale, Beck Anxiety Inventory and Pittsburgh Sleep Quality Index scores versus placebo - though serum cortisol and salivary alpha-amylase did not differ significantly between groups, an honest reminder that not every outcome moves together.
Human RCTSix weeks improved self-reported sleep quality by 72%
In 150 adults with non-restorative sleep, a standardized ashwagandha extract taken once daily for 6 weeks produced a 72% improvement in self-reported sleep quality versus 29% for placebo, plus actigraphy-measured gains in sleep efficiency, total sleep time and sleep latency.
Human RCTRoot extract improved sleep in both healthy adults and insomnia patients
An 8-week, placebo-controlled trial in 80 participants found ashwagandha root extract significantly improved sleep-onset latency, sleep efficiency and anxiety scores, with larger gains in those with diagnosed insomnia than in healthy sleepers.
Human RCTMeta-analysis: a small but real effect, strongest at 600 mg/day or more
Pooling five RCTs (400 participants), a systematic review found a small but significant benefit of ashwagandha extract on overall sleep, most pronounced in adults with diagnosed insomnia, at treatment doses of 600 mg/day or more for 8 weeks or longer - matching this product's full twice-daily dose.
Meta-analysisA single 200 mg dose raised relaxation-linked brain activity and cut cortisol
In a randomized, triple-blind, placebo-controlled crossover study, a single 200 mg dose of L-theanine significantly increased frontal-region alpha brain-wave power and produced a greater decrease in salivary cortisol than placebo following an acute stress challenge - signals consistent with a calming effect.
Human RCTL-theanine drink reduced subjective stress and cortisol response to a stressor
In a randomized, double-blind, placebo-controlled crossover trial of 34 healthy adults, an L-theanine-based drink significantly reduced subjective stress response one hour after a cognitive stress task, with reduced salivary cortisol three hours post-dose versus placebo.
Human RCTA balanced review: promising signals, but more rigorous trials still needed
A 2025 review of L-theanine's chemistry and clinical evidence found it may increase relaxation-linked alpha brain waves, reduce stress and anxiety, and improve sleep quality in some studies, but concluded findings are often inconsistent and called for more rigorous human clinical trials before overstating the evidence.
Review300 mg twice daily improved memory and executive function in 8 weeks
A randomized, double-blind, placebo-controlled study of 50 adults with mild cognitive concerns taking 300 mg ashwagandha root extract twice daily found significant improvements in immediate and general memory (Wechsler Memory Scale subtests) plus executive function, sustained attention and information-processing speed versus placebo.
Human RCT600 mg/day improved episodic memory, working memory and attention accuracy
An 8-week, placebo-controlled trial of 120 adults with self-reported cognitive and energy problems, taking 600 mg/day of ashwagandha root extract, found significant improvements in computerized measures of episodic memory, working memory, attention accuracy, mood and executive function versus placebo, with no serious adverse events.
Human RCTL-theanine combined with caffeine sharpened attention-switching speed
In a randomized, placebo-controlled crossover study, 100 mg L-theanine combined with 50 mg caffeine improved both the speed and accuracy of an attention-switching task versus placebo - this trial studied L-theanine alongside caffeine rather than alone, so the isolated contribution of L-theanine cannot be fully separated from the caffeine's effect.
Human RCTSame 300mg-twice-daily dose increased strength and testosterone in young men
In an 8-week randomized, double-blind, placebo-controlled trial of 57 young men undergoing resistance training, 300 mg of ashwagandha root extract twice daily produced significantly greater gains in muscle strength (bench press, leg extension), muscle size, and serum testosterone (+96.2 ng/dL vs +18.0 ng/dL for placebo) compared to placebo.
Human RCTSame 300mg-twice-daily dose improved semen parameters and sexual health in healthy men
An 8-week randomized, double-blind, placebo-controlled trial of 100 healthy men aged 30-50 taking 300 mg ashwagandha root extract twice daily found significant improvements in semen volume, sperm concentration and morphology, sexual desire, and orgasm/desire domains of the International Index of Erectile Function, with no adverse events and no change in liver or kidney markers.
Human RCTFree testosterone and luteinizing hormone rose significantly in men
In a 12-week randomized, double-blind, placebo-controlled trial of overweight adults with self-reported stress and fatigue, men taking 200 mg ashwagandha root extract twice daily showed a significant increase in free testosterone and luteinizing hormone versus placebo, alongside reduced fatigue scores, even though the primary stress-scale outcome did not differ significantly from placebo.
Human RCTSame 300mg-twice-daily dose showed no thyroid, liver or kidney abnormalities
An 8-week randomized, placebo-controlled safety study in 80 healthy adults (40 men, 40 women) found no clinically significant changes in hematology, liver enzymes, kidney markers or thyroid hormone profile with ashwagandha root extract taken at 300 mg twice daily; no adverse events were reported.
Human RCT12-month observational study: testosterone rose, cortisol fell, no liver signal
In a 12-month, multi-center observational safety study of 191 adults, long-term ashwagandha root extract use was associated with only 18 mild, self-resolving adverse events, no clinically significant change in liver enzymes, a significant decrease in serum cortisol, and a significant increase in serum testosterone.
Long-term safety studyA real published case underscores caution in pre-existing liver disease
A 2025 case report described a patient with a pre-existing chronic liver condition who developed acute-on-chronic liver failure after taking ashwagandha, illustrating why people with existing liver disease should be especially cautious with any herbal supplement and discuss use with a health care practitioner first.
Case reportA 3,000-year-old Rasayana examined through a modern lens
A comprehensive ethnopharmacology review traces ashwagandha's documented use across classical Ayurvedic texts (Charaka Samhita, Susruta Samhita) as Balya (strength-promoting), Brusya (sexual performance enhancer) and Rasayana, cross-referenced against its modern phytochemical and clinical-trial evidence base.
ReviewA comprehensive look at ethnopharmacology, phytochemistry and toxicology
A wide-ranging review of Withania somnifera's traditional use, phytochemistry and pharmacological activities found potent bioactivity across anti-inflammatory, neuroprotective and adaptogenic domains, while also surveying toxicological considerations for safe use.
ReviewWithanolides: the steroidal lactones behind ashwagandha's activity
A phytochemistry review catalogues withanolides - a class of steroidal lactones unique to Withania somnifera - as the primary bioactive compounds responsible for the plant's pharmacological effects, providing the chemical basis for standardizing extracts like KSM-66 to a specific withanolide percentage.
