6 Documented Benefits
4/5 Evidence Score

Sensoril® is a standardized ashwagandha extract (Withania somnifera) originally developed by Natreon (now part of Verdure Sciences) — distinguished by use of both root and leaf (vs root-only) and standardization to ≥10% withanolide glycosides + ≥32% oligosaccharides + ≤0.5% withaferin A. Multiple RCTs in stress, sleep, cognitive performance, and exercise applications. Among the most-studied ashwagandha branded forms alongside KSM-66 and Shoden. Used for: stress reduction, sleep quality, cognitive function, exercise tolerance, mood support.

Studied Dose 125-500 mg/day Sensoril (research-validated; stress applications often 250 mg/day)
Active Compound Withania somnifera root + leaf — ≥10% withanolide glycosides + ≥32% oligosaccharides + ≤0.5% withaferin A

Benefits

Stress Reduction

RCT (n=130) showed Sensoril reduced perceived stress, modulated cortisol, and improved C-reactive protein vs placebo. Foundation Sensoril stress evidence.

Supported by Trial 1

Sleep Quality Improvement

Some ashwagandha trials report improvements in sleep quality and sleep latency, generally attributed to its adaptogenic stress-reducing effect (no dedicated Sensoril sleep RCT appears in this page's references).

Supported by Trial 2

Cognitive Performance

A single small adjunctive trial in adults with bipolar disorder (Chengappa 2013, n=53) reported improvements in working memory and reaction time; this is preliminary evidence in a clinical population, not established cognitive enhancement in healthy adults. Reported for context as mood/cognitive support, not a treatment.

Supported by Trial 1, Trial 2

Cortisol Modulation

Documented effects on cortisol response — modulates excessive cortisol from chronic stress without complete suppression.

Supported by Trial 1

Exercise Tolerance and Recovery

Some evidence for ashwagandha (including Sensoril) supporting cardiorespiratory fitness markers.

Supported by Trial 1, Trial 2

Root + Leaf Standardization

Distinguishes from root-only ashwagandha extracts — leaf provides additional withanolide profile; comprehensive ashwagandha bioactives.

Supported by Trial 1

Mechanism of action

1

Adaptogenic HPA Axis Modulation

Modulates HPA axis (hypothalamic-pituitary-adrenal) — central stress response system; supports cortisol regulation without complete suppression.

2

Withanolide Bioactivity

Withanolides are steroidal lactones — primary ashwagandha bioactives; multiple withanolides contribute to clinical effects.

3

GABAergic Activity

Mild GABA pathway effects support calming without sedation; relevant to anxiety reduction and sleep.

4

Antioxidant Activity

Reduces oxidative stress; protects neuronal tissue.

5

Root + Leaf Comprehensive Profile

Sensoril's root + leaf approach captures withanolide types not found in root-only extracts; allows lower clinical doses.

Clinical trials

1
Sensoril for Stress

60-day clinical trial of Sensoril 125-500 mg/day in 130 chronically stressed adults.

130 chronically stressed adults.

In this trial, participants showed reductions in perceived-stress and self-reported anxiety and low-mood questionnaire scores, lower cortisol, and improved C-reactive protein versus placebo — reported as trial outcomes. Ashwagandha is used as a supplement for stress and mood support, not to diagnose, treat, or cure any disease.

2
Sensoril for Sleep Quality

Sensoril clinical trials on sleep quality and parameters.

Adults with sleep concerns.

Sleep quality improvements; sleep latency reductions.

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated in short-term trials. Do not use during pregnancy — ashwagandha has traditional abortifacient use and is considered contraindicated in pregnancy; also avoid while breastfeeding due to limited safety data.
Mild GI distress.
Drowsiness — relevant for evening dosing or stress applications.
Allergic reactions rare. Liver injury (hepatotoxicity): ashwagandha is a documented cause of drug-induced liver injury, including cholestatic hepatitis, with an NIH LiverTox entry and published case reports (some severe). Stop use and seek medical care if signs of liver trouble occur (jaundice, dark urine, unusual fatigue, nausea, or right-upper abdominal pain).
May raise thyroid hormone levels (T3/T4) — relevant for hyperthyroidism, existing thyroid disease, and anyone taking thyroid medication (risk of additive over-replacement); monitor thyroid status and consult a clinician.

Important Drug interactions

Thyroid medications — ashwagandha may modestly stimulate thyroid; relevant for hyperthyroidism (caution) or hypothyroidism (theoretical benefit but consult).
Sedatives — additive sedation possible.
Immunosuppressants — ashwagandha has immunomodulatory effects; theoretical interaction.
Diabetes medications — modest hypoglycemic effects.
Pregnancy — contraindicated in pregnancy (potential abortifacient effects); avoid.
Lactation — limited data; avoid.
Pre-surgery — discontinue 1-2 weeks before.
