Sensoril Withania Somnifera
Also known as: Withania somnifera, Ashwagandha, Indian ginseng, Winter cherry, Sensoril, Withania somnifera (Sensoril)
Overview
Sensoril is a proprietary extract of Withania somnifera, a plant traditionally used in Ayurvedic medicine for its adaptogenic properties. It is primarily used to reduce stress, anxiety, and improve sleep quality, as well as to enhance physical performance and cognitive function. Sensoril contains a standardized concentration of withanolides, the active phytochemicals believed to mediate its effects. Research on Withania somnifera is moderately mature, with multiple randomized controlled trials (RCTs) and meta-analyses supporting its efficacy, though studies specifically on Sensoril are fewer and often extrapolated from broader Ashwagandha research. It is available in various forms, most commonly as capsules, and is derived from the roots and leaves of the Withania somnifera plant.
Benefits
Withania somnifera extracts, including Sensoril, have demonstrated several evidence-based benefits. Multiple RCTs and a systematic review indicate significant reductions in stress and anxiety levels; a 60-day RCT showed significant improvements in Perceived Stress Scale scores and cortisol reduction at a 600 mg/day dosage (p < 0.0001). A meta-analysis found Ashwagandha extract significantly improved overall sleep quality compared to placebo (SMD -0.59; p < 0.001). Ashwagandha supplementation has also been associated with improved VO2max, a marker of aerobic capacity. A recent study demonstrated that aqueous extracts of Withania somnifera at doses of 125-500 mg/day over 8 weeks safely reduce mild to moderate chronic stress. Benefits generally manifest within 4 to 8 weeks of supplementation.
How it works
Sensoril's mechanism of action involves several biological pathways. Withanolides modulate the hypothalamic-pituitary-adrenal (HPA) axis, reducing cortisol secretion and thereby attenuating stress responses. Ashwagandha may enhance GABAergic activity, contributing to anxiolytic and sleep-promoting effects. Its anti-inflammatory and antioxidant effects contribute to neuroprotection and improved physiological resilience under stress. Sensoril is standardized for bioavailability, but specific pharmacokinetic data are limited. Generally, withanolides are absorbed orally with moderate bioavailability.
Side effects
Withania somnifera extracts, including Sensoril, are generally safe and well-tolerated in adults. Mild gastrointestinal discomfort and drowsiness occur in fewer than 5% of users. No serious adverse events have been reported in high-quality trials. Potential interactions with sedatives, thyroid hormone, and immunosuppressants warrant caution. It is generally advised against use during pregnancy, breastfeeding, and in individuals with autoimmune diseases due to insufficient safety data. Limited data exists for special populations; caution is advised in children and those with chronic illnesses. It is important to consult with a healthcare provider before starting Sensoril, especially if you have any pre-existing health conditions or are taking medications.
Dosage
The minimum effective dose for stress reduction is approximately 125 mg/day of an aqueous extract. The optimal dosage range is 250–600 mg/day of a standardized extract, with 600 mg/day commonly used in anxiety and stress RCTs. Studies have used up to 12,000 mg/day with no serious adverse effects, but such high doses are not typical or recommended. Divided doses with meals may improve tolerability and absorption. Sensoril is a standardized extract, often available in capsule form. No specific cofactors are required, but general good nutritional status supports efficacy.
FAQs
Is Sensoril safe for long-term use?
Current evidence supports safety up to 8 weeks; longer-term data are limited but no serious adverse effects reported.
How soon will I notice benefits?
Improvements in stress and sleep often appear within 4–8 weeks.
Can Sensoril cause sedation?
Mild drowsiness is possible but uncommon.
Is Sensoril better than other Ashwagandha extracts?
Sensoril is standardized for higher withanolide content, potentially offering more consistent effects, though direct comparative trials are lacking.

- https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0257843 – This meta-analysis of 5 RCTs with 1764 participants found that Ashwagandha extract significantly improved sleep quality compared to placebo (SMD -0.59; p < 0.001). The study highlights the potential of Ashwagandha as a natural sleep aid, although it notes moderate heterogeneity and varying sleep measures across the included trials.
- https://www.liebertpub.com/doi/full/10.1089/acm.2014.0177 – This systematic review of human trials, including a 64-participant 60-day trial at 600 mg/day, showed significant reductions in anxiety and cortisol levels (p < 0.0001) with Ashwagandha supplementation. The review suggests that Ashwagandha is a safe and well-tolerated option for reducing anxiety, although some trials had small sample sizes.
- https://www.mdpi.com/2072-6643/16/9/1293 – This recent randomized controlled trial demonstrated a dose-dependent reduction in stress at 125–500 mg/day of aqueous Withania somnifera extract over 8 weeks in adults with mild to moderate chronic stress. The study found no safety concerns, supporting the use of Ashwagandha for stress management in this population.
- https://www.mdpi.com/2072-6643/12/4/1119 – This meta-analysis of 5 studies (162 participants) found that Ashwagandha supplementation improves aerobic capacity (VO2max). The study provides moderate evidence supporting the benefits of Ashwagandha for physical performance, although it notes the small sample size and heterogeneous study designs.
