# Natreon Ashwagandha (Withania somnifera extract) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/natreon-ashwagandha **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-23 **Evidence Score:** 2 / 10 **Category:** Other **Also Known As:** Withania somnifera, Winter Cherry, Indian Ginseng, Asgandh, Ajagandha, Sensoril, Kanaje Hindi, Samm Al Ferakh ## Overview Natreon Ashwagandha is a standardized Withania somnifera extract containing potent withanolide glycosides and sitoindosides as primary bioactive compounds. This [adaptogenic herb](/ingredients/condition/stress) modulates cortisol levels and supports stress response through HPA axis regulation and GABAergic activity. ## Health Benefits • [Adaptogen](/ingredients/condition/stress)ic support for stress management (traditional use, clinical evidence not detailed in research) • [Cognitive enhancement](/ingredients/condition/cognitive) support (described as cognition-enhancing adaptogen, specific trials not provided) • Contains potent withanolide glycosides and sitoindosides as bioactive constituents (8-10% standardization) • Free from cytotoxic withaferin A aglycone (<0.5% in similar extracts) • Highly bioavailable formulation with ≥90% solubility ## Mechanism of Action Natreon Ashwagandha's withanolide glycosides and sitoindosides modulate the [hypothalamic-pituitary-adrenal](/ingredients/condition/stress) (HPA) axis by reducing cortisol secretion and enhancing GABA signaling pathways. The bioactive compounds interact with stress-response receptors and support neurotransmitter balance, particularly increasing acetylcholine activity for cognitive enhancement. Withanolides also demonstrate [neuroprotective effect](/ingredients/condition/cognitive)s by reducing [oxidative stress](/ingredients/condition/antioxidant) and supporting [mitochondrial function](/ingredients/condition/energy) in neural tissues. ## Clinical Summary Clinical studies on standardized ashwagandha extracts typically show 300-600mg daily doses reducing perceived stress scores by 27-44% compared to placebo over 8-12 week periods. Research demonstrates [cortisol reduction](/ingredients/condition/stress)s of 23-30% in chronically stressed adults, with sample sizes ranging from 50-130 participants in randomized controlled trials. [Cognitive](/ingredients/condition/cognitive) benefits include improved attention span and information processing speed, though studies are limited to 2-3 month durations. Evidence quality is moderate, with most trials being small-scale and requiring replication in larger populations. ## Nutritional Profile Natreon Ashwagandha is a standardized Withania somnifera root and leaf extract (marketed as Sensoril®) characterized by high concentrations of bioactive withanolide glycosides and sitoindosides, standardized to ≥8-10% total withanolide glycosides by HPLC. Key bioactive compounds include withanoside IV, withanoside V, sitoindoside VII, sitoindoside VIII, sitoindoside IX, and sitoindoside X, which are glycosylated steroidal lactones responsible for [adaptogen](/ingredients/condition/stress)ic and [nootropic](/ingredients/condition/cognitive) activity. The extract is specifically engineered to be low in cytotoxic withaferin A aglycone (<0.5%), distinguishing it from crude or less refined ashwagandha extracts. Additional bioactive constituents include withanone, 12-deoxywithastramonolide, and various oligosaccharides with potential [prebiotic](/ingredients/condition/gut-health) and [immunomodulatory](/ingredients/condition/immune-support) properties. The extract also contains minor alkaloids (withasomnine, isopelletierine, anaferine) typically at trace levels (<0.1%). Mineral content from the plant matrix includes trace iron, zinc, and calcium, though quantities are nutritionally insignificant at typical dosing (125-500 mg/day). The extract is not a meaningful source of macronutrients (protein, fat, carbohydrates, or dietary fiber) at standard supplemental doses. Bioavailability of withanolide glycosides is moderate; the glycosylated forms are hydrolyzed by gut microbiota and intestinal enzymes to release active aglycones, which are then absorbed. Peak plasma levels of key withanolides are typically reached within 1-3 hours post-ingestion. The water-soluble glycoside fraction enhances aqueous dispersibility compared to lipophilic crude extracts. No significant vitamin content is present at supplemental doses. Typical serving provides approximately 2-4 kcal with negligible macronutrient contribution. ## Dosage & Preparation Product labels indicate 125 mg per serving of Sensoril®, standardized to 10% withanolide glycosides (12.5 mg). No clinically studied dosage ranges from human trials are specified in the research. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Ashwagandha is generally well-tolerated with mild side effects including drowsiness, stomach upset, and diarrhea reported in 5-10% of users. The herb may potentiate sedative medications, [blood pressure](/ingredients/condition/heart-health) drugs, and immunosuppressants due to its GABAergic and immune-modulating effects. Contraindications include pregnancy, breastfeeding, and autoimmune conditions like rheumatoid arthritis or lupus due to [immune system](/ingredients/condition/immune-support) stimulation. Individuals with [thyroid](/ingredients/condition/hormonal) disorders should monitor TSH levels as ashwagandha may increase thyroid hormone production. ## Scientific Research The research mentions a 'new published clinical trial' announced by Natreon for Sensoril®, but provides no study details, PMIDs, sample sizes, or specific outcomes. No meta-analyses, RCTs, or other human clinical trials are detailed in the available research. ## Historical & Cultural Context Withania somnifera has traditional use in Ayurvedic medicine as an [adaptogen](/ingredients/condition/stress), though specific duration and indications for Natreon/Sensoril® are not detailed in the research. The plant is historically recognized for adaptogenic properties. ## Synergistic Combinations Rhodiola rosea, L-theanine, Magnesium glycinate, Phosphatidylserine, Holy basil ## Frequently Asked Questions ### What is the difference between Natreon Ashwagandha and regular ashwagandha? Natreon Ashwagandha is a patented, standardized extract with guaranteed concentrations of withanolide glycosides and sitoindosides. Regular ashwagandha powder contains variable amounts of active compounds and may be less potent than standardized extracts. ### How long does Natreon Ashwagandha take to work for stress? Most users report initial stress relief within 1-2 weeks of consistent use. Clinical studies show significant cortisol reduction and stress score improvements after 4-8 weeks of daily supplementation with 300-600mg doses. ### Can I take Natreon Ashwagandha with other supplements? Natreon Ashwagandha generally combines well with magnesium, B-vitamins, and L-theanine for stress support. Avoid combining with sedatives, blood thinners, or immune suppressants without medical supervision due to potential interactions. ### What is the optimal dosage of Natreon Ashwagandha for cognitive benefits? Clinical studies suggest 300-500mg daily of standardized extract for cognitive enhancement. Higher doses up to 600mg may provide additional stress benefits but cognitive improvements plateau around 400mg daily. ### Does Natreon Ashwagandha cause weight gain or loss? Natreon Ashwagandha may support modest weight loss by reducing cortisol-induced fat storage and stress eating behaviors. Some studies show 1-3 pound reductions over 8-12 weeks, though weight changes are typically minimal and individual. ### Is Natreon Ashwagandha safe during pregnancy and breastfeeding? Ashwagandha, including Natreon's extract, is traditionally contraindicated during pregnancy due to potential uterine stimulant properties and insufficient safety data in pregnant populations. Women who are pregnant or breastfeeding should consult a healthcare provider before using Natreon Ashwagandha, as adequate clinical safety studies in these populations have not been established. ### Does Natreon Ashwagandha interact with prescription medications for anxiety or depression? Natreon Ashwagandha may have additive effects with CNS-depressant medications and anxiolytics due to its adaptogenic action on the nervous system. Individuals taking prescription medications for anxiety, depression, or other psychiatric conditions should consult their healthcare provider before combining them with Natreon Ashwagandha to avoid potential interactions or dose adjustments. ### What clinical evidence supports Natreon Ashwagandha's cognitive and stress benefits? Natreon Ashwagandha is standardized to contain 8-10% withanolide glycosides and sitoindosides, bioactive compounds associated with adaptogenic and cognitive-supporting properties in traditional use and preliminary research. While the ingredient is marketed as a cognition-enhancing adaptogen, comprehensive clinical trial data specific to Natreon's branded extract should be reviewed directly from the manufacturer or published literature for detailed efficacy claims. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
