Ashwagandha Root Extract & Panchang Extract
5% Withanolides (HPLC)
Botanical Source :
Withania somnifera Dunal --- Root-only grade (classical) \| Panchang grade (root + leaf + stem + fruit + seed)
Key Active :
Withanolides (steroidal lactones) --- Withaferin A, Withanolide A, Withanolide D; plus sitoindosides and alkaloids
Standardisation :
5.0% total withanolides by HPLC (USP method) --- the highest-validated standardisation tier.

Mechanism of Action
HPA-axis normalisation --- withanolides reduce excessive cortisol secretion by modulating hypothalamic-pituitary-adrenal axis activity. A 2024 meta-analysis of 9 RCTs (558 patients, Arumugam et al., Explore 2024) demonstrated a significant effect on the Perceived Stress Scale with MD = −4.72 (95% CI: −8.45 to −0.99). (2) GABAergic and serotonergic facilitation --- withanolides interact with GABA-A receptors and modulate serotonin pathways, the basis for Ashwagandha\'s validated anxiolytic and sleep-promoting activity. (3) NF-κB and immunomodulation --- Withaferin A inhibits NF-κB transcription, suppresses inflammatory cytokines, and upregulates NK-cell and T-helper function.

Root-only vs Panchang : Root-only extract (classical Ayurvedic grade) delivers higher withanolide concentration from a narrower, well-characterised matrix; preferred for pharmaceutical and premium nutraceutical formulations. Panchang grade incorporates the full plant spectrum including leaf alkaloids (somniferine) and additional phytoconstituents; preferred for Ayurvedic-positioned products where whole-plant synergy is part of the formulation rationale.
Top 3 Applications
1. Nutraceuticals / Adaptogens --- Stress, Cortisol & Cognitive Support
A 2023 RCT (Majeed M et al., Medicine 2023) confirmed that ARE (500 mg, 2.5% withanolides) significantly reduced cortisol and improved GAD-7 and PSS scores in adults with mild-to-moderate stress. The 5% withanolide root extract provides the highest standardised withanolide density commercially available, enabling effective dosing at 300--500 mg. \[PubMed 37832082\]
2. Sports Nutrition / Performance --- Strength, VO₂max & Testosterone Support
Multiple RCTs confirm Ashwagandha root extract significantly improves muscle strength (upper and lower body), VO₂max, and serum testosterone in healthy males. The Panchang grade is particularly suited to Ayurvedic sports products where whole-plant traditional credentials enhance brand positioning.
3. Pharma / Functional Medicine --- Neuroprotection, Thyroid & Immunomodulation
Withanolides demonstrate AChE inhibition and amyloid-β clearance relevant to Alzheimer\'s research. Separate RCT evidence supports Ashwagandha root extract in improving subclinical hypothyroidism (T3 / T4 normalisation) and NK-cell-mediated immune support.
