Ashwagandha root extract standardised for withanolide content, available as full-spectrum and high-assay grades for the adaptogen and supplement markets.
Full-spectrum and standardised root extracts, with withanolide content controlled by gravimetry and HPLC.
Ashwagandha (Withania somnifera) is one of the most important adaptogenic botanicals in Ayurveda and one of the fastest-growing ingredients in the global supplement market. CTA manufactures root-based extracts standardised for total withanolides, with assay control by both gravimetry and HPLC.
Our process library covers multiple grades — from a water-extracted full-spectrum root extract that preserves the native withanolide profile, to higher-assay concentrates. Withaferin-A-controlled grades can be produced where buyers require a defined limit. Each route is documented as a process flow so that batches are reproducible.
CTA supplies Ashwagandha across multiple grades. Custom specifications are developed against a documented buyer requirement.

CTA's ashwagandha programme is supported by documented process flows and multiple purified-fraction grades:
A documented process library is what separates a speciality product from a commodity — it makes grades reproducible and lets CTA develop a custom specification with confidence.
Statements describe traditional use and the role of the active in normal body function. They are structure–function statements and not claims to diagnose, treat, cure or prevent any disease.

Ashwagandha is permitted under FSSAI and AYUSH and is widely accepted in major supplement markets. Root-only declarations, allergen statements and grade documentation are provided on enquiry.
Note: grades, marker percentages and regulatory status are indicative and to be confirmed by CTA's technical and regulatory team before publication.
Our standard speciality grades are root-based. Aerial-part or whole-plant material is only used where a buyer specifically requests it; the source is always declared on documentation.
Full-spectrum extract is water-extracted to preserve the native withanolide profile at a lower concentration. Standardised grades are concentrated to a fixed withanolide percentage (1.5%, 2.5% or 5%) for a declarable active load.
Yes. CTA can process to a defined withaferin-A specification where a buyer's dossier requires it.
