Product Introduction

Ashwagandha Root Extract Capsules are extracted from the roots of Withania somnifera only, not a mixture of leaves and roots. This is important as the root includes a safer, clinically tested withanolide profile, while leaf material carries enhanced Withaferin A levels that may be lethal at greater quantities.

Standardisation: The extract is standardised by HPLC analysis to ensure that the withanolide content is 5% to 10% per batch. Particle size regulated to 95% through 80 mesh for constant capsule fill weight and mix consistency. Bulk density 0.3–0.6 g/ml, suitable for accurate encapsulation

"This solution solves typical formulation trouble points such as leaf material adulteration, variable bioactive indicators and poor potency raw powders. It’s a high-potency clean-label ingredient marketers can count on.”

Product Specification

Ashwagandha Root Extract Capsules Advantages

Root-only sourcing. Clinical trials supporting cortisol reduction, sleep improvement, and testosterone support are based on root extract. Hongda uses only root material to match that evidence base.

Verified withanolide levels. Standardization via HPLC means you get 5%–10% withanolides per batch — not an estimation based on extraction ratios. Your formulation potency stays consistent across production runs.

Controlled particle size. At 95% passing 80 mesh, the powder blends evenly in encapsulation machines. It reduces capping failures and weight variation — a practical benefit for high-volume manufacturers.

Clean label documentation. The product is free from the 8 major allergens. Non-GMO and Vegan certifications are available. Heavy metal levels comply with USP/EP pharmacopeial standards.

Stable under controlled humidity. The extract has an established stability profile. Hongda uses vacuum-sealed PE bags inside fiber barrels to protect against clumping caused by the extract's hygroscopic nature during storage and transit.

Ashwagandha Root Extract Capsules Application

Stress & sleep supplements. The primary use case. Withanolides support cortisol regulation and sleep quality. Typical dosing in capsule formulas runs 300mg–600mg per serving. The extract pairs well with Magnesium, Zinc, and L-Theanine without chemical instability.

Sports nutrition & recovery. Ashwagandha has clinical backing for testosterone support and muscle recovery. It is increasingly used in pre-workout and post-recovery blends. Micro-encapsulation is an option when blending with hygroscopic amino acids like Citrulline.

Functional gummies & beverages. The extract shows thermal stability up to approximately 100°C, making it suitable for pectin or gelatin gummy production. Water-soluble grades are available for liquid supplement applications.

Cognitive health formulas. Memory, focus, and mental fatigue are key positioning angles for this ingredient, particularly in nootropic capsule stacks targeting adults aged 30–55.

Production Process

Hongda's production follows a structured, traceable flow:

Raw material intake → Cleaning & drying → Solvent extraction → Filtration & concentration → Spray drying → Particle size control → HPLC standardization → Encapsulation → QC inspection → Packaging & shipment

The extraction facility includes 100,000-level purification workshops and more than 10 production lines. The SGS-standardized on-site laboratory runs HPLC, UV, and GC testing at each critical stage. Batch records are maintained for full traceability from raw root to finished capsule.

FAQ

Q1: Why only extract from root and not the entire plant?

A: Root-only material is the same source used in clinical trials. It also avoids large accumulation of Withaferin A in the leaves, which may be harmful at greater doses.

Q2: What is the HPLC standardisation of my formula?

A: Each batch is confirmed with HPLC for withanolide %. Unlike extraction ratios (eg 10:1), standardisation ensures active content and consistency of potency in your product.

Q3: What do you do about the hygroscopic nature of the powder in shipping?

A: We utilise natural anti-caking techniques, controlled particle size and vacuum sealed PE inner bags within fibre drums to preserve powder flowability throughout shipment and storage.

Q4: Is the extract suitable for use in vegan and allergen-free products?

Q. Yeah. Free of the 8 major allergens: Vegan and Non-GMO documentation is available upon request. 

Q5: Do you support any other custom dosage outside 500mg?

A: I do. Capsule fill weights are completely customisable. The OEM team can tailor to your goal formulation and regulatory market needs.

Q6. What is the minimum order quantity for private label products?

A: MOQ is flexible based on the specification. For an estimate based on your volume and packaging requirements, contact the Hongda team directly.
