Ashwagandha Extract Factory

Our Ashwagandha extract is made from the finest Withania somnifera roots and extracted using precise techniques to concentrate the withanolides to therapeutically relevant levels. This brown-yellow powder is standardised to 5% withanolides and made with a 10:1 extraction ratio, offering outstanding solubility in both water and alcohol-based formulations. Ashwagandha root powder has less than 0.5% actives whereas our concentrated extract may be dosed effectively at just 300-600mg per day. This makes it perfect for single-capsule formulations and multi-ingredient blends focused on stress reduction, cognitive support and athletic performance improvement.

Ashwagandha Concentrated Extract Powder Advantages

HPLC-validated assay technology enables precise withanolide measurement, eliminating false inflation and ensuring formulation dependability across manufacturing batches.

Higher Bioavailability: Our concentrated extraction method removes fibrous inert material but retains oligosaccharides that promote active chemical absorption, resulting in therapeutic benefits at lower dosages than raw powder counterparts

Great Flowability: 0.40–0.50 g/ml bulk density and 80 mesh particle size enable easy integration into high-speed encapsulation equipment without bridging or weight fluctuation.

Improved Sensory Profile: Better processing reduces the typical earthy bitterness of raw ashwagandha root, facilitating flavour masking for beverage applications and boosting customer compliance of final goods.

Ashwagandha Concentrated Extract Powder Dosage

Stress Relief Supplements: Available in both capsule and tablet forms, they are designed to help manage cortisol and relieve anxiety. They provide adaptogenic effects for those dealing with the stressors of contemporary life and chronic stress disorders.

Sports Performance Products: Incorporated into pre-workout and recovery powders to optimise testosterone, increase muscular strength, and boost endurance for athletic individuals seeking natural performance benefits.

Functional Beverage Systems: Ashwagandha PowderUsed in adaptogenic beverages, sleep-aid mocktails and wellness shots where our water-soluble grade is stable during pasteurisation with no withanolide degradation or apparent sedimentation.

Cognitive Health Formulas: Blended with nootropic compounds in focus-enhancing supplements to support brain clarity, memory function and neuroprotective effects for ageing populations and productivity-driven customers.

Process of Manufacture

Step 1 - Selection of Raw Material: Procure the superior quality roots of Withania somnifera from the recognised cultivation sites. Botanical verification for the confirmation of species validity. The qualified raw material should conform to the pharmacopoeial requirements.

Step 2 - Extraction Optimisation: Controlled temperature and pressure hydro-ethanol extraction of roots, concentrating bioactive withanolides to target specifications for a more potent crude extract

Step 3 – Purification & Refinement: Filter extract using membrane separation systems to remove contaminants and inert chemicals. Spray-dry concentrated liquid under vacuum conditions, resulting in fine powder with maintained bioactivity.

Step 4 – Quality Verification: Conduct extensive HPLC assay testing, heavy metal screening and microbiological analysis for each manufacturing batch, confirming conformity with international standards, approving certified Ashwagandha Concentrated Extract Powder for distribution.

Third Test Report

Testing Authority: SGS and Eurofins laboratories test our products for international conformity and quality.

ICP-MS screening for heavy metals shows Lead <0.5ppm, Arsenic <1ppm, Cadmium <0.3ppm, and Mercury <0.1ppm exceeding USP <232> standards. Pesticide residue testing for over 70 agricultural agents in compliance with USP <561> criteria is below EU MRL limits.

Microbiological Safety: Maintain <1000 CFU/g Total Aerobic Microbial Count to ensure safe eating without harmful organisms including E. coli, Salmonella, and S. aureus.

Botanical Verification: HPTLC fingerprinting verifies Withania somnifera root identity, while DNA barcoding eliminates leaf adulteration for reliable botanical traceability.

FAQ

Q: What is the extraction ratio you use for this product?

A: We employ a 10:1 extraction ratio (standardised to 5% withanolides) which means 10kg of dried roots will produce 1kg of concentrated extract.

Q: Do you have water soluble grades for beverage applications?

A: Yes, we offer specialized water-soluble formulations using spray-drying technology with carrier matrices that maintain stability in acidic pH environments without sedimentation.

Q: What is your minimum order quantity?

A: Our standard MOQ is 25kg (one drum), though we can accommodate sample requests from 20-100g for formulation testing purposes before bulk ordering.

Q: How do you ensure withanolide content accuracy?

A: We exclusively use HPLC methodology per USP monograph standards, rejecting gravimetric testing that can inflate values by including non-withanolide constituents in measurements.

Q: Do you offer organic certified ashwagandha extract?

A: Absolutely. We maintain both ORGANIC (EU) and ORGANIC (NOP) certifications, with products sourced from our certified organic cultivation bases meeting all regulatory requirements.
