Astragalus polysaccharides are a concentrated functional extract derived from the root of Astragalus membranaceus, a botanical widely recognized for its immune-supporting properties. Increasingly used in functional and condition-specific pet food and supplement formulations, astragalus polysaccharides offer manufacturers a botanical ingredient with a strong evidence base and growing consumer recognition.
Functional properties
Astragalus polysaccharides are primarily valued for their immunomodulating activity, supporting general immune function and vitality in companion animals. They are commonly included in formulations targeting senior animals, immune support diets, and general wellness or vitality product lines, where a botanical active ingredient adds functional and marketing value.
As a water-soluble extract, astragalus polysaccharides integrate readily into both dry and liquid formulation systems, supporting their use across a range of finished product formats, including functional treats, powders, and supplements.
Composition and specifications
Our astragalus polysaccharide extract is standardized to a minimum of 70.0% polysaccharide content on a dry basis, with a typical result of 72.6% — confirming a high-potency, standardized active ingredient. The extract is supplied as a light yellow to brown fine powder, characteristic in odor, fully soluble in water, with moisture at or below 8.0% (typical result: 4.6%) and ash content at or below 5.0% (typical result: 2.1%).
Protein content is controlled at or below 5.0% (typical result: 2.3%), reflecting a well-purified polysaccharide fraction with minimal residual protein carryover from the extraction process.
Formulation usability
Given its high potency, astragalus polysaccharide extract is typically included at low inclusion rates as a functional active ingredient, with exact dosage depending on the target health claim and finished product format. Its water solubility supports easy incorporation into liquid and powder formulations, as well as standard dry processing systems, without requiring specialized handling.
Quality and compliance
Each batch is supplied with a full Certificate of Analysis, confirming compliance with EU Regulation (EC) No. 2017/2283 on feed additives and Regulation (EC) No. 1881/2006 on contaminants in feed. Heavy metals (lead, arsenic, cadmium, and mercury) are controlled well within specification, and the product is certified non-GMO and non-irradiated.
Microbiological testing covers Total Plate Count, yeasts and molds, E. coli, and Salmonella, all conforming to specification. The product is explicitly certified as suitable for pet food and pet supplement use, and is supplied in 25 kg drums with a shelf life through the stated expiry date when stored in a cool, dry place, protected from light and moisture.
Sourcing and origin
Our astragalus polysaccharides are sourced from a specialized biotech manufacturer in Shandong, China, a region with established expertise in botanical extraction and standardization. Working with a certified, quality-controlled manufacturer allows us to ensure consistent potency and purity across batches, backed by full documentation for every shipment.
Certificates of analysis and additional supporting documentation are available on request to support incoming quality assurance processes.
Market positioning
Functional and condition-specific pet food is a fast-growing segment, driven by pet owners increasingly seeking supplement-grade, evidence-based ingredients for their animals’ health and longevity. Astragalus polysaccharides allow manufacturers to address this demand with a standardized botanical active ingredient that supports clear, defensible functional claims around immune health and vitality.
We supply astragalus polysaccharide extract in bulk quantities suited to industrial pet food and supplement production, with flexible contract terms based on expected volumes and delivery schedules. Product specifications, samples, and current pricing are available on request through our procurement team.
