Algae DHA/Omega-3 Powder is a microalgae-derived source of DHA (docosahexaenoic acid), offering pet food manufacturers a sustainable, traceable alternative to fish oil for omega-3 fortification. Produced from Schizochytrium sp., it delivers a concentrated, standardized DHA content without the supply volatility, marine sourcing concerns, or oxidative instability commonly associated with conventional fish-based oils.
Functional properties
DHA is a long-chain omega-3 fatty acid with well-established roles in cognitive development, skin and coat health, and inflammatory balance in companion animals. As a microalgae-derived source, this ingredient provides DHA further up the supply chain than fish oil — algae are the primary producers of omega-3s in the marine food web — supporting formulations that require a vegetarian-compatible or non-fish marine fatty acid source.
The powder format also offers handling and stability advantages over liquid fish oils, reducing the risk of oxidation and off-odors during storage and processing, while simplifying inclusion in dry formulation systems.
Composition and specifications
This DHA 20% Powder is standardized to a minimum of 20.0% DHA (result: 20.8%, tested by GC) and a minimum of 30.0% total omega-3 fatty acids (result: 31.6%). Total fat content is a minimum of 50.0% (result: 55.3%), with moisture controlled at or below 5.0% (result: 2.8%).
Oxidative stability is confirmed through peroxide value (≤5.0 meq/kg specification, result: 2.1 meq/kg) and acid value (≤3.0 mg KOH/g specification, result: 1.2 mg KOH/g), both well within specification. Particle size conforms to 100% pass through 80 mesh, supporting uniform dispersion in dry mix systems.
Quality and compliance
Each batch is tested for a comprehensive contaminant panel, including heavy metals (arsenic, lead, mercury, cadmium), dioxins (PCDDs/Fs), dioxin-like PCBs, and PAHs — all confirmed well within specification (EU-PF-2024 specification version). Full microbiological testing (Total Plate Count, yeast and mold, Enterobacteriaceae, E. coli, and Salmonella) confirms compliance, and the product is certified free of gluten, soy, and dairy by ELISA testing.
The product complies with Regulation (EC) No 767/2009 on the placing on the market and use of feed, Regulation (EC) No 1831/2003 on additives for use in animal nutrition, and Regulation (EC) No 1881/2006 on maximum levels for certain contaminants in foodstuffs. Shelf life is 24 months from the manufacture date.
Formulation usability
As a concentrated, standardized powder, inclusion rates are typically low and calculated based on the target DHA or total omega-3 level in the finished formulation. The powder format integrates readily into dry extrusion and supplement powder systems, and its documented oxidative stability supports predictable shelf-life performance in the finished product without the handling complexity of liquid oil inclusion.
Sourcing and origin
Our algae DHA powder is sourced from a specialized biotechnology manufacturer in Jiangsu, China, using controlled fermentation of Schizochytrium sp. rather than wild-harvested marine biomass. This production method decouples DHA supply from fish stock variability and marine harvesting pressures, supporting a more traceable and consistent sourcing model for manufacturers with sustainability commitments.
Certificates of analysis and additional supporting documentation are available on request to support incoming quality assurance processes.
Market positioning
Omega-3 fortification remains a strong driver of premium and functional pet food positioning, and algae-derived DHA allows manufacturers to meet this demand while addressing growing consumer and buyer interest in sustainable, non-fish marine ingredient sourcing. It is well suited to formulations targeting cognitive support, skin and coat health, and puppy or senior life-stage products, as well as brands seeking to differentiate their omega-3 sourcing story from conventional fish oil.
We supply algae DHA/Omega-3 powder in bulk quantities suited to industrial pet food 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.
