EPA (Eicosapentaenoic Acid) Raw Material
High-Purity Algal EPA & EPA+DHA Concentrates for Nutraceutical Applications
EPA (Eicosapentaenoic Acid) is a long-chain Omega-3 fatty acid widely used in dietary supplements and functional nutrition products.
Compared with conventional low-concentration Omega-3 oils, high-purity EPA concentrates offer improved formulation flexibility, dosage accuracy and product differentiation.
KosNature supplies nutraceutical-grade algal EPA and EPA+DHA concentrates, produced from selected algal sources using advanced molecular distillation and high-vacuum purification technologies.
What Is EPA (From a Raw Material Perspective)？
EPA is one of the two primary Omega-3 fatty acids used in supplement manufacturing, alongside DHA.
From an ingredient supplier’s standpoint, EPA materials are evaluated by:
EPA content (%)
EPA to DHA ratio
Molecular purity and stability
Sensory profile (taste & odor)
Long-term oxidative stability
Algal EPA offers a plant-based, sustainable alternative to marine fish oil while enabling higher purity levels through controlled upstream fermentation and downstream purification.
Why Choose Algal EPA Instead of Conventional Fish Oil EPA
Compared with low-concentration fish oil EPA/DHA, algal-derived EPA concentrates provide:
⇒ Higher achievable EPA purity
⇒ Improved batch-to-batch consistency
⇒Cleaner sensory profile
⇒Better differentiation for premium supplement brands
⇒Strong sustainability positioning
These advantages make algal EPA particularly suitable for high-end nutraceutical formulations.

Processing & Purification Technology
Our algal EPA materials are produced using:
Carefully selected algal raw materials (sourced from the U.S., Europe and China)
Advanced molecular distillation
Ultra-high vacuum purification
Controlled low-temperature processing
This approach preserves molecular integrity while achieving high EPA and EPA+DHA concentrations, ensuring reliable stability and formulation performance.
Stability & Oxidation Management
Omega-3 materials are inherently sensitive to oxidation. Stability is a core performance indicator.
Our Omega-3 ingredients are controlled through:
過酸化物価 (PV) monitoring
酸価 (AV) control
TOTOX management
Batch-to-batch consistency verification
Controlled storage and packaging conditions
These controls ensure the material remains suitable for downstream processing such as blending, filling and encapsulation.
Omega-3 Softgel OEM Capability
In addition to raw materials, we offer optional Omega-3 softgel OEM support for qualified partners.
This capability includes:
EPA/DHA-based formulations
Omega-3-6-9 blends
Omega-3 + vitamins, lutein or functional ingredients
Capsule options: ゼラチン, fish gelatin or plant-based shells
This module is intended to support formulation partners requiring integrated raw material and dosage form coordination.
Stability & 品質管理
EPA concentrates are sensitive to oxidation and require strict quality management.
Our materials are controlled through:
Oxidation parameter monitoring
Sensory evaluation
Process-level purity control
Batch consistency verification
Quality management follows nutraceutical-grade standards to support downstream encapsulation and formulation processes.
Typical Applications
Algal EPA and EPA+DHA concentrates are widely used in:
Dietary supplements
Functional nutrition products
High-purity Omega-3 formulations
Premium and differentiated supplement lines
These materials are designed for professional manufacturers requiring reliable specifications and technical support.
