Omega-3 Fatty Acids
Nutraceutical-Grade EPA & DHA Raw Materials for Dietary Supplement Applications
Omega-3 fatty acids are essential long-chain polyunsaturated fatty acids widely used in dietary supplements, functional foods and medical nutrition.
From an ingredient supplier’s perspective, Omega-3 is not a single product, but a controlled system of raw materials, processes and specifications, defined primarily by EPA and DHA content, molecular form and oxidation stability.
KosNature supplies nutraceutical-grade Omega-3 raw materials designed for professional formulators and manufacturers who require consistent purity, reliable supply and clear technical documentation.
What Is Omega-3 ？
Omega-3 fatty acids mainly refer to EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid) derived from marine fish oil sources.
In industrial and supplement manufacturing, Omega-3 materials are evaluated by:
EPA & DHA content (%)
Molecular form (EE / TG / rTG)
Oxidation control (PV, AV, TOTOX)
Stability during processing and encapsulation
Regulatory and food safety compliance
Unlike consumer-grade fish oil, nutraceutical-grade Omega-3 must maintain both compositional accuracy and long-term stability under manufacturing conditions.
Our Omega-3 Raw Material Positioning
We focus exclusively on B2B ingredient supply, not finished consumer products.
Our Omega-3 materials are designed for:
⇒Dietary supplement manufacturers
⇒Functional food producers
⇒Contract manufacturers (CDMO / OEM)
⇒Medical nutrition and specialized nutrition applications
All Omega-3 materials follow HACCP-based quality management, with purity and stability control aligned with nutraceutical industry requirements.
Molecular Forms Available: EE, TG and rTG
Different applications require different Omega-3 molecular structures. We support all major commercial forms:
Ethyl Ester (EE)
High concentration capability
Suitable for EPA-rich and DHA-rich formulations
Widely used in standardized supplement products
Triglyceride (TG)
Natural triglyceride structure
Improved stability and formulation compatibility
Common in premium nutraceutical formulations
Re-Esterified Triglyceride (rTG)
Combines high concentration with triglyceride structure
Enhanced oxidative stability
Suitable for high-end dietary supplement products
Selection of molecular form depends on formulation goals, target dosage and processing conditions.
EPA & DHA Coverage Range
Our Omega-3 portfolio covers a wide range of EPA-rich and DHA-rich compositions to support flexible formulation design.
EPA-Rich Omega-3
Balanced EPA/DHA ratios
High-EPA concentrates for cardiovascular and metabolic nutrition formulations
Available in multiple concentration ranges
→ Detailed EPA-focused materials are available on the EPA page
DHA-Rich Omega-3
High DHA concentrations for cognitive, visual and maternal nutrition
Stable DHA-dominant profiles
Suitable for both supplement and functional food systems
→ Detailed DHA-focused materials are available on the DHA page

Estabilidad & Oxidation Management
Omega-3 materials are inherently sensitive to oxidation. Stability is a core performance indicator.
Our Omega-3 ingredients are controlled through:
Valor de peróxido (PV) monitoring
Índice de acidez (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 + vitaminas, lutein or functional ingredients
Capsule options: gelatina, fish gelatin or plant-based shells
This module is intended to support formulation partners requiring integrated raw material and dosage form coordination.
Raw Material Selection & Processing Control
To ensure consistent quality, Omega-3 raw materials are managed from the earliest stages:
Carefully selected marine fish oil sources
Controlled purification processes
Mild processing conditions to preserve fatty acid structure
Continuous monitoring of oxidation parameters
Advanced purification and molecular transformation processes are applied to maintain chemical integrity while achieving targeted EPA/DHA concentrations.
