Product Info
What is Fish Oil DHA?
Fish Oil DHA is a concentrated essential omega-3 fatty acid extracted from fish oil, primarily used as a dietary supplement to support cognitive development, vision, and cardiovascular health.
How is Fish Oil DHA made?
| Step No. | Production Stage | Key Action | Control Point & Note |
|---|---|---|---|
| 1 | Raw Material Sourcing | Receiving fresh, omega-3 rich fish (e.g., anchovies, sardines, mackerel). | Control Point: Fish species verification, freshness assessment (TVB-N levels), and catch area traceability. Note: Sourcing from certified sustainable fisheries is a critical quality and ethical standard. |
| 2 | Crude Oil Extraction | Cooking, pressing, and centrifuging the fish to separate the crude oil from solids and water. | Control Point: Cooking temperature and duration must be minimized to prevent lipid oxidation. Low-temperature processing is preferred. Centrifuge speed must be optimized for efficient separation. |
| 3 | Refining & Purification | Performing degumming, neutralization, and bleaching to remove impurities like phospholipids, free fatty acids (FFAs), and color pigments. | Control Point: FFA levels are monitored closely. The concentration of refining agents and contact time must be strictly controlled to purify the oil without damaging the omega-3s. |
| 4 | Winterization | Chilling the refined oil to crystallize saturated fats and waxes, which are then removed via filtration. | Control Point: Precise cooling temperature and holding time are essential for effective crystallization. Filtration pressure is controlled to ensure clear oil. |
| 5 | Molecular Distillation | Using high vacuum and short-path distillation to separate and concentrate DHA and EPA fatty acids from other components. | Control Point: This is the most critical step. High vacuum, controlled temperature, and feed rate are vital to prevent thermal degradation of the delicate DHA molecules. The DHA/EPA concentration is tested post-distillation. |
| 6 | Deodorization | Injecting steam into the oil under high vacuum to strip away any remaining volatile compounds that cause fishy odor and taste. | Control Point: Minimal residence time at high temperature is key. The balance of steam, temperature, and vacuum must be perfect to remove odors without damaging the final product. |
| 7 | Stabilization & Blending | Adding natural antioxidants (like mixed tocopherols or rosemary extract) to the concentrated oil to prevent future oxidation and ensure stability. | Control Point: Accurate antioxidant dosage and homogeneous mixing are crucial for shelf life. Oil stability is verified by testing Peroxide Value (PV) and Anisidine Value (AV). |
| 8 | Final QC & Packaging | Conducting final analysis for potency (DHA/EPA levels) and purity (heavy metals, PCBs, dioxins). The oil is then bottled or encapsulated. | Control Point: Must pass all safety and purity specifications. Heavy metal testing (mercury, lead, arsenic) is mandatory. Packaging must occur under a nitrogen blanket to displace oxygen and prevent oxidation. |

Applications & Usage
Common Applications:
Dietary supplements
infant formula
functional foods
beverages
nutraceuticals
Mechanism of action:
| Parameter | Fish Oil DHA |
|---|---|
| Functional Category | Nutraceutical; Bioactive Lipid Source; Nutritional Fortificant |
| Key Ingredients | Docosahexaenoic Acid (DHA); Eicosapentaenoic Acid (EPA); Omega-3 Polyunsaturated Fatty Acids (PUFAs) |
| Mechanism of Action | Incorporates into phospholipid cell membranes, increasing fluidity and modulating cell signaling pathways; serves as a primary structural component of the brain and retina; acts as a precursor to anti-inflammatory lipid mediators (resolvins, protectins); influences gene expression related to lipid metabolism and inflammation. |
| Application Effect in Product | Fortifies foods (e.g., infant formula, milk, beverages) to support cognitive development and visual acuity; enhances the nutritional profile of dietary supplements for brain, cardiovascular, and joint health; provides a source of essential fatty acids that the human body cannot efficiently synthesize. |
Comparison:
| Product Name | Category/Type | Key Features | Strengths (vs peers) | Weaknesses (vs peers) | Best Use Cases | Why Choose |
|---|---|---|---|---|---|---|
| Fish Oil DHA | Omega-3 Supplement (Marine Source) | Contains pre-formed DHA and EPA (eicosapentaenoic acid) from oily fish tissue. | Cost-effective; high concentration of DHA/EPA; extensively researched for broad health benefits. | Can cause 'fish burps'; not suitable for vegans; potential for heavy metal contaminants (brand dependent). | General cognitive function, prenatal health, cardiovascular support, and reducing inflammation. | For a potent, well-studied, and affordable source of both DHA and EPA without dietary restrictions. |
| Krill Oil | Omega-3 Supplement (Crustacean Source) | DHA and EPA are bound to phospholipids; contains the antioxidant astaxanthin. | Potentially higher bioavailability; less likely to cause digestive upset; added antioxidant benefits. | Significantly more expensive; lower concentration of omega-3s per capsule compared to fish oil. | Individuals who experience digestive issues with fish oil or want the added benefit of astaxanthin. | To prioritize absorption and antioxidant content, and if you are willing to pay a premium for fewer side effects. |
| Algal Oil (Algae Oil) | Omega-3 Supplement (Plant-based Source) | Derived from microalgae; contains pre-formed DHA, sometimes with EPA. The original source of omega-3s in the food chain. | Vegan and vegetarian friendly; environmentally sustainable; free from ocean-borne contaminants like mercury. | Generally more expensive than fish oil; may have lower EPA content depending on the formulation. | Vegans, vegetarians, people with fish allergies, or those concerned with purity and environmental impact. | If you require a plant-based source of direct DHA or are concerned about pollutants in fish. |
| Cod Liver Oil | Omega-3 Supplement (Fish Liver Source) | Contains DHA and EPA, plus naturally occurring Vitamin A and Vitamin D. | Provides three key nutrients in one supplement (Omega-3, Vit A, Vit D). | Risk of Vitamin A toxicity at high doses; often lower DHA/EPA concentration than purified fish oil. | Supporting bone health and immunity, particularly in regions with limited sun exposure. | When you specifically need to supplement Vitamins A and D alongside your omega-3 intake. |
| Flaxseed Oil | Omega-3 Supplement (Plant Source, ALA) | Rich source of alpha-linolenic acid (ALA), a precursor to DHA and EPA. | Inexpensive; vegan-friendly; widely available. | Contains no direct DHA; the body's conversion of ALA to DHA is extremely inefficient and unreliable. | General wellness for those on a plant-based diet who are not specifically targeting high DHA levels. | For a general, low-cost vegan omega-3 source, if raising specific DHA levels is not the primary goal. |
