Omega-3 Supplement Manufacturer for Custom Softgels
Custom and ready-to-launch omega-3 softgels with flexible EPA-to-DHA ratios, manufactured in a GMP-certified, FDA-registered facility. COA on every batch.
Minimum project investment: $10,000. Custom EPA-to-DHA ratios, enteric coating options, and concentrated fish oil available on every omega-3 softgel production run.
Omega-3 Supplement Manufacturer Built for Brand Owners
Finding a reliable omega-3 supplement manufacturer is difficult because fish oil is one of the most technically demanding raw materials to encapsulate. Oxidation degrades the oil before it reaches the consumer. Poor sourcing leads to rancid product. Generic ratios limit how you position your brand. NutraSeller solves each of these problems at the manufacturing level, before they become customer complaints or negative reviews.
Every omega-3 softgel produced at the facility goes through strict oxidation controls, heavy metal testing, and identity verification using UPLC, HPLC, and FTIR instrumentation. Whether you need a ready-to-launch private label omega-3 formula or a fully custom EPA-to-DHA ratio built from scratch, NutraSeller handles formulation, encapsulation, testing, labeling, and packaging under one production timeline.
This is contract manufacturing omega-3 softgels with production transparency. You receive a COA on every batch, an NDA before any discussion, and direct communication with the team managing your project. No intermediaries. No black-box manufacturing. If you’re launching an omega-3 product on Amazon FBA, Shopify, Walmart, or retail shelves, request a quote for omega-3 manufacturing and get a detailed cost breakdown within days.

Ready-to-launch fish oil softgel formulas with standard EPA/DHA concentrations. Ideal for brands entering the omega-3 market quickly without custom R&D investment. Available with or without enteric coating. Label and packaging design support included.
MOQ: 2,500 UnitsCustom Omega-3 Softgels
Fully custom omega-3 formulations with specific EPA-to-DHA ratios, concentrated fish oil (50-80%), algal oil for vegan positioning, or unique blends with added vitamin D, astaxanthin, or CoQ10. Enteric coating, softgel size selection, and custom bottle counts available. Our R&D team builds the formula to your specifications.
MOQ: ~5,000 UnitsOmega-3 Ingredients for Softgel Manufacturing
The omega-3 category includes multiple source materials and active compounds. NutraSeller sources pharmaceutical-grade and food-grade oils for EPA DHA softgel manufacturing, with concentration levels ranging from standard to highly concentrated forms. Brands can select the source and ratio that aligns with their target consumer and product positioning. Researchers have studied EPA for its potential role in supporting cardiovascular and mood-related functions, while DHA has been studied for its potential role in supporting cognitive function and eye health. All raw materials undergo identity and purity testing before production.
Request a QuoteSolving the Burpback Problem: Enteric Coating and Deodorization Options
Fishy aftertaste and reflux are the number one complaint from consumers who take omega-3 softgels. If you search “fish oil” on any major retail platform, you’ll find thousands of 1-star reviews citing “fish burps,” “rancid taste,” and “horrible aftertaste.” For brands, this isn’t just a customer satisfaction issue. It drives returns, kills repeat purchases, and erodes trust in your product listing.
The root causes are identifiable at the manufacturing level: high oxidation in the raw fish oil, no deodorization of the oil before encapsulation, and standard softgel shells that dissolve in stomach acid, releasing fish oil vapors before reaching the small intestine.
NutraSeller addresses each cause with specific production-level solutions. First, all incoming fish oil is tested for TOTOX (total oxidation value) before it enters the production line. Oil that exceeds acceptable oxidation thresholds is rejected. Second, molecular distillation and deodorization processes are available to remove impurities and reduce odor from the oil itself. Third, enteric-coated softgels are available on both stock and custom omega-3 formulas. The enteric coating is designed to resist stomach acid, allowing the softgel to pass into the small intestine before dissolving. This may help significantly reduce fishy reflux and aftertaste.
For brands that want to go further, natural flavor masking options such as lemon or citrus flavoring can be added to the oil fill. Combined with enteric coating and low-TOTOX sourcing, these manufacturing decisions directly reduce the negative reviews that damage omega-3 product listings. That’s where an experienced fish oil supplement manufacturer adds real value: solving the consumer experience problem before the product ships.
If reducing burpback and improving your customer review profile is a priority, get a custom quote and specify enteric coating during your consultation.
TOTOX Testing on Incoming Oil
Raw fish oil is tested for total oxidation value before encapsulation. High-TOTOX oil is rejected to prevent rancid finished product.
Enteric-Coated Softgels
Acid-resistant coating designed to delay dissolution until the small intestine, which may help reduce fishy reflux and aftertaste.
Natural Lemon and Citrus Options
Added to the oil fill during encapsulation. Combined with enteric coating, this further reduces any remaining fish taste perception.

What Brand Owners Say About NutraSeller
Real production results from brands manufacturing omega-3 softgels with NutraSeller.
We switched to NutraSeller after our previous manufacturer delivered softgels with high oxidation values. The product smelled rancid and customers were furious. NutraSeller sourced low-TOTOX fish oil and provided a COA on every batch. Rancidity complaints disappeared completely, and our customer reorder rate increased within two months.
I needed a 3:1 EPA-to-DHA ratio for a mood support omega-3 softgel targeting Amazon FBA. Every other manufacturer only offered stock ratios. NutraSeller developed the custom formula, handled Amazon-compliant labeling, and delivered finished product on schedule. Launched on Amazon within my projected timeline and sales have been strong since day one.
We were expanding into omega-3 for Walmart shelf placement and needed enteric-coated softgels in a 120-count bottle with retail-ready packaging. Our previous manufacturer required a 25,000-unit MOQ. NutraSeller met the order at a lower MOQ, delivered clean enteric-coated softgels, and we secured retail shelf placement. Professional communication throughout.
Omega-3 Supplement Manufacturer FAQ
Answers to the most common questions brands ask before starting an omega-3 softgel manufacturing project.
What are the MOQs for ordering from an omega-3 supplement manufacturer?
At NutraSeller, the minimum order quantity for stock omega-3 softgel formulas is 2,500 units. For custom omega-3 formulations with specific EPA-to-DHA ratios or enteric coating, the MOQ is approximately 5,000 units. The minimum project investment to begin working with NutraSeller is $10,000, which covers formulation, production, and finished goods. These MOQs are designed to accommodate both new brands testing a single SKU and established brands scaling an existing product line. Request a quote for exact pricing on your order size.
How long does it take an omega-3 supplement manufacturer to produce a first order of softgels?
A first order of stock omega-3 softgels typically takes 12 to 14 weeks from deposit to delivery. Reorders on the same formula are faster, generally 6 to 8 weeks. If you’re requesting a custom formulation, such as a specific EPA-to-DHA ratio, enteric coating, or a unique oil concentration, add 4 to 6 weeks for R&D, stability testing, and prototype approval before production begins. NutraSeller provides a projected timeline during the quoting process so you can plan your launch accordingly.
Can an omega-3 supplement manufacturer customize the EPA-to-DHA ratio in my formula?
Yes. NutraSeller offers full EPA-to-DHA ratio customization during the formulation phase. You can select a high-EPA formula, which some brands position for mood support, a high-DHA formula often positioned for cognitive support, or a balanced ratio for general wellness. Common custom ratios include 3:1 EPA to DHA, 2:1, or equal parts. Our R&D team works with you to determine the right ratio for your target market positioning and then sources the appropriate concentrated fish oil to match. Learn more about choosing between private label and custom formulation.
What testing does an omega-3 supplement manufacturer perform for heavy metals and oxidation levels?
NutraSeller tests incoming fish oil raw materials and finished softgels using UPLC, HPLC, and FTIR instrumentation. Heavy metal testing covers mercury, lead, arsenic, and cadmium, which is a baseline expectation for fish-derived supplements. Oxidation testing includes TOTOX (total oxidation value) analysis on incoming oil to verify freshness before encapsulation. Every batch ships with a Certificate of Analysis. These protocols are especially important for brands selling on Amazon, where third-party testing documentation may be requested.
Does the omega-3 supplement manufacturer offer enteric-coated softgels to reduce fishy aftertaste?
Yes. Enteric-coated omega-3 softgels are one of the most requested options at NutraSeller. The enteric coating is designed to prevent the softgel from dissolving in the stomach, instead releasing in the small intestine. This may help reduce fishy aftertaste and reflux, which is the leading cause of negative consumer reviews for omega-3 products. Enteric coating is available on both stock and custom omega-3 formulas. If this option is important to your brand positioning, mention it during the quoting phase so it can be factored into pricing and lead time.
Can I get a ready-to-launch omega-3 formula or do I need a custom formulation?
NutraSeller offers both options. Stock omega-3 softgel formulas are ready-to-launch with lower MOQs (2,500 units) and faster lead times (12 to 14 weeks for a first order). These are ideal for brands that want to enter the omega-3 market quickly without investing in R&D. Custom formulations are available for brands that need specific EPA-to-DHA ratios, unique oil concentrations, enteric coating, or other modifications. Custom projects start at approximately 5,000 units and include additional R&D time. Explore ready-to-launch private label omega-3 formulas to see available stock options.
What omega-3 source options are available, such as fish oil, algal oil, or krill oil?
The most common omega-3 source for softgel manufacturing is fish oil, available in standard concentration (30% EPA/DHA) or concentrated forms (50% to 80%). Concentrated oils cost more per unit but allow smaller softgel sizes, which can be a strong consumer selling point. Algal oil is available for brands targeting vegan or vegetarian consumers. Algal oil softgels use different encapsulation parameters and may require adjusted production timelines. Discuss your preferred source during the formulation phase so our R&D team can match the right raw material to your product goals.
What is the minimum project investment to start working with an omega-3 supplement manufacturer?
The minimum project investment to begin working with NutraSeller is $10,000. This covers formulation, production, quality testing, and finished goods. The final cost per unit depends on factors including oil type and concentration, softgel size, enteric coating, bottle count, label design, and packaging. Stock formulas at the base MOQ of 2,500 units generally fall at a lower per-unit cost than custom formulations.
