Cod Liver Oil Contract Manufacturing, Softgels and Liquid

Cod liver oil is not the same product as standard fish oil. It is pressed from the livers of Atlantic cod, so it delivers omega-3 EPA and DHA and also naturally occurring vitamin A and vitamin D in the same oil. ZOOMSHEAL Health runs a dedicated oily-liquid and softgel line in our GMP-certified Guangzhou Huadu facility, where we control oil intake, blending, encapsulation and filling so every bottle matches the specification you approved.

Because vitamin A and vitamin D are declared nutrients on a cod liver oil label, we calculate the vitamin A and vitamin D content against the regulations of your destination market and adjust serving size or dilution accordingly. Clients include private label supplement brands, pharmacy ranges, sports and family nutrition sellers, and DTC brands exporting to the US, EU, UK and Middle East.

What Sets Our Cod Liver Oil Production Apart

Atlantic Cod Liver Sourcing
Our cod liver oil is sourced from qualified Atlantic cod (Gadus morhua) suppliers and arrives with certificates of analysis covering origin, free fatty acid, peroxide value and anisidine value. Every batch is assayed for omega-3 EPA and DHA content and for vitamin A and vitamin D before blending.
Softgel, Liquid and Dropper Formats
We fill 500 mg to 2,000 mg cod liver oil softgels, 30 mL to 120 mL dropper bottles and 100 mL to 500 mL screw-cap liquid bottles on the same line. From small 60-count bottles to larger family packs, each format keeps its own fill weight and overage strategy.
Flavour Masking for Liquid and Softgels
Cod liver oil has a strong natural taste, so we offer lemon, orange and mint flavour systems to mask it in liquid and bite-down formats. Flavour, sweetener and acidity are tuned during pilot so the finished product stays palatable and stable through shelf life.
Vitamin A & D Compliance Work
We screen each proposed formula for total vitamin A and vitamin D per daily dose and flag any overlap, so the label claim fits the vitamin upper limits of your market. Water-miscible dilutions let us fine-tune the declared vitamin A and D levels without altering the oil base.

Our Cod Liver Oil Contract Manufacturing Process

01
Consultation & Brief
We review your dosage form, oil dosage, vitamin A and vitamin D target and destination market, then recommend a formula and format that is feasible and cost-effective for your volume.
02
Formula & Pilot Sample
Our team sets the oil base, flavour, carrier and overage, then produces a pilot batch so you can check taste, texture and softgel or bottle appearance before approval.
03
Quotation & Approval
When the pilot is approved we fix the finished specification, agree MOQ, bottle format and lead time, and issue the formal quotation and proforma invoice.
04
Encapsulation & Liquid Filling
Cod liver oil is blended and delivered to softgel encapsulation or liquid filling on dedicated oily-product lines, with in-process fill-weight and seal checks throughout the run.
05
Quality Control & Testing
Every batch is tested for omega-3 EPA and DHA, vitamin A and vitamin D, peroxide value, fill uniformity and microbiology, and is released only once the certificate of analysis is approved.
06
Packaging & Export Shipping
Softgels and liquids are bottled, induction-sealed, labelled to your artwork and cartoned, and the shipment is documented for air, sea or express delivery to your market.

Quality Control for Cod Liver Oil

Cod liver oil carries both omega-3 and the fat-soluble vitamins A and D in one oil, so our quality programme covers oxidation, potency and declared vitamins together. Every incoming oil is checked for free fatty acid, peroxide value, anisidine value and vitamin A and vitamin D content, and each finished batch is tested for fill uniformity, leak and seal integrity and microbial safety.

The plant is GMP-certified in Guangzhou Huadu and complies with FDA, NSF and cGMP standards, with HACCP controls spanning oil intake, blending, encapsulation, liquid filling and packing. Stability work, accelerated and real-time, supports both the shelf life and the vitamin and omega-3 claims printed on your finished bottle.

Cod Liver Oil Manufacturing FAQ

What is the minimum order quantity for custom cod liver oil?+
Softgel and liquid projects typically start at 10,000 bottles, while bulk winterized cod liver oil starts at 25 kg. A first small-batch trial is negotiable if you are validating a new cod liver oil SKU. Tell us your dosage form and volume and we will confirm the exact minimum.
Can you manufacture cod liver oil under my own brand?+
Yes. We are a private label and OEM/ODM manufacturer, so your brand appears on the label, carton and certificate of analysis while we supply the oil, dosage form and packaging. The finished goods and the trademark remain yours.
How is cod liver oil different from fish oil omega-3?+
Standard fish oil omega-3 is pressed from fish bodies and usually carries only EPA and DHA. Cod liver oil is specifically extracted from Atlantic cod livers, so the same oil naturally contains omega-3 EPA and DHA plus vitamin A and vitamin D. We manufacture the liver-oil version, not a plain fish-body omega-3.
How do you handle the natural vitamin A and vitamin D?+
Because vitamin A and D are declared nutrients, we calculate the total vitamin A and vitamin D per daily dose against the upper limits of your destination market and adjust serving size or dilute with carrier oil where needed. This keeps your label compliant without changing the cod liver oil base.
How long does cod liver oil production take?+
Figure on 5 to 6 weeks from formula and artwork sign-off for softgels or liquid, and 3 to 5 weeks for bulk oil. Oil sourcing, blending, encapsulation, release testing and export packing all sit inside that window, and locked repeats run noticeably quicker.
Do you provide packaging and label design?+
We stock softgel bottles, dropper bottles, liquid bottles, cartons and droppers for cod liver oil lines and can either create your label artwork or print from supplied files. Dielines, barcodes and compliant supplement wording are prepared so the product lands retail-ready.
Can you help with shipping and customs documents?+
Exports of cod liver oil travel with a commercial invoice, packing list, certificate of analysis, certificate of origin and any health certificates the destination requires. We arrange air, sea or express carriage and can cooperate with a nominated forwarder or suggest one.
What payment terms do you offer?+
New cod liver oil orders normally open with a 30% deposit and close with the 70% balance settled before dispatch, by T/T or another method we agree. Repeat buyers are welcome to request terms, and prices are quoted in USD unless you specify otherwise.
