Fish Oil & Omega-3 Manufacturers in the UK

Start with the USA list, check the exact facility and its certificate scope, and confirm private label fish oil and omega-3 products. Ask for the minimum order, first-run and reorder lead times, testing plan and an itemized quote. Website capabilities are company claims unless a separate registry basis is shown; confirm the proposed work directly.

Ask which oil sources they use (fish, krill or algae), how they test for oxidation, for example peroxide and anisidine values, how they test for contaminants, and which formats they make, such as softgels or liquids. Ask whether they make softgels in-house or through a partner.

No. A company is listed here when one of its facilities is on a public registry we check and either its USDA Organic certificate lists omega-3 items or its own website says it makes omega-3 or fish oil products. The USDA Organic item list is the certifier’s record of what the operation is certified to handle organically, as we found it in the USDA Organic Integrity Database on the date shown; it covers organic items only and is not a test of any product. A website claim is the company’s own statement: we keep the quote, the page and the date we checked. Each card says which applies. Confirm either with the manufacturer before you rely on it.

Ask for minimum order quantity, lead times, formulation options, testing and certificates of analysis, in writing. In detail: ask about minimum order quantity (MOQ) per SKU, lead time for a first run and for reorders, whether they offer stock formulas or custom formulation, who sources raw materials, what testing they run (identity, potency, microbiological, heavy metals) and whether you receive a certificate of analysis (COA) per batch, and whether they support the label claims you plan to make. Terms vary widely by manufacturer, so compare written answers rather than assumptions.

Ask the manufacturer for their current certificate and the exact facility address it covers, then look that facility up on the certifier’s public listing (for NSF/ANSI 455, NSF’s online listings). Certificates apply to specific sites, so make sure the facility that will make your product is the one listed. Each profile here links to the public listing we checked and the date we checked it.
