Let's be honest about something: the UK health supplements market is booming, and a significant portion of the products on pharmacy shelves, gym bags, and Instagram feeds are manufactured in China. Yet the guidance available to UK business owners thinking about entering this space is, frankly, a mess — scattered across MHRA PDFs, FSA guidance notes, and forum posts from 2019.
This guide exists to change that. Whether you want to launch a private label protein powder, source third-party tested omega-3 capsules, or build a full nutraceutical brand sourced from Asia, you need to understand both the manufacturing landscape and the UK compliance minefield before you place a single order.
This guide is for: UK brand owners and entrepreneurs looking to launch or scale a health supplement business; Amazon sellers exploring private label supplements from China; wellness brands wanting to understand MHRA and FSA Novel Foods requirements; and importers who've heard the margins are good but aren't sure where to start.
At Epic Sourcing, we've worked with UK health and wellness brands sourcing supplements, nutraceuticals, and health products from China and Vietnam. We know which manufacturers are worth your time, which compliance traps catch out new importers every single year, and how to build a sourcing strategy that actually holds up to scrutiny. This is the guide we wish existed when our first clients came to us with a supplement idea.
A nutraceutical is any product derived from food sources that provides health benefits beyond basic nutrition — including vitamins, minerals, herbal extracts, probiotics, and functional food ingredients. In UK regulatory terms, "food supplements" are the specific legal category governed by the Food Supplements (England) Regulations 2003, though the broader nutraceutical space also intersects with MHRA-regulated borderline medicines.
The UK health supplements market is worth over £500 million annually, and it's growing year on year. Post-pandemic shifts in consumer behaviour — a lasting emphasis on immunity, gut health, sleep, and performance — have driven consistent demand across every demographic. More importantly for brand owners, it's a category where consumers actively seek new brands, private labels carry credibility, and margins remain healthy compared to commoditised general retail.
For UK entrepreneurs and brand builders, the economics are compelling. A well-positioned supplement brand can achieve retail prices of £20–£60 per SKU on products that cost £2–£8 to manufacture in China. Amazon UK, TikTok Shop, and Shopify DTC are all active channels where supplement brands regularly achieve six-figure revenues within their first two years. The challenge isn't the market — it's navigating the supply chain and compliance correctly from day one.
China dominates global supplement manufacturing. The Yangtze River Delta region — particularly Hangzhou, Ningbo, and Shanghai — is home to hundreds of GMP-certified contract manufacturers offering everything from bespoke formulations to white-label stock lines. Capsules, tablets, powders, softgels, effervescent tablets, gummies — virtually every delivery format is available at competitive prices, with increasingly sophisticated packaging and branding capabilities.
Vietnam is also emerging as a credible supplement manufacturing hub, particularly for herbal extracts, organic ingredients, and plant-based formulations. For UK businesses importing from Vietnam, the UK-Vietnam Free Trade Agreement (UKVFTA) eliminates or reduces tariffs on many health food and supplement-adjacent categories — a genuine cost advantage we'll cover in the compliance section.
The UK is Europe's second-largest dietary supplement market. Vitamins and minerals account for the largest share, followed by sports nutrition and herbal/botanical products. Demand for beauty-from-within supplements (collagen, hyaluronic acid, biotin) and functional mushroom products (lion's mane, reishi) is growing particularly fast.
Not every business is equally positioned to succeed with supplements. The category works especially well for:
Where the opportunity is harder: businesses without any brand positioning, budget below £15,000–£20,000 for a proper launch (compliant labelling, third-party testing, minimum stock), or those expecting to compete purely on price against established supplement brands. The UK market rewards positioning and compliance — not cheapness.
Understanding where your supplements come from — and the differences between manufacturing in China and Vietnam — shapes everything from your cost base to your regulatory exposure.
China produces the majority of the world's raw supplement ingredients, and the manufacturing infrastructure reflects this. The key supplement manufacturing clusters in China are:
Chinese manufacturers range from large ISO 9001 / GMP-certified facilities that serve global brands (including many UK high-street names) to small trading companies that simply rebadge imported raw materials. The quality gap is enormous. Vetting manufacturers properly is the single most important step in your sourcing process.
Vietnam's supplement manufacturing industry is smaller than China's but growing rapidly. Vietnam excels in herbal and botanical extracts, organic and natural certifications, plant-based and clean-label formulations, and offers a lower cost base for hand-intensive manufacturing steps.
The critical commercial advantage for UK importers is the UKVFTA. Under the UK-Vietnam Free Trade Agreement, many food supplement and health product categories qualify for reduced or zero import tariffs when importing from Vietnam. A comparable product from China might attract 3–6.5% import duty; the same or equivalent product from a certified Vietnamese supplier could come in at 0%.
| Factor | China | Vietnam |
|---|---|---|
| Manufacturing range | Extremely broad — all formats, all categories | Strong in herbals; growing in others |
| GMP certification | Widespread; many EU GMP and FDA-registered plants | Growing; fewer EU GMP options but increasing |
| Minimum order quantities | 1,000–5,000 units typical | 500–3,000 units; flexible for small runs |
| UK import duty (typical) | 0–6.5% depending on HS code | 0–3% under UKVFTA |
| Sea freight to UK | ~25–35 days (Felixstowe/Southampton) | ~28–35 days (Felixstowe/Southampton) |
| Private label capability | Excellent; high design and packaging sophistication | Good; growing rapidly for EU/UK market |
| Best for | Most supplement categories, scale | Herbal, organic, clean-label; UKVFTA savings |
This is the section most supplement entrepreneurs skip when they're excited about the market opportunity. It's also the section that determines whether your business gets to launch at all, gets your products seized at the border, or finds itself receiving an enforcement notice a year into trading.
Post-Brexit, UK supplement regulations are now diverging from EU rules. The EU's Novel Food catalogue, CE marking, and EFSA authorisation processes do not automatically apply in Great Britain. You must check against UK-specific legislation: the Food Supplements (England) Regulations 2003, the UK Novel Foods Register, and MHRA guidance. A product compliant in Germany or France may still require additional authorisation to sell in Great Britain.
The Medicines and Healthcare products Regulatory Agency (MHRA) has jurisdiction over products that make medicinal claims or contain ingredients that could be classified as medicines. If your product makes a claim that it treats, prevents, or cures a disease or medical condition, MHRA will likely consider it a borderline medicine — requiring a Marketing Authorisation to sell in the UK.
Common MHRA trigger points: products containing CBD above certain concentrations; sleep products containing melatonin (a POM in the UK); products making specific immunological claims; high-dose herbal extracts (valerian, kava, adaptogens at therapeutic doses); and any product claiming to manage blood glucose, cholesterol, or blood pressure.
A Novel Food is any food or ingredient not in significant use in Great Britain before 15 May 1997. Categories commonly requiring Novel Foods authorisation include: CBD (cannabidiol); functional mushroom extracts (lion's mane, chaga, turkey tail in extracted form); NMN (nicotinamide mononucleotide); astaxanthin above certain concentrations; certain probiotic strains; insect-derived proteins; and collagen hydrolysates from certain sources.
UK port authorities and Trading Standards actively seize supplement shipments containing Novel Foods ingredients that lack authorisation. Your entire container can be held at Felixstowe or Southampton whilst compliance is assessed.
The Food Supplements (England) Regulations 2003 specify which vitamins and minerals are permitted in UK food supplements, and from which chemical forms. Some Chinese manufacturers use synthetic forms of nutrients permitted in China or the EU but not on the UK permitted sources list. Always cross-check your formula against Schedule 1 and Schedule 2 before approving a specification.
All food supplements sold in Great Britain must carry: the designation "food supplement"; the names of characterising substances; recommended daily portion; a warning not to exceed the daily dose; a statement that supplements should not substitute a varied diet; a warning to keep out of reach of young children; net quantity; best before date; storage conditions; and the name and address of the UK-established manufacturer or seller.
Only UK-authorised nutrition and health claims (listed in the Great Britain Nutrition and Health Claims register maintained by the FSA) may be made on supplement labels and marketing materials. EU-authorised claims do not automatically apply in Great Britain after Brexit. Making an unauthorised health claim is a criminal offence under UK food law.
| Product Category | HS Code | UK Tariff (China) | UK Tariff (Vietnam/UKVFTA) |
|---|---|---|---|
| Vitamins (bulk) | 2936 | 0–6.5% | 0% (UKVFTA) |
| Protein powders | 2106.10 | 0% | 0% |
| Amino acids | 2922 | 0–3.7% | 0% (UKVFTA) |
| Herbal/botanical extracts | 1302 | 0–3% | 0% (UKVFTA) |
| Fish oil / omega-3 softgels | 1504.20 | 0% | 0% |
| Prepared food supplements (capsules/tablets) | 2106.90 | 0–6.5% | 0–2% (UKVFTA) |
| Gummy supplements | 1704.90/2106.90 | 4.5–10.9% | 0–4% (UKVFTA) |
All imports also attract VAT at 20% (calculated on customs value + duty). Most food supplements are zero-rated for VAT on domestic sale in the UK, but you still pay import VAT at the border — reclaimed via your VAT return. You'll need an EORI number from HMRC and will file declarations through the Customs Declaration Service (CDS).
This is where most UK supplement brand owners make their costliest mistakes. The internet is full of advice that boils down to "search Alibaba and ask for GMP certificates." That approach produces unreliable results at best and counterfeit ingredients at worst.
One of the most important due diligence steps is requesting Certificates of Analysis not just for the finished product, but for each raw ingredient. Identity fraud — substituting a cheaper ingredient for a stated one — is a documented issue in the supplement supply chain.
OEM means you provide the formula; the manufacturer produces it to your exact requirements. This gives full control but requires a ready formula and higher MOQs. ODM means you rebrand the manufacturer's pre-developed stock formula — lower MOQs, faster lead times, but your formula is not exclusive. For new brands, ODM is often the right starting point.
| Product Format | Typical MOQ | Ex-Works Unit Cost (indicative) | Lead Time (first order) |
|---|---|---|---|
| Capsules (stock formula, ODM) | 500–1,000 units | £0.80–£2.50 / 60-cap bottle | 30–45 days |
| Capsules (custom OEM formula) | 3,000–5,000 units | £1.50–£5.00 / 60-cap bottle | 45–75 days (incl. stability) |
| Powder sachets (protein/greens) | 500–1,000 kg | £3–£12 / kg (formula-dependent) | 30–60 days |
| Softgel capsules (fish oil, CoQ10) | 5,000–10,000 units | £1.20–£4.00 / 60-cap bottle | 45–60 days |
| Gummies | 3,000–5,000 units | £2.50–£6.00 / 60-gummy bottle | 45–75 days |
| Liquid tinctures/drops | 1,000–2,000 units | £1.50–£5.00 / 30ml bottle | 30–50 days |
| Tablets (pressed) | 5,000–10,000 units | £0.60–£2.00 / 60-tab bottle | 45–60 days |
Quality control for supplements sourced from China is not optional — it's a commercial and legal necessity. Unlike most consumer goods, supplements are ingested. Contamination, mislabelling, or incorrect dosing has direct health implications and significant liability implications for your business.
1. Pre-production raw material testing. Before manufacturing begins, key active ingredients should be identity-tested by an accredited laboratory. For botanical extracts especially, HPLC identity and potency testing is standard.
2. In-process quality monitoring. Request records of in-process quality checks — fill weights (capsules), blend uniformity (powders), hardness testing (tablets).
3. Pre-shipment finished product testing. Before goods leave China, test each batch for: identity of active ingredients; potency/label claim verification; microbial contamination; heavy metals (lead, mercury, arsenic, cadmium); and absence of undeclared substances.
4. UK port-of-entry checks. HMRC and APHA conduct food supplement checks at UK ports. Having pre-shipment test results available means you can resolve queries quickly.
For maximum credibility with UK retailers and regulators, use a UKAS-accredited laboratory for finished product testing. Major UK supplement brands use LGC, Eurofins UK, or Fera Science for regulatory-grade testing. In China, Eurofins and SGS are present in key manufacturing regions.
For brands planning meaningful volume, a physical factory audit before placing significant orders is worth the investment. Epic Sourcing can arrange qualified third-party factory audits in China — including pre-audit questionnaire review, on-site inspection, and a written audit report.
All customs declarations are filed through the Customs Declaration Service (CDS). Most importers use a freight forwarder to handle this.
Some supplement raw materials — particularly animal-derived ingredients (gelatin, fish collagen, bone-derived) and certain plant materials — require import notifications or phytosanitary certificates. Always check with APHA if your product contains animal-derived or plant-material ingredients.

Book Your Free ConsultationSourcing health supplements from China or Vietnam for the UK market is genuinely complicated. The manufacturer landscape is huge and uneven in quality; the compliance requirements are more demanding than almost any other consumer goods category; and the quality control process requires more rigour than, say, sourcing homewares.

Supplement sourcing is one of the areas where having an experienced team in your corner makes a material difference. Our team travels to China and Vietnam regularly, maintains relationships with supplement manufacturers we've vetted over multiple client orders, and understands the UK compliance context that shapes every sourcing decision.
Yes. If you're manufacturing, processing, distributing, or selling food — including food supplements — as a business in the UK, you must register your food business with your local authority at least 28 days before you start trading. This is required under EU Regulation 852/2004 as retained in UK law. Registration is free and done online through your local council.
Registration does not mean your products are approved — it puts you on the local authority's radar for food hygiene inspections. You remain responsible for ensuring compliance with the Food Supplements (England) Regulations 2003, Novel Foods regulations, and labelling requirements.
If your products might be considered borderline medicines, engage with MHRA before food business registration becomes your primary concern.
Some larger Chinese supplement contract manufacturers have label templates incorporating UK legal requirements. However, never rely on a manufacturer's template without independent review — the most common errors are unauthorised health claims (copied from US-market products), incorrect vitamin or mineral source declarations, and missing required UK labelling text.
All label copy should be reviewed by a UK food law specialist before printing — typically £300–£600 per SKU. UK supplement brands have faced Trading Standards enforcement notices for non-compliant labelling; the reputational and financial damage far outweighs the review cost.
We'd also recommend building your own label design from scratch. A private label brand using an obviously generic label loses the premium positioning that justifies the margin.
Two conditions must be met. First, your product must fall within a tariff line covered by UKVFTA preferential rates — check the UK Global Tariff schedule with UKVFTA annotations on gov.uk. Second, your product must meet the Rules of Origin requirements, typically meaning it must be sufficiently manufactured in Vietnam.
A supplement fully manufactured in Vietnam from Vietnamese-origin or substantially processed ingredients should qualify. A product where all raw materials are imported from China and simply packaged in Vietnam is unlikely to meet the Rules of Origin threshold.
To claim the preference, your Vietnamese supplier must provide a valid Certificate of Origin (EUR.1 or origin declaration). Your customs broker includes the preference claim in the CDS declaration.
For premium health-focused DTC brands and independent health retailers, Informed Sport or Informed Sport — Batch Tested certification carries significant weight — demonstrating that each batch has been tested for WADA-prohibited substances, valued by both athletes and health-conscious consumers.
For the vegan market, Vegan Society certification or the V-label are recognised in the UK. For organic ingredients, Soil Association certification is the gold standard. For Holland & Barrett or independent health stores, GMP manufacturing evidence and batch testing certificates are increasingly expected.
These certifications add cost — Informed Sport batch testing alone runs to several hundred pounds per batch — but support premium pricing and retail placement.
Sourcing agent fees vary by model. Commission-based agents charge 5–10% of order value; flat-fee agents charge a fixed fee per project or month. For supplement sourcing, flat-fee models like Epic Sourcing's packages (from £699) often make more sense — commission agents have a structural incentive to steer you towards higher-value orders or more expensive manufacturers.
The value of a specialist sourcing agent goes well beyond admin savings. The ability to identify manufacturers who've successfully supplied UK brands, knowledge of which certification claims are genuine versus paper-only, and QC oversight during production are worth multiples of the agent fee in avoided mistakes.
For supplement sourcing especially, the compliance knowledge embedded in a good sourcing agent is the most valuable part of the service — not just finding a factory, but finding the right one.
Whether you're starting from a formula concept or ready to place your first production order, Epic Sourcing's team can guide you through manufacturer selection, compliance review, and quality control — so your first supplement launch goes the way it should.
