How to Start a Supplement Company in the UK

    Everything you need to know, from choosing your business model to staying compliant with UK food law and advertising rules, in one complete guide.

    1) Pick Your Business Model

    Your model determines everything - cash needs, legal complexity, speed to launch, and margin structure. Pick wisely.

    White Label

    Use a manufacturer's existing formulas under your brand.

    Best for:

    First-time founders, budgets under ~£20k, fast entry, learning the category.

    Upside:

    Quick set-up, low MOQs, simpler QA/claims review.

    Challenges:

    Me-too products, price pressure, limited control of formula/sourcing.

    Beginner tip: Nail positioning, packaging, and reviews before dreaming about "unique blends."

    Custom Formulation

    Design unique ingredients/dosages and own the profile.

    Best for:

    Experienced operators with capital (£50k+), clear gap analysis.

    Upside:

    Moat via IP/differentiation, control of quality and supply.

    Challenges:

    6–18 month timelines, heavier stability/testing, stricter claims substantiation.

    Warning: Don't start here without demand proof and cash. Development + stability + MOQs can swallow £50–£100k before first sale.

    Hybrid

    Start with white label to validate, then layer in custom SKUs.

    Best for:

    Risk-aware builders who want traction, data, and audience before heavy R&D.

    Watch-outs:

    Mixed ops (different lead times/specs), message consistency, phasing.

    Founder tip: Don't move to custom until repeat purchase, CAC/LTV, and genuine review signals say "go."

    2) Do Your Market Research

    Build evidence before inventory. Treat this like an experiment, not a hunch.

    Market Sizing (work from the outside in)
    • Total categorysub-categorymicro-niche (e.g., "women's performance probiotics")
    • Growth/seasonality: e.g., UK public health guidance suggests many adults consider 10 µg vitamin D daily Oct–Mar, so plan winter promos accordingly

    Rule: If you can't cite it, don't state it as fact. Use reputable sources (gov.uk, NHS, trade data).

    Persona Deep Dive
    • Demographics & jobs-to-be-done: Why would someone choose your product over the top 3 incumbents?
    • Buying behaviour: Where they shop, purchase frequency, price ceiling, trusted endorsements
    • Media habits: Channels, formats, creators they actually watch
    Research Moves That Actually Work

    Amazon Intelligence

    • • Read 1-star reviews (real pain points)
    • • Scan Q&A sections
    • • Track price history
    • • Check "Frequently bought together"

    Social Listening

    • • Reddit subs (e.g., r/SupplementsUK)
    • • FB groups
    • • IG/TikTok hashtags
    • • YouTube comments for language and objections

    Direct Research

    • • 10–20 paid interviews (£20–£50)
    • • Quick surveys (Typeform)
    • Message tests (headline/value prop)
    • Pre-orders/deposits to validate willingness to pay

    3) Write Your Business Plan (that you'll actually use)

    Keep it short. Make decisions for the next 90–180 days and model the money.

    Financial Model (the essentials)
    • Unit economics: COGS (product, packaging, label, inbound freight), marketplace/referral fees (e.g., Amazon UK referral fee often ~15% in Health & Personal Care; Stripe card processing commonly 1.5%–2.5% + 20p), fulfilment, VAT, returns
    • 12-month cash flow: Inventory buys, lead times, ad spend, payment lags (retail 30–90 days)
    • Sensitivity tests: What if CAC is 2× higher? What if you stock-out Q4?
    Validation & Risk
    • Milestones: e.g., 100 pre-orders, 4.5★ avg rating after 50 orders, 20% month-2 repeat rate
    • Plan B: Alt manufacturer, backup freight, "pause spend" rules if CAC blows out

    4) UK Compliance (don't wing this)

    Who does what (Great Britain)

    Food Law & Enforcement

    Food supplements are regulated as foods; enforcement by local authorities with the FSA providing guidance. Register as a food business with your local authority at least 28 days before trading.

    Health & Nutrition Claims

    Use only claims on the Great Britain Nutrition & Health Claims (NHC) Register and meet conditions of use.

    Advertising (ASA/CAP Code)

    Ads must stick to authorised wording (flexing allowed only if meaning doesn't change) and general claims must be accompanied by a specific authorised claim.

    Medicinal Line (MHRA)

    If you imply prevention/treatment/cure of disease, you've crossed into medicine - different rules entirely.

    Health Claims: Safe vs. Unsafe

    Allowed Examples

    When conditions are met and the nutrient is named:

    • • "Vitamin D contributes to the normal function of the immune system"
    • • "Calcium is needed for the maintenance of normal bones"
    • • "Iron contributes to the reduction of tiredness and fatigue"
    • • "Magnesium contributes to normal energy-yielding metabolism"

    Use authorised phrasing or a faithful flex; don't exaggerate "normal" into "improves/increases."

    Not Permitted for Foods

    Including supplements:

    • • "Treats depression," "prevents heart disease," "cures diabetes"
    • • Blanket "boosts immunity" claims without the specific authorised claim clearly alongside it
    Labelling Essentials for Food Supplements (GB)

    On-pack must include:

    • • The prescribed name "Food supplement"
    • Recommended daily portion and "Do not exceed" the stated dose
    • • Statement that supplements are not a substitute for a varied diet
    • "Keep out of the reach of young children"
    • Quantity of each nutrient/substance with physiological effect and % NRV per portion (where relevant)
    • Ingredients list with allergens emphasised; lot/batch, best before, storage, directions
    • Name & address of the Food Business Operator - from 1 Jan 2024 GB products must give a UK address consumers can contact
    Novel Foods (common tripwire)

    If an ingredient wasn't consumed significantly before 15 May 1997, it's likely novel and needs FSA authorisation before sale. CBD products remain novel and require authorisation to be lawfully marketed.

    Food Business Registration, HACCP & Traceability
    • Register with your local authority 28 days before trading
    • • Maintain a food safety management system based on HACCP principles (SFBB or MyHACCP tools can help SMEs)
    • • Keep traceability "one step back, one step forward" and have a documented withdrawal/recall plan

    5) Choose a Manufacturer (what "good" looks like)

    Quality & Compliance
    • Certification: BRCGS Food Safety Issue 9 or another GFSI-recognised scheme
    • HACCP: Documented and audited; robust allergen controls; change-control procedures
    • Testing: Clear specifications and Certificates of Analysis (CoAs). For critical assays and contaminants, prefer UKAS (ISO/IEC 17025)-accredited labs
    Operational Due Diligence (questions to ask)
    • • Lead times by format (capsules/powders/gummies), MOQs, capacity buffer, stability data
    • • Label/claims regulatory sign-off workflow
    • • Batch retention, traceability, recall simulation cadence
    • • Will they host audits/visits? What are out-of-spec procedures?

    6) Budget Your Startup Costs (plan for reality)

    Cash flow - not competitors - kills most launches. Treat ranges below as planning baselines; validate yours.

    Bootstrap (£25k–£50k)
    • • 1–3 white-label SKUs
    • • Simple brand & site
    • • Modest paid media
    • • 3–6 months stock
    • • Basic legal/label checks
    Professional (£50k–£100k)
    • • 2–4 custom/complex SKUs
    • • Stronger creative
    • • Full claims/label legal review
    • • 6–12 months stock
    • • Performance marketing
    Premium (£100k+)
    • • Wider custom range
    • • Premium packaging
    • • Larger media
    • • 12+ months stock on A-lines
    • • Deeper R&D and testing
    Line Items People Forget
    • Label legal review: ~£500–£2,000 per range
    • Nutritional analysis & micro testing: ~£200–£500 per product
    • Product liability insurance: from ~£100–£300/month
    • GS1 barcodes: starter plans from £50/yr ex-VAT for micro-turnover, rising with scale
    • Trade mark: £170 online for 1 class (+£50 per extra)
    • Companies House fees: digital incorporation £50; confirmation statement £34

    7) Build a Brand That Stands Out

    Brand Fundamentals
    • Story: Why you exist, the specific problem, credibility proof, what's different
    • Identity: Professional logo & palette, consistent packs, trust-building site, social templates
    • Positioning: Who you serve + what outcome you enable (with evidence)
    • Messaging: 15-second value prop, benefit hierarchy, proof points, clear CTAs
    Differentiation Angles (that actually move the needle)
    • • Superior sourcing & transparent specs (publish CoA snapshots)
    • • Third-party testing (highlight UKAS-accredited labs)
    • • Audience specificity (e.g., "perimenopause runners")
    • • Formulation strategy (dose forms, bioavailability, taste)

    8) Craft Your Go-to-Market Strategy

    D2C First

    Higher margins (40–60%), direct data, but demands strong creative and media execution.

    Retail Next

    Credibility and reach; lower margins (20–35%), buyer timelines, must show velocity.

    Hybrid

    Launch D2C → build proof (LTV, reviews, velocity) → pitch retail → expand.

    Year-1 Marketing Budget Reality

    Expect 25–40% of revenue into customer acquisition in early months. CAC usually starts painful and improves with creative/message/product-market fit.

    CAC Sanity Checks

    • • Early-stage CAC: £20–£50+ per customer isn't unusual for paid social/search while you learn
    • • Allocate £1k–£5k to structured testing before expecting efficiency

    Channels & Tactics (mix to test)

    • Paid: Google (search & shopping), Meta/IG, YouTube
    • Owned: Email/SMS automations, SEO content answering specific buyer jobs
    • Influence/PR: Credible creators, podcasts, expert features (claims-safe scripts!)
    • Partnerships: Gyms, health stores, affiliates, practitioner programmes

    9) Launch, Learn, and Scale

    Phase 1: Soft Launch (Weeks 1–8)

    Goals: 50–100 customers; tight feedback loops.

    Do: Price & message A/B tests, ops rehearsal, <24h CS replies, build review base.

    Signals: 4.5★+ rating, positive contribution margin, ≥15% repeat by day-45 cohort.

    Phase 2: Scale (Months 3–12)
    • • Double down on proven channels/creatives
    • • Referral & loyalty live
    • • Add SKUs from feedback
    • • Track CAC/LTV by cohort and device (stop averaging)
    Phase 3: Optimise (Year 2+)
    • • Product innovation cadence (new formats/flavours informed by retention data)
    • • Market expansion (EU requires separate compliance), subscriptions, B2B
    • • Supply-chain automation, QA maturity, cost renegotiations
