What We  Offer

CJK Sourcing+ supports supplement brands across the full build journey — from early-stage validation through to launch-ready execution.

Some clients engage us for focused support in one area. Others work with us across multiple stages. We scope every engagement based on where you are and what will create the most value.

Market Research & Product Strategy

Before formulation or sourcing begins, we help founders understand what to build and why. This can include:
  • Market and competitor analysis
  • Format and positioning recommendations
  • Pricing and margin feasibility checks
  • Identifying gaps and realistic differentiation

Supplement Formulation

We support formulation across human and pet supplements, with a strong focus on efficacy, compliance, and commercial viability. This includes:
  • Ingredient selection and dosing rationale
  • Compliance-aware formulation (UK, EU, US)
  • Cost-conscious formulation decisions
  • Iteration based on stability, format, and sourcing constraints

Supplier Sourcing & Manufacturing

Our core value lies in our established supplier network across the UK, EU, and US — built through 150+ sourcing projects and long-term manufacturing relationships.
Rather than always starting from scratch, we connect brands with proven, reliable manufacturers already aligned to specific formats, volumes, and regulatory requirements. Support can include:
  • Access to vetted manufacturers by format and market
  • MOQ, pricing, and lead-time negotiation informed by real benchmarks
  • Sample coordination and comparative evaluation
  • Direct supplier communication and production setup
We prioritise fit, reliability, and long-term viability when introducing suppliers, so recommendations are grounded in experience, not guesswork.

Branding, Packaging & Creative Copy

We support the assets required to take a supplement product to market properly, across Amazon, DTC, and TikTok-first channels. This includes:
  • Brand and packaging direction
  • Amazon-ready creatives
  • Label structure and compliant copy
  • TikTok creative direction
  • Claims review and positioning alignment
  • Packaging formats aligned with route to market
Design work is always informed by compliance, platform requirements, and conversion — never aesthetics alone.

Shopify Builds & Launch Infrastructure

For brands launching DTC, we can support the technical foundations required to sell. This can include:
  • Shopify store builds
  • Product detail page structure and copy
  • Launch readiness checks
The focus is functionality, clarity, and conversion — not unnecessary complexity.

Compliance Support

Compliance is considered throughout the build process, not added at the end. We support:ccc
  • Ingredient and claims alignment
  • Label and packaging compliance checks
  • Market-specific considerations (UK, EU, US)
  • Early identification of compliance constraints
This helps prevent relabelling, reformulation, or delayed launches.

How Services Are Scoped

Not every brand needs everything at once.

Some engagements are short, focused sprints. Others are longer-term partnerships. We’ll always recommend the scope that makes sense for your stage — and be clear about what doesn’t.
