Who We Work With

We work best with founders and teams who:
Are building or expanding a supplement brand
We work with both new founders launching their first product and established supplement brands looking to scale, optimise, or improve their supply chain.
Care about commercial reality, not just ingredients
Many supplement manufacturers will talk endlessly about ingredients, trends, and buzzwords. Because a great formula means nothing if you can’t produce it reliably or sell it profitably.
Want fewer surprises and better decisions
Launching supplements comes with hundreds of decisions, from formulation and MOQs to packaging, testing, and logistics. We help you see the full picture before you commit, so you avoid costly mistakes and delays. The goal is simple: clear information, better decisions, and smoother launches.
Value straight answers over sales talk
This industry is full of overpromises and vague answers. We believe in direct, practical guidance, even when the answer isn’t what you hoped to hear. If something won’t work commercially, we’ll tell you. If it will, we’ll help you build it properly.
We help you choose the right format for the product and the market, not just what’s trending or easiest to producet

Why CJK Sourcing+

CJK Sourcing+ was built by operators who have launched and scaled real brands across Amazon, DTC, and international markets.

We’ve dealt with reformulations, supplier issues, compliance friction, and costly mistakes, and we built this business to help others avoid them.
