Make the formula matter.
Active ingredients at meaningful doses, sourced from suppliers with full traceability. We say no to greenwashed labels and pixie-dust formulations — even when it is faster to say yes.
About
Engineered for brands that mean it.
YANG&CO. was founded on the belief that supplement brands deserve a manufacturer that obsesses over the formula, the finish, and the schedule — not just the spreadsheet. We make supplements the way thoughtful brand owners would, if they ran the floor themselves.
The principles
Four standards we will not compromise on.
Hold the schedule.
Launch dates do not slip on our floor. Production planning, packaging procurement, and QA cadence are coordinated as a single schedule, not five vendor handoffs.
Document everything.
Master batch records, CoAs, stability data, allergen testing — all retained, indexed, and shareable on request. The same discipline that satisfies an FDA audit satisfies a thoughtful brand owner.
Stay one team.
Formulation, manufacturing, packaging, fulfillment — all of it under one roof, accountable to one project lead. No finger-pointing, no missed weeks waiting on the next vendor in the chain.

Quality
Tested, signed, and traceable.
Every batch ships with a Certificate of Analysis. Identity, allergen, and microbial testing are routine; stability programs are run on production batches, not just R&D samples. Documentation is retained for the full statutory window and shared with brand owners on request.
