A formulation-led contract manufacturer
SIYI Biotech builds supplement programmes for brands, distributors and cross-border sellers — with formulation, production and packing in one process.
How we work
We start from the specification, not the catalogue. A project begins with the dosage form, the market and the serving design, and every later decision — ingredients, tooling, packing — follows that sheet.
The same team follows a project from bench sample to packed goods, so changes do not get lost between departments. Buyers keep one contact for formulation, quality and shipping questions.
Capability build-out
Each capability was added to keep one project inside one process rather than handing it between suppliers.
- 01
Formulation and bench sampling for gummies, capsules and tablets.
- 02
Softgel encapsulation with vegan and enteric shell options.
- 03
Oral liquid filling and single-serve sachet lines.
- 04
Pet nutrition and special dietary formats with dedicated label review.
