Liquid Supplement Contract Manufacturer — Oral Drops
Oral drops deliver concentrated liquid formulas in dropper bottles — precise dosing, fast product development and strong appeal in vitamin D, herbal and specialty segments. YUKANG, the brand of Yukang Medicine (Guangzhou) Co., Ltd., manufactures oral-drop supplements on dedicated liquid lines in its 10,000 m² cGMP facility in Guangzhou.
Oral Drop Manufacturing Capability
The liquid operation covers compounding, homogenization, filtration and aseptic-style filling into dropper bottles across standard sizes. Dropper assemblies are matched to the formula's viscosity so each drop dispenses consistently. As part of the facility's ten fully automatic lines, liquid production runs under the cGMP quality system (21 CFR Part 111), with raw-material verification and finished-product testing — including microbial testing appropriate to liquid products — on every batch.
Process Points That Matter
- Homogeneity — compounding and mixing procedures keep actives evenly distributed through the liquid, so the first dose matches the last.
- Microbial control — water quality, equipment sanitation and finished-product microbial testing are managed to liquid-product standards.
- Fill accuracy — volumetric filling checks hold each bottle to its declared volume.
- Closure integrity — dropper assemblies and caps are torque-checked so bottles arrive sealed and leak-free.
What You Can Customize
- Formula — your own liquid formula (OEM), a ready-made YJN/RT profile (private label), or a custom development by the 30+ formulators from the company's self-described 10,000+ formula library (ODM/turnkey).
- Specifications — bottle size, dropper type, flavor and sweetness system, carrier base, and active-ingredient concentration per drop or per serving.
- Packaging — dropper bottles in multiple sizes, cartoned or uncartoned; your labeling with FDA compliance review for the US market; Amazon FBA preparation available.
Compliance
The facility operates under cGMP (21 CFR Part 111) and holds FDA food facility registration (a facility registration, not a product certification), ISO 22000 and HACCP; the group's Wuxi site is BRCGS-audited at grade A. Certificates are available upon request.
