CSK Biotech — Professional Antioxidant Supplement Manufacturer & CDMO Solutions

As a customer looking for a reliable antioxidant supplement manufacturer, you want proven expertise, scale, and regulatory compliance. Founded in 2008, CSK Biotech combines 15+ years of industry experience with a GMP-certified 2,000㎡ factory, seven advanced production lines, and annual capacities exceeding 4.5 billion softgels and 1.5 billion tablets. We deliver end-to-end CDMO solutions—R&D, formulation development, pilot testing, stability verification, production, regulatory support, and free packaging—so brands can launch fast with predictable quality. Our certifications (GMPC, FDA, HACCP, ISO) and global client track record ensure we meet strict safety and quality standards, making us an ideal partner for brands seeking a seasoned antioxidant supplement manufacturer.

We manufacture antioxidant supplements in multiple formats to suit market needs: softgels, capsules, tablets, powders, gummies, and liquids. Our seven advanced production lines support large-scale runs and flexible batch sizes, while in-house R&D can optimize formulations for bioavailability, taste, stability, and label claims. As a full-service antioxidant supplement manufacturer and CDMO, we also handle pilot-scale runs, stability testing, and packaging. This range lets us support everything from niche private-label launches to high-volume global distributions.

Yes. CSK Biotech offers three cooperation models tailored to client needs: ODM for market-driven product innovation, CDM for bespoke formulation design, and OEM for exact formula production. Our experienced R&D team will translate your concept into a market-ready antioxidant formula, perform pilot tests and stability verification, and scale to full production. We also assist with regulatory registration and marketing support. For custom projects, you can expect collaborative formulation iterations, technical documentation, and manufacturing transfer—all managed under our CDMO framework to reduce risk and speed time-to-market.

Lead times and MOQ vary by product format and customization level. Thanks to our large-scale capacity (4.5 billion softgels and 1.5 billion tablets annually) and seven production lines, we can accommodate both small-batch development runs and high-volume manufacturing. Typical timelines: formulation & pilot testing 4–8 weeks, stability verification 4–12 weeks depending on claims, and mass production lead time 6–12 weeks after approval. Minimum order quantities depend on format—contact us with your target SKU and annual volume so we can propose an optimal plan.
