China Supplement Sourcing & Product Development | OEM/ODM

I help overseas supplement brands source, develop, and manufacture products in China—from supplier selection and formulation feasibility to sampling, packaging, production, and shipment coordination. My main focus is dietary supplements, nutraceuticals, and wellness products, including: - Tablets & capsules - Softgels - Powders - Gummies - Herbal / functional teas - Peptides & specialty ingredients - Private-label and custom OEM/ODM products I can support you with: • Manufacturer sourcing & factory verification • MOQ, quotation and supplier comparison • Formula/manufacturing feasibility communication • Sample development and follow-up • Packaging and labeling coordination • GMP / FDA registration / export-document verification • COA and third-party testing coordination • Factory visits and video inspections in China • Production timeline and quality follow-up • Supplier negotiation and shipping coordination I have hands-on experience supporting overseas clients with supplement projects from early supplier selection through actual production. For example, I have worked on projects involving custom multivitamin tablets, softgel formulations, peptides, herbal wellness products, and private-label supplements, coordinating directly with Chinese factories, R&D teams, packaging suppliers, and testing laboratories. My background includes a Master’s degree in Environmental Science, which gives me a strong analytical approach to raw materials, documentation, supplier qualification, and manufacturing processes. Looking for ongoing support? I also work as a long-term China sourcing partner for brands that regularly launch or improve supplement products. Instead of simply sending you a supplier list, I can continue supporting the project through sampling, production, packaging, inspection, and future product development. If you are sourcing or developing supplements in China, send me your product idea, formula, target quantity, and destination market. I can help you evaluate the next steps.
