Factory Strength: Professional Foundation Backed by Scale and Certifications
Yiwu Liuma Trading Co. Ltd. has built a solid operational foundation since its establishment, with total capitalization ranging from US$2.5 million to US$5 million and a team of 51-100 skilled professionals, ensuring stable production capacity and efficient project execution. What sets the company apart is its unwavering commitment to quality, as reflected in its adherence to rigorous international standards—its Vitamin D3+K2 softgels hold authoritative certifications including GMP, HACCP, QS, and ISO. These certifications cover every stage of production, from raw material sourcing to softgel manufacturing and packaging, guaranteeing that each product meets global food safety and supplement quality requirements.

The company’s production system is designed to handle both large and medium-scale OEM orders. With a clear pricing structure (US$4 per unit for orders ≥10,000 units, US$4.8 for 1,000–9,999 units, and US$5 for 100–999 units), it provides transparent cost control for brands, whether they are launching new products or scaling existing lines. Additionally, strict adherence to “cool and dry place” storage standards ensures the stability and efficacy of the softgels from production to delivery.
Product Advantages: Science-Backed Formulas and Consumer-Centric Design
Liuma’s Vitamin D3+K2 softgels stand out in the market with a combination of powerful nutritional benefits and user-friendly features, making them a preferred choice for OEM partners.
First, the potent 2-in-1 formula delivers 5,000 IU of Vitamin D3 (as cholecalciferol) and 100 mcg of Vitamin K2 (as MK-7) per serving—an optimal ratio scientifically proven to support calcium absorption, bone health, and immune function. This targeted formulation addresses the core health needs of adult consumers (men and women), while explicitly excluding unsuitable groups (children and newborns) to ensure safety.
Second, the product prioritizes purity and accessibility. It is free from GMOs, gluten, and soy, catering to consumers with dietary restrictions or sensitivities. Infused with sunflower seed oil, the softgels boast efficient absorption, while the optional pomegranate flavor and multi-color customization options enhance consumer appeal. Each bottle contains 300 softgels, offering long-term value for users, and the 24-month shelf life provides brands with flexible inventory management. The softgels are also designed to be easy to swallow, reducing barriers for daily consumption.
Service Support: Tailored Solutions for Seamless Collaboration
Yiwu Liuma understands that successful OEM partnerships rely on more than just quality products—it requires responsive, customized service. The company offers end-to-end support for brands: it provides free samples to help partners verify product quality upfront, and accommodates personalized requests for flavors (such as pomegranate or custom options) and colors, allowing brands to align the product with their unique positioning.
For communication and collaboration, Liuma’s official homepage serves as a convenient platform for inquiries, order tracking, and negotiation, streamlining the entire OEM process. While details like payment terms and small-order policies can be adjusted based on specific 合作 needs, the company maintains transparency and efficiency to ensure a smooth experience. Moreover, its compliance with global certifications means brands can confidently market the products under their own labels, without concerns about regulatory hurdles.
