Factory Excellence: Certified Production for Global Trust
Biocaro’s state-of-the-art manufacturing facility in Zhengzhou, Henan, is the backbone of its reliable partnerships. Boasting international certifications including GMP, HACCP, QS, and ISO 9001, the factory adheres to strict quality control protocols across every production stage. From sourcing premium raw materials to final packaging, each batch undergoes meticulous testing to meet global regulatory requirements.

With a focus on flexibility, Biocaro caters to partners of all sizes. The accessible 500-bottle minimum order quantity (MOQ) empowers emerging brands to kickstart their product lines, while the factory’s scalable capacity efficiently handles large orders of 5,000+ units. Free samples are provided to validate quality, and the product’s 24-month shelf life ensures extended market viability—key for inventory planning and brand reliability.
Product Differentiators: Science-Backed Efficacy & Superior Absorption
Biocaro’s Vitamin D3+K2 Liquid Drops stand out with a formulation designed for maximum impact. Each 2ml serving packs 10,000 IU of Vitamin D3 (250mg) and 200mcg of Vitamin K2 as MK-7, a dynamic duo that supports bone density, cardiovascular health, and immune function. This synergistic blend addresses core consumer health needs, from mitigating vitamin D deficiencies (a global concern) to fortifying overall wellness.
Crafted with coconut oil for enhanced bioavailability, the liquid format outperforms traditional pills and capsules—ensuring faster absorption when taken sublingually or mixed into drinks. The product is 100% natural, non-GMO, and free from common allergens (dairy, soy, wheat, eggs, nuts), making it inclusive for diverse consumer demographics. Its "sunshine replacement" positioning resonates with those with limited sun exposure, adding a strong selling point for partner brands.
Competitive Edge: Flexibility, Value, and Speed to Market
Biocaro’s OEM/ODM services are engineered to drive partner success. Customization is at the forefront—partners can tailor private labels, packaging designs, and dosages to align with their brand identity and target audience. Competitive FOB pricing, starting at $2 per unit for orders over 5,000 bottles, ensures healthy profit margins, while tiered pricing for smaller orders (1,000–4,999 units at $2.5; 500–999 units at $3) accommodates growth stages.
Logistics and payment flexibility further streamline partnerships. Multiple shipping options—door-to-door express (3–7 days), air freight (7–15 days), and sea shipping (15–60 days)—cater to varying timelines and budget needs. Accepted payment terms (TT, LC, PayPal, Western Union) and immediate production upon prepayment ensure quick turnaround, helping partners capitalize on market trends faster.
