Vitamin D3 Oil
Vitamin D3 Oil is cholecalciferol dissolved into a refined vegetable carrier oil at a standardised potency, sold as the workhorse liquid input for food fortification, dietary supplement softgels, and oral drops.
The format gives formulators a homogeneous, pourable concentrate that integrates cleanly with other lipid-soluble vitamins and bypasses the dispersion issues of powder forms in oil systems.
We source bulk Vitamin D3 Oil from top China manufacturers for our partners, working with several of them. The manufacturers are mostly in Shandong, Jiangsu and Shaanxi. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Common loadings are 1,000,000 IU per gram (the dominant export grade), 100,000 IU per gram for direct dropper use, and 4,000,000 IU per gram for high-potency softgel filling.
Carrier oils include refined soybean, corn, sunflower, MCT (caprylic/capric triglyceride), olive, and organic-certified options. MCT is preferred where oxidative stability and clear-fill softgel appearance matter; olive supports premium and Mediterranean-positioned products.
Antioxidant systems are clean-label friendly: mixed tocopherols, ascorbyl palmitate, and rosemary extract are typical. Allergen status (soy, peanut) is carrier-driven and called out on every CoA.

How We Help Source Vitamin D3 Oil
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Vitamin D3 Oil out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Vitamin D3 Oil together with other ingredients such as Vitamin C, Vitamin D3 and Vitamin E into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Cholecalciferol is recognised as a nutrient in food and supplement use across major regulatory frameworks. The U.S. FDA covers it under 21 CFR 184.1950 as GRAS for use as a nutrient and under specific food-standard regulations for fortified products.
The EU lists cholecalciferol in Regulation 1925/2006 as a permitted vitamin for fortification and in Directive 2002/46 for food supplements. JECFA has reviewed D3 and supports its use as a fortificant within established intake recommendations.
Pharmacopoeial monographs in USP, Ph. Eur., and JP cover identity and assay even when the material is produced to food rather than drug specifications. Halal, Kosher, and non-GMO certifications follow the carrier oil and the upstream lanolin handling chain.
Manufacturing Process
Cholecalciferol crystal or refined resin is dissolved into deodorised, low-peroxide carrier oil under nitrogen blanket. The mixture is gently warmed until fully homogeneous, then the antioxidant package is incorporated.
An in-process HPLC reading sets the final dilution. The concentrate is filtered, sampled for assay, peroxide value, acid value, and microbiology, then drummed under inert headspace.
Refrigerated storage and short pipeline residence times are the rule because the diluted active in a free-oil matrix is more exposed to oxygen and light than its crystalline parent. Lined steel drums with inert headspace and amber HDPE jerricans are the standard packaging.
