Two fat-soluble vitamins in one capsule: vitamin K2 as MK-7 and vitamin D3. The specification is written on both assays, the carrier and the fill weight; the two vitamins are oil-borne and have to be distributed evenly in the fill.
The default is a 500 mg fill in a gelatin or HPMC shell, with an MCT carrier. The K2 and D3 doses, the carrier and the count are agreed before the batch.
| Format | Size | Shell / base | Best for |
|---|---|---|---|
| Capsule | 500 mg fill | Gelatin or HPMC shell; MCT carrier | Daily retail bottle |
| Capsule | Custom fill | Gelatin or HPMC shell | Higher-dose or different ratio |
| Bulk capsules | 5 kg / 10 kg | Gelatin or HPMC shell | Repacking and contract filling |
Vitamin K2 and D3 are fat-soluble and are usually carried in an oil. The carrier, the fill weight and the mixing step decide the uniformity; a poorly mixed oil fill can pass the assay on average and still fail individual capsule uniformity.
Both vitamins are sensitive to light and oxygen. An opaque bottle and a nitrogen blanket or antioxidant in the fill are the controls. The K2 form (MK-7) and the D3 source are stated in the specification, not inferred from the label.
K2 and D3 are assayed by HPLC; fill weight, uniformity and disintegration are tested per batch. Moisture, heavy metals and microbiology are tested to the destination market's limits. The shell is checked for seam integrity and appearance.
Send the K2 and D3 doses, the MK-7 form, the carrier, the fill weight, the shell type and the market. The most common mistake is to specify only the total fill weight without the two vitamin doses; the second is to choose a clear bottle for light-sensitive vitamins.
Vitamin K2 and D3 are sold here as food ingredients. No disease or therapeutic claims are made or implied. The brand owner is responsible for the label and the permitted statements in the destination market.

Shaanxi Rainwood Biotech Co., Ltd. is a botanical extract and food-ingredient manufacturer based in Xi’an, China. Since 2006 we have supplied powders, extracts and mineral salts to supplement brands and food manufacturers in North America, Europe and Asia.
For a capsule, the things that decide whether a batch is usable are the fill weight, blend uniformity, shell integrity, moisture and the pack. That is where we focus — the capsule itself, not tablet or gummy OEM. We supply 60 / 90 / 120 count HDPE bottles, with an induction seal and a desiccant where the material needs it.
Every batch is released against a written specification. The COA states the method, the release limit and the batch result; the TDS, allergen statement, GMO statement and certificate copies are available before the order. Third-party testing by SGS or Eurofins can be arranged on request.
