What Is Vitamin K2 Powder
Vitamin K2 is a group of fat-soluble compounds known as menaquinones (MKs). They play a similar role in bone and vascular health. VK2 has ten subtypes, from MK-4 to MK-13. Sunjoy manufactures Vitamin K2 (MK-7) powder.
Vitamin K2 activates osteocalcin, which helps bind calcium to the bone matrix. In this way, VK2 supports bone health.
Vitamin K2 also activates Matrix Gla Protein (MGP). MGP regulates calcium deposition in vascular tissues. This allows VK2 to help maintain normal vascular function through calcium regulation.
Main Functions of Vitamin K2
Vitamin K2 helps the human body utilize calcium properly. It guides the calcium to the bones and helps the bones become stronger and have a higher density. In this way, it helps lower the risk of bone fractures. This is essential for growing children and older adults.
Sunjoy provides nature-sourced VK2 powder. You can make it a VK2 supplement or add it to VD supplement products as a classic combo.
Sometimes, calcium can accumulate in the wrong places. This will make the blood vessels harder and stiffer. Vitamin K2 can help reduce these cases. It can help remove dangerous calcium buildup from your blood vessels and keep them soft and elastic. You can highlight this function in the promotion of VK2 supplements.
Vitamin K2 can help the human body handle sugar better. It helps the body maintain normal insulin function. This is good for maintaining a stable blood sugar level. You can apply our VK2 powder in your supplements and food products for metabolic health support.
Many people suffer from muscle cramps, especially at night. Vitamin K2 can help relax the tight muscles. It can help lower the frequency, reduce the cramping time, and alleviate the pain. Clinical research has explored the relationship between Vitamin K2 and muscle health in various populations.
Sports require high energy. Vitamin K2 boosts energy centers even when oxygen is low. It helps your muscles recover and strengthen your joints. When the athletes have abundant VK2, they are less likely to suffer from bone injuries.
If you produce functional beverages and functional foods, we recommend applying Vitamin K2 powder in your products.
Just like bones, teeth also require calcium. Vitamin K2 controls calcium delivery to your teeth. It helps with the growth of new dental tissue below the surface and makes the tooth structure stronger. VK2 also actively helps prevent cavities and tooth decay.
You can use Sunjoy VK2 powder in your nutrition products and dairy products.
There are tiny and fragile blood vessels in the eyes. Vitamin K2 helps maintain the elasticity of these microvessels. In this way, it helps with healthy blood flow to the eyes and protects vision in the long term.
You can use eye health as a marketing point for your VK2 supplements.
Vitamin K2 supports a healthy digestive system. It helps balance the bacteria living in your gut and supports the wellness of the whole digestive system.
You can apply Vk2 powder in your dairy products, yogurt products, and functional beverages and highlight its gut-health function on the packaging.

Coenzyme Q10 drives the production of cellular energy (ATP), while research shows that VK2 MK7 support the mitochondrial electron transport chain in a quite similar way.
You can apply them to your product and highlight the function of helping boost heart energy and cardiovascular health.
Magnesium is necessary for activating Vitamin D3 and bone-matrix mineralization. Magnesium glycinate is highly absorbable and mild for the digestive system.
You can combine Vitamin K2 (MK-7) with magnesium glycinate to optimize the utilization of calcium. This combination ensures that calcium enters the bone accurately and lowers the risk of vascular calcification.
Sodium hyaluronate is a natural lubricant which helps recover the cartilage and increase joint synovial fluid.
You can make sodium hyaluronate and VK2 as a combo for the recovery of both hard bone and soft joints. They help maintain the elasticity and flexibility of joints and improve the density of bones.
Calcium L-5-Methyltetrahydrofolate helps lower the blood homocysteine levels. In this way, it helps reduce the risks of endothelial damage and osteoporosis.
You can apply it with VK2 in your supplements as a golden combo for cardiovascular protection. They maintain the arteries clean and elastic.
MK-7 and MK-4 are both subtypes of Vitamin K2. In general, MK-7 has a longer half-life and higher bioavailability compared to MK-4. In fact, MK-7 has been shown to effectively support osteocalcin carboxylation.
Here is a comparison table of MK-7 and MK4 for quick reference.
| MK-7 vs MK-4 | ||
| Feature | Vitamin K2 MK-7 | Vitamin K2 MK-4 |
| Main Source | Natural Natto Fermentation, higher purity and activity | Chemical Synthesis, or from meat |
| Bioavailability | Long-lasting effect and long half-life, stays in the body longer with higher extrahepatic tissue utilization | Short half-life, does not significantly contribute to serum Vitamin K levels |
| Absorption and Transfer | Redistributed via low-density lipoproteins, ensuring sustained systemic circulation | Rapidly removed from the liver by lipoproteins |
| Effective Dosage | Microgram level: typically only 90 micrograms per day is required | Milligram level: requires 45 milligrams per day (500 times more than MK-7) |
| Dosing Frequency | Once daily, highly convenient | 3 times a day, 15 milligrams each time |
| Functional Benefits | Comprehensive Protection: Superior bone and teeth health, improved arterial calcification for cardiovascular health, etc. | Limited primarily to osteoporosis support |
| Molecular Structure | Longer side chain, Molecular Weight is 649.00 | Shorter side chain, Molecular Weight is 444.66 |
| Overall Summary | Far exceeds MK-4 in biological activity, bioavailability, and overall efficacy for daily health | Suited mostly for short-term, high-dose therapeutic use |
If you produce supplements and nutritional food, we highly recommend MK7 for you. MK-4 is commonly used in pharmaceutical products and certain regional markets such as Japan. It requires a large dosage and needs to be taken 3 times a day for its short half-life. MK-7 is much more convenient as a daily supplement for your consumers.
Note: dp-ucMGP (dephosphorylated-uncarboxylated Matrix Gla Protein) is an indirect biomarker reflecting the extent of Vitamin K2 lacking in the human body. When the value is high, it means the lack is severe.

Yes, we do. Sunjoy supports both bulk and small volume orders.
For small packages ranging from 1kg to 10kg, we use aluminum foil bags. For large packages, such as 25kg, we use cardboard drums with double-layered PE bags of pharmaceutical grade inside.
If you have special needs, we also support OEM, ODM, and other customized packing services. You can contact our service team for more details.
Vitamin K2 is easily decomposed by light. It should be protected from sunlight, heat, and moisture. The ideal storage temperature is from 5 to 25°C ( 41-77°F).
Sunjoy packs Vitamin K2 powder in cardboard drums to avoid light exposure. You can store the powder within the original packaging in suitable temperature and humidity conditions.
No. Vitamin K2 has a strict drug contraindication with Warfarin (Coumadin).
Warfarin prevents blood clots by blocking a type of enzyme that can make Vitamin K recycle. If one takes Vitamin K2 supplements, the effect of Warfarin will be directly reversed.
When the effect is reversed, the patient’s body will generate blood clots faster and significantly increase the risks of stroke and embolism.
We highly recommend noting this caution on your product label.
It should be taken with or right after meals. VK2 is highly fat-soluble. It needs dietary fat to be absorbed effectively. The gut requires bile acid to absorb it. Without fat, the bile acid could barely be secreted. Therefore, when taking K2 on an empty stomach, the absorption rate is significantly lowered.
We advise you to note this information on the product labels and select oil-based delivery systems (such as softgels or liquid drops) for the best absorption rate.
Because they control different stages of calcium metabolism.
Calcium is the core ingredient in bone matrix mineralization. But it cannot transport itself to the target.
Vitamin D3 stimulates osteocalcin and matrix gla protein (MGP). These proteins are inactive and uncarboxylated at this stage.
Vitamin K2 activates these proteins and makes them available for combination with calcium, locking the calcium in the bone matrix.
Vitamin K2 (MK-7) is required to be formulated as a Calcium + D3 + K2 complex for clinical efficacy and cardiovascular safety.
