Vitamin K, often a source of confusion, is comprised of different forms, notably Vitamin K1 and Vitamin K2. Understanding their differences is crucial for appreciating their unique health contributions.

Vitamin K1: The Blood Clotting Factor
Vitamin K1, also known as phylloquinone, is primarily found in leafy green vegetables such as spinach, kale, and broccoli. Its main recognized function in the body is its essential role in blood coagulation. K1 is quickly processed by the liver, and its impact is largely centered on enabling the blood to clot properly, preventing excessive bleeding. While important, its influence on bone and cardiovascular health is considered less direct compared to Vitamin K2.

Vitamin K2: Beyond Blood Clotting
Vitamin K2, known as menaquinones, exists in several subtypes, with MK-4 and MK-7 being the most studied. Vitamin K2 is found in animal products like egg yolks and dairy, and crucially, in fermented foods such as natto. The key distinction of K2 lies in its role in calcium metabolism. It activates proteins like osteocalcin and matrix Gla protein (MGP). Osteocalcin helps direct calcium to bones, promoting mineralization and strength, which is vital for preventing osteoporosis. MGP prevents calcium from depositing in arteries, thereby supporting cardiovascular health. This dual action is why the vitamin k2 mk7 for bone health and vitamin k2 mk7 cardiovascular benefits are so frequently discussed.

MK-4 vs. MK-7: A Closer Look
While both MK-4 and MK-7 are forms of Vitamin K2, MK-7 is particularly noteworthy due to its longer half-life and better bioavailability. This means MK-7 remains in the bloodstream longer, potentially offering more sustained benefits for bone and heart health. Research indicates that MK-7 may be more effective in improving bone mineral density and reducing arterial calcification compared to MK-4. This distinction is important when considering supplementation, and understanding how to increase vitamin k2 intake often centers on finding good sources of MK-7.

Importance of Quality and Supplementation
NINGBO INNO PHARMCHEM CO.,LTD. supplies high-purity Vitamin K2 MK-7, ensuring that manufacturers can create supplements that effectively deliver these distinct health benefits. While dietary intake is important, supplementation can be a reliable way to ensure adequate levels, especially for the MK-7 form. Consulting with a healthcare professional is recommended to determine the best approach for individual health needs.
