Description

 

Product Information

Vit MK7 (CAS 2124-57-4) belongs to the Vitamin K2 family, characterized by a side chain with 7 isoprene units. As a fat-soluble vitamin essential to human health, it stands out as the most bioavailable form of Vitamin K2-boasting easier absorption and longer-lasting activity in the body. Extensive research highlights its ability to support bone health by enhancing bone density, improving bone quality and strength, and promoting collagen synthesis, while it also plays a valuable role in supporting vascular health and overall wellness. Vitamin K2 has multiple isoforms, with MK-4 and MK-7 being the most prominent; while MK-4 is found in fermented animal products and some plant-based foods, MK-7 is primarily derived from fermented sources like natto.

 

As a professional Vitamin K2-MK7 supplier based in China, LonierHerb takes pride in our high-quality products sourced from non-GMO fermented natto-ensuring purity and natural origin. We offer a full range of specifications to meet diverse application needs, including 0.2%, 0.3%, 0.5%, 1%, and 1.3%.

Vit MK7

 

Efficacy and Features

1) It is fermented by natural natto bacteria, not artificially synthesized, and its production and manufacture fully comply with EU GMP and FDA operating specifications, ensuring more than 99%.

 

2) Vit K2 MK7 is a cofactor in vitamin K-dependent responses and a key factor in the carboxylation of osteocalcin.

 

3) Completely carboxylated osteocalcin is more conducive to helping calcium deposition into bones, while it can continuously promote uncarboxylated osteocalcin to complete its carboxylation reaction.

 

4) Most of the current osteoporosis prevention and calcium supplement products are mainly calcium and vitamin D3 products. If there is no MK7, calcium will easily be lost to the blood or other places after entering the body. Helps increase osteocalcin, but cannot help calcium enter bones, only vitamin K2-7 can activate osteocalcin and help calcium be absorbed by bones instead of being enriched in parts such as the heart or arteries, causing possible Cardiovascular diseases.

 

5) Only the synergistic effect of calcium, vitamin D3 and MK7 vitamin

can better utilize and absorb calcium, enhance bone health and stay away from the risk of cardiovascular disease.

 

6) There are various oil and powder grades: 1000ppm powder, 1500ppm oil, 2000ppm powder.

What is the difference between MK4 and MK7?

Bulk Vitamin K2 can be divided into several different subtypes, the most important being Menaquinone MK4 Powder and Menaquinone MK7 Powder, both of them are very important to the human body, so what is the difference between two different forms?

 

◆ Vitamin K2 MK-4

It is mainly found in animal products, including animal offal, egg yolks and animal fats. It is obtained by animals transforming vitamin K1, that is why the butter produced by cattle and sheep that eat fresh grass is rich in Vitamin K2. At present, most of them are obtained through chemical synthesis and are mainly used for symptoms such as osteoporosis.

◆ Vitamin K2 MK-7

Bulk Menaquinone Mk7 comes mainly from fermented foods, especially natto, which is currently the main source. Its side chain is longer than that of MK4, so it can exist in the human body for a long time, and its bioavailability in extrahepatic tissues is higher. Now it is widely used for osteoporosis, improving arterial calcification, treating Parkinson‵s disease.
