Vitamine K2 120 mcg MK-7 | Issue du natto | Soutien des os et du cœur | 120 capsules végétales

Vitamin K2 as menaquinone-7 (MK-7) is a fat soluble vitamin that activates two key vitamin K-dependent proteins: osteocalcin, which directs calcium into bone matrix, and Matrix Gla Protein (MGP), which inhibits calcium deposition in soft tissues including arterial walls. Vitamin K2 MK-7 supports bone and teeth health and cardiovascular wellness. Consult a healthcare practitioner before use if you are taking blood thinners.

Vitamin K1 (phylloquinone) is found in leafy green vegetables and is primarily used by the liver for blood clotting factor synthesis. Vitamin K2 (menaquinone) is found in fermented foods and animal products and is preferentially used by peripheral tissues particularly bone and blood vessel walls to activate osteocalcin and Matrix Gla Protein. K2 is the form relevant to bone mineralization and arterial calcium regulation; K1 does not effectively activate these extrahepatic proteins.

Natto is a traditional Japanese fermented food made from soybeans and is the richest known dietary source of menaquinone-7 (MK-7). Natto has been consumed in Japan for over a thousand years and is the food source from which MK-7 was first identified and characterized. MK-7 derived from natto is 100% plant based, making it suitable for vegans and vegetarians. Soy protein is removed during extraction consult a healthcare practitioner if you have a severe soy allergy.

Matrix Gla Protein (MGP) is the most potent known inhibitor of arterial calcification. Without adequate vitamin K2, MGP remains in its inactive (uncarboxylated) form and cannot prevent calcium from depositing in arterial walls and soft tissues. Vitamin K2 MK-7 activates MGP through carboxylation, supporting arterial flexibility and vascular health. Consult a healthcare practitioner for advice specific to your cardiovascular health needs.

Osteocalcin is a protein produced by bone forming cells (osteoblasts) that binds calcium into the bone matrix. Without adequate vitamin K2, osteocalcin remains in its inactive (uncarboxylated) form and cannot effectively incorporate calcium into bone. Vitamin K2 MK-7 activates osteocalcin through carboxylation, enabling it to bind calcium and support bone mineralization and density. Consult a healthcare practitioner for advice specific to your bone health needs.

Vitamin D3 increases calcium absorption from the intestine. Vitamin K2 MK-7 directs that absorbed calcium toward bone (via osteocalcin) and away from soft tissues (via MGP). The two vitamins work together in calcium metabolism D3 increases the supply of calcium available to the body, while K2 ensures it is deposited in the right places. Many adults take D3 and K2 together for comprehensive bone and cardiovascular calcium support.
