Jarrow Formulas MK-7 - 60 Softgels

What is Vitamin K2 (MK-7) and why is it important?

Vitamin K2, also known as menaquinone, is a fat-soluble form of vitamin K that plays a crucial role in bone and cardiovascular health. Unlike vitamin K1 (phylloquinone), found in green leafy vegetables, K2 is found in fermented foods and animal products, and is more effective at activating vitamin K-dependent proteins outside the liver. Jarrow Formulas MK-7 provides menaquinone-7, the most bioavailable and long-acting form, ideal for maintaining stable levels in the body.

Benefits of Vitamin K2 for bone and cardiovascular health

Vitamin K contributes to normal blood clotting and the maintenance of normal bones. These are two benefits supported by the European Food Safety Authority (EFSA). K2 activates osteocalcin, a protein that binds calcium to the bone matrix, and matrix Gla protein (MGP), which prevents arterial calcification. By combining these mechanisms, vitamin K2 supports both bone density and vascular flexibility. Jarrow Formulas MK-7 offers an optimal dose in an easy-to-absorb softgel.

How does vitamin K2 MK-7 differ from other forms?

There are several forms of vitamin K2: MK-4 (menaquinone-4) and MK-7 (menaquinone-7). MK-7 stands out for its longer half-life in blood, which allows for sustained activation of vitamin K-dependent proteins throughout the day. While MK-4 requires multiple daily doses, MK-7 is administered once a day. Additionally, MK-7 is naturally sourced, obtained from the fermentation of soybeans (natto), and is the most studied form for its benefits. Jarrow Formulas uses high-purity menaquinone-7, guaranteeing its effectiveness.

Who is this supplement suitable for?

Jarrow Formulas MK-7 is suitable for adults who want to maintain strong bones and a healthy cardiovascular system. It is especially useful for people with low dietary intake of vitamin K2, such as those who do not consume fermented foods. It can also be beneficial for postmenopausal women, who have a higher risk of bone loss. This supplement is suitable for vegetarians (the capsules are bovine gelatin, not suitable for vegans) and is free of gluten, soy, and dairy. Always consult a healthcare professional before starting any supplementation, especially if you are taking anticoagulants.
