There are two main forms: K1 (phylloquinone), found in green leafy vegetables, and K2 (menaquinone), produced by intestinal bacteria and also available in fermented foods. Vitamin K2 is subdivided into several types, the most studied being MK-4 (menatetrenone) and MK-7. MK-4 is the form found in animal tissues and supplements like this one from Carlson.\u003c\/p\u003e\u003cp\u003eThis vitamin plays a crucial role in activating vitamin K-dependent proteins, such as osteocalcin (for bone health) and matrix Gla proteins (for cardiovascular health). Therefore, an adequate intake of vitamin K2 contributes to the maintenance of normal bones and normal blood clotting.\u003c\/p\u003e\u003ch2\u003eHealth benefits of vitamin K2\u003c\/h2\u003e\u003cp\u003eAccording to the European Food Safety Authority (EFSA), vitamin K contributes to normal blood clotting and the maintenance of normal bones.

Recommended dosage\u003c\/h2\u003e\u003cp\u003eThe adequate daily dose of vitamin K2 can vary depending on age, health status, and diet. There is no specific recommended daily intake (RDI) for K2 in the EU, but there is for total vitamin K (men: 70 µg\/day; women: 60 µg\/day, according to EFSA). However, many people opt for higher doses for specific benefits.\u003c\/p\u003e\u003cp\u003eEach Carlson Vitamin K2 MK-4 capsule provides 1 mg (1000 µg) of menatetrenone, a higher amount than the RDI.
