Vitamin K2

 Vitamin K2, like its counterpart K1, is a fat-soluble vitamin that plays a crucial role in various bodily functions. However, it's mainly known for its role in bone and cardiovascular health. Here's a bit more detail:

1. Bone Health: Vitamin K2 is essential for bone mineralisation. It activates osteocalcin, a protein that helps bind calcium to bones and thus contributes to bone strength and density. Studies suggest that adequate intake of vitamin K2 may reduce the risk of fractures and improve bone health, especially in postmenopausal women at higher risk of osteoporosis.
2. Cardiovascular Health: Vitamin K2 also helps regulate calcium metabolism. It ensures calcium is directed to where it's needed, such as bones and teeth. It prevents it from accumulating in arteries and other soft tissues, which could contribute to arterial calcification and increase the risk of cardiovascular disease.
3. Other Functions: Some research suggests that vitamin K2 may have other potential health benefits, such as supporting immune function and possibly reducing the risk of certain cancers. However, more studies are needed to understand these effects fully.

Vitamin K2 is naturally found in fermented foods like cheese, natto (fermented soybeans), and sauerkraut, as well as in animal products like egg yolks and certain meats. It's also available in supplement form, often as MK-4 or MK-7 (different forms of vitamin K2).

As with any supplement, talking to a healthcare professional before adding vitamin K2 to your regimen is essential, especially if you're on blood-thinning medications or have any underlying health conditions.
