saw this on a breast cancer forum, not sure why docs don’t discuss K2:
"Something I never see mentioned, which was never mentioned to me even when I saw an orthopedic specialist after breaking my foot, was that Vitamin K2 deficiency along with Vitamin D3 deficiency increases the risk of fractures.
Just look at the following research about it. Vitamin K2 works SYNERGISTICICALLY with Vitamin D3 to move Calcium out of blood vessels and soft tissue spaces into bones. Without enough Vitamin K2 it is very hard to get the Calcium into your bones. Not only that, but Vitamin K2 is important in lowering risks of Atherosclerosis and Coronary Heart Disease. This should be a major health article, but you don’t hear a word about it. Guess it might cut into the pricey, revenue generating big bucks the pharmaceutical industry gets with the Bisphosphonates
Vitamin K2 is not the same as Vitamin K 1, which is involved in blood clotting. There are a number of studies out of Japan where it is used in combination with Vitamin D3 for prevention and treatment of osteoporosis/osteomalacia. The research is using MK 4 and MK 7 types of Vitamin K2. MK4 is found in animal products like Gouda, Edam and Brie Cheeses. MK 7 is found in Natto, a weird Japanese food made from fermented Soy beans.
No Vitamin K2 supplements unless approved by your doctor if taking Blood Thinners."
