What dose for vitamin K?

In one  study from the Netherlands, researchers recruited 325 postmenopausal women without osteoporosis. Half the women received a placebo and half received vitamin K2, 45 milligrams per day. 

The intervention period: three years.

Results: Bending strength, compression strength, and impact strength all improved in the K2 group, but not in the placebo group. Also, bone mineral content and femoral neck width increased in the K2 group, but not in the placebo group.

The detail about the femoral neck is a key point.

The femoral neck is a narrow section of the femur (thigh bone) located just below the ball-and-socket hip joint. When the femoral neck is fractured, the femur is often disconnected from the ball. In an aging population, that’s a common and very painful fracture.

Dietary sources of K2 include meat, liver, egg yolk, and fermented products such as yogurt and cheese. Vitamin K1 is mostly found in dark, leafy green vegetables and is converted to K2 in the intestine.
