Helps blood clot: Vit K is necessary in the cascade for clotting. Infants dis not have enough Vit K in the old days and would present with fatal hemorrhaging at 7-8 days-called Hemmorhagic Disease of the Newborn. Fortunately this is rarely seen today. There is tremendous benefit at birth where the recommendation is for an injection of 1 mg right after birth.

The K2, K5, K7 are also close cousins that help with maintaining bones, reduce fractures, and slow down bone density loss in osteoporosis, and helps with absorption of calcium and are ubiquinols.

You will...: Vitamin k promotes clotting of blood by making more factors that promotes this. Greens and broccoli are rick in vitamin k. But people susceptible to clotting can be adversely affected, especially if on coumadin (warfarin). But for most of us this not a concern.

An essential vitamin: Vitamin k is essential for our blood to form clots and stop us from bleeding. It may also be involved in bone health. Vitamin k is in kale, spinach, turnip greens, collards, swiss chard, mustard greens, parsley, romaine, green leaf lettuce, brussels sprouts, broccoli, cauliflower, and cabbage. The bacteria in your intestinal tract make some vitamin k also.
