How do you get vitamin K?
Adults get vitamin K from food — mainly leafy green vegetables — and from bacterial synthesis in the gut. Babies have very little vitamin K in their bodies at birth because only small amounts of the vitamin pass through the placenta. Also, the bacteria that produce the vitamin in the newborn’s intestines are not yet present. Breast milk contains only low levels of vitamin K, and it may take weeks to months for the infant’s ‘sterile’ gut to become established and functional. Infants are therefore predisposed to having low vitamin K levels, resulting in low levels of vitamin K-dependent clotting factors, and an increased risk for bleeding, termed vitamin K deficiency bleeding.

How does vitamin K help bone?
Vitamin K aids bone health in a number of ways: 1 After it’s carboxylated by vitamin K2, osteocalcin can latch on to calcium and bind it to hydroxyapatite crystals forming the bone matrix. (Think of carboxylation as adding a trailer hitch to calcium, allowing it to be towed into and attached to bone.) (Bügel S, Proc Nutr Soc 2003) 2 Vitamin K2 also teams up with vitamin D3 to increase the production of Gla-proteins, including osteocalcin in osteoblasts (the cells that build bone), while also inhibiting the production of osteoclasts (the cells that break down bone). (Plaza S, Lamson D. Alt Med Rev 2005, Masterjohn C. Med Hypotheses 2007; Yamaguchi M, Sugimoto E, et al. Mol Cell Biochem 2001; Yamaguchi M, Uchiyama S, et al. Mol Cell Biochem 2003) 3 K2 works synergistically with bisphosphonate drugs, such as Fosamax, which lessen bone loss by poisoning osteoclasts (the cells that break down old bone). In a study of postmenopausal women with osteoporosis, fractures were experienced by 2 out of 25 women taking a bisphosphonate, 6 of 24 women taking calcium lactate, and only 1 of 26 women taking vitamin K and a bisphosphonate. (Iwamoto J, Takeda T, et al. Yonsei Med J 2003)
What happens when vitamin K is insufficient?

Which vitamin is used to carboxylate clotting factors?
K1 is the preferred form used in the liver to carboxylate clotting factors, while K2 is preferentially used in the rest of the body to carboxylate the other vitamin K-dependent Gla-proteins, including osteocalcin, which is essential for bone health, and matrix-Gla protein, which prevents calcification of soft tissue, i.e., blood vessels and organs.
How long does it take for K2 to be absorbed?

Is vitamin K fat soluble?

Is vitamin K1 a common source?
Several widely available foods are rich sources of vitamin K1, but vitamin K2 less common. Your body can partly convert vitamin K1 to K2. This is useful, as the amount of vitamin K1 in a typical diet is ten times that of vitamin K2. However, current evidence indicates that the conversion process is inefficient.
