Background:

Menaquinone-4 is a vitamin K, used as a hemostatic agent, and also a adjunctive therapy for the pain of osteoporosis.

Menaquinone-4 (MK-4, 0, 1, 5, 10 μM) increases the ALP activity in Caco-2 cells. Menaquinone-4 (1 μM) significantly increases intensities of hSI expression[1].

Menaquinone-4 (K2, 0.2 g/kg diet) in HF-K2 group produces epididymal fat in C57BL/6J mice, and also increases the bone density of mice[2].
