摘要

The present invention is directed to compositions comprising a nanoparticulate vitamin K2 having improved bioavailability. The nanoparticulate vitamin K2 particles of the composition have an effective average particle size of less than about 2000 nm and are useful in the prevention and treatment of osteoporosis. The invention also relates to a controlled release composition comprising a vitamin K2 or a nanoparticulate vitamin K2 that in operation delivers the drug in a pulsed or multi-modal manner for the prevention and treatment of osteoporosis.
