The sample size in their study was small, which is often the case for MDS studies, but it's promising news, especially since menatetrenone had multiple beneficial effects among these patients (on hemoglobin, platelets, and ANC) and no serious side effects.
Menatetrenone and menaquinone are names for one type of vitamin K, and vitamin K (found in green leafy vegetables) is known to have an effect on blood clotting. It shouldn't be taken with medications that also affect blood clotting, such as warfarin (coumadin). Vitamin K is harmless for most people but anyone receiving other treatments should ask their doctor about vitamins and supplements that they are interested in or that they are already taking.
