Therapeutic Uses

Growing, but not yet definitive, evidence suggests that vitamin K should be added to the list of nutrients helpful for preventing osteoporosis . 1 Based on its ability to help blood clot normally, vitamin K has been proposed as a treatment for excessive menstrual bleeding. 2 However, the last actual study testing this idea was carried out more than 55 years ago. 3 Vitamin K has also been recommended for nausea , although there is as yet no meaningful evidence that it really works.

Preliminary evidence suggests that vitamin K supplementation may help prevent liver cancer . 4 Very high doses of intravenous vitamin K have also been used to treat advanced liver cancer, with, perhaps, marginal benefits. 5
