Cheryl, I am but with so many combinations of how it can be written, it's slow going to find them all.
Downtown, like DanL said, the K2 is hard to find in high enough doses that would be affordable. In Japan they use it for osteoporosis regularly in the same dose of 45mg/day but it's by Rx.
The man I read about in the case study received combination therapy with oral vitamin K2 (menatetrenone, 45 mg/day) and vitamin D3 (alfacalcidol, 1 μg/day)*7 instead of chemotherapy. [*7.
