Yes, I take it. K2 + MK-4 and MK-7 have proven to be beneficial in heart health.
The Rotterdam Heart Study, 4,800 participants for seven years, revealed that when the participants ingested quantities of vitamin K2 in their diet experienced a better cardiovascular condition than people who ingested the least. 21 High intakes of the vitamin K2 also indicated less calcium deposition in the aorta, whereas participants who ingested less K2 showed moderate to more severe calcification. Animal studies also indicate that vitamin K intake not only blocks the progress of further calcium accumulation, but also induces 37% regression of accumulated arterial calcification.
