if you want to get vitamin K in the real biologically active form get vitamin k2 you deliver eat the animal fruits don't think about getting it from spinach because that's not where you're gonna get the vitamin K it's been found to be biologically active
but the best way to get vitamin k2 is things like liver or egg yolks that is where you get this nutrient that is critical that is crucial for cardiovascular health
there's a much easier way to get vitamin k2 which is egg yolks liver meat etc animal foods even dairy that is from grass-fed cows or non-grass-fed cows usually has vitamin k2 in it
as we know from studies like the Rotterdam study vitamin K2 has a strong consistent repeatable reproducible Association with lower rates of heart disease lower rates of calcific aortic sclerosis but vitamin K1 doesn't so who cares how much vitamin K1 you get get vitamin K2 from animal Foods things like liver heart meat egg yolks butter cheese
there's lots of vitamin K in animal Foods it's just vitamin K2 not vitamin K1 and if you look at studies like the rdam study you see that vitamin K2 which is known as menaquinone and there are technically many different isoforms of vitamin K2 MK4 mk7 MK1 Etc but vitamin K2 is consistently associated in the rdam study and many others with improved outcomes in terms of longevity improved outcomes in terms of cardiovascular disease lower rates of calcific aortic sclerosis
