Just starting to look at this,not much info really,but there is some discussion
on vitamin K in the spinach thread.
K1 from veggies/spinach
K2 MK4 from grass fed animal products
K2 MK7 from Natto bacterial fermentaion
K3 synthetic dont take it.
As for K2 we are not getting too much since there is a loss in the diet if animals are not eating grass or chicken eggs which are not pastured. Possible reason Paleo works if eating pastured animal products. Factory farming probably started sometime in the 1930's so suspect a loss of K2 in the diet since then.
Japan low but increasing incidence of UC since 70's,suspect western diet and less eating of traditional Japanese foods,might be going on.
Here is a general rundown on K.
Here is some confounding info on UC/K/iron/Vitamin E.
They are saying that oxidized vitamin E inhibits bacterial vitamin K in the gut.
Spinach has lots of iron and K1,if this interacts with your vitamin E stores, this might be a possible mechanism of action of the spinach.
Will keep looking but don't expect to find much. I have taken lots of K1 through
the years,does not help if at all for the UC.
Vitamin K2 and D are linked,for calcium deposits,what else might
be going on that they dont know about. We all know there is a vitamim D
link with UC, perhaps low k2 intake might be a problem,where the vitamin D
does not work right.
Also interesting to not that antibiotics may have wiped out our vitamin k
bacteria in the gut, Natto might help,also read VSL3 has some bacteria that
promote vitamin K.
UC k and d link.
This uses K3,not advised but there is a link.
Vitamin E low with low K in IBD.
Vitamin K and bacteria growth in the gut,MAP and others need it.
This is from early work,very good read.
Vitamin K cheese data base,High fat Edam is best,must be aged fermented as far
as I know.
