I just read these long posts on pinal gland calcification and vitamin K:
The Pineal Gland and its decalcification
I’ve seen lots of mention of vitamin K for cancer prevention and treatment.

TESTED SOURCES of Vitamin K2:
Natto (fermented soy)
Goose Liver
Cheeses
Egg Yolk
Butter
Chicken Liver
Fatty Meats
Sauerkraut
OTHER PROBABLE SOURCES:
Goose, Duck and Chicken Fat
Crustacean “Butter” (Hepatopancreas)
Bone Marrow
Other Organ Meats
Fish Eggs
Fermented Cod Liver Oil

K2 seems to be only in sauerkraut (for vegans) and we do eat that occasionally.  Too bad it’s not in whipped cream as I sometimes splurge.
K1 is in greens and we eat lots of those. So we’re probably ok.

The research indicates that a reversal of clacification is possible:
“First it was demonstrated that induced arterial calcification has been shown to be inhibited completely by vitamin K2 in vivo.
Then in a new study, the researchers looked at the potential to regress calcification.
Arterial calcification was induced in rats by interfering in the vitamin K-metabolism, by adding the vitamin K-antagonist warfarin to their diets. Vitamin K acts directly on matrix Glaprotein which is the strongest inhibitor of arterial calcification presently known. The rats were divided into two groups, a control group with vitamin K added to the diet, and a warfarin treated group to induced calcifications. After six weeks of treatment with warfarin, the rats had developed significant calcifications. At this point, the warfarin treated rats were divided into four groups and fed a standard diet plus 1/ Warfarin, 2/ vitamin K1 at normal dose, 3/ Vitamin K1 at high dose, and 4/ vitamin K2 at high dose.
During the second six week period, the calcifications in the warfarin treated group continued linearly, and remarkably, in the group receiving a normal dose of K1 continued comparably, demonstrating that the normal amount of vitamin K in the diet had no benefit:
In contrast, high vitamin K intake (both K1 and K2) not only blocked the progress of further calcium accumulation, but led to an over 37 % reduction of previously accumulated arterialcalcium precipitates within 6 weeks.
It is interesting to note that in the high K1 group, the vitamin K1 converted into vitamin K2 to such an extent that tissue concentrations were similar to the K2 supplemented group.
Additionally, the regression of arterial calcification was accompanied by restoration of arterial distensibility, or elasticity, in the high vitamin K groups to a similar level as in the control rats.”

Have to do some more research on a slow day.  I just don’t take supplements, even when I buy them.  They sit and get old.
