Cliffs notes for those interested...
- With or without concurrent D supplementation, Ca supplements increase heart disease in women
- Vitamin D facilitates Ca absorption but doesn't "direct" it to the right place; K2 does that by activating 2 proteins, one that removes Ca from arteries, another that puts it in bones/teeth
- 50% of heart attack victims have normal cholesterol
- Over age 60, higher cholesterol is protective against heart disease and dementia
- CAC test available to measure Ca in 3 main arteries...it's a better predictor of mortality than your actual age
- Ballpark figure, you can remove 50% of arterial plaque in 6 weeks with sufficient K2 intake
- K2 used to be abundant in western food supply but has now disappeared as animal products have shifted from pastured to grain fed
- K2 also helps with insulin sensitivity, cancer prevention, and controls prenatal palatal/jaw growth <--- this is interesting as current prevailing theories on the epidemic of underdeveloped jaws include absence of breastfeeding (proper swallowing mechanics) and poor diet in childhood
- K2 supplementation in high doses in isolation generally ok (unlike A/D) unless combined with warfarin
- 100 mcg from food (2 pastured egg yolks or a small piece of brie/gouda) is a good maintenance dose
- She mentioned that Vit A is being unfairly maligned, it shouldn't be pounded in huge quantities but it does have a role to play
One thing I'm not sure about...she seemed to imply that 45 mg synthetic K2 (i.e. Thorne MK-4) is the equivalent dose to 100 micrgrams of MK-7 from food?!
