Aspirin and coumadin have two separate functions. Coumadin is an anticoagulant where vitamin K is the antidote and we give it quite frequently. Vitamin K would work by making one of your coagulation pathways more "clotable." Aspirin... (more)

Many vitamins are not a single molecule, but a number of related molecules that have similar function. B12 is a good example, you can have methyl-B12, cyano-B12, hydroxy-B12, or adenosyl-B12. They all get converted to active B12 in the body,... (more)

Beta carotene, as found in plants, does not cause hypervitaminosis A. We only convert what beta-carotene we need to vitamin A. You might start to turn orange from all the beta carotene though. See: http://en.wikipedia.org/wiki/Beta-Carotene (more)

The CLO and butter is great but ideally you'll want pastured, raw butter. Supposedly you'll be getting lots of vitamin K this time of year (the spring) from pastured butter. Also pastured egg yolks. I wouldn't count on getting adequate D from sun... (more)

K1 appears to survive cooking at least just fine: http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/2926/2 K2 is going to be more from butter, eggs, natto etc. rather than vegetables. (more)

Fish oil slows clotting. For better or worse. Probably better than aspirin and the like tho since its an anti-inflamitory as well.
