    It indeed it. I need to update. Currently I'm taking the Thorne K2....a drop every 3ish days depending on when I think of it. For a couple of years I did take 5 mg per day though, eventually reducing that over time.

    Shouldn't take k2 with warfarin. Though I always wonder if clotting issues are potentiated by a diet high in omega 6. Warfarin blocks k2 and is thus associated with the calcification of arteries.

    150mcg seems like a bit much. Would anywhere close to that much possibly be found in nature? 1 cup of natto, 300 something calories and enough soy to grow a man breasts only has 40mcg. I have been taking 120mcg every 3 days, is there a good reason to take more?
    Stabby: I am no expert, I was just going by what the article that said:
    "Although the exact dosing is yet to be determined, Dr. Vermeer recommends between 45 mcg and 185 mcg daily for adults. You must use caution on the higher doses if you take anticoagulants, but if you are generally healthy and not on these types of medications, I suggest 150 mcg daily."

    If anyone is familiar with other research or recomendations i am all ears.

    Natto actually has about 1000mcg of MK-7 per 100g serving, so 150mcg per day is in no way too much I think. Personally, I have a 75g pack of natto, scrambled eggs, and a mini cup of vinegared mozuku seaweed (is lightly sweetened unfortunately) for breakfast almost every day. No ill effects that I can tell, and there are just too many confounding variables for me to link health improvements I've noticed solely to the MK-7 and whatever MK-4 I get from eggs etc.

    Where did you get 1000mcg? Nutritionfacts says 40 per cup.

    I think Nutritionfacts might be listing only the K1 content or something... K2 isn't (yet) typically measured as far as I can tell

    MK-4 or MK-7? Stephen at wholehealthsource seems to hold MK-4 in higher regard whereas others like WAPF like MK-7 from what I have read.

    If you couldn't only supplement one, which form would it be?
