Vitamin K in nori seaweed
by: Anonymous

I know that nori seaweed contains vitamin K but how much? I take Coumadin. My doctor has instructed me that I can consume some vitamin K each day, but I must limit my intake. I'm dying for some sushi. Help!

Any information on mcg of Vitamin K in above list?
by: Anonymous

Some sources say that nori, although it has vitamin K has a very small amount (8 mcg for a sheet). Kombu for a 1 inch piece negligable, a cup of wakame around 5 mcg, laver, 4 mcg for a cup. Then other sources say seaweed is an excellent source of vitamin K, alluding to even as much as Kale. I had to obtain info from various sources, most of which are conflicting. So, I'm confused! Is there any table with the mcg of each type of seaweed? As a side note, when taking coumadin/warfarin - you can have vitamin K foods, the key is keeping the amount consistent day-to-day.

Seaweed, laver
by: Anonymous

Nori is the Japanese name for the edible seaweed species of the red algae genus Porphyra, including P. yezoensis and P. tenera. It is called laver in Wales and other English-speaking countries[1]. I checked with the USDA on their National Nutrient Database for Standard Reference and this is what they report for Seaweed, laver, raw.
