Q & A with Dr. Jed Fahey

Q:  I am on Coumadin (blood thinner) and am told that I have to be careful about consuming broccoli due to high Vitamin K content.  Does Brassica® Tea contain Vitamin K as well?
 
A:  We have not been able to measure the amount of Vitamin K in Brassica Tea.  Accurate analysis is extremely difficult and unreliable because Vitamin K is not water soluble.  Analyses in the Brassica Chemoprotection Laboratory show that BroccoSprouts contain 1.35 micrograms of Vitamin K per gram of fresh sprouts.  This converts to 135 micrograms per 100 grams (which is much more than one would consume per day), or 38 micrograms per one ounce serving.  The Vitamin K content of market stage (adult) broccoli is reported as 205-270 micrograms per 100 grams, and one might consume 100 grams of adult broccoli at a time.  Other vegetables are reported to contain from 5 to about 1,500 micrograms per 100 grams.  Given that the broccoli extract in the tea comes from the sprouts, and the amount of SGS is reduced from 73 milligrams per one ounce serving to 15 milligrams per tea bag, and given that Vitamin K is not water soluble, we believe Brassica Tea contains very little Vitamin K.  However, certainly discuss this with your physician.
