When was the first mention of the interaction between warfarin and fermented soybeans?

Perhaps the first mention of this interaction was in 1978 , when it was suggested that the fermented soybean product natto could antagonize the effects of warfarin. 10 Since this article was published in Japanese and involved a food rarely consumed outside of Japan, it isn’t surprising that it didn’t receive much attention. A decade later, research by Kudo 11 confirmed the initial report. So, what accounts for this interaction? The answer is –vitamin K.

So, let us look at the data, starting with some basic background information about warfarin and vitamin K. Warfarin has been used for nearly 70 years for its anticoagulant effects. 1 Indications for its use include the prevention and treatment of thromboembolism (obstruction of a blood vessel by a blood clot that has become dislodged …

As can be seen from table 2, two types of tofu provide about 12 ug/100 g, although another type contained much higher values, but nothing like natto or broccoli, cabbage, and spinach. And most soymilks provide fewer than 10 ug/cup, although again, there is a range. 18 A cup of boiled soybeans provides 33 ug but that cup also provides more than 30 grams of protein. 18 Soybean oil is much higher in vitamin K than are other oils, but a tablespoon provides only about 21% and 28% of the adequate intake for adult men and women, respectively. 18 So, there is no reason to avoid most soyfoods based on their vitamin K content.

Since warfarin works by inhibiting the activity of vitamin K, patients using this drug need to be mindful of the amount of vitamin K they consume.

Patients on Warfarin Can Consume Soyfoods. The connection between the blood thinner warfarin and the consumption of soyfoods is by no means an obvious one. But from time to time, questions about this relationship arise, as was the case when a vegan recently expressed concern about consuming soyfoods because he is on warfarin.

Since warfarin works by inhibiting the activity of vitamin K, patients using this drug need to be mindful of the amount of vitamin K they consume. Consuming too much can inhibit the efficacy of the drug, thereby raising risk of developing blood clots. Too little vitamin K could result in excessive bleeding. In general, the goal is to maintain a consistent vitamin K intake so blood levels can be titrated accordingly. In the U.S., men and women over the age of 20 consume on average 118 and 123.5 ug/d of vitamin K, respectively, 8 which just about matches the adequate intake for men and exceeds the adequate intake for women by about one-third (table 1). So, with that background in mind, how does soy enter the picture?

Does soy milk affect INR?

Ingesting soy milk caused reductions in INR to ineffective levels in one patient who had been receiving a stable dose of warfarin, explains an article published in the December 2002 issue of the journal “Annals of Pharmacotherapy.”.
