Do green, hot, bell, or any other peppers affect inr when taking warfarin?

Possibly: Bell peppers contain roughly 22% of the daily vitamin k allowance (17mcg) per serving. Considered relatively low in vitamin k. Compared with leafy greens such as spinach, etc has 560% per serving. As always however, any sudden dietary change must have a discussion with the prescribing physician and a follow up INR test within 1 week of the change in diet to determine its effect on the INR.
