Vitamin K

Vitamin K plays a role in bone growth and blood clotting by aiding in calcium transport throughout the body. The UMHS notes that vitamin K's ability to help blood clots form has been utilized by doctors in treating overdoses of the blood-thinning medication, warfarin. Vitamin K is most prevalent in leafy green vegetables, but some forms of rice contain vitamin K as well. Long grain brown rice provides the highest amount of vitamin K, at 1.2mcg per cooked cup, while wild rice provides about two-thirds the amount. White rice, unless is has been enriched, contains no vitamin K.
