Can You Take Polyunsaturated Fatty Acids with Vitamin K?

Research shows that diets rich in polyunsaturated fatty acids, such as corn oil, do not significantly affect vitamin K metabolism or the synthesis of vitamin K-dependent proteins. This suggests that taking polyunsaturated fatty acids and vitamin K supplements together is unlikely to cause any adverse interactions. No mechanism of interaction was identified between polyunsaturated fatty acids and vitamin K. The metabolism and utilization of vitamin K appear to be unaffected by the presence of polyunsaturated fatty acids.
