Can VKORC1 help with sleep?

There is no scientific evidence that VKORC1 (vitamin K epoxide reductase complex subunit 1) directly affects sleep. This gene is primarily known for its role in vitamin K metabolism and the metabolism of anticoagulants like warfarin. Claims linking VKORC1 to sleep quality or duration lack a solid evidence base and should be considered marketing or speculative. Consumer DNA tests often report associations with very small effect sizes that are not clinically meaningful. If you have sleep concerns, focus on established factors such as sleep hygiene, stress management, and medical evaluation—not on single gene variants.
