Myths vs facts: VKORC1 and menopause

The question of myths vs facts regarding VKORC1 and menopause cannot be answered from the provided context. VKORC1 encodes the vitamin K epoxide reductase enzyme and is primarily known for its role in warfarin sensitivity. During menopause, hormonal changes can affect bone metabolism (vitamin K is involved in bone mineralization) and cardiovascular risk. However, there is no robust evidence from the given sources linking VKORC1 variants directly to menopausal symptoms or altered vitamin K requirements. Consumer DNA tests like those from MyBody-X may report VKORC1 polymorphisms, but their clinical utility for menopause is not established. Consumers should be cautious of marketing claims that imply such a connection. Vitamin K supplementation should only be considered after consulting a physician, especially if taking anticoagulants. Evidence: unclear.
