VKORC1 encodes vitamin K epoxide reductase, an enzyme critical for recycling vitamin K, which in turn activates clotting factors (II, VII, IX, X) and bone proteins like osteocalcin. Well-studied variants (e.g., rs9923231) affect warfarin sensitivity and bleeding risk. However, there is no credible scientific evidence linking VKORC1 directly to sleep quality, duration, or circadian regulation. Claims that a VKORC1 test reveals anything about sleep are misleading and likely stem from marketing or vague extrapolations. While vitamin K might indirectly influence sleep through bone health or inflammation, any effect is negligible and not supported by genotype data. For sleep issues, factors like light exposure, melatonin, stress, and sleep hygiene are far more important. A VKORC1 genetic test provides no actionable sleep insights. Consumers should be wary of such myths and rely on evidence-based sleep advice.","area":"gesundheit","canonical_id":"gesundheit:canonical-658bb16c2335204f48e06fe8","id":"public-2f6e2e9a22e25e8d4ddcd0e0","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Myths vs facts: VKORC1 and Schlaf","score":30.30386966,"snippet":"The question about VKORC1 and sleep is a classic myth that can arise from overinterpretation of consumer DNA tests.

There is no credible scientific evidence linking VKORC1 variants to weight loss or metabolic rate. Claims suggesting such a connection are likely based on marketing rather than research.
