What to watch with VKORC1 and Schlaf?

VKORC1 is primarily known for its role in vitamin K metabolism and warfarin sensitivity. There is no robust evidence directly linking VKORC1 variants to sleep quality or disorders. Some speculative mechanisms suggest vitamin K might influence sleep via calcium regulation or inflammation, but these are not supported by GWAS or clinical trials. If you have VKORC1 variants, focus on well-established associations (e.g., warfarin dosing) and address sleep issues with proven strategies: sleep hygiene, consistent schedule, light management, and stress reduction. A DNA test alone cannot predict sleep outcomes. Evidence: unclear/speculative.
