Evidence check: VKORC1 in the context of stress

The provided context does not contain evidence linking VKORC1 to stress. VKORC1 is primarily known for its role in vitamin K metabolism and warfarin sensitivity. Any claim connecting it to stress is speculative and lacks human or mechanistic evidence in the given material. The evidence level is unclear. Consumers should be cautious about overinterpreting genetic data without robust clinical validation.
