Timing Considerations: Divide doses throughout the day (TID preferred) to optimize absorption given saturable intestinal transport Can be taken with or without food
19 This anisotropic pattern suggests that geometry, polarity, and compartmentalization function as physical boundaries that shape the directionality of spread, effectively channeling ferroptotic injury along predefined anatomical paths
