Redefining Drug‐Nutrient Interactions

Currently, a standardized definition and classification system for drug‐nutrient interactions does not exist. This may explain the disparity in the perception, recognition, and management of drug‐nutrient interactions among clinicians and researchers. The purpose of this article is to redefine and systematically classify drug‐nutrient interactions according to the most recent understanding in drug and nutrient metabolism and drug‐drug interactions. Drug‐nutrient interactions can be broadly classified into four types based on their mechanisms. This definition and classification system should facilitate patient management, clinical and didactic training for practitioners, and future research direction in this area.
