A 2025 review article published in the journal Performance Nutrition concerning the topic of sodium intake for athletes before, during, and after exercise.
- Authored by Alan J. McCubbin, the review examines the common rationales and beliefs athletes, coaches, and practitioners hold regarding sodium consumption, often contrasting these with the current evidence and lack of specific guidelines.
- The article concludes that daily sodium supplementation is generally unnecessary, but that acute sodium loading before exercise can be useful for hyperhydration, and that sodium intake during exercise should be guided by its relationship with fluid balance rather than simply replacing total sodium losses.
- The core message stresses that the water-sodium relationship is the main driver influencing health and performance outcomes, particularly concerning conditions like exercise-associated hyponatraemia (EAH).
