2 interactions related to endurance
electrolytes + carbohydrates
Sodium and glucose share the SGLT1 cotransporter in the small intestine; their co-ingestion drives faster water absorption than either alone (the basis of oral rehydration therapy). Carbohydrate also delays gastric emptying slightly while providing exercise fuel.

citrulline + arginine
Oral arginine has poor bioavailability due to extensive first-pass metabolism. Citrulline bypasses the liver and is converted to arginine in the kidneys, sustaining elevated plasma arginine. Combined oral dosing produces a faster and higher plasma arginine peak than either alone, increasing nitric oxide synthesis.
