electrolytes + carbohydrates
Sodium and glucose are absorbed together by the SGLT1 cotransporter in the small intestine, and their co-ingestion pulls water across the gut wall faster than either does alone. This is the basis of oral rehydration therapy and of modern sports drinks, where a fluid carrying both carbohydrate and sodium hydrates faster than water while also supplying fuel during prolonged exercise.

citrulline + arginine
Citrulline and arginine are both precursors to nitric oxide, the molecule that relaxes blood vessels and improves blood flow to working muscle. Each has a different limitation, and taking them together addresses both at once.
