Exogenous Lactate: The Next Evolution in Endurance Fueling.
If high-carb fueling defined the last decade of endurance nutrition, lactate may define the next.
For years, endurance sports nutrition was built on simple sugars, electrolytes, and the belief that 30–60 grams of carbohydrate per hour was the practical ceiling. Exogenous lactate is the emerging category that challenges the idea that carbohydrate is the whole story, and it's built on two decades of exercise physiology.
How Carbohydrate Fueling Hit Its Limit
The first breakthrough came in the mid-2000s, when researchers led by Asker Jeukendrup showed that combining glucose and fructose let athletes absorb and oxidize more carbohydrate than glucose alone. By recruiting both the SGLT1 and GLUT5 intestinal transporters, intake climbed to 90 grams per hour – a major shift that redefined endurance fueling.
The science kept moving. Newer formulations moved toward a 1:0.8 glucose-to-fructose ratio, improving carbohydrate delivery while easing gastrointestinal distress. Paired with deliberate gut training, this created the modern high-carb era, where brands like Maurten, SiS, Enervit, Amacx, Precision Fuel & Hydration, and Santa Madre have made 100–120 grams of carbohydrate per hour a realistic target for elite athletes.
But there was always a second half to the equation.
Lactate Is a Fuel, Not a Waste Product
For decades, lactate took the blame for burning legs and fatigue. Athletes blamed fatigue and sore legs on "lactic acid buildup." Exercise physiologist Dr. George Brooks overturned that thinking with his Lactate Shuttle Theory, demonstrating that lactate is not metabolic waste but a valuable, and often preferred, fuel source. The body actively transports lactate between tissues and oxidizes it for energy, especially during prolonged exercise.
That reframing is the foundation of exogenous lactate.
