What athletes should know before using lactate-based fueling
Interested in lactate-based fuelling? Here is a grounded briefing on what the science currently supports, what it doesn't, and how to think about it.

Reviews, explainers, commentary and research updates on the science of exogenous lactate. Every article cites its sources and names its author.
Can lactate support glycogen recovery?
Lactate can be converted toward glucose and glycogen. Does that make it useful for recovery? The mechanism is real; the applied evidence is early.
Lactate, fat oxidation and metabolic flexibility
Lactate does not act in isolation. Its interaction with fat oxidation and substrate selection is central to understanding metabolic flexibility.
Lactate and the brain during exercise
Emerging evidence suggests the brain can use lactate as fuel. What might this mean for central fatigue and endurance? A measured look.
Exogenous lactate and endurance performance
The rationale for exogenous lactate in endurance sport is compelling on paper. Here is what the early evidence does — and does not — allow us to say.
Oral lactate supplementation: what do human studies show?
Human trials of oral lactate are still few. Here is a careful summary of what they have examined so far and why conclusions remain tentative.
Lactate as fuel: what the evidence says
Lactate is increasingly described as a fuel. What does the evidence actually support, and where do the open questions remain?
Lactate is not waste: the lactate shuttle explained
Lactate has long been blamed for muscle burn and fatigue. The lactate shuttle concept tells a very different story — one of lactate as a shared metabolic currency.
What is exogenous lactate?
Exogenous lactate is lactate taken into the body from outside, rather than produced internally. Here is what that means and why researchers are paying attention.
