The evidence for ketone esters as an acute performance enhancer is mixed — some studies show a small benefit, some show none. The stronger signal is for recovery: ketones appear to enhance post-exercise glycogen resynthesis when consumed with carbohydrate. Used by Jumbo-Visma and other World Tour teams. Not banned by WADA. Expensive (~€30+ per dose) and mildly nauseating at larger doses. Unlikely to be cost-effective for most amateurs.
