Story summary

Intravenous lactate infusion raises circulating pro-BDNF within 15 minutes, lasting up to two hours in healthy adults.
Led by Dr. Marcus Moberg at the Swedish School of Sport and Health Sciences, 12 healthy adults participated.
Findings show lactate functions as a signaling molecule linking physical exertion to neurochemical benefits, but infusion cannot replace high-intensity exercise.
