“You need salt. Period.” @thereadystate Dr. Kelly Starrett works with folks trying to move better, and he sees what happens when sodium is too low — in elite athletes AND anyone who trains. Here’s what research shows: ⚡ Endurance performance: Pre-exercise sodium loading expands plasma volume (3.5-12.6%) and improves exercise capacity in the heat by maintaining blood volume and reducing cardiovascular strain. (PMID: 23075561; PMID: 25811813) ⚡ Half-Ironman triathletes: Athletes who replaced sodium lost in sweat finished 26 minutes faster than those who didn’t in a field study of actual race conditions. (PMID: 25943657) “If you want to be better at whatever it is you’re doing — running, lifting weights, swimming, biking — improving your salt intake will really up your game.” The research is there. The mechanisms are clear. You feel the difference when you get it right.
