Need a carb + electrolyte powder recommendation

Circling back, here. I’m trying to dig up evidence that chloride is needed during exercise. I have yet to find support for that idea in the literature.

Certainly, chloride is lost in large amounts during sweat, but I haven’t found convincing rationale or hard evidence that its replacement is merited.

Anyone got any links to literature evidencing that chloride is necessary or measurably beneficial in endurance fueling strategy?
