Sodium

What it is

The main electrolyte in your sweat — and the one you lose fastest.

What it does

Keeps your blood volume up, your fluids balanced, and your muscles firing. Under-replacing it is why you feel flat and headachy after sweaty sessions.

The dose that works

Depends on the job: 700mg pre-training (Pre), ~400mg per serving during long work (Fuel), 1,000mg for dedicated rehydration (Hydrate).

Where it lives in the system

Pre, Fuel, and Hydrate — dosed differently for each moment. Zero overlap.

Good to know

Most hydration brands underdose sodium because salt scares people. If you sweat, you need it.
