Lytework is a precision sodium dosing system for endurance athletes. Capsules, not drinks. Personalised to your sweat rate, not a fixed formula. Ninety seconds and you'll know if it's for you.
Sodium loss varies more between athletes than almost any other variable.
Two athletes the same age, same weight, same race — one can lose three times more sodium than the other in the same conditions. Most endurance products ignore this. They bundle sodium into a fixed-dose drink and assume one number works for everyone.
It doesn't. And underdosing sodium is one of the most common reasons fit, well-prepared athletes fall apart in the back half of long races.
Sodium, separated from fluid. Dosed to you.
Lytework is a sodium capsule. No flavour, no sugar, no drink mix. Designed to be taken on a schedule that matches your individual sweat rate and the conditions you're racing in — not a generic per-bottle dose.
To make that work, every Lytework athlete starts the same way: build a free hydration profile. It takes under two minutes and outputs an hourly sodium target and a capsule schedule built around your physiology.

Free. Under two minutes. No account needed. You'll get a personalised hourly sodium target, fluid plan, and capsule schedule based on your weight, sweat rate, and race conditions.
