Hydration is a
performance variable.
Treat it like one.
We exist to give endurance athletes the tools, the science, and the product to manage hydration with the same precision they apply to training, fuelling, and recovery.
Most athletes are hydrating on assumptions — not data.
The endurance sports industry has spent decades improving training methodology, race nutrition, and recovery protocols. Hydration has largely been left behind — still relying on fixed-dose drinks designed for an average athlete that does not exist.
The science is clear. Sodium loss varies up to 10× between individuals. Sweat rates differ by training status, heat, humidity, and genetics. No single electrolyte product can meet the needs of every athlete in every condition. And yet the market continues to sell one.
Lytework exists because precision matters. Not as a marketing claim — as a physiological reality. And because every athlete deserves a hydration strategy built around their body, not a population average.
Variability in sodium loss between athletes completing the same session in the same conditions. Fixed-dose products cannot account for this.
Sodium per Lytework capsule — a precise, scalable dose athletes can adjust based on their sweat rate, session length, and conditions.
Free tools built to help athletes calculate their individual sodium, fluid, and carbohydrate targets before every training session and race.
Three principles that drive every decision we make.
Precision over assumption
We do not build products around average athlete data. We build tools that help each athlete find their own numbers — and a product precise enough to execute them. Guesswork costs performance. Precision doesn't.
Evidence before trend
Every Lytework recommendation is grounded in exercise physiology research, not marketing consensus. We cite our sources. We acknowledge what the science does and doesn't support. We do not overstate claims to sell product.
Function before flavour
We stripped the product back to what the body actually needs. No sugar. No flavour. No fillers. Just a clean, measurable sodium dose that works in any condition — including the conditions where flavoured products stop working.
Standards we hold ourselves to — publicly.
These are not aspirations. They are the operating principles we apply to every product decision, every piece of content, and every claim we make.
Every physiological claim we make links to peer-reviewed research. We do not use research selectively. We acknowledge where evidence is strong and where individual variation applies.
Every athlete testimonial on this site is from real field testing with real protocol data. No free product in exchange for positive reviews. No curated or manufactured social proof.
The calculators, protocols, and guides on this site are free and useful regardless of whether you use Lytework. We earn trust by being genuinely helpful — not by gatekeeping information behind a purchase.
Lytework is a sodium dosing tool. It does not replace fuelling, recovery, or training methodology. We are precise about what it solves and what it doesn't.
Building the hydration intelligence system for endurance sport.
Every athlete who trains seriously deserves a hydration strategy as precise as their training plan. We are building the system that makes that possible.
