How to use Lytework in training
-
1 Drink for fluid
Water as normal. Hydrate for thirst + conditions.
-
2 Dose for sodium
Lytework on schedule. Not based on flavour.
-
3 Start early
Take your first capsule before you feel you need it
-
4 Adjust
More for heat, long sessions, heavy sweat.
The system difference
Not a drink. A dosing system.
Most hydration products bundle sodium with flavour, sugar, and fixed doses. Lytework separates sodium from fluid so you can dose precisely — based on conditions, not guesswork.
| Criteria |
Lytework
|
Electrolyte drinks
|
|---|---|---|
| Sodium precision |
Dose adjusts to the athlete, session, heat load, and sweat rate.
|
Fixed per serve. Harder to personalise without changing total volume.
|
| Flexibility |
Sodium separated from fluid. Adjust each independently.
|
Sodium and fluid bundled together — adjust one, you adjust both.
|
| Flavour fatigue |
No flavour. Easier across long sessions and repeated use.
|
Flavour becomes difficult over time, especially in heat or multi-hour efforts.
|
| Portability |
Compact capsules. Pocket-sized. No mixing required.
|
Bottles, sachets, or powders add bulk and preparation time.
|
| System simplicity |
Works alongside your existing fuel and fluid setup. Nothing to replace.
|
Can force combining hydration, sodium, flavour, and fuel into one product.

Who it's for
Lytework is for...
-
Endurance athletes
Triathletes, runners, cyclists & Hyrox athletes who need performance hydration without sugar or flavour.
-
Heavy sweaters and heat trainers
Individuals exposed to heat stress through training, sauna use, or naturally elevated sweat sodium loss.
Tested in training, racing, and heat.
Every result below is from an athlete using Lytework in real conditions. No lab settings, no incentivised reviews. Protocol data included.
So much easier than having to down electrolytes — and way easier to keep track of.
I stopped cramping mid-race for the first time. The ability to dose based on conditions rather than a fixed serve size changed everything.
No flavour fatigue is a real thing. After 3 hours of training I could still take these without any issue — something I couldn't do with electrolyte drinks.
Simple product. I carry a few capsules and adjust based on how hot the day is. It fits into my existing setup without changing anything else.
Took my salt tabs during the ride and felt way better almost immediately. Simple change but it made a big difference.
Zero GI issues and easy to use mid-session. Simple product, but a big upgrade for performance and consistency.
Capsules have definitely helped — only a couple sessions in and already noticing the difference.
Field testing is ongoing. Every athlete uses a personalised protocol calculated from their sweat rate, session length, and conditions. Every athlete in our field testing program uses a personalised protocol.
