SULOS
Gels and drinks weren’t built for your gut.
Endurance athletes need fast carbohydrate availability, but ingesting fuel mid-effort can punish the stomach: bloating, nausea, cramps, and that heavy slosh that makes every stride feel expensive.
Sulos is built around the mouth-rinse protocol: trigger the performance signal, then spit it out. You get the race-day ritual without asking your gut to carry the load.
Fuel signal in. Stomach load out.
MOUTH RINSE SCIENCE
Backed by peer-reviewed sports science.
Performance gains have been reported in high-intensity endurance efforts when carbohydrate is rinsed in the mouth without ingestion.
Studies are strongest for sessions around one hour, where central carbohydrate sensing can support pace without requiring gut fuel absorption.
Carbohydrate receptors in the oral cavity appear to activate reward and motor-control regions linked to perceived effort and output.
Because the rinse is spat out, athletes can use the protocol when they want a carbohydrate signal without adding stomach volume.
RITUAL, NOT REFUEL
This is not a drink.
Each 35g stick pack is mixed into 500ml water to create a 6.4% carbohydrate solution designed for rinsing, not swallowing. Use it before key intervals, late-race surges, and sessions where your gut has already had enough.
