Stop choosing between fuel and your stomach.
Mid-effort gels and drinks can help the legs, then punish the gut. Swish gives athletes a carbohydrate signal through the mouth — without adding volume to digest.
Use it when the race turns hard, the stomach feels full, or you want the ritual of fueling without swallowing more.
How buyers use it.
A simple three-step ritual for training blocks, race days, and late-session surges.
01
Swish
Rinse the carbohydrate solution around the mouth before a key effort.
02
Spit
Spit it out instead of adding more fluid or gel to the gut.
03
Sprint
Let the mouth-brain signal support focus when the pace lifts.
MOUTH RINSE SCIENCE
A familiar sports-science mechanic, packaged for race day.
8 INGREDIENTS
Clear ingredients, no proprietary blend language for you to decode.
Best suited to sessions where athletes want a fast cue without relying on digestion.
Oral carbohydrate receptors are linked to reward and motor-control pathways involved in effort.
Because Swish is spat out, the ritual avoids adding meaningful stomach volume.
