Match-play sweat studies show tennis players lose more sodium and potassium than athletes in continuous sports.

Our formula mirrors that higher sodium-to-potassium ratio, adds buffered citrate to control muscle pH during stop-and-go rallies, and keeps osmolality low so fluid clears the stomach fast. Result: Quick absorption without the sloshy stomach.

Shake or stir one sachet with 16+ oz cold water until dissolved.

Start with one in the morning for daily hydration. Add a second before or during tennis, training, or on hot days when you're sweating more.

• Higher sodium and buffered citrate for stop-start sports
• Lower osmolality for faster gastric emptying
• No added sugar or fillers

Yes.

No sugar, no maltodextrin.

Sweetness comes from stevia and allulose, so you get stable blood glucose and no mid-set crash.

No. Every batch is produced in a cGMP facility and screened against the WADA and USADA Prohibited List. ATP and WTA physios already use it with tested athletes.

Definitely. The mineral levels meet IOC guidelines for youth sport hydration.
