Product is non-returnable.
A hard, hot or busy hour drains 500 to 700mg of sodium. Most sachets give you 200 to 300. This closes the gap.
Sodium is the electrolyte you lose most through sweat. It drives fluid absorption and retention, keeps your electrolyte balance steady, and helps your body hold the water you drink instead of passing it straight through. Getting enough is what helps you stay hydrated, hold performance, and avoid the cramps that come with running low.
Potassium works alongside sodium to maintain normal fluid balance, nerve signals and muscle contractions. It also helps balance out sodium, so the two together keep your hydration steady rather than swinging in one direction.
Magnesium supports normal muscle function, the nervous system, and energy production, and contributes to reducing tiredness and fatigue. It helps move water where your body needs it, which matters for muscle function, energy and recovery.

500mg sodium, 200mg potassium, 20mg magnesium, zero sugar. The electrolytes you lose, dosed to match.
Water replaces the fluid, not the sodium you sweat out. This does both, so you actually stay hydrated instead of just topping up.
First thing to start hydrated, before or during training, or any day you know is going to be a long one.
Mix with about 500ml of still water.
Yes. A lot of people have one in the morning and one around training.

Yes, and free from artificial colours and fillers.
Melonberry's the bestseller. Citrus if you like it sharp, Orange if you want it smooth.

Every batch is tested by trusted global programs including Informed Sport Certified.
Every formula is calibrated to what your body actually loses in sweat, not a generic electrolyte dose.

"Great flavor and perfect electrolyte ratio! Last time I trained for a fall marathon in the summer, I was constantly depleted after runs. I found consuming a sachet a day helps keep my hydration levels topped off to handle the hot summer workouts."
"Purchased the orange and lime daily hydration along with sleep sachets. Amazing taste, no heavy gut feeling that many electrolyte drinks lend. 10/10 will continue subscription."
"I am obsessed with these! I drink them everyday to help stay hydrated during my marathon training."
"I absolutely love this hydration pack! The packaging is gorgeous, and I really appreciate the meaning behind the brand—it feels so intentional and authentic. During my runs—whether long, short, or on hot days—the hydration is perfect. It keeps me going without being too salty. The flavors are amazing—my absolute favorite is melonberry, but orange is also fantastic. Plus, it’s super easy to open and carry—just what I need for a hassle-free run."
"love this sachet! i definitely notice a difference in my performance and recovery and it tastes great"
"Amazing products! Have the daily, sleep, and race hydration. Absolutely love them! Got me through my half marathon!"
"Absolutely love it. By far my new favorite source of electrolytes!!"
"I genuinely love these electrolyte sachets. They’re incredibly easy to open, with no mess or frustration like I’ve experienced with other brands. That alone sets them apart. The taste is outstanding—clean, refreshing, and actually enjoyable to drink. Even my kids love them, which says a lot. What really stands out, though, is Cadence’s commitment to clean ingredients and transparency. You can tell there’s real intention behind the formulation, and that level of trust is hard to find in this space. After trying these, I have zero interest in going back to anything else. Cadence got this right."
"great product, great packaging, great taste, great fuel for daily performance"
"Tastes like orange juice, but better! Great way to start the day!"
