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.

Review topics: [taste, electrolytes, sachets].
"I ordered the Daily Hydration Sachets and they arrived quickly. They taste great and I can mix the electrolytes with my creatine to get the best performance for my running, rowing and weight training. Highly recommended!"
"Tastes great, the electrolytes are amazing have taken them everyday, the sachets are great and handy for on the go or at home."
"Great flavour and great summer drink, sachets are easy to open and 30 pack per order is ideal for the month"
"Taste great and mix well. The sachets are convenient for daily use when on the move, but sometimes can be difficult to tear open. The electrolyte mix can sometimes stick together/ be difficult to empty out of sachet. Overall - great product, supports my training well"
"I love these - please make them for energy as well. The grapefruit can get too sickly sometimes!"
"This is my go to flavour when it comes to daily hydration. Top tier 👌🏾"
"Great tasting product, though the packaging has become tougher to rip open especially with wet hands (when you're in a rush filling a bottle). Often find myself using scissors which is a very minor gripe."
"excellent and the best on the market."
"The taste is amazing! So easy to travel with too. My favourite electrolytes and I have tried many!"
"Favourite flavour of the sachets, easy to use and have a few in my gym bag. Now the weather is warmer, find the benefits of using electrolytes even more noticeable and cadence are the best I’ve used."
