Sparkling Hydration With Zero Sugar, Zero Calories and a Proper Electrolyte Hit.
 
Hydration that actually tastes like something you'd want to drink.

Cadence packs 500mg sodium, 190mg potassium and 30mg magnesium into a light, crisp, carbonated can - the three electrolytes you lose through sweat. No sugar, no carbs, no caffeine and just 21kJ per 330ml.

Most electrolyte drinks are either a sugar bomb or a powder you have to remember to mix. 

Cadence is neither. Crack one cold before training, sip it through a session, or reach for it the morning after - the carbonation is light enough to drink fast without feeling heavy.
 
Where it 'Hits Different:'
    A full 500mg of sodium per can - not the token amount most sports drinks give you.
    Zero sugar, zero carbs and caffeine-free
    Sparkling, not flat - light fizz that's refreshing without being overpowering.
    Vegan, gluten free, dairy free

Key Ingredients:
    Cadence Core Electrolytes (Sodium Citrate, Magnesium Citrate, Potassium Citrate) - supports fluid balance and normal muscle function.
    Steviol Glycosides - naturally derived sweetener, zero sugar.
    Natural flavours

Servings per package: 1 · Serving size: 330 mL

Potassium is 190 mg, confirmed. That settles the conflict I flagged — the 270 mg figure is from Cadence's UK marketing tiles, not the AU can. Your draft description is correct as written.
