ZERO is HIGH5's everyday hydration tablet, made for anyone who sweats. Each tube contains 20 tablets — drop one into 750ml of water and you've got a light, lightly fizzy drink with the five key electrolytes lost in sweat: sodium, potassium, magnesium, calcium and chloride.

Zero calories, zero sugar and no artificial colours — just clean hydration that's easy to drink all day, on the bike, on a run or at your desk.

Made in Scotland and Informed Sport approved, so you can trust what's in every tablet.
