Sugar-Free Electrolytes
Made in NZ
ZERO Electrolytes
Lemonade
600MG SODIUM · 5 ELECTROLYTES · ZERO SUGAR
Electrolytes dosed for the sessions that ask the most of you. Heavy lifts, hot mornings, back-to-back days. One sachet in 600ml and the salt is handled.
The salt your body runs on, dosed for the sessions that ask the most of you. 600mg of sodium per sachet, with potassium, chloride, magnesium and calcium alongside it.
Zero carries the electrolytes and leaves the carbs to you. Reach for it on heavy lifting days, in summer heat, on back-to-back mornings, and any session where you are fuelling with food and want your bottle to handle the salt.
Lemon. Thirty sachets. One in 600ml and you are away.
Mineral Salts (Magnesium Citrate, Potassium Chloride, Calcium Citrate), New Zealand Sea Salt, Citric Acid, Natural Lemon Flavour, Natural Sweetener (Thaumatin).
That is the whole list. Thaumatin is a sweetener taken from the katemfe fruit, which is how Zero tastes like lemonade with nothing artificial in it.
One sachet in 600ml of water. Shake or stir until it clears.
Hot sessions and heavy days: one sachet an hour while you work.
Lifting: one sachet sipped across the session keeps the salt topped up without sitting heavy.
Waking up: one sachet first thing on a big training day starts you topped up rather than catching up.
Up to 2.5 serves a day.
Per 5.25g sachet, mixed in 600ml water: 24 kJ. Carbohydrate 0.3g, of which sugars 0g.
Sodium 600mg. Chloride 1200mg. Potassium 300mg. Magnesium 100mg. Calcium 80mg.

Why we made it
"They told me I'd never run again. So I did.
KYRO is what that journey built."
Two ACL tears and a year I almost lost. I built KYRO between recovery and the Ironman 70.3 World champs start line. Zero is the one I wanted in my gym bag on lifting days and in my pocket through a Hobsonville summer.
FAQ
The questions worth asking.
Zero when the salt is the job: lifting, hot weather, back-to-back days, or any session where you are eating real food around it. Hydrafuel when the session runs past an hour and you want 30g of carbs in the bottle as well. A lot of people keep both and pick by the session.
It matches what most people lose in an hour of real sweat, and salty sweaters lose more than that. If you finish sessions with white marks on your cap or your kit, this is the dose you have been looking for.
No. The lemon and citric acid balance the salt, and thaumatin rounds it off. It drinks clean and light, which is what makes a second sachet easy on a long day.
A natural sweetener taken from the katemfe fruit, grown in West Africa. It is intensely sweet, so a tiny amount does the job, and it carries no sugar and no artificial aftertaste.
Yes. Up to 2.5 serves a day. On a hot double day, one in the morning and one across the afternoon session works well.
