The science
How do Electrolytes work?
It’s more than just drinking water
Why hydration matters
Your body needs water to function, but hydration depends on more than intake—it’s about how well cells absorb and retain that water.
Your body’s electrical current
Meet the Electrolytes
Electrolytes are minerals that carry a charge in water. They control nerve signals, muscle contractions, and help balance fluids across all cells.
Five electrolytes, countless jobs
The Big Five
Sodium, potassium, chloride, magnesium, and calcium are your key electrolytes—each with distinct roles in hydration, energy, muscle control, and cellular health.
The hydration gatekeeper
Sodium starts it
Sodium draws water into the bloodstream. As it enters cells, water follows, hydrating tissues and helping regulate blood volume and pressure.
Inside-out hydration
Potassium balances things
Potassium works in opposition to sodium, exiting cells as sodium enters. This balance drives water movement and powers nerve and muscle activity.
The perfect counterbalance
Chloride keeps the charge
Chloride partners with sodium to maintain electrical neutrality and support acid-base balance, vital for cell function and hydration stability.
Powering cellular hydration
The Sodium-Potassium pump
This pump pushes sodium out and pulls potassium in—resetting the balance and ensuring water is absorbed exactly where it’s needed.
Fuel for every cell
Magnesium ignites energy
Magnesium helps convert food into cellular energy and keeps the sodium-potassium pump working efficiently. Low magnesium? Hydration and energy both suffer.
Move, contract, repeat
Calcium controls muscles
Calcium triggers muscle contractions and nerve signals, including your heartbeat. Without it, hydration alone won’t power physical performance or recovery.
Too little too late
Why balance is key
Even a small depletion in electrolytes can cause fatigue, cramps, or brain fog. It’s not just hydration—it’s precision fluid management.
Hydration for every occasion
With delicious, refreshing flavours, Zooki Electrolytes+ transforms hydration into a simple, enjoyable, and effective part of your daily routine.
Simply mix a sachet with 500-1000ml of water and feel the benefits fast.

Zooki in the press
"Absorption is optimised"
"A world first"
"Recommended by the pharmacists to the Royal Family"
Each product in the Electrolyte+ Range contains an optimised blend of sodium, calcium, magnesium, chloride and potassium, in addition to extra ingredients to support targeted health benefits. For specific nutritional information on each product, click the 'ingredients and info' section at the top of the page.
Can I have an Electrolyte+ sachet every day?
Yes, all of our Electrolyte+ products can be enjoyed daily.
Is the Electrolyte+ Range vegan?
Yes, all Zooki Electrolyte+ products are vegan.
Can I take multiple Electrolyte+ products in the same day?
We recommend aligning your electrolyte intake with your activity levels and dietary salt consumption. Research suggests that consuming 4-6g of sodium, 4-5g of potassium and 400-600mg of Mg per day is optimal. Most people should only require one Hydration+ sachet per day, however those engaging in extreme physical activity that results in large fluid and electrolyte loss may require more.
What's the best time of day to take it?
This product can be enjoyed at any time of day, whenever is most convenient for you. Your body is naturally dehydrated when you first wake up in the morning due to hours without water, so we recommend early in the morning to start your day hydrated.
