Dehydrated? That's Because Water Isn't Enough

Your average daily electrolyte loss,

by the numbers:

Sodium: 2275mg
Potassium: 455mg

Magnesium: 22milligrams

Intense exercise can increase electrolyte loss by 2,000 mg/hour.

With up to 7x the electrolytes of leading sports drinks, Mandatory's premium formula, powered by naturally superior Pink Himalayan Sea Salt gives your body & mind everything it needs to perform at your peak.

Try Mandatory

You Read Labels. So Do We.

No sugar. No artificial sweeteners. No harsh additives your body doesn't need.

While most hydration brands cut costs with stripped table salt, we source Pink Himalayan Salt, naturally rich in trace minerals, unrefined, and as far from processed as it gets. Every ingredient earns its place in the formula.

When your mineral profile is right, fluid reaches your muscles instead of just being flushed out. That means with MANDATORY you maintain output when it counts, finish sessions strong, and recover faster when they're done.

Try Mandatory

What makes it Mandatory?

  • Increased & Sustained Energy

    Sugary sports drinks spike your energy and drop. MANDATORY fuels with high-grade minerals so your output stays consistent from warm-up to the end of the session.

  • Stay Sharp

    Dehydration hits your brain & focus before it hits your body. MANDATORY keeps your mineral balance dialled in, so your decision-making stays clear.

  • Faster Muscle Recovery

    Magnesium and potassium reduce muscle fatigue and accelerate repair. So you recover faster & the day after a hard session doesn't cost you the next one.

  • Reduce Fatigue & Headaches

    Post-training headaches aren't inevitable they're a sign of electrolyte loss. Mandatory replaces what you lose through sweat.

  • Natural Ingredients & Flavours

    No artificial colours, flavours, or fillers ever. Every ingredient is natural, functional, and earns its place. If it doesn't serve your performance, it's not in the tub.

  • Hydration That Actually Works.

    Water alone can't reach your muscles without electrolytes to carry it there. MANDATORY's clinical-dose formula absorbs at a cellular level hydrated 3x faster than water. 1 cup is the equivalent to 3Litres of water.
