Can You Drink Electrolyte Powder While Fasting?

You’re fasting. You’re focused. You’re… a little dizzy.

Whether it’s intermittent fasting, 24-hour resets, or “I forgot to eat lunch again,” one thing’s true: your body still needs electrolytes. But here’s where it gets tricky:

Can you use electrolyte powders during a fast? And what about the ones that aren’t zero-calorie — like Mizu Lab electrolytes?

Let’s clear it up.

Electrolytes During Fasting: A Quick Science Break

Even when you’re not eating, you’re still sweating, peeing, and thinking (hopefully) — all of which require minerals like:

Sodium
Potassium
Calcium

Lose too much of them? Cue the headaches, brain fog, and low energy.

But Will Electrolyte Powder Break My Fast?

Here’s the honest answer:

If you’re doing a strict zero-calorie fast for autophagy or ketosis, then yes, even 10 calories technically break that.
If you’re fasting for energy, productivity, or appetite control, a low-calorie electrolyte like Mizu Lab will probably help more than hurt.

It won’t spike your blood sugar. It won’t send your metabolism spiraling. But it might save your mood.

Mizu Lab = Flavorful Fasting Support

Unlike chalky sports drinks or sugary hydration tabs, Mizu Lab was made for flavor without the crash. Our Asian-inspired electrolytes are powered by:

Lychee & Mangosteen
Shine Muscat & Aloe
Asian Yogurt Drink & Strawberry
Passion Fruit & Green Plum

Each stick pack has over 1000mg of electrolytes and vitamins, no added sugar, and only a small amount of calories — just enough to keep you hydrated, not derail your routine.

Fasting Pro Tip:

Low energy during a fast? It’s not always hunger — it’s often electrolyte imbalance. Mizu Lab helps you hydrate with purpose (and great taste) without needing to “break” for a meal.
