The problem with standard electrolytes during a fast

If you practice intermittent fasting or time-restricted eating, you know that staying hydrated is the secret to making it to your next meal feeling sharp. But most electrolyte supplements on the market actively work against your fasting goals:

  • Hidden Sugars & Sweeteners: Most powders rely on sugar, stevia, or sucralose. Even zero-calorie sweeteners can trigger an insulin response in some people, potentially disrupting your fasted state.
  • The "Flushing" Effect: When you fast, your body naturally depletes its glycogen stores, flushing out a massive amount of water and essential sodium in the process. This drop in electrolytes is what causes that heavy, depleted, "foggy" feeling—often called fasting fatigue.
  • Hard on an Empty Stomach: Chugging a brightly coloured, artificial-tasting sports drink on a completely empty stomach is a recipe for nausea.

That’s why Oshun is different and perfectly respects your fasting window.

Read on to find out why fasting enthusiasts are switching to Oshun.

1. 100% Fast-Friendly (Zero Calories, Zero Sweeteners)

Oshun contains exactly zero calories, zero carbohydrates, and zero artificial or natural sweeteners. It is purely trace minerals and electrolytes. You get the hydration your body is craving without spiking your blood sugar or breaking your fast.

2. Beat the Fasting Slump

When you feel yourself hitting a wall during your fasting window, it is rarely true hunger.

It’s usually dehydration. Four pumps of Oshun deliver 250mg of Sodium alongside Potassium, Chloride, and Magnesium (which contributes to a reduction of tiredness and fatigue). It replenishes exactly what you are flushing out, without a single insulin response.

“I sauna and fast regularly, so I’m really happy to finally find a sugar-free rehydration option. I love the very slight saline taste and convenience of it coming in a liquid concentrate.”

3. Perfect for Black Coffee & Water

Because Oshun is completely unflavoured, it is the ultimate fasting companion. Pump it directly into your morning black coffee, your green tea, or your chilled water. You get all the mineral benefits without altering the taste of your morning brew. And of course, without triggering a digestive response.

4. Precision Dosing

Our pump bottle lets you customize your intake based on your fasting schedule. Doing a standard 16:8? Add 1-2 pumps to your morning water.

Pushing through a longer 24-hour or multi-day fast? Easily increase your pumps throughout the day to keep your electrolytes balanced.

“Have been using this a few months now and it’s amazing, I train fasted most morning so I have 3-4 squirts in a glass of water and then I feel great!”
