Electrolyte Powder for Fasting

Why electrolytes matter during a fast

When you fast, your body shifts into a different metabolic state. One major change is a drop in insulin, which triggers your kidneys to flush out sodium and water. That’s why many people feel lightheaded, crampy or foggy in the early stages of fasting. It’s not just the hunger; it’s the electrolyte drop.

Water alone won’t fix this. While drinking enough is important, staying properly hydrated means maintaining the right balance of electrolytes like sodium, potassium and magnesium. Without it, you’re more likely to experience symptoms like:

• Dizziness or fatigue
• Muscle cramps
• Headaches
• Brain fog or low mood

Our formula is built to support fasted hydration, giving your body what it actually needs to feel balanced without interfering with your goals.

What makes Sodii the best electrolyte for fasting

Sodii delivers 1000mg of sodium, 210mg of potassium and 70mg of magnesium per serve, designed to work together to support hydration, energy production and nerve function, without interrupting your fast. Our Unflavoured blend contains zero sugar, zero carbs and zero calories. Most of our flavoured options stay under 3 calories per serve, keeping you well below the common fasting threshold (50 calories) while still tasting great.

Our sodium comes from an ancient salt lake in Western Australia's Lake Deborah. It’s naturally mineral-rich, independently tested for heavy metals and pollutants, and processed using seasonal evaporation rather than mining or desalination.

In other words, Sodii has your back!

Flavours that keep you satisfied 

Our naturally flavoured sachets use real fruit oils with organic stevia to create deliciously salty-sweet flavour profiles that make the wait for food a lot more bearable. Choose from options like Salty Kiwi, Salty Pineapple, and Salty Mandarin, or go for Unflavoured if you prefer it plain (and completely calorie-free).

Plus, all blends are HASTA™ certified and free from artificial colours, fillers and carbohydrate powders.
