Common questions
FAQ
Why do I need electrolytes on keto?
Keto causes your kidneys to excrete more sodium and water. This electrolyte loss causes the 'keto flu' — headaches, fatigue, cramps. Replacing sodium, potassium, and magnesium prevents these symptoms.
How much sodium do I need on keto?
Most experts recommend 3,000-5,000mg of sodium daily on keto, significantly more than the standard diet. LMNT provides 1000mg per packet.
Will electrolytes break my fast?
Zero-calorie, zero-sugar electrolyte powders like LMNT and Nuun do not break a fast. Avoid any with sugar, maltodextrin, or calories.
