FAQ

Frequently Asked Questions

Everything you need to know about electrolytes and hydration

Electrolytes are minerals that carry an electric charge and are essential for hydration, nerve function, muscle contraction, and pH balance. The key electrolytes include sodium, potassium, magnesium, calcium, and chloride. When you sweat, exercise intensely, or follow certain diets like keto, you lose electrolytes and need to replenish them to maintain optimal body function.

Common signs of electrolyte imbalance include muscle cramps, fatigue, headaches, dizziness, brain fog, and irregular heartbeat. Keto dieters often experience the 'keto flu' which is largely caused by electrolyte depletion. If you exercise heavily, sweat a lot, or follow a low-carb diet, you're at higher risk and may benefit from an electrolyte supplement.

Electrolyte powders are generally superior to traditional sports drinks because they provide higher concentrations of essential minerals without the excess sugar. Most sports drinks contain only small amounts of electrolytes and are loaded with added sugars. Quality electrolyte powders offer precise dosing, zero sugar options, and better value per serving.

Yes, most electrolyte supplements are safe for daily use. In fact, daily supplementation can be beneficial for people on keto diets, those who exercise regularly, or anyone who doesn't get enough minerals from food alone. However, it's important to follow the recommended serving size and consult with a healthcare provider if you have kidney issues or take blood pressure medication.

The best keto electrolyte powders are sugar-free and high in sodium, potassium, and magnesium — the three minerals most depleted on a ketogenic diet. Our top picks for keto include LMNT (1,000mg sodium per serving) and Dr. Berg's Electrolyte Powder (1,000mg potassium per serving). Check our full keto electrolyte comparison for detailed reviews.
