WATERFAST Monk Fruit Keto Electrolyte Powder - Fasting Hydration

Our review of WATERFAST finds it best suited for people doing extended water fasts who need a sugar free electrolyte solution that tastes pleasant enough to help them hydrate. The single biggest reason to try this product is its formulation: measured amounts of sodium, potassium, magnesium and calcium designed specifically to support activity and reduce headache and appetite symptoms during fasting. The Strawberry Watermelon flavor with monk fruit sweetener makes sipping more enjoyable, which can make a real difference when sustained hydration is essential.

Key Features

• Fasting-focused electrolyte balance: Formulated with 1000mg sodium, 1000mg potassium, 100mg magnesium and 420mg calcium per serving to support longer fasts and maintain energy.
• Sugar free sweetness: Monk fruit provides pleasant flavor without added sugar so the drink remains keto-friendly and does not break a fast.
• Palatable flavor: Natural Strawberry Watermelon flavor encourages increased water intake, which helps avoid dehydration during fasting.
• High quality ingredients: Uses Pink Himalayan sea salt, potassium chloride, magnesium malate and calcium citrate for better absorption and fewer digestive side effects.
• USA made and allergen tested: Manufactured in the United States and tested to be gluten-free and soy-free for use.

Who It's For

This product is aimed at people practicing longer water fasts, intermittent fasters who want to extend fasting windows, and keto dieters who need electrolytes without carbs or sugar. Anyone who experiences headaches, low energy, or strong hunger pangs during multi-day fasts may find this powder helpful because the electrolyte profile is set to reduce common fasting side effects.

People who prefer unflavored electrolyte waters or who need very minimal sodium may want to look elsewhere, and those with specific medical conditions should consult a clinician before using a concentrated electrolyte product. Beginners should start with shorter fasts and use the powder gradually to assess tolerance.
