What is it?

The zero-calorie fasting add-on said to prevent headaches, steady energy, and make longer fasts easier.

Claims audit / 02

What does it claim?

Each claim is rated separately. Ingredient evidence does not prove that this finished product produces the same result.

Claim 01 / Sodium, potassium + fluid

Everyone who fasts needs electrolyte supplements for energy and safety.

Limited

Electrolytes are essential, but most healthy people doing short fasts do not automatically need supplements. Needs rise with prolonged fasting, heavy sweating, illness, or certain medications; excess intake can also be harmful.

Evidence review / 03

What does the evidence say?

Evi rates the research behind each claim. Unless an exact-product study is recorded, ingredient findings describe the ingredient—not proof that this finished formula produces the same result.

What we found

  1. 01

    A short overnight fast is not the same as prolonged fasting in heat or during intense exercise.

  2. 02

    More electrolytes are not automatically better, especially with kidney, heart, or blood-pressure conditions.

  3. 03

    Persistent dizziness, weakness, vomiting, or confusion is a reason to stop—not add another scoop.

How the rating was reached

Limited

Evi never assigns numeric scores. The level follows fixed rules from recorded research, so the same evidence always gives the same result.

Independent summary

The Evi Take

Potentially useful in specific high-loss situations, unnecessary as a blanket add-on to every short fast.

An evidence-focused interpretation—not a diagnosis or personalized medical treatment advice.

What changed

  • — Study summary corrected: Sodium, potassium + fluid. A source-by-source audit found the previous summary said more than, or something different from, what the study itself reports. Before and after

Using it / 05

Practical context

A grounded starting point—not personalized medical advice.

Frequency

Treat it as optional and test it gradually rather than making it an all-or-nothing daily rule.

How to approach it

Use the evidence summary above to separate the plausible mechanism from the social-media ritual around electrolyte fasting.

Cautions & costs

Consider personal conditions, medications, dental or sleep risks, and added costs. Ask a qualified clinician when unsure.
