1. Clear "Not a Medical Diagnosis" Statement (FDA/Compliance Requirement)
A prominent notice must be placed at the bottom of the after-sales page: "The electrolyte products sold on this site are sports/daily hydration food supplements and are not intended to diagnose, treat, cure, or prevent any disease (including but not limited to dehydration, hyponatremia, etc.). If you have pre-existing kidney conditions or are on a sodium/potassium-restricted diet prescribed by a physician, please consult your doctor before use. We assume no liability for any electrolyte imbalance resulting from self-administered overconsumption."
2. "Non-Claim" Policy for Taste and Solubility Variations
Tap water mineral content varies by country (hard water vs. soft water), which can affect dissolution speed and taste. The policy must state: "Dissolution rate is influenced by water temperature, water quality, and mixing method; taste preference is subjective. After-sales requests based on perceived 'too salty,' 'not tasty,' or 'slightly astringent' notes will be treated as non-quality-related issues and will not be honored."
