Frequently Asked Questions
What's the difference between expiration and best quality dates for Isotonic Electrolyte Powder?
The expiration date on Isotonic Electrolyte Powder indicates the last day the manufacturer guarantees the full potency and safety of the product. Over time, the electrolytes in the powder may degrade, reducing their effectiveness.

For best quality, use the powder before the expiration date.
How can I tell if Isotonic Electrolyte Powder has gone bad?
If Isotonic Electrolyte Powder has gone bad, you may notice clumping or hardening of the powder, a change in color to a darker shade, or a foul odor. Check for any signs of moisture or mold growth as well. If you observe any of these indicators, it's best to discard the powder to avoid potential health risks.
What are the food safety risks with Isotonic Electrolyte Powder?
Isotonic Electrolyte Powder poses a low risk of foodborne illness due to its dry form that inhibits bacterial growth. However, contamination can occur if moisture enters the container.

What are some pro tips for storing Isotonic Electrolyte Powder?

To maintain freshness, consider transferring smaller portions of the powder into a separate airtight container for daily use while keeping the main supply sealed.
