What is the shelf life for the sticks?Updated 3 months ago

Third Wave Water minerals will not expire or go bad. 

Each stick and box has a “Manufactured On" date that shows when the sticks were made and packaged.

To ensure the longest life possible, make sure to store the mineral sticks at room temperature and out of direct sunlight or refrigerate if you live in hot or humid environments. When exposed to excess heat and humidity, the minerals may begin to clump up and take a little longer to dissolve.
