Once the package is opened, yes, Athletic Greens needs to be kept refrigerated. This helps to preserve the integrity and efficacy of the ingredients. 

The hermetic seal of the unopened package protects the contents and prevents the need for refrigeration until the pouch is opened.

Our Athletic Greens Travel Packs are individually sealed servings and therefore do not need to be kept refrigerated making them perfect for travel and when you’re on the go.
