When you receive your order, the cool packs may no longer be cool to the touch, but don’t worry; even if the cool packs feel warm, your Evivo is safe to use.  Each sachet of Evivo is specially packed and sealed in an airtight sachet that protects the live bacteria by keeping out air, moisture, and light.   We formulate the product to withstand temperature fluctuations associated with shipping delays to maintain 8 billion CFUs (Colony Forming Units) by the best by date on your package.  

Our recommendation for freezer and fridge storage is intended to ensure the product maintains at least 8 billion CFUs of the beneficial bacteria up to the best by date on your package. We suggest you place the product you receive in the freezer and use 1 sachet per day straight from the freezer. You can store Evivo in the refrigerator for 1 month, but it will last much longer in the freezer – up to the best by date on your package.
