FREE Cold Pack Service
This heat-sensitive product is stored in a refrigerated section of our warehouse to ensure quality and potency and is shipped within Styrofoam packaging with an ice pack to prevent the product's temperature from exceeding 100 degrees Fahrenheit. It is normal for the ice pack to melt during transit and this will not compromise the efficacy of the probiotic, which laboratory testing has revealed to remain viable after three months at room temperature. However, as an added precaution to avoid exposure to the elements that could occur from idle periods on delivery vehicles, this product is only shipped Mondays, Tuesdays and Wednesdays and Vitacost STRONGLY suggests that you select Next-Day Air shipping service to further minimize the possibility of warming. If you purchase this item outside of this time period, it will be shipped the following Monday. This product cannot be shipped internationally. Refrigerate upon receipt.
