Rest assured that our Multivitamins and Multiminerals are still viable after being exposed to high heat or cold temperatures. In fact, our vitamins go through quality-control testing, where batch samples are exposed to high and cold temperatures to ensure their continued viability.
If you are concerned about your vitamins being delivered during weather extremes, here are some precautions you could take: 1) expedite your order and make certain to be home to receive the order, 2) ship to your place of work or 3) order multiple bottles at once to avoid receiving your orders during the hot or cold seasons.
Keep in mind, though, that your Multivitamins and Multiminerals need to be refrigerated after opening. Testing has been done on the multivitamins and the multiminerals to determine how long they can be left out after opening; they are good for 7 days out of the refrigerator. We like to err on the side of caution and say 5 days!
