If you are unable to begin your cleanse or drink your juices or smoothies within 3 days of delivery, you are able to freeze your juices for consumption later. We do recommend you unscrew the lids and taking a small sip to account for expansion of juices once they are frozen. When you are ready to enjoy them, simply defrost in a cool bowl of water the night before and pop into them your fridge the next morning, shake them well and enjoy every sip! Please be sure to consume your juices or smoothies within three days of defrosting. And also please be aware that the texture and appearance of the juice or smoothie may change after freezing.
