Shipping Procedures
We take extra measures to ensure your order arrives in its best condition. That means we send Kefir Lab in a temperature-controlled package so it remains at a refrigerated-like state until it arrives at your door.
Shipping Temperature
Fermentation is a natural way of preserving food. Just like other highly probiotic supplements, you find on the market, our 100 Trillion Probiotic Kefirs & Shots do not need to stay cold during transit. That’s also to ensure the potent probiotics would survive through the “warm” digestion tract. Yet, we still like to insulate and add an ice pack in case of shipping delays. The 100 Trillion Probiotic Kefir is safe and delicious no matter what temperature it arrives at.
Shipping Insurance
At checkout, you can easily add our insurance to cover your parcel against loss, theft, or damage. This option ensures quick resolutions within 24 hours for any unforeseen events, providing peace of mind with just one click.
International Shipping
We offer international shipping on our 100 Trillion Probiotic shots to Canada, Australia, the UK, and the EU. The shipping rate is automatically generated upon checkout with FedEx Priority (3-5 business days delivery).
