Kefir Lab is not responsible for any shipping delays caused by the shipping carrier, weather, or other circumstances beyond our control. However, we will do our best to keep you informed of any delays and work with the shipping carrier to resolve any issues.

If a package is lost, missing or damaged, please get in touch with us immediately at hello@kefirlab.com. We will work with the shipping carrier to locate the package and resolve the issue.

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.

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.

We constantly look for ways to be a better business for the world we are living in.

Hence, we made a tough decision to switch from glass bottles to BPA – Free and Highly Recyclable PET1 plastic bottles. We want to be fully transparent with our customers and share all our major decisions.

While it was ideal at the smaller scale, back when we started at farmers markets and local stores in the Bay Area, it wasn't as effective and sustainable when we scaled.

Producing, transporting and recycling glass is CO2 intensive. In addition, the enormous amounts of hot water waste to sanitize bottles before use wasn't at all sustainable for the citizens of beautiful California, where the water is scarce.

Because we are perfectionists, when it comes to health we have absolutely no compromises. That is why we switched to special IMS Dairy Certified Bottles which account to only 10% of all PET1 bottles on the market. These are made special for dairy use and are certified not to leach any chemicals. We made sure you won't feel any difference vs. glass (except for the lighter grocery bag and lower price!).

We believe in saving the water and carbon emissions and encouraging our Probiotic Fans to recycle the bottles.
