Due to the overwhelming demand for deliveries in the US and around the world, as well as modified practices by our shipping partners to keep their workforce and customers safe, customers should anticipate parcel delays for the foreseeable future. USPS and FedEx are responding to unprecedented parcel volumes and have suspended all service guarantees. Therefore, we are unable to give you an accurate estimate of your parcel's arrival date. Please use the provided tracking information to check online for the most up to date information on the shipment. Delays of several days or even weeks are not uncommon at this time. We appreciate your patience and understanding.

We will continue to be here to support you as our customer, before, during, and after the buying & shipping process. However, due to these long and universal delays, we are not able to re-ship orders or flag them for investigation with the same expediency as we were able to prior to the delays associated with the COVID-19 pandemic. Thank you for being our customer, and we appreciate your support more than ever at this time.

STORAGE: Our probiotic formulations must be refrigerated to maintain maximum potency. You can, however, travel with our probiotic supplements unrefrigerated for two to three weeks with minimal bacterial count reduction.

Temperature Stability Data: Below is a graph of a two year temperature stability study that we have conducted at room and refrigerated temperatures. As one can see, at refrigerated temperature the potency loss is negligible. While the loss at room temperature within a few weeks is very low. We can therefore assure you that the quality of our very high potency probiotic dietary supplements will not be compromised. However, we suggest that you refrigerate our probiotic capsules and powders upon receipt, in order to retain their maximum potency up to one year from the date of receipt.

Custom Probiotics capsules and powders are temperature stable for 2-3 weeks.
