Shipping Information

We provide same day shipping for all orders placed before 4:00 P.M. Central Time. We ship using USPS Priority Mail so your order will arrive as quickly as possible. Typically, shipments arrive within 2 - 3 days. During the holiday season, postal carriers see a massive increase in volume which may lead to delays. We provide tracking information for all accounts that have an associated email address so you can keep tabs on when your supplements are scheduled to arrive. If you do not see this email, check your spam folder. If you wish to have your order shipped via UPS, please call Customer Service to place your order. Additional charges may apply.

Packaging and Shelf Life:

Probiotics are alive and require refrigeration for optimum stability and shelf-life. Our probiotics remain stable due to our Totally Inert Packaging (TIP): the capsules are packaged in double-sealed, amber glass bottles containing rayon wadding and both moisture and oxygen absorption packets. They can be held at temperatures up to 75° F for up to one month (while traveling) but must be kept refrigerated beyond that to assure potency through the expiration date.

We do not ship with any form of ice pack because of our TIP and the fact that ambient humidity created from condensation by a melting ice pack can cause more harm to the probiotics than high temperatures.

We do regular stability testing, including accelerated heat testing to make sure our products will be over the guaranteed potency regardless of temperature. If you are still concerned about summer months, we encourage our customers to take advantage of our volume discounts and order larger amounts in the spring or winter.

International Shipping:

We ship all orders via United States Postal Service; normal transit times are between 10-14 days. USPS Express can be requested for an additional surcharge.
