Our regular means of shipping is UPS ground or Priority Mail. Most Orders ship the Same Day.

PLEASE BE ADVISED: Though USPS Priority Mail may state "2-day Delivery," the US Postal Service does not guarantee the 2-day timeframe. Therefore, it is not advisable to use this shipping method for probiotics, especially during periods of warm weather.

For additional options or for help in deciding how to ship your order, please call our customer service department at 800.245.8282 (toll free) or 503.694.1600 (international and local callers).
