Shipping is FREE anywhere in the continental U.S. for all orders over $50! For orders $50 and under, we charge a flat rate of $5.00. We ship orders Monday through Saturday.

Our goal is to get products in your hands fast. Once you place your order, we will process it and get it out to you as soon as possible. We usually ship the same day your order was placed, or the next business day (M-F), except for extra-perishable items that might spoil if left on a delivery truck for extended periods of time. In cases like these, if you place an order for a perishable product on a Thursday or Friday, we would wait until Monday to send it. Your order will typically arrive within two to five (2-5) business days after it is placed. You will receive an e-mail notification after you place your order and again when your order has shipped.

International Shipping: some products, such as probiotics, we can’t ship internationally due to a scanning procedure that kills the bacteria in the probiotic, rendering it useless. Please contact our customer support team at and provide the specific products you would like to purchase and your mailing address. We will do our best to fulfill your order, and we’ll provide an estimated shipping cost specifically for you.
