Guidelines for custom diet order changes during COVID-19

    To make one of these changes to an existing order, please contact us either by email at or by phone, 800-483-5523. Remember, our customer service team is always happy to work with you to find the best solution for your needs. These include:

    Ship To address changes:
    Contact customer service at least three business days prior to the scheduled ship date, which can be found on your order acknowledgement.

    Requests to delay shipment:
    Contact customer service at least five business days prior to the scheduled ship date, and we will move the ship date up to 30 days past the original ship date. In the case that your diet has already been produced, we will store it for a similar period of time (depending on order quantity). If we cannot store it for you, we will contact you regarding alternate shipment options.

    Cancel an order:
    For non-irradiated orders, contact customer service at least five business days prior to the scheduled ship date. For orders with irradiation, contact customer service at least ten business days prior to the scheduled ship date.

    Our in-stock diets are processed quickly. Please contact us immediately to discuss options. (Stock diets include TD.88137, TD.06414, TD.01306, and select Tamoxifen diets).
