Goji juice is derived from berries harvested from the Lycium shrub. Although goji juice is marketed for use with many conditions, so far though, there is not enough scientific evidence to determine whether or not it is effective for any of them.

Goji juice is a product known to interact with warfarin. Patients are at increased risk of bleeding when consuming berries from the goji bush.1 Patient responses vary and patients should not consume goji juice without permission from their doctor.1 More frequent testing may be necessary to improve safety on warfarin. As always, consult with your doctor before you start taking or stop taking supplements.
