Goji, or Lycium barbarum, is a bright red berry people dry and eat whole, or turn into juices, powders, and extracts. The fruit packs antioxidants like zeaxanthin and carotenoids.
Traditional use leans on goji for immune function and everyday vitality. Many reach for it to support eye health because of the zeaxanthin. Others view it as a general wellness tonic for energy and stress adaptation. Strong scientific backing for those specific uses is still thin.
People eat the berries by the handful, blend them into smoothies, or brew them as tea. Extracts and concentrated juices are common too. Doses shift a lot by form. Powdered supplements offer a stronger option.
Side effects are rare but can include allergic reactions. Goji may interact with certain drugs, especially blood thinners and diabetes medications. Safety data for pregnancy or breastfeeding is lacking. Moderate food amounts are probably fine, but skip concentrated supplements.
