Goji berry is a fruit that's used in Traditional Chinese Medicine to support liver health. Science is confirming that many of the benefits of goji berry may be due to its high levels of flavanols, polysaccharides, and carotenoids like zeaxanthin and beta-carotene. Supplementing with zeaxanthin may be associated with improved skin hydration and reduced appearance of wrinkles and fine lines. Research suggests that taking beta-carotene may be associated with reduced wrinkles and a more healthy response to UV light. Goji is being studied for its antioxidant benefits and potential to protect against cell damage related to UV exposure.
