Goji berries (Lycium barbarum and Lycium chinense) are widely recognized as functional foods owing to their rich nutritional composition and diverse range of bioactive phytochemicals. This review summarizes the current knowledge on their macro- and micronutrients, polysaccharides, phenolics, carotenoids, vitamins, fatty acids, and other bioactive compounds, highlighting their roles as functional foods and nutraceuticals. These bioactive constituents possess antioxidants and anti-inflammatory activities that may contribute to health promotion and improve dietary quality of life. Recent advances in food processing and applications in bakery, dairy, beverage, snack, and natural preservative formulations are critically evaluated in this review. The effects of cultivation practices, pesticide residues, and post-harvest processing on phytochemical stability, product quality, and safety are also discussed. Future research should prioritize bioavailability, processing stability, clinical validation, and standardization to maximize the nutritional, functional, and commercial potential of goji berry-based products.
