Goji Berry Powder
Also known as: Lycium chinense, Wolfberry, Chinese wolfberry, Goji
Goji berries are nutrient-dense dried fruits traditionally used in Chinese medicine, containing polysaccharides, carotenoids, and antioxidants. Limited clinical evidence exists for most marketed health claims, though observational studies suggest potential benefits for eye health and immune function.

Evidence notes
Most claims lack robust RCT evidence. Traditional use and preliminary in vitro/animal studies support antioxidant potential, but human clinical trials are limited and often small. Eye health claims (zeaxanthin content) are plausible but not definitively proven in humans.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
