Goji berries, also known as wolfberries, are the delicate bright red fruit of the goji shrub, which belongs to the nightshade family and is native to China. Goji berries contain six vitamins, 11 minerals, 18 amino acids and a variety of potentially beneficial phytochemicals. Their health benefits are often grouped into four main categories: antioxidant, immune-boosting, anti-aging and nerve-function benefits.
