Overview

Goji berries, also known as wolfberries, are small, red berries that have been used in traditional Chinese medicine for over 2,000 years. They are native to Asia and are grown on a shrub called Lycium barbarum. Goji berries are packed with nutrients, including antioxidants, vitamins, and minerals. They are a particularly good source of vitamin C, vitamin A, iron, and selenium. The antioxidants in goji berries, such as zeaxanthin and polysaccharides, help to protect the body from damage caused by free radicals. This may help to reduce the risk of chronic diseases, such as heart disease and cancer, and slow down the aging process. Goji berries are also thought to have immune-boosting, anti-inflammatory, and vision-protective effects. Some research suggests that they may also help to improve mood, energy levels, and athletic performance. Goji berries can be eaten fresh, dried, or cooked. They are also available as a juice, powder, or supplement. While goji berries are generally safe for most people, they can interact with certain medications, so it is important to talk to a doctor before eating large amounts of them.
