Goji berries are a good source of vitamins and minerals, such as vitamin C, fiber, iron, vitamin A, zinc and antioxidants. These berries contain all 8 essential amino acids which are valine, isoleucine, leucine, phenylalanine, threonine, tryptophan, methionine, and lysine. Valine is used as an energy source by muscle tissue and isoleucine maintains normal blood sugar. Meanwhile, leucine promotes bone, skin and muscle tissue healing and phenylalanine helps in memory and suppress appetite. In addition, threonine helps to protect liver and tryptophan stabilize moods and helps migraine sufferers. Lastly, methionine eliminate harmful toxins and lysine helps calcium absorption. Besides, 110g of serving (approximately 1/2 a measuring cup) provides nearly 10 percent of your daily value for protein. For fruit, this is a surprising amount of protein. The carbohydrates in goji berries are also complex carbs. This means your blood sugar will increase slowly and reduce your risk of a sugar crash afterwards.
