There are 110 calories in 8 ounces of orange juice, according to Self Nutrition Data. This value only applies to raw orange juice, and it does not cover orange juice products to which sugar has been added or removed.
Certain orange juice manufactures add or remove sugar in their products, resulting in a different caloric value. Tropicana's Trop50, for instance, has some sugar removed, resulting in a product with only 50 calories. Other orange juices have added sugar, resulting in a product with more than 110 calories.
An 8-ounce serving of raw orange juice also contains many vitamins and minerals, including an average of 207 percent the recommended daily allowance of vitamin C, Self Nutrition Data claims.
