Calories in Orange Juice: Full Nutrition Breakdown

Orange juice is one of the most popular breakfast beverages worldwide, valued for its refreshing taste and impressive vitamin C content. An 8 oz glass of 100% orange juice (not from concentrate) provides about 112 calories, primarily from natural sugars, along with more than a full day's worth of vitamin C. It also supplies potassium, folate, and thiamin.

Calories by serving size:

While orange juice is nutrient-dense, it is also relatively high in natural sugars and calories compared to whole oranges. A single 8 oz glass contains about 21 grams of sugar with little to no fiber, since the pulp and membranes are largely removed during juicing. Keeping portions moderate — around 4 to 8 oz — is the most effective way to enjoy its nutritional benefits without excessive calorie intake.

Frequently Asked Questions (FAQ)

Is drinking orange juice the same as eating an orange?

Not quite. A medium orange contains about 62 calories and 3.1 grams of fiber, while 8 oz of orange juice has 112 calories and virtually no fiber. The fiber in whole oranges slows sugar absorption, promotes satiety, and supports digestive health. Juice delivers vitamins efficiently but lacks the fiber that makes whole fruit more filling.

How much sugar is in a glass of orange juice?

An 8 oz glass of 100% orange juice contains approximately 21 grams of natural sugar, which is comparable to the sugar content in many soft drinks. However, unlike soda, orange juice provides substantial amounts of vitamin C, potassium, and folate. Keeping your serving to 4 to 8 oz helps manage sugar intake while still getting the nutritional benefits.

Is orange juice healthy?

Orange juice is a concentrated source of vitamin C, potassium, and folate, making it nutritious in moderation. However, it is calorie-dense and easy to over-consume because it lacks the fiber of whole fruit. Most dietitians recommend limiting juice to one small glass per day and prioritizing whole oranges when possible.

Is there a difference between fresh-squeezed and store-bought orange juice?

Fresh-squeezed orange juice and store-bought 100% juice have very similar calorie and macronutrient profiles — about 112 calories per 8 oz. The main differences are in taste and processing. Fresh-squeezed juice retains more volatile flavor compounds, while pasteurized store-bought juice has a longer shelf life and may have slightly lower levels of certain heat-sensitive nutrients like vitamin C.

Does calcium-fortified orange juice compare to milk?

Calcium-fortified orange juice typically provides about 350 mg of calcium per 8 oz serving, which is comparable to the 300 mg found in a cup of milk. It can be a useful alternative for people who are lactose intolerant or avoid dairy. However, milk also provides protein, vitamin D, and other nutrients that juice does not, so fortified OJ should complement rather than fully replace dairy in most diets.
