Freshly squeezed orange juice naturally contains 50 mg of vitamin C per half-cup serving.
Freshly Squeezed Orange Juice
By definition freshly squeezed orange juice is squeezed directly from the orange and consumed immediately. For an adult woman, drinking four ounces (half cup) of freshly squeezed orange juice provides more than 70% of the recommended daily allowance of vitamin C. Drinking an eight-ounce glass provides 140%.
Store Bought Orange Juice
You don't need to squeeze your own orange juice every day to reap the benefits of vitamin C that oranges provide. Squeezing fresh oranges for juice can be time consuming as well as extremely expensive depending on the time of year. Purchasing store bought orange juice by the carton is still a good way to get vitamin C. As an example, according to the nutrition label on a carton of Tropicana Pure Premium orange juice, an eight-ounce glass supplies 120% of daily nutrition intake of vitamin C based on a 2000-calorie diet.
The Fruit Is Best
Getting your vitamin C from the fruit of an orange is the healthiest way to go. The flesh of an orange contains fiber and much of the vitamin C. The white portion contains flavonoids considered to have antioxidant and anti-inflammatory properties.
