Vitamin C in Fresh Orange Juice: How Much and What It Does
A glass of fresh orange juice is a good source of vitamin C. See the numbers, what vitamin C does for the body, and why freshly squeezed juice matters.
Ask anyone what orange juice is good for and the answer is usually the same: vitamin C. That reputation is deserved, and it is also easy to exaggerate. This article gives you the numbers, what vitamin C actually does, and where the honest limits are.
How much vitamin C is in orange juice?
According to the USDA's FoodData Central, raw orange juice contains about 50 mg of vitamin C per 100 ml. A 200 ml serving therefore has roughly 100 mg.
For comparison, the ICMR-NIN's 2020 recommended dietary allowances for Indian adults are about 80 mg of vitamin C a day for men and 65 mg for women. One glass of fresh orange juice can cover a large part of that, or all of it.
These are reference values for orange juice in general. The vitamin C in any one glass depends on the variety of orange, how ripe it was and how long the juice stood before it was drunk. We have not lab-tested our juice for this article, so treat the figure as a guide rather than a label.
What vitamin C does in the body
Humans cannot make vitamin C and cannot store much of it, so it has to come from food regularly. It is involved in several everyday jobs:
- Building collagen, the protein that holds skin, blood vessels and other tissues together.
- Helping the body absorb iron from plant foods such as lentils, spinach and beans.
- Acting as an antioxidant, protecting cells from damage by unstable molecules called free radicals.
- Supporting the normal function of the immune system. Vitamin C is one of the nutrients the immune system needs to work normally.
That last point is where claims often run ahead of the evidence. Vitamin C is needed for normal immune function, but no food or drink prevents or cures infections. Think of it as part of a normal, varied diet, not a shield.
Why fresh matters
Vitamin C is fragile. Air, light, heat and time all break it down. Juice that is squeezed, stored, transported and shelved loses some of it before you drink it, and some packaged juices have vitamin C added back during manufacturing.
A Squeeze Station machine keeps whole oranges refrigerated and squeezes 2-3 of them only when you order. Nothing is stored as juice, so there is no shelf time to lose it in. Read more about how the machine works.
Other good sources
Orange juice is not the only way to get vitamin C, and variety is good. Amla (Indian gooseberry) and guava are richer sources by weight, and lemons, bell peppers, tomatoes and papaya all contribute. A glass of orange juice is a convenient, enjoyable top-up, not the only route.
A note on sugar and balance
Fresh orange juice also contains natural sugar, which we cover in detail in what "no added sugar" really means. One glass fits into most diets; it just should not replace water or whole fruit. If you have a medical condition or follow a restricted diet, ask your doctor or dietitian what suits you.
