A typical medium orange contains about 70–85 mg of vitamin C, which is close to or slightly under 100% of the daily recommended amount for most adults.

Quick Scoop: How much vitamin C in an orange?

For everyday eating, you can think of it like this:

  • One medium orange : usually analyzed between about 68 mg and 83 mg of vitamin C.
  • In terms of daily needs: that’s roughly 75–95% of the typical adult daily recommendation (around 75–90 mg per day).
  • In nutrition labels, this is often shown as “around 90–100% Daily Value” for vitamin C per orange.

The exact number changes a bit with:

  • Size of the orange (small vs medium vs large).
  • Variety and growing conditions.
  • How fresh and ripe it is, and how it’s stored.

But if you eat one decent-sized orange, you’re basically getting around a full day’s worth of vitamin C on its own.

Orange vs orange juice

  • 1 medium whole orange: roughly 68–83 mg vitamin C.
  • About ¾ cup orange juice: often around 90+ mg vitamin C, so slightly more concentrated.

Whole fruit still wins on fiber and feeling full, even if juice can edge ahead on vitamin C per serving.

Why this matters now

Vitamin C remains a popular “immune-support” nutrient, especially in winter and cold/flu season, and oranges are still one of the most common, accessible sources people reach for. You don’t need megadoses or supplements to hit your daily target—one orange plus a generally varied diet is usually enough for most healthy adults.

TL;DR: One medium orange gives roughly 70–85 mg of vitamin C, which is close to or about your entire daily vitamin C requirement in a single fruit.
