Kiwi vs Orange: Which Has More Vitamin C?
When people think about vitamin C, oranges are usually one of the first fruits that come to mind. But there is another fruit that deserves a closer look: the kiwi.
So, which has more vitamin C, kiwi or orange?
The answer depends on how you compare them. If we compare the fruits by the same weight, green kiwi contains considerably more vitamin C than orange. USDA nutrition data lists about 92.7 mg of vitamin C per 100 grams of raw green kiwi, compared with about 53.2 mg per 100 grams of raw orange.
That does not mean oranges are a poor source of vitamin C. They are still a nutritious fruit and can contribute meaningfully to your daily vitamin C intake.
In this guide, we will compare kiwi and orange side by side, look at their vitamin C content, fiber, calories, potassium, and other nutrients, and explain what the numbers actually mean when you are choosing between the two.
Red and gold kiwifruit can contain substantially more vitamin C per 100 g than a typical orange, while green kiwifruit also provides a significant amount of vitamin C. The exact amount varies by variety and growing conditions.
QUICK ANSWER
Does Kiwi Have More Vitamin C Than Orange?
Yes. When compared by weight, green kiwi contains more vitamin C than an orange.
| Fruit | Vitamin C per 100 g |
|---|---|
| Green kiwi | 92.7 mg |
| Orange | 53.2 mg |
Based on these values, green kiwi provides roughly 74% more vitamin C per 100 grams than an orange.
That is an important distinction because comparing “one kiwi” with “one orange” can give a different impression. Fruits vary considerably in size, so comparing the same weight gives us a more useful nutritional comparison.

KIWI VS ORANGE: VITAMIN C COMPARISON
Which Has More Vitamin C?
If vitamin C is the main thing you are comparing, kiwi comes out ahead.
According to USDA data, raw green kiwi contains approximately 92.7 mg of vitamin C per 100 g, while raw orange contains approximately 53.2 mg per 100 g.
That means you don’t have to rely only on citrus fruits to get vitamin C from your diet.
Kiwi can be a particularly useful fruit choice if you enjoy its flavor and want to include more vitamin C-rich foods in your meals.
However, nutrition is about more than one vitamin. Orange and kiwi have different nutritional profiles, so the “better” fruit depends on what you are looking for.
Vitamin C Comparison
| Fruit | Vitamin C per 100 g | What this means |
|---|---|---|
| Green kiwifruit | ~93 mg | Excellent source of vitamin C |
| SunGold kiwifruit | ~161 mg | Very high in vitamin C |
| Red kiwifruit | ~189 mg | Particularly high in vitamin C |
| Orange | Varies by variety and source | Good source of vitamin C |
The published values for green, SunGold, and red kiwifruit come from different datasets/analyses, so I would not pretend these are laboratory measurements from one single experiment. That’s an important distinction for a trustworthy nutrition article.
Also, the FDA’s current daily value for vitamin C is 90 mg per day for adults and children age 4+, which gives readers a useful reference point.
WHY COMPARING 100 GRAMS MATTERS
Why Do Nutrition Comparisons Use 100 Grams?
You may have seen different numbers online for kiwi and orange.
That can happen because nutrition information is often reported using different serving sizes.
For example:
- One fruit may be larger than another;
- A source may use a cup rather than grams
- The edible portion may differ;
- Varieties of the same fruit can have different nutrient levels
- Databases can contain different entries and sampling methods.
For that reason, comparing both foods using the same weight gives us a much clearer picture.
For this article, the main comparison uses 100 grams of edible raw fruit.
Using that standard:
Green kiwi: 92.7 mg vitamin C per 100 g
Orange: 53.2 mg vitamin C per 100 g
So, when someone asks, “Which has more vitamin C, kiwi or orange?” the answer is kiwi when comparing equal weights of green kiwi and orange.
GREEN KIWI NUTRITION
What Does Green Kiwi Provide?
Vitamin C is only one part of kiwi’s nutritional profile.
USDA data for raw green kiwi lists approximately:
| Nutrient | Amount per 100 g |
|---|---|
| Calories | 61 kcal |
| Carbohydrates | 14.66 g |
| Dietary fiber | 3.0 g |
| Protein | 1.14 g |
| Fat | 0.52 g |
| Potassium | 312 mg |
| Vitamin C | 92.7 mg |
| Vitamin E | 1.46 mg |
| Vitamin K | 40.3 µg |
| Folate | 25 µg |
These values are for raw green kiwifruit and can vary somewhat depending on the fruit and database entry.
One thing that stands out is the combination of vitamin C and dietary fiber. A 100-gram portion of green kiwi provides about 3 grams of fiber as well as a substantial amount of vitamin C.
Can You Eat Kiwi Skin?
Yes.
Kiwi skin is edible.
Some people enjoy the extra texture, while others find the fuzz unpleasant and prefer to peel the fruit.
If you want to eat the skin, wash the kiwi thoroughly under running water first.
You can also choose varieties with smoother skin if texture is an issue.
There’s no nutritional requirement that says you must eat the skin, either. If you prefer peeled kiwi, that’s perfectly fine.

ORANGE NUTRITION
What Does an Orange Provide?
Oranges have their own nutritional strengths.
For 100 grams of raw orange, USDA data lists approximately:
| Nutrient | Amount per 100 g |
|---|---|
| Calories | 47 kcal |
| Carbohydrates | 11.75 g |
| Dietary fiber | 2.4 g |
| Protein | 0.94 g |
| Fat | 0.12 g |
| Potassium | 181 mg |
| Vitamin C | 53.2 mg |
| Folate | 30 µg |
| Vitamin A | 11 µg RAE |
So although orange contains less vitamin C than green kiwi by weight, it remains a nutritious fruit.
KIWI VS ORANGE: SIDE-BY-SIDE
Nutrition Comparison
Here’s the simple comparison:
| Nutrient per 100 g | Green Kiwi | Orange |
|---|---|---|
| Calories | 61 kcal | 47 kcal |
| Fiber | 3.0 g | 2.4 g |
| Protein | 1.14 g | 0.94 g |
| Potassium | 312 mg | 181 mg |
| Vitamin C | 92.7 mg | 53.2 mg |
| Vitamin E | 1.46 mg | 0.18 mg |
| Vitamin K | 40.3 µg | 0 µg |
| Folate | 25 µg | 30 µg |
What does this comparison tell us?
There isn’t one fruit that wins every category.
Kiwi provides more vitamin C, fiber, potassium, vitamin E, and vitamin K per 100 grams in this comparison.
Orange provides fewer calories per 100 grams and slightly more folate.
So the best choice depends on what you want from your fruit.
Taste and Texture
Nutrition isn’t the only thing that determines which fruit you’ll actually enjoy.
Kiwi
Green kiwi is soft, juicy, and sweet-tart. Its acidity gives it a bright flavor that works particularly well with creamy foods such as yogurt.
Gold kiwi tends to be sweeter and smoother.
Orange
Oranges are juicy, fragrant, and distinctly citrusy. Depending on the variety, they can range from very sweet to pleasantly tart.
If you prefer softer fruit with a sharper flavor, kiwi may win for you.
If you prefer juicy citrus, orange may be the obvious choice.
And there’s nothing wrong with choosing food partly because you actually enjoy eating it.
In fact, that’s probably one of the most practical nutrition rules there is.
WHAT DOES VITAMIN C DO?
Why Is Vitamin C Important?
Vitamin C is an essential water-soluble vitamin.
The body uses vitamin C for several important functions. It is involved in collagen production, helps with iron absorption from plant foods, supports normal immune function, and also acts as an antioxidant.
This is one reason vitamin-C-rich fruits can be a useful part of a balanced diet.
It is worth remembering, though, that eating a particular fruit does not automatically prevent illness or guarantee better health. Overall dietary patterns matter much more than one individual food.
HOW MUCH VITAMIN C DO YOU NEED?
Daily Vitamin C Requirements
For adults, the U.S. National Institutes of Health lists the recommended daily amount as
- Adult men: 90 mg per day
- Adult women: 75 mg per day
- Pregnant women: 85 mg per day
- Breastfeeding women: 120 mg per day
People who smoke need an additional 35 mg per day because smoking increases oxidative stress and vitamin C requirements.
This puts the kiwi-versus-orange comparison into perspective.
A 100-gram portion of green kiwi contains approximately 92.7 mg of vitamin C, while 100 grams of orange contains approximately 53.2 mg.
But remember: a typical serving of fruit is not necessarily exactly 100 grams. Actual intake depends on the size and amount of fruit you eat.
DOES MORE VITAMIN C MEAN KIWI IS ALWAYS BETTER?
Not Necessarily
It is tempting to look at the numbers and simply declare Kiwi the winner.
For vitamin C, kiwi does win this particular comparison.
But that does not make orange a bad choice.
A healthy diet isn’t built around getting the maximum possible amount of one nutrient from every food. Variety matters.
Oranges provide vitamin C, fiber, folate, and other nutrients, while kiwi provides its own combination of vitamins, minerals, and fiber.
If you enjoy oranges, there is no reason to stop eating them simply because kiwi contains more vitamin C.
WHAT ABOUT RED KIWI?
Is Red Kiwi Also Nutritious?
Red kiwi is another interesting variety of kiwifruit. Its flesh can range from reddish or pink tones to deeper red depending on the variety and ripeness.
Red Kiwi Nutrition Per 100 g
| Nutrient | Approximate amount per 100 g |
|---|---|
| Energy | 59 kcal |
| Protein | 0.9 g |
| Total fat | 0.4 g |
| Carbohydrates | 11.9 g |
| Total sugars | 11.4 g |
| Dietary fiber | 1.8 g |
| Vitamin C | 189 mg |
| Vitamin E | 1.6 mg |
| Folate | 69 µg |
| Potassium | 338 mg |
Note: Nutritional values can vary with variety, growing conditions, maturity, season, and analytical method. The published analysis of Zespri Red Kiwifruit reported 189 mg vitamin C, 1.8 g fibre and 338 mg potassium per 100 g.

WHICH FRUIT IS BETTER FOR FIBER?
Kiwi vs. Orange for Fiber
Both fruits provide dietary fiber.
Using the same 100-gram comparison, green kiwi provides approximately 3.0 grams of dietary fiber, while orange provides approximately 2.4 grams.
That makes kiwi slightly higher in fiber by weight.
Fiber is important for a balanced diet and can help support normal digestive health.
If increasing fiber intake is your goal, both fruits can fit into a varied diet.
WHICH HAS MORE POTASSIUM?
Kiwi vs. Orange for Potassium
Green kiwi also contains more potassium per 100 grams in the USDA comparison:
- Green kiwi: approximately 312 mg
- Orange: approximately 181 mg
Potassium is an essential mineral involved in normal nerve function, muscle contraction, and fluid balance.
Again, these numbers are a comparison by weight, not a claim that eating kiwi is automatically better for everyone.
WHICH HAS FEWER CALORIES?
Orange Has a Slight Advantage
If calories are your main concern, orange comes out lower in this comparison.
Per 100 grams:
- Orange: about 47 calories
- Green kiwi: about 61 calories
The difference is relatively small, and portion size matters.
For most people, the more useful question is whether the fruit fits into their overall eating pattern rather than choosing a fruit solely because it contains fewer calories.
CAN YOU EAT KIWI AND ORANGE TOGETHER?
Absolutely
There is no nutritional rule that says you have to choose one.
Kiwi and orange can work well together in:
- fruit salads
- breakfast bowls
- yogurt
- smoothies
- homemade fruit cups
- snack plates
Combining different fruits is also an easy way to add variety to your diet.
For example, you could combine sliced kiwi, orange segments, berries, and plain yogurt for a simple fruit-and-yogurt bowl.
DOES COOKING AFFECT VITAMIN C?
What About Fresh vs. Cooked Fruit?
Vitamin C is sensitive to heat and can be lost during cooking and food preparation.
For that reason, fresh fruits such as kiwi and oranges are convenient ways to include vitamin C without cooking them.
This doesn’t mean cooked foods are unhealthy. It simply means that preparation methods can affect the amount of some nutrients that remain in food.
For the comparison in this article, we’re talking about raw fruit.
CAN YOU GET TOO MUCH VITAMIN C?
Is More Always Better?
Not necessarily.
Vitamin C is important, but extremely high intakes, particularly from supplements, can cause problems.
The NIH lists the adult tolerable upper intake level at 2,000 mg per day from all sources, including food, beverages, and supplements. High supplemental intakes can cause symptoms such as diarrhea, nausea, and stomach cramps.
This doesn’t mean you should be worried about eating ordinary portions of kiwi or oranges.
For most people, getting vitamin C through a varied diet is preferable to trying to consume very large amounts through supplements.
SO, WHICH ONE SHOULD YOU CHOOSE?
Kiwi or Orange?
Here’s the simplest way to look at it:
Choose kiwi if:
- You want more vitamin C per 100 grams.
- You want slightly more fiber per 100 grams.
- You want a fruit with more potassium per 100 grams.
- You enjoy kiwi’s sweet-tart flavor.
Choose orange if:
- You enjoy citrus fruit.
- You want a lower-calorie option per 100 grams.
- You want a good source of vitamin C and folate.
- You prefer the taste and convenience of oranges.
Or choose both.
There is no need to turn nutrition into a competition.
Kiwi and oranges are both nutritious fruits, and eating a variety of fruits is generally more useful than relying on one “superfood.”
Frequently Asked Questions
FINAL VERDICT
Kiwi Wins the Vitamin C Comparison
If the question is specifically
Which has more vitamin C, kiwi or orange?
Green kiwi wins when the two fruits are compared by equal weight.
USDA data gives approximately:
92.7 mg vitamin C per 100 g of green kiwi
versus
53.2 mg vitamin C per 100 g of orange.
That’s a meaningful difference.
But orange is still an excellent fruit to include in a balanced diet. The best choice ultimately comes down to your overall diet, preferences, and nutritional needs.
Rather than choosing only one, you can simply enjoy both.
