A single medium green kiwi contains about 64 mg of vitamin C, which covers roughly 70% of the daily recommended intake for most adults. That already makes it one of the most vitamin C-dense fruits you can buy, but the variety you choose matters a lot. Gold kiwis pack nearly twice as much.
Vitamin C by Kiwi Variety
The standard green kiwi most people know (the Hayward variety) contains about 85 mg of vitamin C per 100 grams of flesh. Since a medium green kiwi weighs around 70 to 75 grams without the skin, you’re getting roughly 60 to 65 mg per fruit.
Gold kiwis are a different story. The SunGold variety contains 161 mg per 100 grams of edible flesh, nearly double the standard green. A newer “Sweet Green” variety lands in between at 150 mg per 100 grams. If you’re specifically trying to maximize your vitamin C intake, gold kiwis are one of the most efficient whole foods available. Eating just one medium gold kiwi delivers well over 100% of the daily value.
The daily recommended intake for vitamin C is 90 mg for adult men and 75 mg for adult women. So even a single standard green kiwi gets you most of the way there, and a gold kiwi overshoots it comfortably.
How Kiwi Compares to Oranges
Oranges are the fruit most people associate with vitamin C, but kiwis beat them gram for gram. An orange contains about 59 mg of vitamin C per 100 grams. A green kiwi has 85 to 93 mg per 100 grams, and a gold kiwi nearly triples the orange at 161 mg per 100 grams.
A whole medium orange does contain about 70 mg of vitamin C total, which is slightly more than a medium green kiwi in absolute terms. That’s simply because oranges are larger. By weight, the kiwi is the more concentrated source. If you ate the same weight of kiwi as you would an orange, you’d get significantly more vitamin C from the kiwi.
Eating the Skin Adds More
Kiwi skin is edible, and eating it increases your vitamin C intake beyond what the flesh alone provides. The fuzzy brown skin of green kiwis can be off-putting, but gold kiwis have smoother, thinner skin that’s easier to eat. Washing the fruit and biting in like an apple is the simplest approach. Beyond vitamin C, the skin adds extra fiber to each serving.
Kiwi vs. Vitamin C Supplements
A randomized study comparing vitamin C from gold kiwifruit to a synthetic vitamin C tablet of the same dose (50 mg) found no difference in bioavailability. Participants who ate half a gold kiwi per day for six weeks saw the same increases in blood, cell, and tissue vitamin C levels as those who took the supplement. The other nutrients and plant compounds in kiwifruit didn’t enhance or inhibit vitamin C absorption.
This means you’re not getting a “bonus” absorption effect from eating whole fruit compared to popping a tablet, at least for vitamin C specifically. But kiwis come with fiber, potassium, vitamin K, and other compounds that a supplement doesn’t provide, so you’re still getting more nutritional value overall from the fruit.
Getting the Most Vitamin C From Kiwi
Vitamin C breaks down with heat, so eating kiwis raw preserves the full amount. Storing them at room temperature is fine for a few days, but refrigeration slows vitamin C degradation over time. A ripe kiwi stored in the fridge will retain more of its vitamin C than one left on the counter for a week.
If your goal is to hit or exceed the daily value from a single piece of fruit, a gold kiwi is one of the best options available. Two green kiwis will also get you well past 100% of the daily value, with fewer than 100 calories combined. For context, you’d need to eat about two medium oranges or roughly eight strawberries to match what one gold kiwi delivers.
