Mango is a genuinely good source of vitamin C. One cup (165 grams) of fresh mango delivers about 67% of the daily value, making it one of the more vitamin C-rich fruits you can eat. For most adults, that single cup covers well over half of what you need for the entire day.
How Much Vitamin C Is in a Mango
The recommended daily intake of vitamin C is 90 mg for adult men and 75 mg for adult women. Smokers need an extra 35 mg on top of that. A cup of fresh mango gets you roughly two-thirds of the way there in one sitting, which puts it ahead of many fruits people assume are better sources.
To put this in perspective, a cup of mango delivers more vitamin C than a cup of blueberries or a cup of pineapple. It’s not quite at the level of an orange or a cup of strawberries, but it’s in the same general tier. If you eat a cup of mango alongside other fruits and vegetables throughout the day, you’ll easily hit 100% of your needs without thinking about it.
Variety Matters More Than You’d Expect
Not all mangoes are created equal when it comes to vitamin C. Research from the University of Puerto Rico measured vitamin C across dozens of mango cultivars and found enormous variation. The Julie variety topped the list at nearly 63 mg per 100 grams of pulp, while the Keitt variety (a common supermarket mango in the U.S.) contained just 3.4 mg per 100 grams. That’s roughly an 18-fold difference between two fruits sitting in the same produce section.
Some other varieties with strong vitamin C levels include Francisque (52 mg), Carrie (46 mg), Edward (38 mg), and Irwin (37 mg). Kent, another variety you’ll see in grocery stores, lands in the middle at about 26 mg per 100 grams. The popular Haden came in at just 15 mg. If you’re eating mango specifically for vitamin C, smaller, more aromatic varieties tend to outperform the large commercial ones, though this isn’t a hard rule.
Ripeness Changes the Vitamin C Content
A mango that ripens naturally on the tree contains more vitamin C than one picked green and ripened off the tree or with artificial methods. Research comparing natural and artificial ripening found that naturally ripened mangoes had about 7.6 mg more vitamin C per 100 grams on average. The reason is straightforward: the longer a mango stays on the tree, the more time its starches have to convert into ascorbic acid (vitamin C) through normal metabolic pathways.
Most mangoes sold in North America and Europe are picked unripe and shipped long distances, so they likely contain somewhat less vitamin C than tree-ripened fruit. This doesn’t make them a poor source, but it’s worth knowing that a mango from a local tree in a warm climate will generally pack more nutritional punch than an imported one.
Fresh vs. Frozen Mango
Vitamin C in fresh produce starts declining the moment it’s harvested and keeps dropping during transport and storage. If a fresh mango sits on the counter or in your fridge for several days, it may lose a meaningful portion of its vitamin C before you eat it.
Frozen mango is blanched briefly in hot water before freezing, which does cause some initial vitamin C loss. That loss can range from 10% to 80% depending on the process, with the average hovering around 50%. However, once frozen, nutrient levels stay relatively stable. So if you’re choosing between a frozen mango eaten within a few months and a fresh mango that’s been sitting in your kitchen for a week, the frozen version may actually retain comparable or even higher vitamin C levels. For practical purposes, both fresh and frozen mango are reasonable choices.
What Mango’s Vitamin C Does for You
Vitamin C plays a well-known role in immune function and skin health, but one of its most practical benefits is improving iron absorption. Your body has a harder time absorbing iron from plant-based foods like beans, lentils, and spinach compared to iron from meat. Eating vitamin C alongside these foods significantly boosts absorption. Pairing mango with a grain bowl, a bean salad, or iron-fortified cereal is a simple way to get more from the iron already in your diet. This is especially relevant for vegetarians, vegans, and anyone prone to low iron levels.
Mango also contains polyphenols, particularly a compound called mangiferin, along with gallic acid. These work together with vitamin C to provide antioxidant protection. Research published in the Journal of Agricultural and Food Chemistry found that the combined effect of vitamin C and these polyphenols in mango is greater than what you’d expect from each compound alone. Both vitamin C and mangiferin share a chemical feature that makes them effective at neutralizing free radicals, and they also help chelate metals that would otherwise promote oxidative damage. In short, mango’s vitamin C doesn’t work in isolation. It’s part of a package that makes the whole fruit more beneficial than a supplement delivering the same amount of vitamin C.
How Mango Compares to Other Fruits
- Orange (1 cup, sectioned): about 95 mg of vitamin C, roughly 106% of the daily value
- Mango (1 cup, sliced): about 60 mg of vitamin C, roughly 67% of the daily value
- Pineapple (1 cup, chunks): about 79 mg of vitamin C, roughly 88% of the daily value
- Banana (1 medium): about 10 mg of vitamin C, roughly 11% of the daily value
- Strawberries (1 cup, halves): about 89 mg of vitamin C, roughly 99% of the daily value
Mango holds its own against most popular fruits. It’s not the single highest source, but it’s well above average, and unlike citrus, it brings a meaningful amount of vitamin A (as beta-carotene) along with it. If you enjoy mango, there’s no reason to swap it out for something else just to chase more vitamin C.
