What fruit has 100% vitamin C?
What fruit has 100% vitamin C?
No fruit on Earth is 100% vitamin C — the richest one ever measured is roughly 3% vitamin C by weight, and almost everything else in it is water, fibre and sugar.
That sounds like bad news. It isn't. If what you meant was 100% of the Daily Value — the 90 mg figure printed on every nutrition label — then the answer flips completely. A single medium orange delivers 70 mg, and dozens of ordinary fruits clear the whole thing outright.
The interesting question is what happens after that.
Key Takeaways
- No fruit is anywhere near 100% vitamin C. The Kakadu plum, the richest ever recorded, measures 2,300 to 3,150 mg per 100 g of fresh fruit — between 2.3% and 3.1% by weight.
- The figure behind "100%" on a label is the Daily Value, and for vitamin C the FDA sets it at 90 mg for adults and children over four.
- One medium orange (70 mg) plus one kiwifruit (64 mg) comes to 134 mg, which clears the Daily Value by half again, using the NIH's own food figures.
- 100% of the Daily Value is a low bar by design. In the study that set the modern RDA, complete plasma saturation took 1,000 mg a day — more than eleven times the DV.
- Above 1 gram a day, less than half of what you swallow is absorbed. A 2025 scoping review of liposomal forms found 9 of 10 trials showed higher bioavailability, with AUC 1.3 to 7.2 times greater.

1. The literal answer: no fruit is 100% vitamin C
Nothing you can eat is 100% vitamin C. The only thing that qualifies is ascorbic acid powder in a jar, and that is a chemical, not a fruit. Every fruit is overwhelmingly water, with sugars, fibre and organic acids making up most of the remainder, and vitamin C appearing in milligrams rather than grams.
The ceiling is a long way below 100%. The Australian Kakadu plum holds the record, and a 2023 analysis in Molecules reports its fruit at 2,300 to 3,150 mg of ascorbic acid per 100 g of fresh weight, which the authors write out plainly as 2.3% to 3.1%. Dried down to a powder the concentration climbs, and the same paper cites a separate dry-weight measurement of about 14% — still nowhere near the number in the question.
For comparison, the same paper notes that acerola, long treated as the world's most vitamin-C-rich fruit, averages roughly 1.7% of fresh weight, and that acerola and camu camu together span 1,677 to 2,280 mg per 100 g. A fruit at 3% vitamin C is already an extraordinary outlier. There is no 100% fruit and there never was.
2. What you probably meant: 100% of the Daily Value
Almost everyone asking this question means the label figure. When a juice carton says "100% vitamin C", it is claiming one serving supplies a full Daily Value, and the FDA sets that Daily Value at 90 mg for adults and children aged four and over. Health Canada's Table of Daily Values sets the same 90 mg figure, so the label maths is identical on both sides of the border.
Against a 90 mg target, a surprising number of ordinary fruits and vegetables clear 100% on their own. Working from the food table on the NIH's vitamin C fact sheet:
- Half a cup of raw red sweet pepper: 95 mg, past the Daily Value by itself
- One medium orange: 70 mg, about 78% of the way there
- One medium kiwifruit: 64 mg, roughly 71%
- Half a cup of sliced strawberries: 49 mg, around 54%
Guava outstrips all of them — USDA FoodData Central puts common raw guava at 228 mg per 100 g, so a single small fruit is worth around 126 mg on its own — and it is the densest source you are likely to find in a supermarket. But the practical answer is that no single hero fruit is required: an orange and a kiwifruit eaten in the same day come to 134 mg, close to 150% of the Daily Value. If you want the fuller picture of which foods carry the most, our guide to the foods highest in vitamin C and where diet alone falls short covers vegetables as well as fruit. The notable exception is the fruit most people assume is a good source — a medium banana carries only about 10 mg on USDA's figures, as our look at whether bananas are rich in vitamin C sets out.
3. The actual record holders (and why you can't buy them)
Three fruits sit at the top of every vitamin C ranking, and none of them is sold fresh in a Western supermarket. The Kakadu plum (Terminalia ferdinandiana) is wild-harvested in northern Australia and reaches 2.3% to 3.1% vitamin C by fresh weight. Camu camu grows in the Amazon, and it and acerola are usually reported together at 1,677 to 2,280 mg per 100 g of fresh weight. Acerola, the Barbados cherry, averages about 1.7%.
What reaches consumers is powder, not fruit, and the numbers change accordingly. The 2023 Molecules study measured three batches of Kakadu plum powder at 15,839 to 18,125 mg per 100 g on a dry-weight basis — and found that batches from the same harvest varied by more than 2,000 mg between them. A powder's headline figure is a concentration, not a serving, and the same paper's blended products ranged from 959 to over 1,400 mg per 100 g depending on what else was in the mix.
There is a caution worth knowing. Kakadu plum carries oxalic acid alongside its ascorbic acid, which researchers writing in Food Research International flagged as a potential drawback of the fruit. The NIH separately notes that high vitamin C intakes can raise urinary oxalate. If you have a history of kidney stones, that is a conversation to have with your doctor before adding a concentrated botanical powder to your routine.
4. Why 100% of the Daily Value is a low bar
Here is the part the question accidentally exposes. The Daily Value was never set at the amount where vitamin C does the most; it was set near the amount that reliably prevents deficiency. The RDA is 90 mg for men and 75 mg for women, with smokers needing 35 mg a day more, and those figures anchor the label.
The research that produced the modern RDA reached considerably higher. In the depletion-repletion work published in the Proceedings of the National Academy of Sciences, circulating immune cells saturated at 100 mg daily while complete plasma saturation required 1,000 mg daily across seven volunteers given doses from 30 to 2,500 mg. That is more than eleven times the Daily Value for the upper figure — and it is why clinical bioavailability studies are run at 500 to 1,000 mg rather than at 90 mg.
Most people are already past the label figure without trying. NIH cites mean intakes from food alone of 105.2 mg a day for men and 83.6 mg for women. So if the goal is simply 100% of the Daily Value, the honest answer is that the average diet is roughly there already, and hunting for one perfect fruit solves a problem most readers do not have. The ceiling in the other direction is the tolerable upper intake level of 2,000 mg a day, which no realistic amount of fruit will approach.
5. Where the fruit bowl genuinely runs out
Two things limit what fruit can deliver, and neither is about picking a better fruit. The first is that vitamin C is fragile. NIH notes that content is reduced by prolonged storage and by cooking, because ascorbic acid is water-soluble and destroyed by heat — the reason a squeeze of lemon into a hot drink behaves differently than you might expect, as our piece on whether hot water destroys the vitamin C in lemon explains. The 70 mg on the chart is the number for a fresh orange, not one that has spent three weeks in transit.
The second limit is absorption, and it is the harder one. Your gut takes up 70% to 90% of vitamin C at intakes of 30 to 180 mg a day, which covers everything in the fruit list above. Above 1 gram a day, absorption falls to less than 50%, and the unmetabolised remainder leaves in your urine. That ceiling is the subject of our guide to what blocks vitamin C absorption, and it is why the delivery format starts to matter once you move past what food provides.
This is where liposomal delivery enters the picture. A 2025 scoping review of every published trial comparing liposomal with standard vitamin C found that 9 of 10 studies showed higher bioavailability, with peak concentrations 1.2 to 5.4 times higher and AUC 1.3 to 7.2 times higher. That absorption advantage is well established. Whether it changes clinical outcomes in people who are already replete has not been demonstrated, and we would rather say so than imply otherwise. Fruit still does things a capsule cannot, incidentally — around 50 mg of vitamin C in a meal is the point of optimum effect for improving iron absorption from that meal, though whole-diet studies find the effect largely washes out across a day's eating. It is an argument for the orange alongside the lentils rather than instead of them, and our guide to how the pairing works sets out both sides.
Bio Absorb Liposomal Vitamin C — what a supplement adds that fruit cannot
Fruit is not competing with a supplement, and any brand that tells you otherwise is selling rather than explaining. Produce brings fibre, potassium and polyphenols that no capsule contains, and for anyone comfortably clearing the 90 mg Daily Value from food, it may be all that is needed.
What a supplement offers is consistency and a route past the absorption ceiling described above. A fruit's vitamin C content shifts with variety, ripeness, storage and season — the 2023 Kakadu plum analysis found batches from a single harvest differing by more than 2,000 mg per 100 g. A manufactured product is measured rather than estimated.
Bio Absorb Nutraceuticals makes its liposomal vitamin C in two formats: Liposomal Vitamin C Liquid 1000mg (Corn-Free) and Liposomal Vitamin C Capsules 1000mg (Corn-Free), sharing an allergen profile that is non-GMO, gluten-free, nut-free, dairy-free and vegan. Both are third-party tested every batch and made in a GMP-certified Canadian facility. The liquid mixes into water or juice; the capsules need no refrigeration and travel well.
The corn-free part is less cosmetic than it sounds. Nearly all commercial ascorbic acid begins as corn starch, which is why our article on why the source of ascorbic acid matters exists at all. See current pricing and serving details for the liquid, or the full product specification for the capsules.
Frequently Asked Questions
Which fruit has the most vitamin C?
The Kakadu plum, at 2,300 to 3,150 mg per 100 g of fresh fruit, followed by camu camu and acerola. None is sold fresh outside its growing region, so in practice you will meet them as powders. Among fruits you can actually buy, guava is the densest, with oranges, kiwifruit and strawberries close behind.
Does one orange give you 100% of your daily vitamin C?
Not quite, but close. A medium orange supplies about 70 mg against a 90 mg Daily Value, or roughly 78%. Add a kiwifruit at 64 mg and you are at 134 mg, comfortably past 100%.
Is it better to get vitamin C from fruit or from a supplement?
For reaching the 90 mg Daily Value, fruit does the job and brings fibre and other nutrients with it. Supplements become relevant above that level, where absorption drops below 50% past 1 gram a day and delivery format starts to matter. It is not an either-or.
Can you get too much vitamin C from fruit?
Realistically, no. The tolerable upper intake level for adults is 2,000 mg a day, and reaching that from whole fruit would mean eating several kilograms of it. Concentrated botanical powders are a different matter, particularly ones carrying oxalic acid, and anyone with kidney disease, haemochromatosis or a regular medication should check with a doctor first.
Do camu camu and acerola powders count as fruit?
They are fruit-derived, but the label figure is for a dried concentrate, not the fresh fruit. Batch variation is substantial — the same 2023 study found three powder batches from one harvest spanning 15,839 to 18,125 mg per 100 g. Treat a powder's number as an estimate of that batch, not a property of the species.
Why do so many sources give different vitamin C figures for the same fruit?
Because variety, ripeness, growing conditions, storage time and cooking all move the number, and vitamin C is destroyed by heat and reduced by prolonged storage. A range of 2,300 to 3,150 mg for one species is not sloppy measurement — it is the fruit genuinely varying that much.
Conclusion
No fruit is 100% vitamin C, and the closest thing to it tops out near 3% by weight — but if you meant 100% of the 90 mg Daily Value, an orange and a kiwifruit settle the question before lunch. The more useful thing to know is that the Daily Value is a deficiency threshold, not an optimum, and that absorption falls below 50% above 1 gram a day.
