Kakadu plum nutrition is led by vitamin C. Our lab-tested powder has 121mg in every gram, which gram for gram is 240 times the vitamin C of a fresh orange.
Kakadu plum (Terminalia ferdinandiana) also carries vitamin E, folate, lutein, antioxidants at 10.5 times a blueberry and 11 named tannins. Its seed is 32% protein and rich in minerals. Australian Government lab scans found over 100 compounds in the fruit (Konczak et al., 2009).
This page takes them one at a time, with the numbers, and links to the full guide for each.

Vitamin C: the headline nutrient
The Australian Government’s 2009 study found Kakadu plum had the highest vitamin C of every fruit, herb and spice it tested, recording 7,253mg per 100g of dried fruit in its own samples (Konczak et al., 2009). Our own powder is independently lab tested at 12.1% natural vitamin C, 121mg in every gram, so one 500mg capsule gives you 60mg, more than an adult’s 45mg daily need. The Government figure and ours come from different samples, and vitamin C varies naturally between trees and seasons, which is why we test our own.
Vitamin C contributes to normal immune system function, to iron absorption from food, to the reduction of tiredness and fatigue, to normal collagen formation for the normal function of skin, and to cell protection from free radical damage. The full vitamin C science →
Antioxidants and tannins
The same Government testing put Kakadu plum’s total antioxidant power at 10.5 times a blueberry on the FRAP test and 5.7 times on the ORAC test, with 4.7 times the total antioxidant compounds (Konczak et al., 2009). Most of that comes from tannins, the plant polyphenols behind the dry feel of strong tea. Researchers have named 11 in Kakadu plum, more than in any other fruit in the published research, pomegranate included, and one of them, terminalagin, appears to be unique to it. Antioxidants → · Tannins →
Vitamin E
Kakadu plum carries 6.1mg of vitamin E per 100g dried, the highest of the fruits tested in the Government study, which described it as comparable to a Hass avocado (Konczak et al., 2009). 98% of it is alpha-tocopherol, the form your body uses most readily. Vitamin E contributes to cell protection from free radical damage. Vitamin E foods, ranked →
Minerals: fruit vs seed
Most of Kakadu plum’s minerals sit in the seed kernel, which most processors throw away. We keep it. Per 100g dried:
| Mineral | Fruit | Seed |
|---|---|---|
| Calcium | 282mg | 539mg |
| Magnesium | 204mg | 421mg |
| Phosphorus | 52mg | 873mg |
| Potassium | 1,906mg | 669mg |
| Iron | 4.0mg | 6.1mg |
| Zinc | 0.57mg | 6.0mg |
| Copper | 0.30mg | 2.5mg |
| Manganese | 3.5mg | 9.1mg |
Fruit: Australian Government (RIRDC) 2009 study. Seed: Akter et al., Foods, 2018.
The published data proves it: the seed holds more than the fruit in 7 of these 8 minerals, up to 17 times more phosphorus, 10 times more zinc and 8 times more copper, while the fruit holds more potassium. That is why we keep the seed: the whole fruit, seed and all, gives you more than either part alone. What’s inside the seed → · Magnesium-rich foods →
Protein in the seed
A 2018 study measured the dried Kakadu plum seed kernel at 32% protein, just below soybeans (36%) and above pumpkin seeds (30%), lentils and chickpeas, and the researchers concluded it could be a new protein source. It’s also 35% fat, about four-fifths unsaturated. Our capsules are taken for their vitamin C, so the seed’s protein comes as a bonus rather than a protein serve. Plant based protein sources, ranked →
How the nutrients work together: collagen
Your body can’t make stable collagen without vitamin C: the two enzymes that build it need vitamin C and iron to work, copper then locks the fibres together, and manganese recycles the raw material. Kakadu plum has all four, and the seed carries the most minerals. Vitamin C contributes to normal collagen formation for the normal function of skin. What does collagen do? →

What are the health benefits of Kakadu plum?
Kakadu plum’s standout nutrient is vitamin C, and vitamin C contributes to normal immune system function, iron absorption from food, the reduction of tiredness and fatigue, normal collagen formation for the normal function of skin, and cell protection from free radical damage.

Are Kakadu plums the world’s healthiest fruit?
No single fruit can claim that, because “healthiest” depends on what you measure. Kakadu plum (Terminalia ferdinandiana) leads on several measurable nutrients. The Australian Government’s 2009 study found the highest vitamin C of any fruit, herb or spice it tested (7,253mg per 100g dried), the highest vitamin E of the fruits tested (6.1mg per 100g), and antioxidant power 10.5 times a blueberry on the FRAP test. Our lab-tested powder has 121mg of vitamin C per gram, which is 240 times the vitamin C of a fresh orange, gram for gram. Eat it as part of a varied diet with plenty of other fruit and vegetables.
What is the healthiest fruit on Earth?
There isn’t one answer, because “healthiest” depends on the nutrient. For vitamin C, Kakadu plum is the standout: gram for gram, our lab-tested powder has 240 times the vitamin C of a fresh orange. A varied mix of fruit and vegetables is healthier than any single fruit.
Can you eat Kakadu plums raw?
Yes. Aboriginal people have eaten Kakadu plums raw for tens of thousands of years. The fresh fruit is very tart and has a short season in the north, so most people eat it as freeze-dried powder or in capsules.
Does Kakadu Plum lighten skin?
Kakadu plum is popular in skincare because of its vitamin C, which is used for a brighter-looking complexion. Eaten, vitamin C contributes to normal collagen formation for the normal function of skin. There’s no strong evidence that eating it lightens skin colour.
How much vitamin C is in Kakadu plum?
The Australian Government recorded 7,253mg per 100g of dried Kakadu plum. Our own powder is lab tested at 12.1% natural vitamin C, 121mg per gram, which is 60mg in each 500mg capsule.
Is the seed of Kakadu plum edible?
Yes, when it’s processed. The dried seed kernel is 32% protein and rich in minerals, and the 2018 study found heavy metals well within food safety limits. We mill it fine with the fruit, so there’s no grit.
