If you have spent any time reading vitamin C marketing, you have seen the claim: camu camu is the richest source of vitamin C on the planet, and it is not exaggerated. We are not going to pretend otherwise. What we want to do here is give you the honest comparison, the number, the form each fruit actually reaches you in, and let you decide what matters more to you.
The short version: camu camu carries far more vitamin C per 100 g than sea buckthorn, and no honest source disputes that. The real question is not the biggest number on a label. It is what form the fruit takes by the time it reaches you, whole and intact, or processed down to a powder.
The number, stated plainly
According to PubMed, a Brazilian food composition dataset compiled from the country's official food table identified camu camu (Myrciaria dubia) as the richest measured source of vitamin C among the foods studied, at roughly 2,300 mg of ascorbic acid per 100 g edible portion, about 48 times the vitamin C content of an orange (Grande et al., 2020, Maternal and Child Nutrition, DOI: 10.1111/mcn.13005). That is an extraordinary number and it is a real one. Sea buckthorn is also vitamin C dense by fruit standards, but it does not approach camu camu gram for gram. If your only question is "which fruit has more vitamin C per 100 g," camu camu wins, plainly and by a wide margin.
So why does Human Renaissance make sea buckthorn, not camu camu? Because the number on a nutrition label and the food that actually reaches your body are two different questions.
What form does each fruit actually reach you in?
Camu camu is a small, extremely sour Amazonian fruit that spoils within days of harvest. It is almost never sold whole, not because whole camu camu is undesirable, but because it cannot survive shipping. What reaches Western shelves is camu camu powder, made by drying and grinding the fruit, sometimes freeze-dried, sometimes spray-dried at heat. According to PubMed, researchers studying camu camu powders found that the drying method and encapsulating agent used changed how well ascorbic acid and other bioactive compounds survived processing, and that storage humidity was a critical variable in whether those compounds held up over time (García-Chacón et al., 2023, Food Research International, DOI: 10.1016/j.foodres.2023.113820). In other words, the vitamin C content printed on a camu camu powder label is a snapshot of the raw fruit, not a guarantee of what survives drying, storage and time on a shelf.
Sea buckthorn has a similar fragility problem, and we do not pretend otherwise. Its pulp carries fragile oils and a native vitamin C and polyphenol matrix that also degrade under heat. A study on drying methods for sea buckthorn berries found that ascorbic acid content dropped by 45 percent under vacuum freeze-drying, the gentlest method tested, and by as much as 80 percent under ordinary hot-air drying (Geng et al., 2023, Frontiers in Nutrition, DOI: 10.3389/fnut.2023.1106009). That is exactly why we do not dry our berries. We press the whole fruit, seal it in single-serve pouches, and never expose it to the heat and open air that a drying process requires.
This is worth sitting with for a moment, because it applies to both fruits the same way. Any fruit that gets dried loses something. The question is never whether processing changes a fruit, it always does, the question is how much of the original food is still there when it reaches your mouth. A camu camu powder label reflects a laboratory measurement of the raw pulp before drying, not a guarantee printed on the finished jar after months on a shelf. A sea buckthorn label that quoted the fresh, undried berry would carry the same honesty problem. We chose to quote and sell the pressed, sealed, undried form specifically so that the number on our label is the number in the pouch, not a number measured before processing took its cut.
Where does sea buckthorn sit?
Human Renaissance is the only sea buckthorn puree in the world sold in a single-serve pouch. 190+ naturally occurring compounds, omega 3, 6, 7 and 9, 201 mg of vitamin C per pouch, 0 g sugar, 5,640 hand-picked berries per box.
That 201 mg is not the biggest vitamin C number you will find in a health food aisle. Camu camu powder can legitimately claim more per gram. But 201 mg is real, whole-fruit vitamin C, sitting inside its native matrix of carotenoids, flavonoids and the omega-3, 6, 7 and 9 fats that a dried powder does not carry at all, because a powder is fruit with the water and the fat pressed or dried out of it.
Whole fruit versus isolated powder
This is the actual comparison worth making. Camu camu, as sold, is a processed extract: harvested, dried or freeze-dried, ground, packaged, and reconstituted into your smoothie or water as a fine powder. It is a legitimate and concentrated vitamin C source, and nothing here disputes that. But it is not the whole fruit anymore. The oils are gone. The moisture is gone. What is left is what survived the drying process.
Sea buckthorn puree, pressed and sealed without drying, keeps the fruit whole. You are getting the vitamin C alongside the omega fats, the carotenoids, and the rest of the roughly 190 compounds naturally occurring in the berry, in the ratios the fruit actually grows them in. Neither approach is a medicine and neither fruit treats or cures anything. The difference is simply this: one is a concentrated isolate, the other is an intact whole food.
There is nothing wrong with an isolate. Vitamin C isolates and food powders have a real place, they are shelf-stable, easy to dose, and inexpensive to ship compared to a perishable whole fruit. Camu camu earned its reputation honestly: it really is that vitamin C dense, and a spoonful of the powder really does deliver a large single-nutrient hit. What an isolate cannot do is hand you back the fat-soluble compounds that traveled with the vitamin C inside the living fruit. Carotenoids, tocopherols and the omega fatty acid family are not water-soluble, they do not survive an aqueous extraction or a drying process the way a robust molecule like ascorbic acid can, so a powder built around vitamin C is, by its nature, built around one part of the fruit rather than the whole of it.
The comparison in one table
| Measure | Camu camu (as sold) | Sea buckthorn (Human Renaissance) |
|---|---|---|
| Vitamin C, raw fruit basis | ~2,300 mg per 100 g, the richest measured of any fruit | High for a fruit, well below camu camu gram for gram |
| Form sold | Dried or freeze-dried powder, ground and encapsulated | Whole berry, pressed and sealed, never dried |
| Vitamin C per serving, as consumed | Varies by drying method and storage; not label-fixed | 201 mg per 30 mL pouch, label-verified |
| Fat profile | Negligible; oils are removed in processing | Omega 3, 6, 7 and 9 intact in the whole fruit |
| Sugar | Depends on brand and dilution | 0 g per pouch |
| Compound matrix | Concentrated on ascorbic acid and a few phenolics that survive drying | 190+ naturally occurring compounds intact together |
Which one should you actually choose?
If your goal is the single highest vitamin C number per gram on a supplement shelf, camu camu powder is the honest answer, and we are not going to tell you otherwise to make a sale. If your goal is a daily whole food that carries vitamin C inside its complete natural matrix, alongside a fat profile that includes omega-7, a fatty acid found in very few foods at all, sea buckthorn puree is the more complete food. They are not really competing for the same job. One is a concentrated additive. The other is a fruit you drink.
Frequently asked
Is camu camu's vitamin C claim real?
Yes. It is one of the most vitamin C dense fruits ever measured, and the number is well documented in the published food composition literature. We are not disputing it.
Does drying destroy all the vitamin C in camu camu powder?
No, but it changes it. Published research on camu camu powder processing shows that ascorbic acid retention depends heavily on the drying method, the encapsulating agent, and storage humidity, meaning the number on a jar reflects the raw fruit, not necessarily what is left by the time you consume it.
Why doesn't Human Renaissance just dry sea buckthorn the same way and quote a bigger number?
Because drying sea buckthorn measurably destroys much of its native vitamin C and its oils, the two things that make the berry worth drinking in the first place. Published drying studies on sea buckthorn show ascorbic acid losses ranging from roughly 45 to 80 percent depending on the method. We press and seal instead, specifically to avoid that loss.
Can you take both?
Of course. They are foods, not competing medicines. Camu camu powder in a smoothie and a whole-fruit sea buckthorn pouch answer different questions and there is no conflict in using both.
You do not have to chase the biggest vitamin C number on a label. You can turn the pouch over, read what is actually in it, one whole berry, and decide for yourself.
This is education about food science, not medical advice, and nothing here treats, cures or prevents any condition.
