In the Amazon rainforest, an unassuming tree with small red-purple berries grows on riverbanks. Nothing special on the outside — until you measure its vitamin C content: 2,000 to 3,000 mg per 100 grams, 30 to 60 times more than an orange. This makes Camu Camu (Myrciaria dubia) the highest natural source of vitamin C in the world, plus it's rich in anthocyanins, polyphenols, and bioflavonoids. At Plenthera, you'll find premium camu camu as wholefood powder and capsules — freeze-dried to preserve the delicate vitamin C.
Which camu camu is right for you?
| Form | Vitamin C | Best for |
|---|---|---|
| Powder standardized 10% | ~100 mg per gram | Wholefood, smoothies, daily |
| Powder standardized 20% | ~200 mg per gram | Higher dose wholefood |
| Capsules | 50-200 mg per capsule | On the go, convenience |
| Whole fruit powder | Variable | Maximum wholefood, no extract |
| Camu + Acerola mix | Combined | Broad antioxidant profile |
What is camu camu?
Camu Camu (Myrciaria dubia) is a small, round, red-purple berry native to the Amazon rainforest, especially from Peru and Brazil. The fruit has the highest natural vitamin C concentration in the world — 2,000-3,000 mg per 100 grams of fresh fruit — plus anthocyanins, polyphenols, and bioflavonoids in a wholefood matrix.
The camu camu tree grows on riverbanks in the Amazon lowlands. It's a true "flood tree" — during the wet season, it often stands underwater for weeks, and its berries are eaten by fish and thus spread. Local Peruvian and Brazilian communities have harvested the fruit for centuries, initially only for their own consumption. The commercial world only discovered camu camu in the 1990s, when analytical laboratory research revealed its exceptionally high vitamin C content.
What distinguishes camu camu from other natural vitamin C sources is not only the quantity but also the matrix. Its red-purple color comes from anthocyanins — the same pigment class as in blueberries, aronia, and blackcurrant. In addition, the fruit contains polyphenols, vitamin C bioflavonoids such as quercetin and rutin, and small amounts of carotenoids, potassium, and B vitamins. For those who prefer a wholefood approach over synthetic ascorbic acid, camu camu is one of the most attractive options.
One point of attention: vitamin C in camu camu is sensitive to heat. At high temperatures during drying or processing, a significant portion can be lost. Premium camu camu powder is therefore freeze-dried (lyophilization) or dried at low temperatures, so that the original vitamin C status is preserved. Also check out our acerola category for the Caribbean counterpart and our vitamin C category for the broader context with synthetic and buffered forms.
Vitamin C claims via camu camu
For camu camu itself, there are no health claims recognized by EFSA. However, because the fruit is rich in vitamin C, the recognized vitamin C claims (immune, collagen, energy, iron absorption, etc.) apply when the specific camu camu product provides the threshold of 12 mg of vitamin C per serving. With 10% standardized extracts, this is easily achieved with 1 gram of powder.
For the other components — anthocyanins, polyphenols, bioflavonoids — there are no specific recognized EFSA claims, although research does indicate antioxidant properties. Therefore, we do not make literal efficacy claims specifically about camu camu, but refer to the recognized vitamin C claims via the vitamin C present.
Camu camu is a dietary supplement, not a medicine.
Camu Camu vs Acerola — two American vitamin C titans
Both are natural vitamin C superfruits with similar concentrations, but with their own identity:
Camu Camu (Myrciaria dubia, Amazon): Highest natural vitamin C in the world (2,000-3,000 mg/100g fresh). High anthocyanin content — purple-red color. Slightly sour-bitter taste. Wild harvest from Peru/Brazil, sustainability a point of attention.
Acerola (Malpighia emarginata, Caribbean): Comparably high vitamin C (1,500-4,500 mg/100g fresh). Color more red than purple. Milder taste, often used in children's supplements. Broad plantation production in Brazil.
Which one do you choose?: For specific anthocyanin bonus: camu camu. For milder taste (children): acerola. For absolute wholefood vitamin C: both are equivalent. Some users choose both or a mixed formula.
Synergy: Camu camu and acerola can be used together perfectly — both provide wholefood vitamin C with different plant matrices.

How to use camu camu?
Simple basic approach for camu camu:
- Determine your goal: daily wholefood vitamin C (1-2 grams of powder), broad support (2-3 grams), or capsule route (1-2 capsules).
- Mix the powder with cold or lukewarm water — not with hot drinks (vitamin C oxidizes).
- Combine with smoothies, juices, or yogurt for flavor masking — camu camu is slightly sour to bitter.
- Intake can be at any time; for a sensitive stomach, preferably with a meal.
- For maximum wholefood effect: combine with other antioxidant sources (acerola, cacao, spirulina).
- Store the powder in a cool, dry place, in dark packaging — vitamin C oxidizes with light and heat.
- Preferably choose sustainably harvested or fair-trade certified brands — Amazon harvest is an ecological concern.
Myths and misconceptions about camu camu
Myth 1: "Camu camu works much better than other vitamin C sources."
At the vitamin C level: ascorbic acid is molecularly identical whether it comes from camu camu, acerola, or synthetically. What distinguishes camu camu is the matrix with anthocyanins and polyphenols — interesting for a wholefood approach, not necessarily superior in absolute efficacy.
Myth 2: "The more camu camu, the more immune effect."
Above 1,000 mg of vitamin C/day, stomach complaints are more common without additional immune effect demonstrated. The saturation point for most people is around 200-400 mg/day. For broad support, targeted dosing is more effective than mega-dosing.
Myth 3: "Wild camu camu is always the best choice."
Not automatically. Wild harvesting from the Amazon rainforest has ecological consequences if not managed sustainably. Some premium brands work with cultivated camu camu in agroforestry systems — less pressure on the wild ecosystem, comparable quality.
Myth 4: "Camu camu can completely replace synthetic ascorbic acid."
For pure vitamin C intake: yes. For cost-efficiency: synthetic is much cheaper. The choice is a philosophical one — wholefood approach (camu) or purity approach (synthetic ascorbic acid).
Combining Camu Camu with other supplements
Camu camu is often combined for antioxidant or immune themes. Commonly chosen combinations:
- Acerola: complementary wholefood vitamin C.
- Synthetic Vitamin C: for those who want certainty about absolute dosage.
- Spirulina: superfood stack with a broad micronutrient profile.
- Chlorella: complementary algae supplement.
- Iron: vitamin C increases non-heme iron absorption.
- Collagen: vitamin C as a cofactor in collagen synthesis.
- Zinc: classic immune combination.
Frequently asked questions

Amazonian fruit (Myrciaria dubia) with the highest natural vitamin C in the world (2,000-3,000 mg per 100g fresh). Plus anthocyanins, polyphenols, and bioflavonoids.
What is the difference between camu camu and acerola?
Both have similar vitamin C content. Camu camu: Amazonian, high anthocyanins, purple-red. Acerola: Caribbean, milder taste profile.
How much camu camu per day?
500-3,000 mg powder depending on standardization. 10% extract: 1 g = 100 mg vitamin C.
When to take camu camu?
Timing is flexible. Not with hot drinks — vitamin C oxidizes.
Which camu camu is best?
Freeze-dried, standardized for vitamin C content, sustainably harvested (fair-trade or agroforestry).
Does camu camu help the immune system?
Via vitamin C — EFSA-recognized claim for the immune system. No specific camu claim.
Camu camu vs synthetic ascorbic acid?
Molecularly identical in terms of vitamin C. Camu camu also provides anthocyanins and polyphenols. Synthetic is cheaper and equally effective in terms of pure vitamin C.
Does camu camu have side effects?
Generally well tolerated. At high doses (>1,000 mg vitamin C), stomach complaints are possible.
Is camu camu sustainable?
A point of attention. Choose brands with fair-trade or agroforestry — no unchecked wild harvesting from the Amazon.
What are anthocyanins in camu camu?
Purple-red pigments — antioxidants in the same class as in blueberries and aronia.
