What is it
Camu camu (Myrciaria dubia) is a small reddish-purple berry from a shrub native to the Amazon rainforest. It is one of the most concentrated natural sources of vitamin C known, with content far exceeding that of citrus fruits.

Evidence for 2 uses
AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.
immune support
Supplement benefitAdequate vitamin C supports normal immune function, and meta-analyses of vitamin C show small reductions in cold duration, particularly in deficient or highly stressed groups, rather than prevention in the general population. Camu camu delivers this benefit through its vitamin C content; evidence specific to camu camu beyond ascorbate is limited.
Bottom line: Supports immune function chiefly via its vitamin C, with modest, population-dependent effects on colds.
Evidence is mixed
Vitamin C trials show benefit on cold duration mostly in deficient or stressed people, not consistent prevention in healthy adults.
antioxidant and inflammatory markers
Biomarker supportSmall studies report that camu camu lowers oxidative-stress and inflammatory markers more than an equivalent dose of ascorbic acid, attributed to its anthocyanins and ellagic acid. These are biomarker changes in tiny trials and do not demonstrate any symptom or disease benefit.
Bottom line: May shift antioxidant and inflammation markers, but this is biomarker-level evidence only.

How to take it
What to track
2 commercial forms
Compare the main delivery options and what they’re best suited for.
Camu camu powder
Freeze-dried fruit powder, the most common form. Tart flavor often mixed into smoothies, juice, or yogurt. Vitamin C degrades with heat and air exposure.
Whole-fruit form; vitamin C content varies by processing and storage.
Standardized extract
Capsules with extract standardized to a specific vitamin C percentage. Reduces variability between batches.
Concentrated vitamin C content for precise dosing.
Safety
Know the common side effects, key cautions, and who should avoid it.
Common side effects
Serious risks
increased kidney-stone risk in susceptible people at high vitamin C intakes
Who should avoid it
- people with calcium-oxalate kidney stones
- those with iron-overload disorders
- people with G6PD deficiency at very high doses
Pregnancy & breastfeeding
Acceptable within the pregnancy vitamin C upper limit of about 1,800–2,000 mg/day; do not exceed it.
Interactions
high-dose vitamin C increases iron absorption
possible modest interaction at very high vitamin C doses

Frequently asked questions
How much vitamin C is in camu camu powder?⌄
Most camu camu powders contain 8 to 12 percent vitamin C, so a teaspoon (about 3 g) delivers around 250 to 400 mg. Check the label for the standardized amount.
Is camu camu better than synthetic vitamin C?⌄
The ascorbic acid molecule is identical. Camu camu provides additional polyphenols, which some research suggests may enhance antioxidant activity beyond vitamin C alone. For basic vitamin C needs, both work.
What does camu camu taste like?⌄
Very tart and sour, similar to extremely acidic citrus. It is rarely consumed plain; most people mix the powder into smoothies, juices, or other foods.
Will camu camu powder lose potency over time?⌄
Yes. Vitamin C degrades with exposure to heat, light, and air. Store the powder in a cool, dark place and use within a year of opening for best potency.
