Camu Camu (Myrciaria dubia) is an Amazonian berry known for very high vitamin C content and a range of polyphenol antioxidants. It is commonly used as a powder or supplement.

What are the main benefits of Camu Camu?

It is primarily used to support vitamin C intake, antioxidant defenses, and immune function. Some evidence also suggests it may help with inflammation and metabolic markers, but results are not definitive.

How much Camu Camu powder should I take?

Common supplemental amounts are about 1–5 g per day, depending on product concentration and vitamin C content. Start low and follow the label, especially if combining with other vitamin C sources.

Are there side effects or precautions with Camu Camu?

Because it is rich in vitamin C, high intakes may cause gastrointestinal upset in some people. Use caution if you have conditions affected by high vitamin C intake or if you take medications and consult a clinician if unsure.

Safety & Information

Important safety information & known risks

For educational purposes only • not medical advice

Generally recognized as safe in typical supplement doses, with primary concerns for iron overload, kidney stones, and possible drug interactions at high intakes.

warning notices

High vitamin C intake can cause digestive discomfort, including diarrhea or cramping in sensitive people.
Use with caution if you have a history of kidney stones or iron overload.
Monitor total vitamin C intake from all sources.
Avoid use if you have hemochromatosis or iron overload disorders due to enhanced iron absorption.
Use only with clinician supervision if taking anticoagulant or antiplatelet medications, as high vitamin C may affect bleeding risk.
Avoid excessive doses (above 2000 mg vitamin C/day) to minimize risk of kidney stones or digestive upset in sensitive individuals.

Known interactions with medications

Possible interaction with anticoagulant and antiplatelet medications at high doses.

Contraindications / special precautions

Hemochromatosis (iron overload disorders)
History of kidney stones (especially oxalate stones)

interactions

Important interactions between active ingredient ↔ supplement / medication / food

Major considerations relate to high vitamin C content and its influence on nutrient and drug absorption.

Camu Camu increases non-heme iron absorption due to high vitamin C.

nutrient · Iron

PairModerateTake together

Why

Vitamin C enhances conversion of non-heme iron to its more absorbable form.

recommendation

Those with iron overload disorders should avoid Camu Camu; those needing more iron may benefit from co-administration.

1 · Healthline 5 · NIH Office of Dietary Supplements: Vitamin C

High vitamin C may interact with anticoagulant and antiplatelet drugs.

drug · Anticoagulants (e.g., warfarin)

CautionLimited

Why

High doses of vitamin C may influence platelet aggregation or affect drug efficacy.

recommendation

Monitor for altered bleeding risk and consult your clinician for high vitamin C intake (>1000 mg/day).

4 · RxList

High vitamin C may increase risk of kidney stones in predisposed individuals.

lifestyle · History of kidney stones

AvoidModerate

Why

Vitamin C metabolizes to oxalate, potentially increasing stone formation, especially in males.

recommendation

Avoid large doses of Camu Camu or supplemental vitamin C if you have a history of kidney stones.
