Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Camu camu is an Amazonian berry exceptionally high in vitamin C, sold as an immune and antioxidant supplement. Its benefits largely reflect its vitamin C content.
What is Camu Camu?
Camu camu (Myrciaria dubia) is a small Amazonian fruit with one of the highest natural vitamin C contents of any food, sold as powder for immune and antioxidant support.
What Camu Camu is commonly used for
In supplements, Camu Camu is most often included for skin & anti-aging, respiratory & lung health support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.
How Camu Camu works
Its very high vitamin C and polyphenol content provide antioxidant and immune-supporting effects, which are the basis for its marketing.
What the evidence says
Here's an honest snapshot of what published research suggests about Camu Camu — including where the evidence is limited.
- Camu camu is a rich natural vitamin C source with some early antioxidant research, but specific human evidence beyond vitamin C's known roles is limited.
- Study quality and doses vary, and a result seen in research doesn't guarantee the same for any individual — use the sources below to check the current evidence on Camu Camu rather than relying on marketing claims.
Typical dosage used in studies
A small amount of powder can supply a large vitamin C dose; very high vitamin C intakes offer no extra benefit and can upset the stomach. This is general information from research, not a personal recommendation or a dosing instruction.
Side effects and safety
Camu camu is generally safe; its high vitamin C can cause digestive upset at large doses and may matter for people prone to kidney stones. As with any supplement, it's sensible to introduce Camu Camu on its own, use a trusted brand, and stop if you notice any reaction.
Medication interactions and who should avoid Camu Camu

If you take any regular medication, are pregnant or breastfeeding, or manage a health condition, confirm Camu Camu is appropriate for you before starting.
This is general information, not personal medical advice. If you take any medication, are pregnant or breastfeeding, or have a health condition, confirm it's safe to use Camu Camu with your doctor or pharmacist first.
