Camu Camu

Supplements · Antioxidants · Supplement, Typed Supps

A small, tart Amazon rainforest berry that packs an extraordinary amount of natural vitamin C — one of the richest known food sources of it.

Stage by stage

Intake (Powder, juice, or capsule): Consumed due to the raw fruit's intense tartness.
Small intestine (Absorbed): Vitamin C and polyphenols absorbed alongside normal digestion.
Bloodstream (Circulates): Carried through the blood to tissues throughout the body.
Tissue effects (Immune cells, collagen, antioxidant systems): Vitamin C supports immune function and collagen synthesis and acts as an antioxidant throughout the body.

What the evidence supports

Delivering a highly concentrated, bioavailable dose of vitamin C — strong evidence. Camu camu pulp reliably measures among the highest vitamin C concentrations of any fruit tested, and this is well documented analytically — it’s simply a very potent whole-food vitamin C source.
Reducing oxidative stress and inflammatory markers beyond what vitamin C alone provides — limited evidence. A small trial in smokers found camu camu juice reduced oxidative stress and inflammatory markers more than an equivalent dose of isolated vitamin C, suggesting other plant compounds in the fruit may contribute. This is a genuine but small, short, single-population finding that needs replication.
Broader claims like immune enhancement, skin benefits, or weight management — insufficient evidence. These claims circulate widely in supplement marketing but aren’t supported by dedicated human trials — they largely extrapolate from camu camu’s vitamin C and antioxidant content rather than being directly tested.

Typical dose

1–3 teaspoons (about 5–15g) of powder per day, providing roughly 500–2000mg of vitamin C depending on concentration

Upper limit: The tolerable upper intake level for vitamin C is 2,000mg/day from all combined sources

Timing

Take with food; check the specific vitamin C content per serving, since it varies widely by product.

Time to effect

Hours to days: Blood vitamin C levels rise within hours to days of intake.

Common myth

"Camu camu is a superfood cure-all that vastly outperforms regular vitamin C." In reality: Its vitamin C concentration really is exceptional, and one small trial found an extra antioxidant benefit over plain vitamin C in smokers — but broader superfood claims go beyond what dedicated human research has tested.
