About Myrciaria dubia
Camu camu is an Amazonian fruit with an unusually high natural vitamin C content (~2,000 mg/100g fresh fruit). A small human study in smokers found whole-fruit camu camu reduced oxidative-stress and inflammatory markers more than an equivalent dose of synthetic vitamin C alone, suggesting a whole-food polyphenol effect beyond vitamin C; a small 2024 trial reported reduced liver fat in NAFLD after 12 weeks. Evidence base is still limited to a small number of human studies, not meta-analyzed.
What Myrciaria dubia supports
- Very high natural vitamin C source with some antioxidant benefit shown beyond vitamin C alone — based on a small number of human studies, not yet a large evidence base
How much Myrciaria dubia to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
500–3000
mg
Whole-fruit powder dosing; vitamin C yield varies widely by processing (roughly 2-3% of dry weight), so labeled vitamin C content should be checked directly rather than assumed from this range.
Clinical evidence
Limited clinical evidence. A handful of small human studies support antioxidant/metabolic effects; not yet replicated at scale or meta-analyzed.
