Camu camu (Myrciaria dubia) is a fruit native to the Amazon rainforest, renowned for its exceptionally high vitamin C content. Its use in supporting or treating influenza is primarily grounded in its nutritional profile, particularly its antioxidant and immune-boosting properties. Scientific studies indicate that vitamin C can support the immune system, potentially reducing the severity and duration of respiratory infections like influenza. Some in vitro and animal studies have shown that camu camu extracts possess antioxidant and anti-inflammatory properties, which may help modulate immune responses during viral infections. However, direct clinical evidence specifically linking camu camu supplementation to prevention or treatment of influenza in humans is lacking.

A few small-scale human studies suggest that camu camu juice may reduce markers of oxidative stress and inflammation, which are relevant in the context of viral infections. Despite this, most research focuses on general immune health rather than specific anti-influenza effects. In traditional Amazonian medicine, camu camu has been used for overall wellness and to fend off colds, but influenza-specific historical use is not well documented. In summary, while camu camu’s vitamin C content provides a rationale for supporting immune function during influenza, robust scientific validation for its use against influenza itself is currently limited.
