Camu Camu and Immunotherapy: The Prebiotic Power of Castalagin

The Amazonian Camu Camu fruit is revered for its astonishing concentration of Vitamin C, but its potential role in advanced health research is even more compelling. The focus of recent studies is on the fruit’s powerful polyphenols, especially the compound known as Castalagin.


The Science of Castalagin and Cancer Support

Is Camu Camu a proven treatment against cancer? Not yet. But the science is incredibly promising.

A major 2022 study by the Faculty of Medicine of Montreal found that Castalagin, a polyphenol isolated from the Camu Camu berry, works as a potent prebiotic in preclinical models. This means it acts on the gut microbiome.

  •      •   The Mechanism: Castalagin shifts the gut’s microbial composition to favor bacteria (like Ruminococcus bromii) associated with a more robust immune response.

  •      •   The Result: In mice, this shift translated into significant antitumor activity and improved the efficacy of anti–PD-1 drugs (a type of cutting-edge immune-checkpoint inhibitor, or ICI).

The research provides a strong biological rationale for using Castalagin as a complement to existing immunotherapies, even in cases where resistance is present. The discovery is currently being tested in human clinical trials, which is the necessary next step to confirm these beneficial effects in patients.


The Lyophilization Difference: Preserving Potency

The difference between a standard fruit powder and a lyophilized (freeze-dried) product is everything when dealing with sensitive nutrients.

Lyophilization is the gold standard for preservation because it operates at extremely low temperatures and under a vacuum.

  • Nutrient Retention: This process preserves the intact nutritional composition of the fruit, retaining up to 97% of vitamins, antioxidants, and phytochemicals, including the heat-sensitive natural Vitamin C and the polyphenol Castalagin.

  • Thermal Damage: Any standard process that uses heat to dry and grind fruit for powder production will inevitably destroy the natural Vitamin C and compromise the structure of polyphenols.

Our new product, Nuestra Camu Camu, Lyophilized Camu Camu Pulp in capsules, is a testament to this commitment to purity. It is the only way to ensure you are receiving the real values of the strongest known antioxidant and the promising effects of Castalagin.
