Oxidative stress, produced either by tumors or by certain types of immune cells, is extremely toxic to NK cells and cytotoxic lymphocytes, impairing their tumor-killing capacities and even killing them (19-21). Most of this oxidative stress is generated by the NADPH oxidase enzyme complex (22,23). A key phytonutrient found in spirulina, phycocyanobilin, can function as a potent inhibitor of this enzyme complex, going to the root of oxidative stress (24). That’s one key reason why we include dietary spirulina – provided by our product Chocolatl Verde – in the At-Home regimen. Moreover, like probiotic bacteria, spirulina contains cell wall polysaccharides that have been shown to stimulate immune-supportive dendritic cells (25,26). And you will recall that, by inhibiting NADPH oxidase, spirulina can act directly on some cancer cells to slow their growth and spread, and can also interfere with the angiogenic process (23,27). So spirulina appears to work in at least four complementary ways to slow tumor growth and support the immune rejection of tumors.
Another agent with likely benefit in this regard employed by Oasis of Hope is the amino acid glutamine, provided in our product GPG. Glutamine functions as a key source of calories for immune cells.
