The immune system is a highly complex and interrelated system that has two pathways to address foreign substances: the innate, non-specific arm that targets anything viewed as foreign to the body; and the adaptive system that targets specific foreign substances. These work in tandem to protect the body against foreign substances. Lonza Group Ltd. developed ResistAid as a proprietary, natural immune-support ingredient with the ability to modulate and support appropriate immune response. Produced via a patented, solvent-free (steam-heating), water-based extraction process from larch trees that grow in abundance in the U.S., ResistAid consists of the soluble fiber arabinogalactan and bioactive phenolic flavonoids, with strong antioxidant capacity for “triple action” immune support (direct, indirect and via its antioxidant mechanism). It is GRAS/FDA-approved as a direct food additive, non-GMO, kosher-certified and manufactured allergen-free, according to HACCP principles, and GMP-audited by American Institute of Baking. The product remains pure and structurally unaltered after extraction. ResistAid helps increase beneficial immune cell populations and/or increasing antibody production, based on the immune stressor, supporting the immune-cell system of macrophages, neutrophils and natural “killer” lymphocytes; modulation of immunoglobulin G antibodies; and the cytokine system of interferon gamma, tumor necrosis factor alpha, interleukin-1 beta and interleukin-6.
