Larix occidentalis
North American larch tree extract as prebiotic immune enhancer and NK cell activator.
Larch Arabinogalactan is a soluble fiber extract from the Western Larch tree (Larix occidentalis), used as a prebiotic to support gut health and modulate immune function. Its primary active compound is arabinogalactan, a polysaccharide that enhances natural killer (NK) cell activity, along with flavonoids such as taxifolin, quercetin, and resveratrol. Clinical evidence, though limited, suggests benefits in reducing the incidence of pediatric upper respiratory infections and supporting overall immune defense.
Arabinogalactan acts as a prebiotic by selectively stimulating the growth of beneficial gut bacteria (e.g., Bifidobacteria, Lactobacillus), which in turn enhances mucosal immunity. It also directly activates macrophages and NK cells through binding to lectin receptors (e.g., dectin-1) and toll-like receptor 4 (TLR4), leading to increased production of cytokines such as IL-12 and IFN-γ. The flavonoid components provide additional antioxidant and anti-inflammatory effects via inhibition of NF-κB and modulation of COX-2 pathways.
