Larix occidentalis

Immune Modulatormoderate evidence

Arabinogalactan from Western Larch tree is one of the most potent natural NK cell activators known. It stimulates macrophages, NK cells, and T-lymphocytes through TLR pathway activation, enhances interferon-gamma production, and inhibits metastasis of cancer cells to the liver. As a soluble fibre it powerfully supports the gut microbiome.
