Larch Arabinogalactan
Larch Arabinogalactan: your immune system’s communication booster.
Derived from the larch tree (Larix species), arabinogalactan is a powerful prebiotic fiber with unique immune-modulating properties. If zinc is the strategist and electrolytes are the command center, larch arabinogalactan is like the immune system’s messaging network—allowing immune cells to coordinate efficiently, detect threats early, and mobilize the right response with precision.
Here’s why we love larch arabinogalactan for immune health:
Enhances natural killer (NK) cell activity, supporting rapid immune defense against viral-infected cells.
Stimulates macrophages—the immune system’s front-line scavengers, helping them engulf pathogens more effectively.
Promotes production of short-chain fatty acids (SCFAs) in the gut, improving gut-immune signaling and supporting anti-inflammatory balance.
Supports beneficial gut microbes, making it a gentle prebiotic that strengthens the microbiome’s role in immunity.
Encourages healthy mucosal immunity, improving defenses across the respiratory, digestive, oral, and sinus tissues.
Well tolerated with a low side-effect profile, even when taken regularly for ongoing immune resilience.
Evidence-based research findings:
Larch arabinogalactan enhances immune cell function, particularly NK cells and macrophages.
It increases production of SCFAs such as butyrate, which improves gut immunity and reduces inflammatory burden.
Supplementation has been shown to reduce incidence of common respiratory infections in both adults and children.
Its prebiotic effect positively modulates the microbiome, indirectly supporting systemic immune strength.
It supports mucosal barrier immunity—the body’s first line of defense against airborne and gastrointestinal pathogens.
