Larch Arabinogalactan Interactions Overview

Arabinogalactans are long, densely branched, high-molecular weight polysaccharides found in many plants, with the highest concentrations in larch trees. Larch arabinogalactan, specifically obtained from the western larch (Larix occidentalis) and eastern larch (Larix laricina), is approximately 98% arabinogalactan. This polysaccharide has a range of potential health benefits, including serving as a soluble, non-viscous fiber that ferments in the gut, potentially increasing beneficial gut bacteria like Lactobacillus. Additionally, larch arabinogalactan has been investigated for its possible role in drug delivery systems due to its water solubility and numerous hydroxyl groups, which may enhance the bioavailability of drugs like ibuprofen. Moreover, preliminary research suggests immunostimulatory effects, such as increased natural killer cell activity and enhanced immune response to certain vaccines.
