ARABINOGALACTAN is a polysaccharide produced from the bark of the Larch tree. Arabinogalactans are found throughout nature and are found in other plants with immune support activity. Larch arabinogalactan is a fibrous product which ferments in the gut. It increases gut microflora, e.g. Lactobacillus, increases short-chain fatty acid production, and minimizes ammonia production and absorption. These effects suggest it may be beneficial as a dietary fiber supplement for improving gastrointestinal health. A normal functioning and healthy gastrointestinal tract also supports immune function. Larch arabinogalactan has been shown to concentrate in the liver.
