Arabinex® supports healthy immune function and can help optimize intestinal bacteria.* 

Thorne’s Arabinex consists of larch arabinogalactans, polysaccharides that are derived from Larix occidentalis, the Western larch tree. This mild tasting, highly soluble powder mixes easily with water or juice, so it’s an ideal supplement for both adults and children. Larch arabinogalactans possess important immune-suporting properties and are an excellent source of fiber.*

As a prebiotic, Arabinex can help increase beneficial bacteria in the colon to support intestinal health.* Its use can also help increase short-chain fatty acids – mainly butyric acid – the primary fuel for the colonocytes – the cells of the large intestine.* Butyric acid is produced in the colon by the fermentation of fiber, such as the fiber provided by arabinogalactans. High levels of butyrate in the colon help provide a healthy colonic environment.*
