Beta Glucan is a polysaccharide found in barley and whole oats. Arabinogalactan is a water-soluble polysaccharide found in many foods such as carrots and radishes. However, uniquely high concentrations of this fiber are found in the bark of the western Larch Tree (Larix occidentalis), the source of Immunity Booster's Arabinogalactan. Beta Glucan helps increase the amount and activity of immune cells, the body's first line of defense.* Arabinogalactan has been shown to have a positive impact on the human immune system.* Human studies, conducted at several major U.S. universities, showed increased immune cell proliferation at consumption levels of about 1500 mg of Arabinogalactan per day, the precise amount found in Twinlab Immunity Booster.
