Clinically proven ingredients. Nutritionally supports immune activity and response. Twinlab® Immunity Booster™ contains an exceptional blend of clinically proven ingredients including the precise amount of Arabinogalactan plus Beta Glucan that help support the body’s immune system function. Vitamin C and E also have been proven to help fight free radical damage while herbs elderberry and echinacea along with minerals zinc and selenium help empower a healthy immune system. That’s why Twinlab’s Immunity Booster is the solution for optimal health and wellness throughout the year. What are Beta Glucan and Arabinogalactan? Beta Glucan is a polysaccharide found in barley and oat wholes. 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. How does Beta Glucan and Arabinogalactan provide immune support? Beta Glucan increases natural killer cell activity, 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’s Immunity Booster.
Suggested Use: As a dietary supplement, take three capsules daily, preferably with food.
