What Is Arabinogalactan?
Arabinogalactan, or AG, is a fermentable fiber found in
high concentrations in North American larch trees. It is
also the active constituent of echinacea. AG has
demonstrated the ability to activate immune cells
involved with the body's first line of defense and to
promote cytokine production, the communication and
signaling compounds of immune cells. Antioxidants, such
as vitamin C, may enhance arabinogalactan activity.*
Uses For Arabinogalactan
Research conducted at the University
of Minnesota revealed that AG stimulated immune cells
with a higher capacity than echinacea. In several
university studies at major U.S. institutions, AG promoted
immune cell function in humans. A recent, randomized
4-week trial in healthy adults showed that AG also
potentiates the complement system, another mechanism
of defense in the body.*
Support For Healthy Microflora Levels:
human studies also indicate that AG supports a healthy
environment for the colon. In the colon, AG enhances the
growth of the friendly microflora lactobacillus and
Source for Arabinogalactan
