Beta Glucans extracted from yeast cell wall
are non-specific immune response potentiators that
cross kingdom lines (plant, animal, human, etc).
The NSC site list hundreds of studies at Harvard,
Tulane, Baylor and many more that demonstrate very
positive results (DiLuzio, Browder, Czop, Patchen
as examples)for Beta Glucans. Even the one study quoted is
neutral; not negative.
Beta Glucans from oats/barley are Beta 1,4 glucans
that are effective against cholestorol but do not
potentiate the immune system. While Beta glucan
from mushrooms has immune enhancement capabilities,
Beta Glucan extracted from yeast cell wall is up to
50 times more effective.
Beware of Beta Glucan products that are whole yeast
cell walls (Solgar & others)without the Beta glucan
extracted. Similar to swallowing a can with food
product inside. Cheap but for a reason.

Also, if a University is quoted as certifying a Beta
Glucan product as pure, call the University. As an
example, the University of Georgia does not certify
Beta Gold as 90+% pure, only a sample that was taken to
the University that was not even labeled as Beta
Gold.

Beta Glucans extracted from yeast cell wall are
demonstrated as non-toxic and safe in multiple
studies. I have recently become president of NSC
and by that position am prejudiced about the
product. I have been involved with Beta Glucans
on a research, administrative and intellectual
property basis for years and will try to objectively
respond to questions about this product that
enables the immune system to better respond to
health invaders attacking us daily.
