[at-l] New Study re glucosamine condroitin

[Mark Hudson]

<<*Hyaluronan* (also called *hyaluronic acid* or *hyaluronate*) is a
non-sulfated glycosaminoglycan<http://en.wikipedia.org/wiki/Glycosaminoglycan>distributed
widely throughout
connective <http://en.wikipedia.org/wiki/Connective_tissue>,
epithelial<http://en.wikipedia.org/wiki/Epithelial_tissue>,
and neural tissues <http://en.wikipedia.org/wiki/Neural_tissue>>>

That's the start of the Wikipedia description.
So my question is if it is also a glycosamine do you take it with
glucosamine sulfate or instead of...?
