I spoke with Customer Service from Alacer Corp today.  They make  Emergen-C
packets that have Vit C & other vitamins that you pour into water  to make a
"Vitamin C Fizzing Drink".

The rep told me that all the Emergen-C packets-- except raspberry--  have
been tested & found to contain no traces of wheat, rye, or  barley.  The
raspberry flavor was tested & is not GF.  I'm  not certain if there are any
contamination issues between the raspberry and the  other flavors.
