Here is the email I received from the COO of the company that makes Emergen-C:

Thank you for your support of Emergen-C and for sharing your concerns. 

I just want to clarify that we do not process any gluten-type ingredients 
here at our facility...the traces of wheat found in Raspberry & Mixed Berry are 
from our ingredient supplier - that's why only traces were found. 

In testing, there were no traces found in any of the other flavors, but just 
to be overly safe, we share that all flavors are processed in the same 
facility. 

As an alternative, our tablet line is gluten free, and Super Gram III is 
closest in formulation to Emergen-C. For more information on Super Gram III, 
please visit our website at http://www.alacer.com/.

Kindest regards,

Also, a number of people responded that they take Emergen-C without a 
problem.  One person emailed that they take the raspberry flavor (which says it has 
wheat in it on the box) without a problem.

Also, someone suggested ALL-ONE powdered vitamins and said they have a 
website.
