Ephedrine sulfate question

I just picked up a bottle of Bronkaid at my local grocery store which contains 25 mg. of ephedrine sulfate (along with guaifenesin). I seem to recall in an old Dan Duchaine column that the sulfate is more bioavailable than the HCL form. Is anyone more familiar with this? I’m assuming I didn’t just throw money down the drain. It is the ephedrine sulfate, not the pseudo.
