Using OpenLinkMap, I identified most of the current GNC outlets mapped in the US and recorded the key:shop values ... all of the variants appeared once; if more than once, the number is in parentheses:

Looking at the wikipedia article, "GNC (store)", the informative categories used are "health food stores" and "nutrition".  Looking in TagInfo shows that the value "health_food" is available for key:shop at about rank 170 with 57 uses; "nutrition" shows up as three items in TagInfo, "nutrition" (20), "nutrition_supplements" (3) and "nutritional_supplements" (1).

This is what I'll do on the shop I'm putting in now, but I wanted to bring this out to stimulate conversation on whether or not a guideline of consistent baseline tagging for stores in a chain might be beneficial to the OSM dataset or not.  The Wiki could be used to store the outcomes of discussions here.

Yes, this is a common problem in OSM. I first noticed it when I went
to tag my local Staples. I've had thoughts about creating some kind of
template on the wiki to document chain stores and what tags to use on
them but... well, I haven't run out of things to map yet so the time I
spend on the wiki isn't all that great.

As for using two values, I would discourage that. In theory that's a
great way to use two values for one key but in practice pretty much
nothing parses and supports multiple tag values. So I usually just
pick one and go with it.
