Most box and can chicken broths are loaded with MSG or a very similar ingredient (even the unsalted), it is disguised under a variety of different names.

I prefer to boil a small chicken once a month or so, debone, defat, freeze individual chicken portions and broth servings.
It’s a lot of work but cost effective and I don’t have to worry about junk chemicals.

PS: If you must use the box stuff, check the natural food section of your market for organic brands……….however, they will cost more.
