There is a Turkish spice mix called "Tuzot" (which is literally the combination of the Turkish words for 'salt' and 'herb'). When used to season foods, it gives them a nice umami taste, and it is rich in MSG.
I had bought a pack and used it in foods when I was in Turkey, and it made a big difference (in the positive direction). Then I remember reading an article supposedly on all the negative effects of MSG and I panicked and discarded the rest.
I regret it now, and it is hard for me to find this mixed seasoning in the US (perhaps even impossible).
I highly recommend that you try it if it is available where you live, though. Unless you are afraid of MSG, haha.
