No, the “S” is sodium. MSG (monosodium glutamate) is a sodium compound like salt, but the anion is different - for salt it’s chloride, for MSG it’s glutamate.
It could be theoretically possible that only the anion caused you some hard. For example, sodium cyanide is extremely poisonous, but also a sodium salt. In practice however glutamate is just some aminoacid.
