MSG (monosodium glutamate, E621) is halal. It is produced by fermenting plant carbohydrates — sugar cane, sugar beet or corn starch — so it is not animal-derived. The only caveat some scholars raise is confirming that no haram substance is used in processing, but mainstream MSG is considered halal. The old health scares around MSG are a separate matter from its halal status.

What MSG is
MSG (monosodium glutamate, E621) is a flavour enhancer that adds savoury "umami" taste. It is common in snacks, seasonings, instant noodles and restaurant cooking.
How it's made
Modern MSG is produced by fermenting plant carbohydrates — sugar cane, sugar beet or corn starch — much like yogurt or vinegar is fermented. It is not derived from animals, which is why it is generally considered halal.
The one caveat
Some scholars class E621 as mushbooh (to verify) only in the sense that, in principle, one should confirm no haram processing aid such as alcohol was used. In practice, mainstream commercial MSG is treated as halal, and halal-certified MSG is available.
A note on the health scare
The long-standing "MSG is bad for you" reputation is a food-safety debate, not a halal one — regulators consider MSG safe, and it does not affect the halal ruling either way.
