Is MSG bad for you? What the FDA says about monosodium glutamate and the label.

Updated

What the FDA says about MSG safety, the short-term symptoms some people report, how MSG must be labeled, why yeast extract is not MSG on a label, and catalog products that list monosodium glutamate.

Quick answer

The FDA considers MSG generally recognized as safe (GRAS). It has received reports of headache and nausea after eating foods with MSG but has never confirmed MSG caused them. In studies where people who believe they are sensitive were given MSG or a placebo, scientists could not consistently trigger reactions. The FDA cites a report describing short-term, mild symptoms in some sensitive people who consume 3 grams or more without food, while a typical serving contains under 0.5 grams of added MSG.

What the FDA says about safety.

The FDA considers adding MSG to foods generally recognized as safe. It reports receiving complaints of headache and nausea after eating MSG-containing foods but says it never confirmed that MSG caused them. It cites a FASEB report that described short-term, mild symptoms, such as headache, numbness, flushing, tingling, palpitations and drowsiness, in some sensitive people who consume 3 grams or more of MSG without food, and notes a typical serving has under 0.5 grams of added MSG, so consuming more than 3 grams without food at one time is unlikely.

What the studies found.

The FDA says that in studies where self-identified sensitive individuals were given MSG or a placebo, scientists could not consistently trigger reactions. That is the extent of the evidence we cite here; the FDA page does not describe a long-term harm finding for MSG.

How MSG must be labeled.

Foods with added MSG must list it as “monosodium glutamate”; it cannot be hidden under “spices” or “flavoring”. Other glutamate salts such as monopotassium glutamate and monoammonium glutamate must also be declared by name. Ingredients such as hydrolyzed vegetable protein, autolyzed yeast, yeast extract and soy extracts naturally contain free glutamate, and labels are not required to say so, but products with them cannot claim “No MSG” or “No added MSG”.

What this checker flags.

CleanFoodScore flags explicit monosodium glutamate or MSG only. It does not flag yeast extract or hydrolyzed protein, so if you avoid all added free glutamate, read for those too. The products below name monosodium glutamate on their recorded label, picked across shelves; open any for the full statement and verification date.

How the clean score works

No setup needed, and strict: a full 100 needs every additive group clear and a verified organic claim (animal foods also need a verified grass-fed or pasture-raised claim; wild seafood and salt, which have no USDA organic standard, are scored without the organic points, and plant-based milks, cheeses and proteins without the feeding claim). Points: the nine additive groups (seed oils, artificial dyes, MSG, artificial sweeteners, carrageenan, artificial preservatives, hydrogenated oils, corn syrups, banned-abroad additives) share 60 points equally — not found earns a group’s full share, “may contain” earns half, listed earns 0; a verified organic claim is worth 25; a verified grass-fed or pasture-raised claim is worth 15 and counts only for animal foods. No claim, or an expired or unverified claim, earns nothing, so products without those claims cannot reach 100. Unverified or expired ingredient labels receive no score. Equal scores are equal. Ties are ordered by brand. Unknown and stale evidence never passes “Only show matches.” Producer claims and prices do not affect this score. This is not a nutrition, allergy, or safety rating.
