MSG - by every other name

Following is a list of ingredients which either absolutely contain MSG or which often create MSG during processing:

Monosodium glutamate
Monopotassium glutamate
glutamic acid
calcium caseinate
sodium caseinate
hydrolized corn
textured protein
natrium glutamate
natural pork flavoring
bouillion and broth
soy sauces, extracts and proteins
flavors and flavorings
natural flavors and flavorings
hydrolized vegetable proteins
autolyzed yeast
hydrolized yeast
yeast extract
protein isolate
malt extract
barley malt

These ALWAYS contain MSGGlutamate
(E 620) Glutamic acid

(E 621) Monosodium glutamate

(E 622) Monopotassium glutamate

(E 623) Calcium glutamate

Monoammonium glutamate (E 624)

Magnesium glutamate (E 625)

Natrium glutamate (natrium is Latin/German for sodium)


Calcium caseinate

Sodium caseinate

Textured protein

anything “hydrolyzed”

any “hydrolyzed … protein”

Yeast nutrient

Yeast extract

Yeast food

Autolyzed yeast



These OFTEN contain MSG or create MSG during processing

Malt extract
Natural pork flavoring
Citric acid
Malt flavoring
Bouillon and Broth
Natural chicken flavoring
Soy protein isolate
Natural beef flavoring
Soy sauce
Barley malt
Soy sauce extract
Whey protein concentrate
Soy protein
Whey protein
Soy protein concentrate
Whey protein isolate
Protease enzymes
Anything protein fortified
Flavors(s) & Flavoring(s)
Anything enzyme modified
Anything fermented
Natural flavor(s) & flavoring(s)
Enzymes anything
Seasonings (the word “seasonings”)

These ingredients work synergistically with MSG to enhance
(If they are present for flavoring purposes, so is MSG)

Disodium 5’-guanylate
(E 627)

Disodium 5’-inosinate
(E 631)

Disodium 5’-ribonucleotides
(E 635)

The not so new game is to label hydrolyzed proteins as pea protein, whey protein, corn protein, etc. If a pea, for example, were whole, it would be identified as a pea. Calling an ingredient pea protein indicates that the pea has been hydrolyzed, at least in part, and that processed free glutamic acid (MSG) is present. Relatively new to the list are wheat protein and soy protein.

Disodium guanylate and disodium inosinate are expensive food additives that work synergistically with inexpensive MSG. Their use suggests that the product has MSG in it. They would probably not be used as food additives if there were no MSG present.

MSG reactions have been reported from soaps, shampoos, hair conditioners, and cosmetics, where MSG is hidden in ingredients that include the words “hydrolyzed,” “amino acids,” and “protein.”

Low fat and no fat milk products often include milk solids that contain MSG and/or contain Carrageenan, guar gum, and/or locust bean gum. Low fat and no fat versions of ice cream and cheese may not be as obvious as yogurt, milk, cream, cream cheese, cottage cheese, etc., but they are not an exception.

Protein powders contain glutamic acid, which, invariably, would be processed free glutamic acid (MSG). Amino acids are not always listed on labels of protein powders.

Drinks, candy, and chewing gum are potential sources of hidden MSG and/or aspartame and neotame. Aspartic acid, found in neotame and aspartame (NutraSweet), ordinarily causes MSG type reactions in MSG sensitive people. Aspartame is found in some medications, including children’s medications. Neotame is relatively new and we have not yet seen it used widely in the United States. Check with your pharmacist.

Binders and fillers for medications, nutrients, and supplements, both prescription and non-prescription, enteral feeding materials, and some fluids administered intravenously in hospitals, may contain MSG.

According to the manufacturer, Varivax–Merck chicken pox vaccine (Varicella Virus Live), contains L-monosodium glutamate and hydrolyzed gelatin, both of which contain processed free glutamic acid (MSG) which causes brain lesions in young laboratory animals, and causes endocrine disturbances like OBESITY and REPRODUCTIVE disorders later in life. It would appear that most, if not all, live virus vaccines contain some ingredient that contains MSG.
