Salt Monosodium Glutamate

Monosodium glutamate (MSG) is the sodium salt of glutamic acid, an amino acid found naturally in many foods. It is produced industrially through the fermentation of carbohydrates, similar to how yogurt or wine is made. MSG provides a savory or umami taste.

Manufacturers add MSG to foods to enhance their savory (umami) flavor. It is commonly found in processed foods like chips, snack foods, salad dressings, canned soups, and frozen meals. It can also be used in seasoning blends and spice mixes.

MSG is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA). Some individuals report sensitivity to MSG, experiencing symptoms like headaches or flushing, though controlled studies have not consistently linked these symptoms to MSG consumption at typical levels. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated MSG, with no numeric acceptable daily intake (ADI) specified by JECFA. Evidence on adverse effects remains mixed.
