No, The subject of whether Braggs aminos contains MSG is one that comes up quite often. This popular liquid seasoning contains no added monosodium glutamate, but it does contain a naturally occurring form of it called free glutamic acid. Because of the source and other factors, Braggs claims its product does not add to the body's glutamate load like MSG from other sources may do, meaning that it is considered to be safe for most people. Despite this mainstay in most kitchen cabinets, if you are seeking to avoid this compound completely, double-check the label carefully before purchasing and consuming any product.
