Under FDA rule, a food label that bears the claim "MSG free," as well as the claims "No MSG," and "without MSG," but fails to meet the requirements of the rule is considered misbranded and subject to regulatory action by FDA.

Just as the FDA made Gluten-Free a rule for labeling, the same is needed for MSG.
