Monosodium glutamate no longer GRAS?

On November 15, 2011, Truth in Labeling co-founder Jack Samuels suffered a massive heart attack. He died on January 15, 2012 from heart damage exacerbated by complications caused by MSG — MSG in the electrode tabs applied to his skin; MSG in the dextrose solution used to deliver the drugs that would crystallize in the non-MSG Ringer’s solution and MSG in the starch and cornstarch components of the medications given to him when the IVs were withdrawn.

Had the FDA not lied about the toxic potential of MSG, had the medical community not believed them, had the MSG in the solutions and meds been identified on product inserts, Jack might be alive today. Had Jack not spent half of the last quarter of his life fibrillating following ingestion of MSG hidden in food, he might not have had the heart attack in the first place.

On January 4, 2021, I filed a Citizen Petition requesting that the FDA discontinue representing the interests of those who manufacture monosodium glutamate (MSG) – that the public be told the truth about the toxicity of MSG and its excitotoxic, brain damaging L-glutamic acid. FDA Commissioner Stephen M. Hahn, M.D. has been asked to revoke the GRAS (generally recognized as safe) status of MSG and L-glutamic acid for any use in human food.

Copies of the Petition from the FDA are available here. (To read or comment, simply insert the petition docket number FDA-2021-P-0035 in the space provided and use the “comment now” button). The petition and related material are also available at the webpage of the Truth in Labeling Campaign.

The petition contains a Statement of Grounds providing evidence of the need for revoking the GRAS status of MSG and L-glutamic acid for use in human food.

Details pertaining to the toxic effects of MSG, FDA/industry liaison, industry protocols used for production of negative results, and suppression of information can be accessed at these respective links.

If you have questions or comments other than those for the FDA please email me at

But of greatest importance, please tell the FDA that MSG should be stripped of its GRAS status, and search out others to do the same, by commenting to the FDA on the Citizen Petition:

Thank you for caring.
