The glutamate industry andcompanies, including pharmaceutical firms, that wish to use processedfree glutamic acid (MSG) in their products, improperly claim that theterm "MSG" only applies to the food ingredient "monosodiumglutamate."

They pretend not to realizethat "monosodium glutamate" is nothing more than glutamic acidthat has been freed from protein through a manufacturing process (processedfree glutamic acid), salt (sodium), and moisture. It is the processedfree glutamic acid that MSG-sensitive people react to, providing thatthey ingest amounts that exceed their tolerances for the substance.

Consumers may react to processedfree glutamic acid that is contained in any food ingredient or product,including AuxiGro, regardless of the name of the ingredient or product.

Because MSG-sensitive peoplemay react to all ingredients and products that contain processed freeglutamic acid, they refer to such ingredients and products as containing"MSG."

In August, 1995, the Food andDrug Administration (FDA) noted in a document entitled the "FDA Backgrounder"that consumers frequently refer to all [free] glutamic acid as "MSG."The "FDA Backgrounder" is still in use by the FDA and can likelybe found on their Web site.

Based on peer reviewed studies,there is no question that glutamic acid is neurotoxic. This can be easilyconfirmed by accessing MEDLINE retrieval service for studies dating from 1966 to the present, using thewords "glutamic acid" in combination with the words "brainlesions" and then "neurotoxicity." I would also suggestthat you look up the words besity," " and "seizures"combination with the words "glutamic acid."

There is also no question thatthe young are most at risk from MSG. To confirm this, you might startby reviewing the work of John W. Olney, MD and look up the words "glutamicacid" in combination with the words "blood brain barrier"and "placental barrier."

You will learn that the bloodbrain barrier is not fully developed in the young to protect against toxinsthat enter the blood, and that glutamic acid can also penetrate the placentalbarrier.

Disregarding the blood brainbarrier and the placental barrier issues, the literature clearly indicatesthat, based on the amount of MSG used in the 1970s, over25% of the population react to MSG.

Although we have not reviewedall vaccines used on infants, we have found one or two sources of processedfree glutamic acid (MSG) in those that we have information on. In discussionwith a retired executive of a company that produces vaccines, he suggestedto me that all viral vaccines would have free glutamic acid, used to feedthe live virus.

The glutamic acid in vaccinesare often described as "stabilizers," i.e., ingredients to keepthe virus alive. We describe them as a hidden source of processed freeglutamic acid (MSG).

An example for you would bethe Chickenpox Vaccine by VariVax -- Merck & Co., Inc. (Merck). Thisvaccine includes "L-monosodium glutamate" and "hydrolyzedgelatin."

Another example would be Merck'sM-M-R vaccine. The product insert states that the growth medium for measlesand mumps includes "amino acids" and "glutamate."It is also stated that the medium for rubella included "amino acids"and "hydrolyzed gelatin." Finally, it states that the "reconstitutedvaccine" for subcutaneous administration includes hydrolyzed gelatin.

We have no way of knowing whichamino acids are used in Merck's vaccines, but we do know that the aminoacids "glutamic acid," "aspartic acid," and "L-cysteine"are neurotoxic.

We also know that any hydrolyzedprotein, such as the hydrolyzed gelatin will contain some processed freeglutamic acid (MSG), some aspartic acid, and some L-cysteine, all consideredto be neurotoxic by neuroscientists. Even without hydrolyzing gelatin,gelatin contains over 11% processed free glutamic acid (MSG) and someaspartic acid and L-cysteine. It is present as a result of the manufacturingprocess that results in gelatin.

The product insert for M-M-Rvaccine by Merck provides a contraindication that states, in part: "Hypersensitivityto any component of the vaccine, including gelatin." It is footnotedto the following reference.

I cannot help but wonder ifat least some of the subjects in the study above reacted to gelatin. Mostreactions to processed free glutamic acid (MSG), as contained in gelatin,are not IgE mediated. They are best described as a sensitivity to a toxicsubstance.

If you wish to determine moreabout Merck vaccines, I would suggest you call their National ServiceCenter at (800) NSC-MERCK. Do not ask about the presence of "MSG"in vaccines. Rather, ask about the presence of "free glutamic acid."You will have a better chance of getting a reliable answer.

Not long ago, a vaccine forRotavirus came to market. The product, which contained some processedfree glutamic acid (MSG), carried a warning in the product insert thatit not be used for individuals who had a hypersensitivity to MSG. Shortlyafter the Rotavirus came to market, it was found that the vaccine resultedin digestive blockages, and the product was withdrawn from the market.

One last comment regardingthe exposure of infants to processed free glutamic acid (MSG): the presenceof processed free glutamic acid (MSG) in infant formulas.

We have found that major brandsof infant formula, if not allinfant formulas, contain some processed free glutamic acid(MSG). The hypoallergenic soy formulas containvery high levels of MSG. See for further detail.

It might be worthwhile forsomeone to do a study of people who were raised on hypoallergenic formulasto determine if they have experienced a higher incidence of obesity, learningdisabilities, and/or ADHD, in childhood and/or endocrine disorders laterin life, as compared with people who were breast fed, and then as comparedwith people who were raised on milk based infant formulas.

If I can be of any furtherhelp to anyone on this important subject, they should not hesitate towrite or call. If anyone receives a list of ingredients from vaccine producers,I would be pleased to go over the ingredients and advise them of the ingredientsthat contain processed free glutamic acid (MSG).
