MSG has been shown to overstimulate and damage neurons (nerve cells) in the hypothalamus region of the brain.  This part of the brain directs the action of the pituitary gland, which is called the "master" gland because it in turn directs the action of the other glands in the body - controlling metabolism, sexual development, and many other life processes.  25% of adults will develop a pituitary adenoma in their lifetime.  It is not officially known what causes them.  It does not appear to be genetically linked at this time. 


Almost half of all pituitary adenomas are prolactin secreting.  These prolactinomas can get so large that they affect vision by crowding the optic nerve.  In women, they are detected early because they interfere with menses.  Prolactin is the hormone associated with lactation in women who are nursing.   It stops ovulation.  Women with these tumors often can not become pregnant because the body already thinks it is.

In persons with a prolactin secereting tumor, lactation can take place even if:

1 The victim was never pregnant

2. The victim is MALE.

Men who develop these tumors can develop breasts which secrete milk.  For men this disease is often devastating and can become life threatening, since in men, there is often no warning until the tumor has become large enough to possibly affect vision, cause excruciating headaches, and threaten other vital functions of the pituitary.

Pituitary tumors are often "benign" - not cancerous.  Because of this, they are not tracked in registries that keep track of tumors.  The government is only concerned if a tumor is cancerous.  Aspartame, which was found to produce pituitary tumors in laboratory animals was approved for use.   There is no one actually tracking pituitary tumors in individuals who heavily use aspartame or MSG.

The cost of treating this illness is staggering.  The medication of choice - there are only two - is cabergoline which is a dopamine agonist sold under the name Dostinex.  It costs $30 per TABLET.  Even if patients undergo surgery, they usually must be on this medication for life.  This medication is the exact same one approved for use in Parkinson's patients who have decreased levels of dopamine in the brain.


  • MSG has been shown to increase prolactin secretion.

  • MSG had been shown to decrease dopamine levels in the brain. 

  • MSG has also been proven to cause sterility in females.  

  • Aspartame has been proven to cause pituitary tumors

  • Aspartate can be converted to glutamate in the body.  

  • Glutamate acts on the same receptors in the brain as aspartate.

  • One of the scientists contributing to this website who worked heavily with aspartame and ingested MSG in test products at the same time is currently taking Dostinex to treat a prolactin secreting pituiary adenoma.


Gamma Amino Butyric Acid (GABA) is created in the body from MSG.  It prompts the pituitary to release growth hormone.  However, excesses of hormone can actually shut down certain hormone regulated processes. Too much hormone is like a trouble signal that shuts things off.  In animal studies, MSG was shown to result in stunted growth.
