Note:  To lower cortisol, I feel the best way to go is phosphatidylserine (PS), Remeron (mirtazapine) and/or Avandia (rosiglitazone) although there is only one study on mice that I know of with Avandia.  An effective PS dose of 800 mg per day lowered cortisol in one study by 30%.  However that amount runs about $6 per day.  See my dedicated page on the only study I've seen regarding Remeron (an antidepressant).  Click here for articles on Avandia.  Remeron and Avandia are available through OffshoreRX.combut check with a doctor before taking any supplement or medication.  Avandia is also available through SuperSaverMeds.com.

A new product, Relora at 750 mg/day has been shown to reduce cortisol by 37%.  See Vitamin Shoppe.  For phosphatidylserine, see Vitacost, iHerb and Vitamin Shoppe.  I tried Relora and didn't at all like the way it made me feel.  CortiSlim is also available at Vitamin Shoppe or drugstore.com.  Also,  Relacore at drugstore.com and Cortisol formulas at iHerb.  I feel these formulas may be designed my the accountant though.

I was watching Dr. Perricone anti-aging lectures on PBS in late August 2002 and he claims that DHEA can help protect the brain from the negative effects of cortisol.  I take 50 mg/day of the 7-keto DHEA.

  become suicidal.
  
  They have very, very disturbing and crazy thoughts ... and they have no ability to suppress them,� said Joseph K. Belanoff, a California psychiatrist who is chief executive officer of Corcept Therapeutics Inc., a small pharmaceutical company. Corcept is sponsoring a study of RU-486 for psychotic depression.
  
  Several lines of evidence have led researchers to suspect that some of the symptoms of psychotic depression are caused by an excess of cortisol in the brain. Cortisol levels rise in response to stress and may be abnormally elevated in depressed individuals. Similar symptoms can occur in patients with Cushing's syndrome, an overabundance of cortisol usually caused by a tumor, and RU-486 has cured the mental disturbance in some
  such cases.
  
  Our feeling has been that a lot of the cognitive problems and delusions that you see in some of the patients are due to the [cortisol],� said Alan F. Schatzberg, chairman of the psychiatry department at Stanford University School of Medicine, where researchers are conducting a study that will test RU-486 on 30 patients with psychotic depression.

This reaction stimulates the release of cortisol from the adrenal cortex. In turn, cortisol, a glucocorticoid, stimulates glucose release into the bloodstream, which, during periods of chronic stress, creates an excessive release of insulin. Insulin, which is part of the endocrine system, is a fat-storage hormone that overrides the stress signal from adrenalin to burn fat. The excess release of insulin gives the body the message to store fat in the abdomen"
