    PUFA Initiate & Promote The Stress Response (ACTH/cortisol), SFA Inhibit It

    Almost two years ago I posted a study showing that PUFA can stimulate cortisol release even in the absence of ACTH. Pufa Stimulates Cortisol Production Even In The Absense Of Acth However, that study above did not look at the effects of saturated fatty acids (SFA) and I keep getting emails...

    T4 Raises ACTH And Cortisol

    Thyroid hormone action on ACTH secretion. - PubMed - NCBI "Thyroid hormone effects on pituitary ACTH have not been well established. Adult male Sprague-Dawley rats were rendered hypo- and hyperthyroid while undergoing treatment with 6-Propylthiouracil (PTU) and L-Thyroxine (T4). At the time of...

    Pregnenolone Is The Most Potent Inhibitor Of The Stress Signal (CRH)

    I think this study should finally put to rest the arguments and debates of whether pregnenolone raises or lowers cortisol, and how it affects the stress response overall. I posted a similar study, which showed that the pregnenolone metabolites progesterone and allopregannolone potently inhibited...

    Pufa Stimulates Cortisol Production Even In The Absense Of Acth

    Many people opposing Peat have complained that there is no evidence for PUFA acting on the stress hormones or that oxidizing PUFA is bad for health. Well, this study not only shows otherwise but also demonstrates that a PUFA metabolite is capable of stimulating cortisol synthesis even in the...

    Clonidine Lowers Cortisol, ACTH And Overall Stress Response

    It is well known that clonidine lowers adrenalin, and Ray has written about it. It looks like clonidine is also able to restrain the other side of the sympathetic stress response - the ACTH, cortisol, hyperglycemia process. All studies below are in humans. So, it looks like clonidine may be a...
