Can Dr. Peat’s Progest-E Complex help PTSD? That’s really a question for your qualified physician and Progest-E is not designed to treat PTSD per se.
That said, progesterone in general has neuro-protective qualities. And its recognized properties of being anti-excitatory and stabilizing to the brain, would suggest that it could be helpful.
The basic problem is a poor estrogen-progesterone ratio favoring estrogen which creates a sense of anxiety whether there has been an initial trauma or not. An excessive estrogen/progesterone ratio (should be 1 part to 10 parts, estrogen to progesterone), is involved in producing aggravating symptoms such thin, bluish skin.
Excess stress (which can block progesterone synthesis and elevate estrogen) may bring on symptoms in someone who never had them. As well as darker days without sun, toxins and nutritional deficiencies. A very common cause of an estrogen excess is a dietary protein deficiency because the liver cannot detoxify estrogen when it is under nourished.
