If all the pregnenolone is being used to make cortisol no other steroids are made. Vitamin D is one of those steroid hormones........this is called pregnenolone steal syndrome. More over when someone cortisol is up that hormone completely shuts the immune response off.......chronically it also turns off the thyroid by increasing reverse T3 which is a direct inhibitor of T3. Now for the ultimate off valve........if your thyroid is turned off.......you can't make pregnenolone from cholesterol at all ........because that conversion requires thyroid hormone and vitamin A to happen.........this worsens the pregnenolone steal syndrome and we see every other
hormone made from pregnenolone shut off. This is why leptin resistance resistance is associated with global decreases in sex steroids immunity and poor sleep with horrible energy balance...............and using leptin is how the brain oversees energy utilization and use for our 20
trillion cells to keep us fit..............
