Strenght, why don't you try licorice. This can raise cortisol levels. Do not buy the deglyzerized (sp?) type if your adrenal fatigue is causing you to have low blood pressure. The ordinary licorice will help raise your BP. I open up a capsule in a cup of warm water with a pinch of sea salt and drink this first thing in the morning. Also make sure not to eat any sugar, not even fruit as sugar is veeeery bad for adrenals. Try to get to bed before 10 pm and try to lie in in the morning till 9 am. These times are for adrenal recovery. Make sure you eat a little protein with each meal, especially in the morning.

Again, if your blood pressure is low, try to have sea salt with every meal and then drink water in between. Ordinary table salt is bad, so stay far away from processed food. Sea salt is of benefit for those with adrenal fatigue.

Vitamin C is supposed to be good for adrenals, but since you have low cortisol perhaps you should not take this supplement as I have read it lowers cortisol levels.
