What is the best one supplement to take for adrenal fatigue?

I'm reading a book about adrenal fatigue, and I almost certainly have it based on the symptoms. Before learning of adrenal fatigue, I started taking a valerian/passionflora/magnesium supplement as well as choline, which have substantially helped my anxiety and muscle stiffness, but which do not do as much for my energy levels. In reading my book on adrenal fatigue, I'm disconcerted to learn there are 6+ supplements recommended for me to take, and specific kinds of each supplement. I don't' feel like popping 50 pills a day (especially when I've had bad side effects with some previous supplements), and I really don't have that money available to spend each month, so I'm wondering, which one or two supplements would definitely help with adrenal fatigue.
