Most people are not even aware of adrenal fatigue stage 1. No nutrients are needed here. Some are alerted when they hit stage 2, where recovery is very slow without good nutrients. When you arrive stage 3, it is unlikely to have significant recovery without a proper nutrient program because the body is quite weak and needs help beyond what rest can do.In fact, the body will get worse as natural progression takes over.

I cannot tell you which is more important. A good recovery program needs both.
