Stay off the adaptogens, you won't be able to clear their byproducts and metabolites, and they'll just set you back further.
What you need is Vitamin C and the pantethine form of B-5, in supplement form, and this is according to the only two doctors who treat adrenal fatigue around the clock -- Dr. James Wilson (who wrote the AF book, buy it!!!), and Dr. Michael Lam. Both brought themselves back from Stage 3 AF.
Hver is going to say that food sources are better and that C supplements are unstable, but they work! Trust me!
