I am on adrenal support though not as much as it used to be in the beginning of AF treatment (stage 3b). I do not take lots of vitamins anymore. I am taking multi-vitamins, chinese herbs (he shou wu, jin gui shen qi wa), and taking acupuncture.
Multivitamins are generally synthetic and contain very unstable vitamin C (ascorbic acid), which is the main nutrient required by the adrenals. Natural sources of vitamin C are better.
Adaptogens will also help with the adrenals. My favorites are Chinese licorice root, jiaogulan (Gynostemma) and schisandra berry.
