Aside from vitamin C, and adaptogenic herbs (ashwagandha, licorice root, nettle leaf tea or powder, among others), pantothenic acid (vitamin b-5) is extremely important for nourishing your adrenal glands and getting them to normalize.
The best sources of b5 are crimini mushrooms (excellent), steamed cauliflower (very good), steamed broccoli, raw sunflower seeds, tomatoes, strawberries, grapefruit and yogurt.
