Larger doses of vitamin C are not toxic and can be safely taken. Dr. Donsbach strongly recommends pantothenic acid, vitamin B5, a nutrient critical to adrenal function. Without an adequate supply of pantothenic acid, the adrenals cannot product cortisone. He suggests daily dosage ranging from 100 mgs to 3 grams daily, because individual requirements can vary so greatly. Adelle Davis advocates pantothenic acid 100 mgs along with vitamin C 500 mgs every two to three hours in acute situations as part of an anti-stress program.
Recent studies show quercetin, a bioflavonoid, reduces inflammation.
Dr. Donsbach advises a hypoglycemic diet for asthmatics because hypoglycemia itself is associated with malfunctioning adrenals. He recommends eliminating refined carbohydrates and sugars, coffee, tea, smoking and alcohol. Eating complex carbohydrates, proteins, fruits and vegetables is desirable. Vitamin A is another important vitamin for asthmatics. It supports lung function and protects against infection.
