I just want to note, as inquiring minds want to know, that Vitamin D is a "steroid," Cholesterol is a "steriod," etc. The treatment is with hydrocortisone, which is bioidentical to our natural hormone cortisol. The other "steroids" of which they speak are much more familiar to medical doctors, e.g. prednisone. However, Dr. Marik's treatment is with hydrocortisone which (t least emergency room) doctors will have to become familiar with.
