Full and frequent blood tests continually measured low ferritin, but since hematocrit and hemoglobin (and all other) levels were within range, three separate primary physicians and my psychiatrist all indicated there was no problem. I took it upon myself (after ‘internet research’) to gradually get off all the meds prescribed over the course of three years (klonopin, alprazolam, gabapentin, mirtazapine, sertraline, and others) and start supplementation with two basic minerals obtained from WalMart. I felt wonderful almost immediately, and ever since.
