I ran some lab test today; Results, HGB has been dropping for the past 8-9 months. HGB=12.2 ,MCV 77.1, MCH 23.9 MCHC 31.0, TIBC 537.9,Iron 44.4, Transferrin 414.305 ,%SAT 8, B12 369 ,Ferritin 6.32 Folate 5.5, . Should I start with trying to increase Fe in my diet? I have read that I should not take iron supplements without first consulting a Dr. is this true?
