Hello. I am a 42 year old female and have struggled with low ferritin levels. At last blood draw, my ferritin was 22 but my total iron was a little high at 189. I have been supplementing with only about 20 mg but now have raised it to 40 mg of iron daily. My zinc is also low at 65. I also am hypothyroid and take 60 mg of armour thyroid daily. I have read that it is very common for hypo patients to also have low blood ferritin levels. I would love to raise them as my hands and feet are always cold- especially when I exercise outdoors. I believe that I am otherwise healthy in a healthy weight and blood pressure- I just experience ongoing hair shedding. Should I worry about any internal bleeding issues?
