I have other deficiencies as well as iron so my symptoms may be over lapping-
I went to the Dr. for fatigue and found out I have iron deficiency and Vit D deficiency (which may also mean a deficiency in calcium since Vit D is required for absorption of calcium).
So far the symptoms that I had before taking iron that are being helped by iron are -
insomnia, dry peeling lips, dry skin, dry peeling feet, fatigue. Its only been a month and a half and supposedly it takes about three months to see the full benefits of iron supplementation.
I should add that I have been taking vitamin D as well, so it could be having some effect. I think its mostly the iron that is helping because I really noticed my lips healing when I took full doses of iron, and my lips get more dry when I miss a dose.
