Iron deficiency knows no boundaries - from women (it's estimated that up to 26% of women of childbearing age suffer from iron deficiency) to athletes, seniors and vegetarians - it's a widespread phenomenon.

Other symptoms include weakness, pale complexion, dark circles, brittle hair and nails, shortness of breath and cold hands and feet. Think you're suffering from an iron deficiency?
