You've been here before. Take iron, feel awful, quit. Repeat. That's not your fault — that's ferrous sulfate. The cheap stuff that sits in your gut unabsorbed, causing havoc.
Root of Nature uses chelated iron bisglycinate. It absorbs through your intestinal wall — not against it. Nothing left behind to irritate your stomach.
Even women who couldn't tolerate any iron supplement are taking this one daily. Zero issues.
