Frequently asked
Common questions.
Do I need an iron supplement?
Test ferritin first (your iron stores). Most supplementing without testing is wasted money. Iron-deficient women, vegans, and athletes commonly benefit.
How much iron should I take?
Test-driven. Most deficiency-treatment doses are 65-100mg elemental iron daily. Low-dose 18mg for maintenance.
How can I improve iron absorption?
Take with vitamin C. Avoid coffee, tea, and dairy within 1 hour. Take on empty stomach if tolerated.
Why does iron upset my stomach?
Standard ferrous sulfate is harsh. Switch to bisglycinate or liposomal forms, much gentler with same absorption.
