Ask specifically for a ferritin test, because that is the value that tends to fall first.</div></details><details><summary>How much iron should I take, and when?</summary><div class="a">Only supplement if a test shows you are low. Thorne’s form provides 25 mg of elemental iron in one daily capsule; taking it with a vitamin C food and away from coffee or tea improves absorption.</div></details><details><summary>Will it upset my stomach?</summary><div class="a">Conventional iron often does. A <a href="https://ods.od.nih.gov/factsheets/Iron-HealthProfessional/" target="_blank" rel="noopener">chelated form</a> is designed to be gentler, but if you get cramping, take it with a small meal or every other day and ask your doctor.</div></details><details><summary>Who should not take iron?</summary><div class="a">Anyone whose iron is already normal, anyone with a condition that causes iron overload, and children. Iron is a leading cause of accidental poisoning in kids, so keep it locked away, and clear supplements with your doctor if you are pregnant or on medication.</div></details></div><div class="src-list"><h3>Sources</h3><ul><li><a href="https://ods.od.nih.gov/factsheets/Iron-HealthProfessional/" target="_blank" rel="noopener">NIH Office of Dietary Supplements: Iron</a></li><li><a href="https://nutritionsource.hsph.harvard.edu/iron/" target="_blank" rel="noopener">Harvard T.H.
