Dosage & Bioavailability
How the active doses and forms in Iron compare to the research.
•Calcium (as Dibasic Calcium Phosphate) — 13 mg per serving; studies use 800-1,000 mg/day.
•Iron (as Ferrous Sulfate) — 65 mg per serving is over the 45 mg/day upper limit (IOM (NIH ODS)). Above this limit iron often causes stomach upset and constipation, and it can build up in people with haemochromatosis; keep iron supplements away from children.
•Iron (as Ferrous Sulfate) — ferrous sulfate is among the preferred forms of iron in Suppie's ingredient library.
