Is Iron (oral supplements) Safe with Chlorophyll?
Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Take iron supplements separately from chlorophyll by at least 2 hours. Monitor iron status (ferritin, hemoglobin) in patients supplementing both long-term.
Why this interaction occurs
Chlorophyll is structurally a magnesium-centered porphyrin. High-dose chlorophyll supplementation may compete with iron at intestinal absorption transporters (DMT-1) or alter the luminal redox environment, potentially modestly reducing non-heme iron uptake.
Evidence
Evidence level: limited.
Reported safety data
The FDA’s adverse event reporting system (FAERS) has received 291 reports mentioning Chlorophyll. This reflects reported cases involving the medication in general — not confirmed causation, and not specific to the Chlorophyll + supplement combination on this page.
FAERS reports are voluntary and cannot prove that a drug caused an event. Do not use report counts to assess the safety of this specific drug-supplement pair.
