Public timing reference
Mineral timing conflicts worth separating.
Use this as a quick stack audit for the most common mineral timing problems: magnesium near affected antibiotics, calcium near iron, and chronic mineral patterns that deserve a closer look.
Timing window
The mineral spacing rule at a glance
Magnesium + fluoroquinolone antibiotics
Chelation can reduce antibiotic absorption when taken together.
Magnesium at least 2 hours before or 4-6 hours after the antibiotic.
PMID 24806820Calcium + iron
Calcium can reduce non-heme iron absorption in the same meal window.
Use a clean iron slot. Separate calcium by at least 2 hours.
PMID 1984334Iron + coffee or tea
Polyphenols can reduce non-heme iron absorption.
Keep coffee and tea away from intentional iron dosing.
Review evidenceZinc + copper
Long-term high zinc intake can shift copper balance.
Avoid chronic high-dose zinc unless copper status and dose are monitored.
NIH ODSHow to use this without overfitting
- Keep intentional iron away from calcium-heavy meals and mineral multis.
- Keep magnesium, calcium, zinc, and antacids away from affected antibiotics.
- Do not stop prescribed medication or clinician-directed iron without professional guidance.
- When a timing rule is unclear, ask a pharmacist to check the exact product and medication.
