Printable Vitamin & Mineral Guide
One-page A4 poster. Green = OK together; amber = timing matters; red = special rules.
✓ OK TOGETHER
No special timetable. Standard B-complex doses can be taken together.
Usually fine together at typical supplement doses.
Fine together. C may improve iron uptake, but an extra C pill is not always needed.
◷ TIMING MATTERS
Consider separate doses when treating iron deficiency.
Avoid swallowing together when taking around 25 mg or more elemental iron.
Follow the antibiotic label. Calcium, magnesium, iron and zinc can reduce absorption.
Separate by at least 4 hours under usual labeling instructions.
! SPECIAL RULES
About 50 mg zinc/day for weeks can lower copper. Changing the time of the pills does not eliminate the risk.
Tell the laboratory. A high-dose supplement may distort results; the pause depends on the test.
Keep vitamin K intake steady. Coordinate changes with your prescriber.
For doses, exceptions and references, see the complete article. The A4 file keeps all three groups on one printable sheet.
On iPhone, Open / Save opens the poster in a new tab: use Share → Save to Files. For printing, keep Portrait selected; the landscape poster is rotated to fill the A4 page. You can also save the print preview as PDF.
For the underlying studies, doses and exceptions, read the full evidence review. This is educational information, not a personal treatment schedule.
