The best multivitamin with iron depends on your specific dietary needs and life stage. For reproductive-age women, reputable, third-party tested options like Nature Made Multi for Her or One A Day Women?s are excellent choices, as they provide the daily recommended 18 mg of iron. However, the ideal supplement is one tailored to your specific blood work. I highly recommend getting a quick blood test to check your iron levels before starting, as excess iron can cause stomach upset or health complications. If you are pregnant, a specialised prenatal vitamin with iron would be best.
