How much iron do I need in my multivitamin?

Each person will need a different amount of iron based on several different factors, including sex, gender, and health history.
Always consult with your healthcare team when determining the appropriate amount your body needs.

Below are general guidelines for needs by surgery provided by the ASMBS:

  • Non-Weight Loss Surgery – 18mg per day
  • Restrictive, LapBand or Sleeve Surgery – 18mg per day
  • Malabsorpative, Gastric Bypass, RNY – 45mg per day
  • Severe Malabsorpative, Duodenal Switch/Sadi Procedures – 60mg per day

*Please note, menstruating women typically need more iron, around 36-45 mgs daily regardless of surgery, but again this can fluctuate based on health history.
Please check with your doctor or dietitian to see what your health history dictates you need. You will also have frequent labs pulled to check on your supplement levels for the first 2 years post-surgery.
