Hello Allie, I am Kathy - a nutritionist- and I may be able to help you with this Nausea is a common side-effect with iron supplements. There are other iron supplements that are gentler on the stomach and you may want to discuss this with your doctor. I am assuming you are on iron because your iron is low. You can increase your iron naturally by eating high iron foods such as raisens, spinach, molasses and, if you eat meat, red meat is high in iron. Eating a source of high vitamin C along with your iron will increase the amount of iron you absorb, so fruit, vegetables are naturally high in C as is vitamin C enriched juices. Iron should always be taken with food. From what it sounds like, you are not eating with it. Try taking it in the am with food (but not dairy or high fiber foods) and include a source of vitamin c with your iron supplement. Food does decrease absorption, but if the iron is making you nauseous, eat and/or ask to be switched to a gentler form of iron. In summary, take iron in am with food low in fiber and a source of vitamin c. Check with your doctor about these problems and see if there is a gentler form of iron you can take. Increase your iron in your blood naturally by including high iron foods. High iron foods should be combined with a source of vitamin C. Have a Great Day!
