Ferrous gluconate is: kinder on the gut than the sulfate form. Plus, enteric coated is better for you probably. Will work better for you It's common for the ferrous sultate to be hard on many people's guts. So, choose a kinder version of iron. Depends what kind of meal too may make a difference. A big meal helps coat the tablet from irritating you.Best to not take calcium products at the same time.

Yes: If your baby is breast fed i recommend starting polyvisol with iron, 1 dropper per day, for the entire first year of life starting at 1 week. This covers the needs of vitamin d and iron for the breast fed baby. If your baby is formula fed on a fully iron-supplemented formula, additional iron is usually not required.

Iron: Usually after menopause the persons need for iron drops drastically because the menstrual periods have stopped. Blood loss requires lots of iron to manufacture new red blood cells. After menopause it is advisable not to take iron as too much iron can cause illness in the body e.g. Iron buildup in the liver called hemochromatosis.

Decrease absorption: In low dose, nothing probably will happen. Calcium and iron are taken together in a multivitamin all the time. At higher dose, you might get GI upset. Regarding efficacy, you get less iron absorption if taken with calcium. It is recommended to take iron 2 hr before or 4 hr after calcium supplementation.

Yes: But also ask your doctor. In general, women get a little anemic in pregnancy and this can be normal. We want to improve or avoid the severity of the anemia with supplements. Most prenatal vitamins have a little iron, but you may need an additional supplement if recommended by your provider.
