For Iron Deficiency Anemia "I have only been taking ferrous sulfate for 3 weeks but have found the results beneficial. My anemia was affecting my school work and social life as I had no energy to walk and it was really challenging me. Now, I can do normal things and don't get as tired - I believe they are working very well. But, I seem to have got the short straw with the side effects. I now suffer from great constipation. I am also nauseous most days and my appetite has been lost. So, even though I have more energy etc., I am still not myself as I am always feeling sick or having bowel troubles."

For Iron Deficiency Anemia "I've been taking this for three months now. I no longer feel weak in my chest, and I feel I'm getting enough oxygen. Which is great, but my digestive system is so off, and I have regular nausea, stomach ache, and mild constipation. It's making me miserable, as there's nothing worse than nausea."

For Iron Deficiency Anemia "I have been taking this for a week now. My doctor prescribed stool softeners to take with it as well, so I'm not having any problems with the constipation. My hemoglobin is at a 9, and my ferritin level is at a 7. The very first day I took it, I got so sick (nausea, stomach pains, light-headed, and sweating). I have to take it twice a day, and the side effects are less apparent than before. I hope this works."

For Iron Deficiency Anemia "I've only been taking this for about 3 days, and it's been a 3-day pure gastrointestinal nightmare. Stomach ache, bloating, nausea, and the gas! The gas is out of control, and I'm surprised my family still wants to be around me. I am definitely gonna switch to a non-sulfate version."

For Iron Deficiency Anemia "I've been taking ferrous sulfate for 2 weeks now, and I do notice I have more energy. I still get pretty tired early in the night, but when I wake up, I am no longer exhausted. I suffer from GI issues that can easily be triggered if the wrong thing goes into my stomach. I was very skeptical about iron pills, but my doctor told me to take the pills with breakfast. I feel this has helped me not suffer terrible GI issues. If I eat dinner at 6/7 pm and breakfast at 9 am with no lunch or snacks in between, I have noticed that I get really nauseous about an hour after dinner. Although, if I eat more frequently throughout the day, I am completely fine. There have been a couple of days where I didn't pass a bowel movement, but I did not feel like I had to. Typically, it's normal for me to go once a day. I feel I will sometimes experience very mild constipation on this pill. I take a probiotic every single day with the pill to make sure I am as regular as possible."

For Iron Deficiency Anemia "Needed for low iron levels. Reduced my period bleeding, extreme bloating, and some nausea. Even tried taking it with a meal and lots of citrus for vitamin C. Makes stool darker and smellier, I eat lots of vegetables for my normal diet, so no constipation was experienced. Stopped after around a week."
