Iron glycinate versus iron supplements

Hi, there are a few studies evaluating the iron glycinate comparing with fumarate. Many of them are observational studies so class two evidence but there is at least a couple of studies with good evidence that they’re better absorbed and the stomach side effect may be a little less so that over all absorption is a little bit better. However, at the end of six months, the results were the same in the levels of iron and hemoglobin. So yes, if your stomach gives you your problem and you have difficulty tolerating definitely worth a try
