I have IDA too. I have found myself to be mostly intolerant to oral iron though (and I have tried the ferrous salts, Gluconate, and the slow release kind too). Slow release didn't cause any noticeable discomfort but it appeared to be not very effective at raising levels in my case.
Ferrobine Syrup I tolerate very well but the dosage is too less.
My Hgb was 8.9 in Nov 20 and after I took iron injections for it, it has risen to 10.8 in Feb 21. The iron injections were really good in terms of tolerance.
