I use the chewable iron from Bariatric Advantage (has 68mg of iron). This formula has a built in Citric acid for better absorption and to help with constipation. I never had any issues, my bowl movements are normal and regular with no constipation, I take two/day. On top of all it tasts really good (lime flavoured) with no after metal taste.
You can order them online for $38 for 90 pills, but if you order a bigger container (270 pills) the price is so reasonable.
Check it out, see if it applies to you
If you have issues with constipation, you may want to introduce fibers to your daily supplements, like Benefiber, you can get it off the shelf from any health store or drug store
