There are different chemicals that supply the iron, and some are more easily absorbed than others. The best, as far as the quantity and availability of the iron, is listed on the ingredients label as carbonyl iron. The particular brand I use is Sundown Perfect Iron, but other brands are available as well. I got mine on Amazon for very short money.

Happily, carbonyl iron is also supposed to be the best for constipation. When I switched to carbonyl, it helped a lot.

Oh, and the Sundown iron pills are really tiny, if that helps.

My nutritionist recommended Vitron-C as well since the vitamin c makes it easier for your body to absorb the iron. Since I have always been a little anemic my primary doctor has prescribed 325 mg daily of Ferrous Sulfate which is actually a lot cheaper for me even with buying vitamin C since I have insurance for prescriptions and my copay for generics is really low. Did they caution you to not take the iron at the same time as your calcium or multi? I was told to take the iron and vitamin c in the evening and the calcium and the multi in the morning.

I should have added this information as well, so I thought I would emphasize it again, thanks to JfMarrs. You should separate your iron and your calcium by two hours, and taking vitamin C with your iron will help you to absorb it. I take extra vitamin C with my iron. Some brands have the C with the iron, but sometimes it is at too low an amount to help. I don't know anything about the Vitron C, so I'll have to check that out.

Hi! I have been taking all my vitamins from Bariatric Advantage ( I buy mine off of Amazon because they come wayyyy faster). Bariatric Advantage was recommended by my surgeon's office, and it's the only kind I take - all of them are chewables and therefore I know that I'm getting the vitamins in my system. I love the tropical flavor of the iron supplement. Their Calcium chews are also amazing! I do the caramel ones. The multivitamin chews are somewhat nasty but when I take them all at once (beside the calcium) it hides the taste and I just take a sip of water or chew some gum afterward. Problem solved.

I am three years post gastric bypass and started having low iron last October. My surgeon recommended Vitron C. I have also taken liquid iron supplements called Wellesse. Apparently this is a common problem with gastric bypass and about fifteen percent of patients may have iron and other vitamin deficiencies. It is important to keep being checked so you body doesn't not start using bone and muscle mass for nutritional needs. I also use Barilife powdered vitamins since I would have to take eight giant vitamin tablets for my type of surgery. Three scoops a day in juice takes care of my needs and is easier for me to take than tablets.

I did need iron infusions this year via IV. This made me feel better though I did not have major symptoms of anemia.

But I have no regrets. I have lost 360 pounds and now weigh less than I have since fourth grade. I am off all diabetic and blood pressure medicine and have been declared no longer diabetic. My weight actually starts with 1! And I have had the fun of buying several new wardrobes as my weight has dropped. Now saving for excess skin surgery.
