Review: Great little pills - My midwife recommended these because of my low iron levels. They work great! And even better they don’t cause conspation
Review: Iron that is easy on the stomach - This is one of the very few iron supplements I have found to be easy on my stomach. The pill size is also not large so it is easy to swallow.

Again everyone should talk to their doctor but I would recommend to anyone with sensitive stomachs who have a hard time digesting.

## Questions & Answers

**Q: Is it no longer vegetarian? They seem to have removed that from the label.**
A: This is because Ferrasorb now contains leucine. Leucine is an amino acid that is used instead of other flowing agents that can reduce nutrient absorption. The leucine Thorne uses is derived from duck feathers. The ducks that the feathers come from are not killed for their feathers; rather, their feathers are collected off the ground after the feathers fall off naturally.

**Q: What is the size of these pills pls? i have a problem with very large pills. can someone post a picture with some reference like a penny?  many thanks**
A: I can't post a pic, but I would call these fairly small for a capsule.  They are certainly not "very large pills".  I take another iron capsule and a vitamin C capsule, and they are much larger.

**Q: Has this product raised anyone's serum iron levels? Not just ferritin.**
A: Yes,  my hemoglobin was at 8mg/l and started taking this 2 to 3 times per day.  My check-up yesterday I was back at 14.5mg/l and ALL other levels were normal.  Worked perfect for me.

**Q: Is this the old Picolinate or the new Bisglycinate formula ?**
A: It is Ferrous Bisglycinate Chelate.

### ⭐⭐⭐⭐⭐ Great little pills
*by A***Y on December 31, 2025*

### ⭐⭐⭐⭐⭐ Iron that is easy on the stomach
*by L***A on November 2, 2025*

This is one of the very few iron supplements I have found to be easy on my stomach. The pill size is also not large so it is easy to swallow. I am anemic but it has helped and been effective raise my ferritin level.

### ⭐⭐⭐⭐⭐ Felt an Energy Boost After Just One Dose
*by T***E on December 11, 2025*

I took this iron supplement once and actually felt more energized the same day. I’m usually sensitive to iron, but this one didn’t upset my stomach or cause any side effects. The capsule is easy to take and feels very clean and high quality, which is what I expect from Thorne. Of course results vary, but if you’re low in iron or just looking for a well-absorbed iron complex, this one seems to work quickly. I’ll continue using it to see the longer-term benefits, but my first impression was very positive.
