## 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.

### ⭐⭐⭐⭐⭐ Small sized pill!
*by C***7 on February 18, 2026*

Small sized pill and hasn’t made me constipated (like most iron supplements) so far I think it’s good value for the money and I love the quality of Thorne products

### ⭐⭐⭐⭐⭐ Incredible
*by A***S on February 14, 2026*

I had all the usual symptoms: dull skin, wickedly painful heavy periods, depressing thoughts, low ferritin levels etc. After six days of using, the color in my face and hands came back. All of the symptoms I would typically get a week before my period never showed up, my flow and cramping was back to normal. It’s been three months since I started taking this and my hair is starting to thicken up again. My ferritin levels are also up and I haven’t had any issues with cold feet/hands. I started with two pills a day for the first month and switched to just one pill a day. I usually take it with a shot of orange juice or with a mandarin two hours before I eat anything else (or two hours after I eat), that includes coffee. Especially coffee. The pill obviously has a metallic taste so it’s best to swallow it immediately and not let it sit on your tongue. Sometimes I’ll burp and taste metal but it’s fine and doesn’t last long. It does make my poop black though, and smell weird, it frightened me at first but my doctor told me that’s normal. I’m going to keep purchasing this until my doctor tells me I can stop. HIGHLY recommend.
