Suplement
I bought the newer version of the product and it was more expensive, but when I spoke to the sales representative, they told me that the content of the product is the same, and they didn’t change my product

The only Iron supplements that doesn’t upset the stomach

I LOVE my new Iron supplements, amazing, and no stomach upset!
I started taking this after dealing with low iron symptoms, and I’ve tried a few different brands over time—this is one of the better ones I’ve used.What I noticed pretty quickly is that it’s gentle on my stomach. A lot of iron supplements can cause nausea or constipation, and this one didn’t do that for me, which makes it much easier to stay consistent. I take it away from other supplements and protein for better absorption, and over time I’ve noticed improvements in my energy levels.The quality feels very clean, which is why I trust this brand in general. It’s not the cheapest option, but for something like iron, I’d rather go with something that absorbs well and doesn’t cause side effects.Overall, this has been a really solid addition to my routine, especially if you’re trying to correct low iron without upsetting your stomach.

Doesn't work for everyone!
I have been using Thorne Ferrasorb for two months now and while intially it worked great and I felt so much better and the pills were gentle on stomach, with no side effects, the second month didn't work well. I am now getting hurt burns and nasty metallic taste after taking the pills, even with food or after full tummy.

Easier on stomach
I had very low Ferritin and Iron in January. I was feeling horrible (In Perimenopause). I tried 3 different iron pills before I found Thorne. I had horrible stomach issues or constipation with the other iron. I was ready to give up on finding Iron in a pill because honestly having stomach issues every day is another kind of stress on the body. These aren’t perfect on stomach but the best so far. I was taking Vitamin C, Iron and B12 all separate so it’s nice to have it all in one pill. I have also changed my diet to add more iron and vitamin C. I haven’t had my levels checked again, but after 4 months I feel human again, energy back, no more hair loss. I take them every other day and on the Opposite Day take my multivitamin.

Increased my ferritin!!
Not one to typically leave reviews but I am highly impressed by this supplement. I take one in the morning and wait about an hour before eating or drinking anything afterwards. It has raised my ferritin from 40 to 90 in 3 months!! I have not experienced digestion issues from it either. Does have a little bit of an iron test but that’s pretty much unavoidable with any iron supplement. Just ordered my second bottle!
