What customers say
Customers are highly satisfied with Thorne Ferrasorb, praising its combination of Vitamin C, B6, B12, and Folate (B9) which optimizes iron absorption and supports blood-building. Many users report significant improvements in energy levels, alertness, and overall well-being. The supplement is noted for being gentle on the stomach, not causing constipation or digestive issues common with other iron supplements. The small capsule size and neutral taste make it easy to take. Several customers mentioned that it effectively raised their ferritin levels and helped manage anemia. The high-quality ingredients and reliable brand reputation of Thorne are frequently highlighted. Users appreciate the effective formulation that ensures good iron absorption without side effects.

Thorne Ferrasorb is an excellent iron supplement that combines iron bisglycinate with essential cofactors like vitamin C, B12, and folate for optimal absorption. It’s gentle on the stomach and helps restore energy levels without causing constipation. Highly recommended for those with iron deficiency or fatigue.

The quality of these vitamins is impressive. They are well-made, easy to take, and don’t have an unpleasant taste or aftertaste, which makes daily use simple. The ingredients list is clear and straightforward, and it feels reassuring to know that the vitamins are produced with good standards in mind. Over time, I’ve noticed a consistent level of freshness and effectiveness, which shows attention to quality and proper formulation. Overall, these vitamins offer good value and seem reliable for supporting everyday nutritional needs.

I’m taking Ferrasorb to raise my iron levels. So far, I haven’t noticed a big difference yet, but I think it may take more time. On the positive side, I haven’t experienced any side effects, and there’s no unpleasant taste, which makes it easy to take. Overall, it seems to be good quality.

Just eat more red meat
Verified purchase
I've been supplementing with iron for years and while I think this is one of the better ones, but I can't say I feel much better after months of taking it. I think all iron deficient people should seriously consider just eating more red meat and especially avoiding plant foods which block iron absorption.

Premium-quality iron with a highly bioavailable chelated form, paired with methylated B vitamins for optimal absorption and red blood cell support. Clean, well-formulated, and exactly what I expect from Thorne.
