The full guide
What this product is

The bottle contains 60 capsules, offering a 60-serving supply when following the labeled dose.

Who this product is for
This product is well-suited for people who need iron supplementation and prioritize gastrointestinal (GI) tolerance. It is particularly relevant for those who require gluten-free products and value NSF Certified for Sport status. It may also appeal to individuals who have experienced sensitivity to ferrous sulfate or other iron forms and are seeking a gentler alternative.
Gluten safety and certifications
The product is labeled gluten-free and carries NSF Certified for Sport. While these signals support gluten safety, the sources do not document an explicit third-party gluten certification beyond the gluten-free label, and cross-contact details are not disclosed. Overall, the labeling and certification together point toward a product that is likely safe for individuals with celiac disease or gluten sensitivity, but exact facility-level information is not provided.
Taste, texture, and daily use
Capsules are described as small and easy to swallow, with tasteless capsules and minimal aftertaste. Many users report gentle digestion and a lack of constipation commonly associated with some iron forms. The labeled dose is 25 mg elemental iron per capsule, suitable for daily use as directed on the bottle.
Value, comparison, and what to expect
Priced around $14.40 for 60 capsules, the product is positioned as mid-priced within the iron-supplement category. At roughly $0.24 per serving, it sits between budget options and premium formulations. Compared with cheaper ferrous sulfate products, THORNE emphasizes GI tolerance and gluten-free status, with a differentiator of the iron bisglycinate form and NSF certification.
