Overview

["THORNE Advanced Iron Complex is a 60 capsule supplement built around elemental iron combined with folate and B and C vitamins. The maker markets it as a complete blood support formula meant to work with the body's absorption process rather than shipping iron in isolation.", 'The chelated iron form is paired with cofactors the body uses alongside iron, which is the reasoning behind bundling folate and vitamin C into the same capsule. The product is labeled gluten, dairy and soy free.', "This sits as a step up in complexity from THORNE's plain iron bisglycinate capsule, aimed at shoppers who specifically want the added folate and vitamin C and B rather than a single-ingredient iron product."]
