Thorne Research Iron Picolinate

Brand: Thorne Research · Form: CAPSULE [E0159]

Our assessment

The evidence shows that Thorne Research Iron Picolinate is a targeted supplement for addressing iron deficiency. Iron is essential for making hemoglobin, a protein in red blood cells that carries oxygen to your tissues [NIH ODS]. Our assessment is that this product can be effective, but it is critical to use it only after confirming a deficiency, as excess iron can be harmful.

How it works

This supplement provides iron in the form of ferrous picolinate, a chelated form designed to enhance absorption and reduce gastrointestinal side effects often associated with other iron supplements [NIH ODS]. Once absorbed, the iron is used to support oxygen transport, energy production, and immune function [NIH ODS]. Think of it as a key building block for your body’s oxygen delivery system.

Safety profile

Data not available for specific adverse event reports for this product from the provided FDA data. However, iron supplements in general can cause side effects. Common issues include constipation, nausea, and stomach upset, especially at higher doses [NIH ODS]. Taking iron with food can reduce these effects, but it may also decrease absorption [NIH ODS]. Keep this supplement out of reach of children, as accidental overdose can be fatal [NIH ODS].

Our recommendation

Our recommendation is to only use Thorne Research Iron Picolinate if you have a confirmed iron deficiency, as determined by a blood test. The standard RDA for iron is 18 mg for most adult women and 8 mg for men [NIH ODS]. Start with the lowest effective dose and take it on an empty stomach with a source of vitamin C, like orange juice, to maximize absorption [NIH ODS]. Always consult your healthcare provider before starting supplementation [NIH ODS].
