Our assessment
The evidence shows that iron supplementation can be effective for correcting iron deficiency, but the data for Thorne Research Iron Citrate specifically is limited.

For iron deficiency, the RDA for adults is 8 mg for men and 18 mg for women [NIH ODS].
How it works
Iron is a critical component of hemoglobin, which carries oxygen in your blood. It also supports energy metabolism and immune function [NIH ODS]. Iron citrate is a form of iron that may be better tolerated by some individuals compared to other forms, though specific comparative data for this product is not provided.
Safety profile
FDA received 5,516 adverse event reports for iron supplements. Side effects include constipation (1,450 reports), nausea (980 reports), and stomach pain (720 reports) [FDA data]. Taking iron with food can reduce stomach upset but also decreases absorption. Data not available for Thorne Research Iron Citrate specific side effects.
Our recommendation
We recommend getting your iron levels tested before starting supplementation. If you have iron deficiency, start with the lowest effective dose. Take iron on an empty stomach with vitamin C for best absorption, but with food if GI upset occurs [NIH ODS]. Consult your healthcare provider for proper dosing and monitoring.
