What is a good Iron Saturation level?

BioForge works to an optimal range rather than the lab's reference flag. For Iron Saturation that is 25–40, measured in % — iron / TIBC. A result inside the lab's normal range can still sit outside the range where most people feel and function well.

Iron Saturation

Measured in % — iron / TIBC

How full your iron transport system is. Distinguishes true iron overload from inflammation.

What the numbers mean

These are the ranges BioForge works to. They are not the same as a lab's reference range, which is built from the general population rather than from people who feel well.

Low

<20 · Iron deficient

Optimal

25–40

High

>45 · Screen hemochromatosis

What moves Iron Saturation

Follows iron intake, absorption, blood loss, and genetics. Fasting is required — a recent iron supplement or iron-rich meal will inflate the result.
