For immune support and iron regulation, this delivers 250 mg of **Lactoferrin** per capsule — right in the 100–300 mg range used in most clinical studies on immune modulation and gut health. Lactoferrin is an iron-binding glycoprotein naturally found in breast milk and colostrum, with research supporting its role in your body's immune defense and iron absorption.

The evidence for lactoferrin is moderate but growing — RCTs have shown benefits for iron status in pregnant women, reduced duration of common GI infections, and support for beneficial gut bacteria. It works differently from standard iron supplements by enhancing your body's own iron regulation rather than flooding it with elemental iron.

The main caveat is that lactoferrin research is still relatively limited compared to mainstream immune supplements like zinc or vitamin C. Most positive trials are small in scale. If you're specifically looking for immune support with iron-regulating benefits, the dose here is appropriate — but set your expectations around the current evidence base.
