$1.00 a day · 30-day supply
Lactoferrin is an iron-binding glycoprotein found in milk, saliva, and other secretions, where it forms part of the body's innate immune defenses. It is used to support immune function and to modulate iron availability, binding free iron into a form the body can regulate. Lactoferrin plays a role in maintaining gastrointestinal microbial balance and supporting mucosal immunity.

About this supplement
What Is Lactoferrin?
Lactoferrin is a protein of milk. It belongs to the whey fraction, is most concentrated in colostrum, and appears again in tears, saliva and other secretions. The material in this capsule comes from cow's milk, so it is a dairy ingredient. There is 300 mg per serving.
How It Works in the Body
It is a glycoprotein: a long chain of amino acids with sugar chains attached, folded into two lobes. Each lobe closes around a single atom of iron in its ferric form, and it holds that iron only with a carbonate ion clamped in beside it.
The grip is tight and stays tight across a wide range of acidity, the gut included. It follows the general rule for iron in the body: iron is never left loose. It moves from protein to protein — transferrin in blood, ferritin in storage, lactoferrin in secretions.
What It Supports
- Iron binding: Each of the protein's two lobes closes around one ferric iron ion, holding iron in a bound form.
- A milk protein: Lactoferrin is part of the whey fraction of milk and is most concentrated in colostrum.
- Found in secretions: The same protein turns up in tears, saliva and the granules of certain white blood cells.
- Immune function: Lactoferrin is part of the body's innate immune secretions and supports normal immune function.
Who It May Suit
People who are comfortable with dairy and want a single-ingredient capsule rather than a blend. This is a milk protein, so anyone with a milk allergy should not take it, and it does not fit vegan or dairy-free eating. The capsule shell itself is cellulose.
Good To Know
Supplemental lactoferrin is usually the iron-free form, so it arrives with its binding sites empty. Talk with your healthcare provider before use if you have a milk allergy, if you take iron or have a condition that causes iron to build up in the body, or if you are pregnant or nursing.

FAQ
Common questions
What is lactoferrin?
An iron-binding protein found in milk, and in tears, saliva and other secretions. It sits in the whey fraction and is most concentrated in colostrum, the first milk. The lactoferrin in this capsule is isolated from cow's milk, at 300 mg per serving, with nothing else added.
How does it work?
Lactoferrin is folded into two lobes, and each lobe shuts around a single ferric iron ion, held in place with a carbonate ion beside it. The hold is unusually tight and survives acidity that would make many proteins let go, so the iron stays bound through the digestive tract.
What makes this form different?
It is one ingredient and nothing else: 300 mg of bovine lactoferrin per serving in a cellulose capsule, with no colostrum powder, whey concentrate or immune blend around it. Supplemental lactoferrin is usually supplied in the iron-free form, meaning the binding sites arrive empty rather than loaded.
Who is it for?
People who are fine with dairy and want the isolated protein rather than a colostrum or whey blend. Because it is a milk protein, it does not suit vegans, anyone eating dairy-free, or anyone with a milk allergy. The capsule and flow agents are plant-derived.
What should I know before taking it?
This is a milk-derived protein, so a milk allergy rules it out. Talk with your healthcare provider before use if you take iron, if you have a condition that causes iron to build up in the body, or if you are pregnant or nursing, since iron handling matters in each of those cases.
