Lactoferrin

What lactoferrin is and where it comes from

Lactoferrin is a protein that binds iron. Your body makes it in tears, saliva and mucus, and it also occurs in milk. The lactoferrin in supplements is almost always taken from cow's milk whey, which is why the label names milk as an allergen. Most products are lactose-free, because lactose is removed when the protein is separated, but the milk protein itself stays. That matters if you react to dairy protein rather than to lactose. As a protein, it belongs with the other protein and amino acid supplements in our range.

Apolactoferrin, native lactoferrin and hydrolysate differ

One lactoferrin molecule can carry two iron atoms. How much iron it already holds is what separates the forms you see on labels.

• Apolactoferrin is stripped of nearly all its iron, so most binding sites are still open.
• Native or holo lactoferrin is left as it occurs in milk, only partly loaded with iron.
• Lactoferrin hydrolysate is broken into fragments and is the least studied of the three.

Two more label details decide what you actually get. First, purity: "250 mg" can mean 250 mg of a powder that is 90 per cent lactoferrin, or 250 mg of the protein itself. Second, processing. Lactoferrin is heat sensitive, so freeze-dried and low-temperature methods are named on better labels. If a product mentions neither purity nor process, you are buying blind.

How we select lactoferrin

We judge these products on form, dose and sensible combinations. We want a stated purity and a clear form name, so you know whether the milligrams on the front are powder or protein. We stock both apolactoferrin and native lactoferrin, and we say which is which. Combinations with vitamin C or colostrum earn their place; vague immune blends carrying a few milligrams of lactoferrin do not. Every product passes our compliance team before it goes live, we test products ourselves, and independent labs spot-check batches. You can read how we select our brands.

Who buys lactoferrin, and what to expect

Most people who look for it are already interested in gut and immune support, or they came across it through iron. Note the difference in how these are described: iron carries approved European claims, for example for normal red blood cell formation and for reducing tiredness. Lactoferrin itself has no approved EU health claim yet, despite a growing research base. So we describe the protein and let you decide, rather than promise an outcome. If iron status is your reason for looking, our range of iron in different forms is the more direct route, and a blood test from your GP tells you more than any label can.

Doses on the UK market usually sit between 100 and 300 mg per capsule, taken once daily. Users commonly run it for a few months and then pause, rather than treating it as a permanent daily habit. Give it two to three weeks of consistent use before you judge anything, and keep expectations proportionate: this is one protein in your routine, not a shortcut. People who like the wider milk-derived approach often also look at Colostrum, which naturally contains lactoferrin alongside other milk proteins, though usually in smaller amounts per serving.
