What is lactoferrin?
A plain-English explanation of the molecule — what lactoferrin is, where bovine lactoferrin comes from, and why dose and purity are the things actually worth checking. No hype, and no health claims — just what it is.
The one-sentence version
Lactoferrin is a naturally occurring iron-binding glycoprotein — a protein, found in milk, that holds onto iron. That is the factual description of the molecule itself. Everything below simply unpacks what that means and how to read a label, not what it does for you.
“Glycoprotein,” in normal words
A glycoprotein is just a protein with sugar groups attached to it. Lactoferrin’s particular structure lets it bind iron tightly, which is why it is described as “iron-binding.” When you see that phrase, it is describing the molecule’s chemistry — it is not a statement about health.
Where it comes from — bovine vs human
Lactoferrin occurs naturally in mammalian milk. The lactoferrin used in supplements — including ours — is bovine, meaning it is sourced from cow’s milk. Bovine and human lactoferrin are closely related (homologous) proteins, but not identical; bovine is the form used in the large majority of lactoferrin supplements.
Because it is milk-derived, lactoferrin is suitable for vegetarians but not vegans, and is not suitable for a strict dairy-free diet — even though the capsule shell itself is plant-based.
Lactoferrin is not colostrum
A common mix-up worth clearing up. Colostrum is the first milk produced after birth and contains many different components, of which lactoferrin is only one. Isolated lactoferrin is a single purified protein — it is not colostrum, and not a colostrum extract. If a product’s label says “colostrum,” you are buying something different.
It is not an iron supplement either
Lactoferrin binds iron — but that does not make it a source of supplemental iron. If your goal is to top up iron itself, a lactoferrin supplement is not that product. We point this out because “iron-binding” is easy to misread as “an iron tablet.” It isn’t.
Why dose and purity are the things to check
Because no health claims are authorised for lactoferrin in the UK or EU (more on that in Guide 02), the only things you can meaningfully compare between products are factual:
- ✓How much lactoferrin is actually in a serving, stated in mg.
- ✓Single active or padded — one ingredient, or fillers and a “proprietary blend.”
- ✓Source named — bovine, from cow’s milk, stated plainly.
- ✓Independently tested — a lab confirming identity, purity and contents, with a Certificate of Analysis available.
- ✓Capsule type — ours is a vegetarian HPMC shell.
For reference, Vitality Lactoferrin is 250mg of high-purity bovine lactoferrin per serving (two capsules), as a single active ingredient with no fillers, and every batch is third-party tested at an ISO/IEC 17025-accredited laboratory.
We make no health claims for lactoferrin
Lactoferrin has no authorised UK or EU health claims, so we don’t make any — no immune, gut or disease claims. This guide describes what the molecule is and how to read a label. It is general information, not medical advice, and not a claim about what lactoferrin does. The honest regulatory position is set out in Guide 02 — Dose, purity & honesty.
Common questions
Is lactoferrin vegan?
No. It is bovine — sourced from cow’s milk — so it is suitable for vegetarians but not vegans. The capsule shell itself is plant-based (HPMC).
Is it the same as the lactoferrin in human milk?
They are closely related (homologous) proteins, but not identical. Bovine lactoferrin is the form used in the large majority of supplements.
Is it an iron supplement?
No. It is described as an iron-binding glycoprotein, but it is not intended as a source of supplemental iron.
Is it colostrum?
No. Colostrum contains many components; this is isolated lactoferrin as a single active ingredient — not colostrum, and not a colostrum extract.
How much is in the Vitality product?
250mg of high-purity bovine lactoferrin per 2-capsule serving — a single active ingredient, no fillers, with the amount printed plainly on the label.
250mg. Single active. Every milligram on the label.
High-purity bovine lactoferrin, third-party tested every batch, made in the UK.
