Dose, purity & honesty

An honest framework for judging a lactoferrin supplement. Because no health claims are authorised for lactoferrin in the UK or EU, marketing promises tell you nothing, so this guide focuses on the five factual things that actually differ between products: dose in milligrams, purity, whether it is a single active or a padded blend, the named source, and whether an independent laboratory has verified what is in the capsule.

Our position

Why we make no health claims

Lactoferrin has no authorised health claims in the United Kingdom or the European Union. No claim about immunity, gut health, iron status or anything else has been approved by the regulator for use on a lactoferrin product. So we make none. Any brand that implies lactoferrin will do something specific for your health is going beyond what the rules permit.

That sounds like a limitation, but it is clarifying. If nobody can legally promise an outcome, then the marketing copy on every lactoferrin tub is worth roughly the same: nothing. What is left are the factual, checkable attributes of the product itself: how much lactoferrin you get, how pure it is, what else is in the capsule, where it comes from, and whether anyone independent has confirmed the label is true.

This page is our argument that those facts are the only honest basis for choosing. We would rather win on a verifiable 250mg single-active spec than on a health promise we are not allowed to make.

If no one can legally promise an outcome, the only honest way to compete is on dose, purity and proof.
The label

How to read a lactoferrin label

Turn the tub around and ignore the front. Everything that matters is in the supplement-facts panel and the ingredients line. Four things tell you almost everything about quality:

Dose in mg
Stated per serving. Look for a clear milligram figure for lactoferrin itself, not a combined blend weight. If the number is missing or buried, that is a choice.
Single active vs blend
One ingredient, or many. A single-active capsule is just lactoferrin. A blend splits the headline weight across several cheaper ingredients, so the lactoferrin share can be small.
Source named
Bovine, from cow's milk. An honest label says where the lactoferrin comes from. Vagueness about source usually hides something worth weighing up.
Independently tested
Verified, not just claimed. The strongest signal is a third-party lab confirming identity and purity, with a Certificate of Analysis you can request.
The number

Dose: the figure that actually matters

Milligrams are the one specification you can compare like-for-like across every brand. A lower price per tub is meaningless if the serving is half the size, and high strength on the front means nothing without a number behind it. When you compare lactoferrin products, normalise everything to milligrams of lactoferrin per day, then look at cost per that.

  • Find the mg figure for lactoferrin specifically, per serving, in the facts panel.
  • Check the serving size — is that dose one capsule or several?
  • Work out cost per mg — tub price divided by total mg across all servings.
  • Beware combined blend figures — a big number next to a blend is shared across other ingredients.
  • For reference — Vitality Lactoferrin is 250mg per two-capsule serving, stated plainly.
Quality

Purity & independent testing

Purity is what the milligram figure cannot tell you. A 250mg serving of a low-purity, poorly handled raw material is not the same product as 250mg of a high-purity one, even though the label number is identical. This is why independent testing matters: it is the only way to confirm that what is named on the label is what is actually in the capsule, and that nothing unwanted came along with it.

We batch-test at an ISO/IEC 17025-accredited laboratory, the international standard for testing competence, and a Certificate of Analysis is available on request. Good testing confirms the identity of the protein, its purity, microbiological safety, and that heavy metals sit within safe limits. A brand that tests and will show you the paperwork is making a very different promise from one that simply prints a number and hopes.

A milligram figure tells you the quantity. Independent testing tells you the quality.
Watch for

Blends, fillers & padding

Most tricks used to make a weak lactoferrin product look strong fall into four categories. None is illegal; all are worth spotting.

Proprietary blends
Hidden ratios. A blend lists a combined weight without saying how much of each ingredient it contains, so the lactoferrin share can be tiny while the headline number looks big.
Bulking agents
Cheap fillers. Rice flour, maltodextrin and magnesium stearate add nothing but volume. A single-active capsule does not need them.
Complex naming
Marketing, not chemistry. Calling a product a lactoferrin complex lets a brand imply more while delivering less actual lactoferrin per capsule.
Underdosing
A sprinkle for the label. Just enough lactoferrin to justify naming it, with the rest made of cheaper ingredients. The mg figure gives this away.
Transparency

Bovine sourcing, stated plainly

The lactoferrin in supplements, including ours, is bovine, isolated from cow's milk. It is closely related to, but not identical to, the lactoferrin in human milk. We think the honest thing is to say all of this on the label rather than leaving a shopper to assume. It also has real practical consequences for who the product suits.

  • Bovine — sourced from cow's milk, like the large majority of lactoferrin supplements.
  • Suitable for vegetarians but not vegans, because it is milk-derived.
  • Not dairy-free — being a milk protein, unsuitable for a strict dairy-free diet.
  • Capsule is separate — our shell is plant-based HPMC; the lactoferrin inside is bovine.
  • Not colostrum, not an iron tablet — isolated lactoferrin, a single purified protein.

Eight red flags on a label

A fast checklist for the next lactoferrin product you pick up. Any one is a reason to look closer; several together, a reason to walk away.

  • No milligram figure for lactoferrin, or only a combined blend number.
  • Proprietary blend or complex with undisclosed ratios.
  • A long filler list crowding out the active.
  • Health claims about immunity, gut or iron — none are authorised.
  • No named source — silence on bovine vs other origin.
  • No testing mentioned, or tested with no lab, standard or certificate.
  • Colostrum used interchangeably with lactoferrin — not the same thing.
  • Vague country of manufacture — no country named.
You should be able to verify every claim on a label. If you can't, treat it as marketing, not fact.

Common questions

Honesty & labelling FAQ

Because no health claims for lactoferrin are authorised in the UK or EU, we are not permitted to state what it does, and we will not imply it. This page is about how to judge a product factually.
Normalise both to milligrams of lactoferrin per day, then divide the tub price by the total milligrams to get cost per mg. Check single active vs blend, named source, and independent testing.
It lists a combined weight for several ingredients without disclosing how much of each, so the lactoferrin share can be much smaller than the headline number suggests.
It is the international standard for the competence of testing laboratories. Batch testing confirms identity and purity of the protein, microbiological safety, and that heavy metals are within safe limits.
Not necessarily. Milligrams tell you quantity, not quality. Compare both dose and testing.
Yes. A Certificate of Analysis for our lactoferrin is available on request.
It suits vegetarians but not vegans, as it is from cow's milk, and not a strict dairy-free diet. The capsule shell is plant-based HPMC, but the lactoferrin is a milk protein.
A clear milligram dose of a single active, a named bovine source, and independent batch testing with a Certificate of Analysis available.

250mg. Single active. Every milligram on the label.
