HelloPharmacist Scorecard of Laktoferrin by Allergy Research Group

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: lactoferrin, a naturally occurring protein found in milk and other body fluids. The capsule also holds several inactive ingredients — hydroxypropyl methylcellulose, microcrystalline cellulose, rice hull concentrate, gum arabic, and sunflower oil — which serve as fillers and capsule material.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Lactoferrin's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: immune peptide from colostrum.
  • We looked for evidence on: Respiratory tract infections, Helicobacter pylori, Iron deficiency anemia, Acne, Gut barrier function, Antimicrobial activity — and 1 related terms.
  • The closest evidence on file: Lactoferrin is rated "Insufficient Reliable Evidence To Rate" for Acne (Natural Medicines).
  • Also on file: Lactoferrin is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections, Helicobacter pylori, Iron deficiency anemia.

The evidence for lactoferrin is mixed and depends on the condition. For sepsis and pregnancy-related iron deficiency, the data suggests it's possibly effective.

However, for fetal and premature infant mortality and for necrotizing enterocolitis (a serious intestinal condition in newborns), the evidence points to it being likely ineffective. Talk with your doctor about what the research actually supports for your specific situation.

The evidence, ingredient by ingredient Lactoferrin

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Lactoferrin is generally well tolerated at typical doses taken by mouth, though long-term safety data are limited. The most common side effects are gastrointestinal — diarrhea, constipation, and nausea — and they're generally less frequent than with other iron sources.

At higher doses around 7.2 grams daily, constipation, diarrhea, anorexia, fatigue, and chills become more likely. In pregnancy, some studies have looked at it, but safety isn't fully established — use only under medical supervision.

While lactoferrin occurs naturally in breast milk, the safety of taking supplements while breastfeeding hasn't been well studied.

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the ingredients we could check. That said, always run your full medication list through the search tool on this page before you start, and let your doctor or pharmacist know you're taking it.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.

Lactoferrin may be worth considering if your doctor thinks you could benefit for sepsis or pregnancy-related iron deficiency, but the evidence for other uses is weak or absent. If you're pregnant, breastfeeding, or taking higher doses, talk it over with your own doctor or pharmacist first to make sure it's the right choice for you.
