Focused support for natural immune function
Features a protein naturally present in mucosal barriers
Made with branded Bioferrin® 2000

Overview

Lactoferrin is a specialized protein found at the body's first points of contact with the environment, including colostrum, milk, saliva, and tears. Its strong ability to bind iron has made it a subject of long-standing research on mucosal immunity, communication with immune cells, and iron metabolism.

Doctor Life / 01

Lactoferrin bLF 200 mg

Made for your daily routine.

Bovine lactoferrin is well characterized and widely used in oral research. Digestion can release smaller peptides, including lactoferricin, which are themselves studied for biological activity. This makes its behavior more complex than absorption of an unchanged protein alone.

The formula uses Bioferrin® 2000 from milk whey. Lactoferrin preparations can differ in purity, iron saturation, and protein integrity. Choosing a characterized branded ingredient makes its source and specifications clear.

Lactoferrin bLF 200 mg

What is lactoferrin?

Lactoferrin is an iron-binding protein found in milk, particularly colostrum, and in mucosal secretions. Researchers study its interactions with immune cells, the digestive tract, microorganisms, and iron metabolism.

Lactoferrin bLF 200 mg

What research informs Lactoferrin bLF 200 mg?

Human studies, including trials using 200 mg daily, have examined immune measures and respiratory symptom scores. Iron metabolism is another research area. A 2026 trial found that 200–400 mg of bovine lactoferrin did not replace ferrous sulfate for treating iron-deficiency anemia. Lactoferrin is a bioactive protein, not an alternative form of iron.

How to use

Part of your daily rhythm.

How to use

Adults: take 1–2 capsules daily with a meal. For children, the capsule may be opened and its contents dissolved in a liquid. For infants and children over 1 year of age: dissolve the contents of 1 capsule in lukewarm water, milk, yogurt, or another liquid and mix well. Consume immediately after preparation. Do not add to hot liquids. The capsule contents may also be emptied directly into the mouth.

Important information

Do not exceed the recommended daily serving. Food supplements should not replace a varied diet. A balanced diet and a healthy lifestyle are recommended. Store at room temperature, away from sunlight and out of reach of young children.

Science & sources

Understand the formula.

Lactoferrin is a widely studied bioactive milk protein. Clinical trials examine immune responses, comfort during periods of increased exposure to infection, and iron metabolism. Studies using 200 mg of bovine lactoferrin daily are particularly relevant to this product's one-capsule serving.

These publications concern the studied ingredients or formulas. They do not all evaluate the finished Doctor Life product, and research results do not guarantee individual outcomes.

01Effects of Bovine Lactoferrin on the Maintenance of Respiratory and Systemic Physical Conditions in Healthy Adults-A Randomized, Double-Blind, Placebo-Controlled Trial

Hirotsugu Oda, Shutaro Kubo, Asuka Tada, Takumi Yago, Chihiro Sugita, Hiroki Yoshida, Tatsunori Toida, Miyuki Tanaka, Masahiko Kurokawa

Nutrients (2023), 15(18), 3959. DOI: 10.3390/nu15183959; PMID: 37764743.

In a randomized, double-blind study, healthy adults took 200 mg of bovine lactoferrin daily for 12 weeks. The lactoferrin group showed lower combined severity of respiratory and systemic symptoms, along with changes in plasmacytoid dendritic cell activity. The study examined bovine lactoferrin at a dose relevant to this product.

02Oral lactoferrin reduces systemic inflammation, enhances anti-viral responses and modulates immune cell profiles: a randomised controlled trial in healthy, older adults

Bronwyn S. Berthon, Evan J. Williams, Lily M. Williams, Kurtis F. Budden, Sarah A. Hiles, Nathan W. Bartlett, Lisa G. Wood

British Journal of Nutrition (2026), 135(9), 929-943. DOI: 10.1017/S000711452610631X; PMID: 41634901.

A study in healthy adults over 50 compared 200 mg and 600 mg of lactoferrin daily with placebo over four weeks. Both doses affected selected immune cell profiles, while the higher dose also affected some inflammatory markers. The study examined lactoferrin as an ingredient and its dose-related effects on immune measures.

03Bovine Lactoferrin Compared With Ferrous Sulfate for Treating Iron-Deficiency Anemia in Bangladeshi Women-A Randomized Controlled Trial

Tanvir M. Huda, Sajia Islam, Nazia Binte Ali, Shams E. Tabriz Bhuiyan, Qazi Sadequr Rahman, Rubhana Raqib, Armando Teixeira-Pinto, William Tarnow-Mordi, Shams El Arifeen, Michael J. Dibley

The Journal of Nutrition (2026), 156(8), 101672. DOI: 10.1016/j.tjnut.2026.101672; PMID: 42302886.

A large double-blind trial compared 200 mg and 400 mg of bovine lactoferrin with ferrous sulfate in women with iron-deficiency anemia. Lactoferrin did not match the iron supplement's effect on hemoglobin. This is an important limitation: bovine lactoferrin is a bioactive protein studied in iron metabolism, but should not be presented as a replacement for iron-deficiency treatment.

FAQ / Lactoferrin bLF 200 mg

Good questions. Clear answers.

Talk to us ↗

Is lactoferrin simply iron in a capsule?

No. Lactoferrin is a protein that binds iron; it is not an iron supplement. A 2026 trial in women with iron-deficiency anemia found that 200 or 400 mg did not replace ferrous sulfate treatment. Follow medical advice for a diagnosed iron deficiency.

Has 200 mg of lactoferrin been studied in people?

Yes. Human trials have used 200 mg daily, including a 12-week study in healthy adults published in 2023 and a study in adults over 50 published in 2026. Matching a studied amount does not guarantee a result.

Why use Bioferrin® 2000?

Lactoferrin preparations differ in purity, protein integrity, and iron saturation. Bioferrin® 2000 is a branded milk whey-derived ingredient with specified quality characteristics, supporting consistency between batches.

Is bovine lactoferrin identical to human lactoferrin?

No. They are related proteins with several similar biological properties. Bovine lactoferrin, abbreviated bLF, can be obtained from milk whey and is widely used in oral supplements and research.

Does digestion remove all of lactoferrin's biological activity?

Not necessarily. Digestion breaks down the protein but can also produce smaller peptides, including lactoferricin, that are studied for biological activity. Human trials have examined measurable responses to oral bovine lactoferrin.

Can the capsule be opened for a child who cannot swallow it?

Yes, if a pediatrician or pharmacist has confirmed suitability and the amount. Mix the contents into lukewarm water, milk, yogurt, or another suitable liquid and give immediately. Do not add it to hot liquid.

Is this product dairy-free or vegan?

No. It contains lactoferrin derived from milk whey and a gelatin capsule. It is unsuitable for vegans and for people with a milk protein allergy.
