Overview

A broader lactoferrin formula. Lactoferrin bLF Forte centers on bovine lactoferrin, a bioactive protein naturally present in milk and colostrum. Known for its ability to bind iron, lactoferrin is extensively studied in relation to mucosal immunity and the gastrointestinal environment.

Doctor Life / 01

Lactoferrin bLF Forte

Made for your daily routine.

We use Bioferrin® 2000, a branded lactoferrin ingredient with a declared purity above 95%. Lactoferrin ingredients can differ in purity, iron saturation, and protein integrity. Identifying the source helps describe what the formula contains beyond its weight alone.

The formula also contains colostrum, the first milk produced after birth, naturally rich in proteins and immunoglobulins. FloraProtect® adds four types of prebiotic fiber, combining milk-derived proteins with ingredients used by the gut microbiota.

Lactoferrin bLF Forte

Why combine lactoferrin, colostrum, and prebiotics?

Lactoferrin binds iron and occurs naturally in mucosal secretions. Colostrum provides a broader mixture of milk-derived proteins, while prebiotic fibers can be fermented by gut microorganisms. The formula combines these different ingredient groups in one product.

Lactoferrin bLF Forte

What does the research say about Lactoferrin bLF Forte?

Clinical studies have examined bovine lactoferrin at 100 and 200 mg daily. A 12-week adult trial using 200 mg reported lower combined respiratory and general symptom scores than placebo. A study in children using 100 mg examined absences associated with vomiting, and research in adults over 50 assessed selected immune-cell profiles. These are ingredient studies with specific populations and outcomes, not proof that this finished formula prevents illness.

How to use

Part of your daily rhythm.

How to use

Children from 4 months of age: 1 sachet daily. Adults: 2 sachets daily. Mix the contents into lukewarm liquid or food, stir thoroughly, and use immediately after preparation. The powder may also be taken directly from the sachet.

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.

These studies used 100 mg or 200 mg of bovine lactoferrin daily, corresponding to the amounts in the children’s and adults’ servings. They examined immune-related and gastrointestinal outcomes in specific populations. The studies did not test the complete formula, and findings in preschool children do not establish effects in infants.

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 trial, 145 healthy adults included in the analysis took 200 mg of bovine lactoferrin daily or a placebo for 12 weeks. Overall severity of assessed respiratory and systemic symptoms was lower in the lactoferrin group, and researchers observed changes in plasmacytoid dendritic cell activity. The lactoferrin amount matches the adult daily serving, but the finished formula was not tested.

02The Preventive Effect of Lactoferrin-Containing Yogurt on Gastroenteritis in Nursery School Children—Intervention Study for 15 Weeks

Teruomi Tsukahara, Anri Fujimori, Yuka Misawa, Hirotsugu Oda, Koji Yamauchi, Fumiaki Abe, Tetsuo Nomiyama

International Journal of Environmental Research and Public Health (2020), 17(7), 2534. DOI: 10.3390/ijerph17072534; PMID: 32272777.

A prospective study randomized 1,296 preschool children. The intervention group received yogurt with 100 mg of bovine lactoferrin daily for approximately 15 weeks. In the final analysis, children who regularly consumed lactoferrin had fewer absences related to vomiting. The amount matches one sachet of Lactoferrin bLF Forte, but the study used yogurt and did not include infants.

03Oral 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 randomized study in 103 healthy adults over 50 compared 200 mg and 600 mg of lactoferrin daily with placebo for four weeks. The 200 mg dose affected selected immune cell profiles, and both doses modified immune cell responses. The lower amount matches the adult serving, although this finished formula was not tested.

FAQ / Lactoferrin bLF Forte

Good questions. Clear answers.

Talk to us ↗

What is Bioferrin® 2000?

Bioferrin® 2000 is a branded bovine lactoferrin ingredient derived from milk. The label declares purity above 95%. Purity helps distinguish the amount of lactoferrin from the total weight of the ingredient.

Have 100–200 mg servings of lactoferrin been studied in people?

Yes. Studies have used 100 mg daily in children and 200 mg daily in adults. Those amounts correspond to the product’s stated servings of one sachet for a child and two for an adult. Matching an ingredient amount does not mean the finished product has demonstrated the same outcomes; follow the label’s age and use instructions.

Why combine lactoferrin with colostrum?

Lactoferrin is one specific milk protein. Colostrum contains a broader mixture of proteins and immunoglobulins. Combining them provides a defined lactoferrin serving alongside other components of colostrum.

Why use four types of prebiotic fiber?

Fibers differ in structure and can be used by different groups of gut microorganisms. FloraProtect® combines acacia gum, galactomannan, arabinogalactan, and xylooligosaccharides (XOS), providing a mix rather than a single fiber type.

Is lactoferrin an iron supplement?

No. Lactoferrin is an iron-binding protein, not a conventional iron supplement. It has been studied in relation to iron metabolism, but confirmed iron deficiency or anemia requires an assessment of the cause and appropriate treatment. Do not substitute lactoferrin for prescribed iron treatment.

Does the product contain milk, and is it suitable for a milk-protein allergy?

Both lactoferrin and colostrum come from cow’s milk. The product is not suitable for people with a milk-protein allergy unless their treating clinician specifically advises otherwise. Milk-protein content and lactose content are different issues; the latter requires a product specification.

Why mix the powder into lukewarm rather than hot liquid?

Lactoferrin and some colostrum proteins are sensitive to heat. Prepare the product in lukewarm liquid or food as directed, rather than very hot tea or milk, to help preserve the proteins’ properties.
