Did you know that a single protein found in human milk can not only support a child's immune system, but also help with iron absorption, fighting infections and regulating the gut microbiota? We are talking about lactoferrin, a remarkable component that is becoming increasingly popular both in medicine and in supplements for mothers and preschool children.
Lactoferrin is a protein that occurs naturally in the human body. It can be found, among other places, in breast milk, saliva, tears and the mucus of the digestive tract. Its key function is to bind and transport iron, which means it plays an enormous role in maintaining health.
What health benefits does it offer?
- Supports immunity – acts as the body’s natural guardian, helping to fight bacteria, viruses and fungi.
- Improves iron absorption — this may help prevent anaemia, especially in pregnant women and babies.
- The source claims that it regulates the gut microbiota by supporting beneficial bacteria, which it describes as important for digestive health.
- Has an anti-inflammatory effect — it may help alleviate inflammation in the body, for example within the digestive tract.
- Protects the oral cavity by inhibiting the growth of bacteria responsible for tooth decay and inflammation of the gums.
Although lactoferrin is particularly valuable during the first months of a child's life, its immunomodulatory properties also benefit adults. It supports lymphocyte production, regulates inflammatory responses and acts as a natural ‘guardian’ against infections. Studies have shown that regular lactoferrin supplementation may reduce the risk of upper respiratory tract infections and support the body in fighting viruses, making it a valuable dietary component during autumn and winter.
Lactoferrin in breast milk is a baby’s first line of defence
Breast milk is the best source of lactoferrin, which is why breastfeeding is so important for building a child's immune system. A newborn enters the world with an immature immune system, and lactoferrin helps them fight pathogens and develop healthy gut flora.
The source says that lactoferrin may be particularly relevant in premature babies, who are at increased risk of infection and iron deficiency.
Lactoferrin in diet and supplementation
Not everyone has a sufficient amount of lactoferrin in their body. It can be obtained through diet and supplements. It is found, among other sources, in cow's milk, although in significantly smaller quantities than in human milk.
Lactoferrin supplementation may be helpful for:
- During pregnancy — the source claims that it supports immune function, improves iron absorption and reduces the risk of anaemia.
- Children and babies – especially those who are not breastfed or have gastrointestinal problems.
- People with anaemia - improves iron absorption, which may reduce the need for supplementation with conventional iron preparations.
- People with intestinal problems – supports the gut microbiota and has anti-inflammatory effects.
How Do You Choose a Good Lactoferrin Supplement?
Various forms of lactoferrin are available on the market, most often as capsules or powder. When choosing one, it is worth considering:
- Product purity– the fewer unnecessary additives, the better.
- Dosage – should be adapted to the person's age and physiological needs.
- Origin – it is best to choose high-quality lactoferrin derived from cow's milk.
What Doses of Lactoferrin Are Recommended?
According to scientific studies, standard lactoferrin doses for adults range from 200 to 400 mg per day, while doses of 100–300 mg are recommended for pregnant women to improve iron absorption and support immunity. For babies and children, the doses are lower, ranging from 50 to 100 mg per day depending on body weight and health needs. It is worth remembering, however, that lactoferrin is a natural component of breast milk and that its concentration in colostrum, the first milk, can reach as much as 7 g per litre!
Can you overdose on lactoferrin?
Lactoferrin is a protein that is well tolerated by the body, but excessive amounts in supplements can cause digestive discomfort such as bloating or diarrhoea. Studies show that even doses of up to 2 g per day are safe, although they are not necessary for daily supplementation. The best results come from using moderate amounts of lactoferrin tailored to the body’s individual needs.
