The benefits of adequate lactoferrin nutrition (2023)

lactoferrinais a naturally occurring protein in the milk of humans, cows and other mammals. It is also found in other bodily fluids such as saliva, tears,culture, EGalle.Lactoferrin has antiviral and antibacterial properties and helps the body transport and absorb iron.

In humans, the highest concentrations of lactoferrin are found inColostrum, which is a very nutritious first form of breast milk produced shortly after the baby is born.Babies can get plenty of lactoferrin from breast milk, while adult food sources are available.

Some people take lactoferrin supplements for its supposed antioxidant andAntiphlogistikumBenefits. While the lactoferrin used in supplements usually comes from genetically engineered rice, it can also come from cow's milk.

This article discusses lactoferrin's purported uses and benefits, side effects, precautions, interactions, dosage, and dietary sources.

Dietary supplements are not regulated in the United States, which means that the Food and Drug Administration (FDA) does not approve them for safety and effectiveness before the products are marketed. Whenever possible, choose a dietary supplement that has been tested by a reputable third party, such as the USP, ConsumerLabs, or NSF.

But even if supplements are third-party tested, that doesn't mean they're necessarily safe for everyone or generally effective. It's important to talk with your doctor about any supplements you're considering taking and learn about potential drug or supplement interactions.

Security aspects:There are few side effects associated with lactoferrin. Taking too much lactoferrin can cause an upset stomach, skin rashes, and loss of appetite.

Alleged use of lactoferrin

The use of dietary supplements should be individualized and reviewed by a healthcare professional, such as a registered dietitian, pharmacist or healthcare professional. No dietary supplement is intended to treat, cure or prevent any disease.

Lactoferrin has a wide range of intended uses. As a supplement, it is believed to have antioxidant, antiviral, and antibacterial properties. Researchers are also starting to look into lactoferrin's possible role in immunity.COVID 19in the head.

Many believe that lactoferrin can support thisimmune system. However, most current research has been done in the laboratory rather than humans, and more evidence is needed in most cases.

The following is a look at the available research on the purported uses of lactoferrin.


Lactoferrin can protect the body from harmful organisms that cause bacterial, viral and fungal infections.

bacterial infections

It has been suggested that the binding effect of lactoferrinEisenprevents bacteria from using iron for transport throughout the body.

Although results are mixed, lactoferrin has been studied for its use inHelicobacter pylori (H. pylori)-Infection, a type of bacterial infection known to cause stomach ulcers. In a laboratory study, cow lactoferrin was found to inhibit the growth of H. pylori. It also increased the strength of medications commonly used to treat the infection.However, this study was performed in vitro (in a test tube in a laboratory) and not in humans.

Other laboratory studies that have focused on the use of lactoferrin for bacterial infections have found similar results, but more human studies must be done to confirm.

the viral infection

Research has examined the protective effect of lactoferrin against viral infections such asA cold,Gripe, herpes and gastroenteritis. This is believed to be achieved by preventing viruses from attaching to cells and replicating. However, the research was based on non-human animals.

There is also evidence that lactoferrin can inhibitHepatitis CInfection. Several studies have examined the connection.

In one study, researchers found that lactoferrin helped increase levels of interleukin-18, a protein that plays a key role in fighting hepatitis C. The one-year study involved 63 people with the virus, a small sample.However, it should be noted that results on lactoferrin's role in preventing hepatitis C have been mixed.

Of particular interest is lactoferrin's potential ability to prevent and treat COVID-19. Preliminary research on this topic led researchers to believe that lactoferrin could help treat asymptomatic and mild to moderate COVID-19.However, the sample size in the study was small (92 people). Larger, longer-term studies are needed before recommending the use of lactoferrin.

fungal infections

Lactoferrin is also said to have an antifungal effect.

Several animal studies have looked at whether lactoferrin can help treat fungal infections, including yeast infections.Candida. In one such study, yeast-infected mice treated with lactoferrin had less severe infections than mice that did not receive lactoferrin.

More human studies are needed on the potential role of lactoferrin in the treatment of bacterial, viral and fungal infections.

Does hepatitis C have a cure?


In one study, participants drank fermented milk containing 200 milligrams (mg) of lactoferrin or fermented milk alone daily for 12 weeks.At the end of the treatment period, those who received the milk supplemented with lactoferrin had lessAcneinjuries and lesssebum(oil) compared to those who took the placebo.

Another small study found similar results. young participants withacne vulgartook lactoferrin chewable supplements for eight weeks. At the end of the study, they had fewer acne lesions and inflammation. Dietary supplements were also well tolerated. However, the study did not include a control (comparative) group; Therefore, the results are not as reliable as those from a control group study.

While research on the bone-building benefits of lactoferrin is limited, preliminary research suggests that lactoferrin may help preventosteoporosis.

In laboratory studies and in mice, lactoferrin has been found to stimulate osteoblasts, or the cells needed to build bones. It has also been found to reduce the symptoms of osteoporosis, possibly through cell signalling. However, researchers are not sure how lactoferrin works to improve osteoporosis and whether these benefits translate in humans.

In another study, lactoferrin helped to strengthen and maintain the bones of mice whose ovaries had been removed. Removal of the ovaries is intended to control hormonal changes. These findings led researchers to believe that lactoferrin may be useful in preventing and treating bone loss that occurs due to estrogen loss, a common occurrence inmenopauseWomen. However, human studies are lacking.

As with most purported uses of lactoferrin, more human studies are needed in regards to osteoporosis. While we can learn from animal and laboratory studies, human results must be duplicated to confirm the proposed benefits.

Other uses

Other purported but less researched uses for lactoferrin include:

  • cold

In children, lactoferrin intake has been associated with decreased appetite.

serious side effects

Serious side effects have not been reported when taking lactoferrin.

However, it may be possible to be allergic to lactoferrin.

A study conducted in mice found that administration of lactoferrin into the blood or mucosal tissue can produceallergens. In the study, an allergic reaction was observed in the mice, leading to inflammation of the airways.

However, the same results have not been observed in humans. Stop using lactoferrin and see a doctor immediately if you experience an allergic reaction.
