One gram of lactoferrin extracted from every 14 kilograms of milk has been proved to have the effect of enhancing immunity by animal experiments. Milk body protein is expensive in the market, and it can be eaten for a long time if economic conditions can support it.

the premise is that you must buy real lactoferrin.

so how to tell? Be sure to look at the ingredients on the box. Look at the ingredients and see how much lactoferrin is in each bag.

Generally speaking, how much milk body protein is contained in each 1g, so you need to calculate it for each bag.

finally focusing on lactoferrin doesn't mean protein powder.

Lactoferrin has a high breast milk content, so you shouldn't blindly supplement

Lactoferrin. I believe most treasure moms have heard of it. At present, all kinds of lactoferrin products are overwhelming and their efficacy is superb. However, should lactoferrin be supplemented? 1. How much lactoferrin does the baby need?

The Expert's Knowledge on Health Effects of Lactoferrin for Infants and Young Children (218) issued by the Maternal and Child Nutrition Branch of China Nutrition Society holds that Lactoferrin can prevent and assist in the treatment of infantile diarrhea, neonatal necrotizing enterocolitis, respiratory diseases and neonatal septicemia, and has a certain effect on improving anemia and promoting the growth and development of infants and young children.

So, how much should the baby eat every day?

In the expert's knowledge, we can see the following description: the dosage of lactoferrin used in various studies is different, and the difference is quite large, and the administration methods are also different, some are oral lactoferrin, and some are obtained through dairy products.

That is to say, at present, there is no recommended value for how much the baby needs every day in the diet. We can only temporarily think that the health benefits of lactoferrin in food are better than those of no milk. 2. Which foods are rich in lactoferrin?

According to Experts' Knowledge on Health Effects of Lactoferrin for Infants (218),

Lactoferrin is an iron-binding glycoprotein in the transferrin family, which exists in human milk and various secretions, with the highest content in breast milk.

Among them, the average content of lactoferrin in human colostrum is the highest, reaching 4.9g/L; After breast milk matures, the average content of lactoferrin drops by about half, which is about 2.1g/L..

Fresh milk also contains lactoferrin, but the average content is much lower, only about .1g/L, which is 2~5 times different from breast milk.

From here, we can probably see why breast milk is the best first bite food for babies, and the importance of breast-feeding has always been emphasized.

Therefore, for breast-fed babies, there is no need to worry that the baby can't eat lactoferrin, but formula-fed babies need to pay attention.

Nowadays, formula milk powder has been trying to imitate breast milk in terms of nutritional components, so lactoferrin can also be used as a nutritional enhancer.

In general, the lactoferrin content of formula milk with lactoferrin is mostly between 35 and 35~5mg/1g. According to the average value of 4mg/1g, 7mL of formula milk can consume about 36mg of lactoferrin every day, which is still far from breast milk.

the lactoferrin content of some milk powder brands is relatively high, which can reach about 45mg/1g(21mg/kj), 1 times that of other brands. But generally speaking, the price is more expensive.

But the higher the lactoferrin in milk, the better.

The amino acid sequence of human and bovine lactoferrin is only 69% homologous. Although they have similar biological activities, they are only similar after all. We need to be more careful about the effect of bovine lactoferrin and whether it has other negative effects on the baby. Therefore, it is necessary to remind mothers that they will not be superstitious about some so-called "bovine colostrum" products with high lactoferrin content.

What level of lactoferrin can produce health benefits? There is still a big difference in current research, and there is no standard. 3. Are lactoferrin products reliable?

lactoferrin can be understood as having health benefits or promoting effects on babies, but is it worse for your baby to eat less lactoferrin than other babies?

obviously, you can't look at a health problem in a limited way. For example, lactoferrin can prevent diarrhea, enteritis, septicemia, improve anemia, promote growth and so on, and other iron, zinc, calcium and VD also have it. These health problems need a balanced nutritional intake to ensure, not just one thing.

and at present, the harm caused by lack of iron, zinc, calcium and VD seems to be more clear and serious than that caused by lack of lactoferrin. Therefore, it is suggested that Bao Ma should mainly use breast milk and formula milk fortified with lactoferrin as supplementary means.

Other lactoferrin products, such as lactoferrin health food, lactoferrin solid beverage, lactoferrin modified milk, etc., are advised not to try them at will due to lack of standards, mixed products and unsuitable for babies.

Summary: Breast milk and formula milk powder are reliable ways for babies to get lactoferrin, and other lactoferrin products are not recommended to be purchased, so as not to lose more than gain.

Whether lactoferrin can be eaten for a long time depends on understanding its biological function

(1) Participating in iron metabolism

A. Carrying and promoting iron ion absorption

Lactoferrin is the only protein carrying iron ions in the body. Lactoferrin can maintain the iron balance in the body by regulating the absorption of iron by intestinal mucosal cells according to the body's demand for iron.

Clinical trials have proved that the absorption rate of iron combined with lactoferrin is four times that of iron supplementation alone. Iron deficiency anemia patients can enhance the effect of iron supplementation with lactoferrin intake.

B. Improve the bioavailability of iron and reduce the negative effects of iron supplementation

When iron is supplemented, combined use of lactoferrin can obviously slow down the stimulation of iron ions on gastrointestinal tract. Lactoferrin can improve the bioavailability of iron and promote the absorption of iron ions by regulating iron ions, which can greatly reduce the amount of available iron, avoid the stimulation of iron ions on the intestine, reduce the gastrointestinal discomfort and diarrhea of infants, and regulate the secretion of immune system and immunoglobulin.

(2) Antimicrobial function

A. Antimicrobial function

A. Iron is an essential nutrient to maintain the growth of bacteria, and lactoferrin chelates iron ions in the environment, so that bacteria die because they lose the iron ions needed for growth.

B. Inhibitory effect of lactoferrin on bacterial adhesion and invasion: Lactoferrin can inhibit bacterial adhesion and invasion to host cells and protect the body.

B. Antiviral effect

Lactoferrin is a member of nonspecific immune system, which has unique antiviral activity, mainly by directly binding with viruses or virus particles, inhibiting virus adsorption and invasion of host cells, and exerting antiviral effect.

a. Lactoferrin has broad-spectrum antiviral function, mainly including the following types of viruses: hepatitis C virus; Human immunodeficiency virus; Herpes virus; Rotavirus; Polio virus, which mainly causes polio; Other viruses.

B. Antifungal, Parasitic and Other Antimicrobial Effects

Lactoferrin kills fungi in a "fatal" way by directly combining with cells, thus playing a fungicidal role. In addition, lactoferrin has anti-parasitic activity.

C. Promoting the growth of Bifidobacterium and regulating intestinal flora

Intestinal flora is the main defense system of human health, and Lactobacillus and Bifidobacterium are prominent beneficial bacteria in intestinal flora. Lactoferrin and lactoferrin peptide can not only inhibit a variety of bacteria and viruses (such as Escherichia coli and Listeria), but also stimulate the growth of Lactobacillus acidophilus and four kinds of Bifidobacterium. Therefore, lactoferrin plays an important role in the composition of intestinal flora balance system established rapidly after birth.

(3) immunomodulation and anti-infection

A. immunomodulation

Lactoferrin has the ability to regulate innate immunity, which is considered as a part of the innate immune system of mammals and constitutes the initial rapid immune defense system of the body against foreign pathogens;

Lactoferrin can increase the activity of key enzymes that regulate the proliferation and differentiation of immune cells;

Lactoferrin can regulate the activity of macrophages, promote the proliferation of lymphocytes, stimulate the synthesis and secretion of lymphocytes, and up-regulate the collective immune system.

Lactoferrin can promote the differentiation and maturation of lymphocytes and enhance immune function.

Lactoferrin can promote the cell to secrete immunoglobulin or cytokine, thus improving the immunity of the body.

B. Anti-infection

A. Anti-infection related to immune regulation: After lactoferrin binds to the cell surface of immune cells, it induces humoral immune response to participate in anti-inflammation. At the same time, lactoferrin also enhances the anti-infection ability of the body by enhancing the cytotoxicity of NK and monocytes.

antioxidant effect

a. antioxidant effect and mechanism of lactoferrin: lactoferrin can block the generation of oxygen Fe3+ radicals, inhibit the lipid oxidation reaction caused by iron and subsequent tissue damage, and play an antioxidant role, thus achieving the purpose of preventing and treating atherosclerosis and coronary heart disease.

B. As a cell growth factor, LF lactoferrin can promote the proliferation and differentiation of primordial osteoblasts, reduce the apoptosis of osteoblasts, inhibit the proliferation of osteoclasts, and contribute to the bone growth and development of infants.

(5) Anti-tumor

Although lactoferrin can promote the proliferation of normal cells, it can prevent rather than stimulate cancer cells. Lactoferrin and its degradation products can not only reduce the growth of solid tumors, but also inhibit the metastasis of tumor cells in vivo. This effect of lactoferrin is due to the fact that lactoferrin can strongly inhibit vascular endothelial factors and tumor-mediated angiogenesis in vivo, thus inhibiting tumor metastasis caused by it. Therefore, lactoferrin can play an anti-tumor role in many ways; Achieve the purpose of preventing and treating tumors.

lactoferrin can also cooperate with various antibiotics and antiviral drugs to reduce the dosage of drugs, reduce the damage of antibiotics or antifungal agents to human liver and kidney function, and at the same time enhance the sensitivity of microorganisms in the body to drugs and reduce the occurrence of drug resistance.

6. Main functions of lactoferrin

(1) Improving immunity

A. Promoting the production and activity of immune cells;

B. promoting antibody production;

C. capture the iron ions of pathogenic bacteria and make them die;

(2) Promoting the absorption of iron

A. Lactoferrin is the only protein carrying iron ions in the body;

B. Improve the absorption rate of iron, which is more than 4 times that of iron supplementation alone.

Based on the functions and functions of lactoferrin, we can know that lactoferrin is indispensable in human body. Lactoferrin is a kind of protein extracted from milk and also exists in breast milk, so it is very safe and can be supplemented for a long time.

It should be noted that the intestines of infants (-3 years old) are not mature, and the National Health and Family Planning Commission has a clear regulation on lactoferrin: the addition of lactoferrin should not exceed 1 mg per 1 grams of food. Pay attention to the content of lactoferrin when buying.

it's my pleasure to answer your question.

Lactoferrin can improve children's immunity. If the baby is breast milk and has good resistance, it is not recommended to give it to the baby. If the baby's resistance is poor, it needs to be eaten, but it is not recommended to eat for a long time, for fear of developing dependence. The baby occasionally has a runny nose and cough, which is also the baby's constant improvement of his immune system, so the mother doesn't have to worry too much.

I wish you a happy life

Hello, I'm glad to answer your question. Ferritin can supplement iron, enhance immunity, sterilize and resist virus. As for whether to eat lactoferrin for a long time, you should choose under the guidance of doctor's advice.

The baby's resistance mainly depends on three aspects: nutrition, exercise and medicine! Lactoferrin in nutrition is only one aspect, and attention should be paid to intestinal health and iron and zinc intake; In addition, the baby should exercise more, such as swimming, walking, playgrounds, etc., and the drugs should be less hormonal. Lactoferrin can be eaten for a long time without side effects, but it is best to mix it with probiotics and zinc, and the effect is better! In terms of brand, you can look at Chi Genyi's peptide Cote and Zhilingtong's whey protein, with high lactoferrin content!

It is not recommended to eat for a long time, but you can eat for several months, mainly depending on your own financial resources.

I don't think it is necessary to eat all the time, as long as children are normal.

Lactoferrin is an important non-heme iron-binding glycoprotein in milk, and it is a monomeric glycoprotein with bactericidal activity in neutrophils.

lactoferrin mainly exists in colostrum, which mainly plays the role of regulating immunity and resisting pathogenic microorganisms.

Lactoferrin can be used as a nutritional additive for adults or infants.

If the baby's resistance is relatively poor, you can eat it properly, but in principle, it is not recommended to eat it for a long time.

This precious mother should be given lactoferrin for a long time because of her baby's poor resistance. Lactoferrin is an active guardian protein with high content in breast milk and an important component to protect her baby's resistance. However, in general milk powder, the content of lactoferrin is very small, so the intake of lactoferrin decreases after milk transfer, and the baby's immune system is not perfect, so it is best to add some extra lactoferrin to strengthen the resistance ~ so it can be drunk for a long time without any side effects. As for the brand, I recommend the lactoferrin 4 of Baoleber. On the one hand, it is because Baoleber has a good reputation, and it is also original in New Zealand. It is also very convenient to buy, and it is very convenient to buy it in a pro-mother and baby store. On the other hand, the lactoferrin content of this lactoferrin 4 is high, reaching 4mg/1g, which is four times higher than that of other brands on the market! In addition, α lactalbumin and immunoglobulin are specially added, which adds a boost to improving immunity. So my family not only drinks it for babies, but also for adults, especially the elderly, to improve their immunity. After all, good health is so important!
