First of all, we should distinguish between cod liver oil, natural cod liver oil and vitamin AD agent, and we should not confuse them!

Natural cod liver oil: mainly health care products. The common ratio of vitamins A and D in health cod liver oil is 10: 1. If the ratio of vitamin A to vitamin D is unreasonable, vitamin A may be supplemented too much, while vitamin D is insufficient, which cannot prevent diseases. The optimal absorption rate of infant vitamin AD is 3: 1.

Vitamin AD agent: commonly known as "cod liver oil", commonly used in China is ice, which is a synthetic compound preparation. The ratio of vitamin A to vitamin D is 3: 1.

Therefore, vitamin AD can be supplemented, but it is not recommended to eat natural cod liver oil. Don't be fooled by selling health products.

When do you start eating? How big is it?

Vitamin d can be eaten two weeks after birth, and the amount varies from country to country.

The American advice is to supplement it after birth until adolescence.

Canada and Britain suggest lifelong supplementation (because of short sunshine hours).

China suggests that infants under 2 years old should be supplemented with vitamin D 400 IU/ day.

What about after 2 years old? I think it can be made up for life, especially for people who live in the north and don't get much sunshine. If there is plenty of sunshine in the south and you often bask in the sun, you don't need to add it.

Can vitamin AD be poisoned?

Toxic dose of vitamin AD in reference intake of dietary nutrients for residents and children in China;

Taking more than 300,000 international units of vitamin A at a time may lead to acute poisoning;

Taking about 500-65438+ ten thousand international units every day for more than 6 months may cause chronic poisoning.

Taking 20,000-50,000 international units of vitamin D every day for several weeks or months can lead to poisoning.

Take Yikexin as an example, which is equivalent to taking hundreds of Yikexin at a time, or taking dozens of capsules every day for half a year, which may cause chronic poisoning, but as long as it is fed normally, it is obviously impossible.

Pediatrician Bao Lanxiu

Chief Physician of Pediatrics of Peking Union Medical College Hospital, Professor of Pediatrics of Peking Union Medical College Hospital, Director of China Eugenics Association, and Chairman of Child Development Professional Committee. Willing to popularize parenting knowledge, infant feeding, premature infant intervention and other knowledge.

I personally recommend buying similar medicinal vitamin AD such as Yikexin, mainly from the following questions.

First of all, we buy cod liver oil or vitamin AD to supplement vitamin A and vitamin D, both of which have specific structural formulas. There is no difference between cod liver oil and drug synthesis, but the quality requirements of drugs in China are much higher than those of health care products (in terms of vitamins, the requirements for vitamin dose concentration will be higher), that is to say, buying drugs can better ensure that the real dose you supplement is the marked dose (of course, it is not absolute, but only probability).

Secondly, the Nutrition Society of China mentioned in the infant feeding guide from July to 24 that it is not easy to add complementary food before April, because it will increase the probability of infant allergy (supported by other similar studies). As a natural food, cod liver oil must have natural allergenic ingredients, and premature contact with children may lead to fish allergy in the future. The medicinal ingredients are clear, namely vitamins and refined vegetable oil. Although vegetable oil is also a natural food, after refining, there is basically only a single oil component, and the impact is relatively small.

Third, for non-premature infants aged 0-6 months, the general supplement amount can be controlled at about 400 ug of vitamin D, and it is relatively more reasonable to have separate vitamin D drops to choose from. As for vitamin A, there is no need to supplement it. Although vitamin A is a nutrient that people in China generally lack, as long as complementary foods such as liver mud and carrot mud are reasonably added in June, there will be no shortage of hair.

The research shows that the effective rate of Ikhin for rickets is 97.6%, and that of cod liver oil is 73.2%. It shows that the overall curative effect of Yikexin on vitamin D deficiency rickets in infants is better than cod liver oil.

Due to the limitation of its technology and packaging conditions, cod liver oil is easily affected by external factors such as light and air during storage. If it is not properly preserved, the drug can be oxidized and decomposed, reducing its content (potency). The proportion and dosage of cod liver oil are not suitable for infants. Compared with the traditional vitamin D preparation, the technology and packaging of Yikexin are more scientific, which significantly improves the stability of the drug. Overcomes the deficiency of cod liver oil pill in content ratio and dosage in infant medicine, and is more suitable for infant use.

Yikexin overcomes the shortcomings of Yugan Oil Pill and has the characteristics of accurate content, convenient administration and stable curative effect. It is worthy of recommendation and application in the clinical treatment and prevention of vitamin D deficiency rickets in infants.

There are many factors leading to rickets, and drug treatment alone is not enough. Only by strengthening pregnant women's awareness of self-care, publicizing scientific parenting knowledge and early comprehensive prevention and treatment can we fundamentally prevent and control the occurrence of rickets, reduce the incidence of rickets and reduce the harm of rickets to baby health.

The baby should be supplemented with vitamin D every day from the first day 15, and the recommended intake is 400 iu/d. ..

Why do you want to add? What's the use of vitamin D? Vitamin D is an indispensable nutrient to promote bone health. It can help the intestine absorb calcium and make bones strong.

As long as the baby has enough milk every day, there is no need to add any supplements.

I believe that many parents, like me, are familiar with Icexin, a drug used to prevent and treat vitamin A and vitamin D deficiency, and have bought it for their children. But some parents choose to give their children cod liver oil, so which is better, cod liver oil or Yi Kexin?

Is it better for a three-month-old baby to supplement vitamin D to eat that kind of cod liver oil or to take Yi Kexin medicine? First of all, let's look at the difference between cod liver oil and Yi Kexin before making a judgment.

1, the AD ratio of cod liver oil and Yikexin is different.

Natural cod liver oil contains A 1500 units of vitamin A and D 150 units of vitamin D per gram, and the ratio is 10: 1, which is not suitable for children aged 0-3 years. High vitamin A and low vitamin D often lead to excessive intake of vitamin A and insufficient intake of vitamin D..

The proportion of AD in Yikexin is 3: 1, which is in line with the proportion of children aged 0-7 taking vitamin AD stipulated by the National Nutrition Society. Can meet the baby's daily needs, play an effective role in preventing vitamin AD deficiency, and the effect is better.

2. Cod liver oil and Yikexin come from different sources.

Cod liver oil is mostly shark liver oil or cod liver oil, which contains vitamin A, vitamin D, vitamin E, DHA, fish oil and other ingredients. It belongs to the category of health food and has no therapeutic effect on disease prevention.

Yikexin is a national medicine quasi-word product approved by the US Food and Drug Administration. It is a preventive OTC product and can be bought in regular pharmacies and hospitals. As a drug, the national supervision is strict, the dosage is also required, and it is relatively safe.

3. Cod liver oil and Yikexin have different tastes.

Cod liver oil generally has a strong fishy smell, which the baby doesn't like very much, but Yi Kexin uses sweet peanut smell instead of fishy smell, and the dosage is reasonable, which is more acceptable to the baby.

By comparing the difference between cod liver oil and Yikexin, parents and friends can know that Yikexin should be the first choice if they want to supplement their baby with vitamin D. Because compared with cod liver oil, Yikexin is more scientific in proportion, more accurate in content, more acceptable to babies, and more suitable for babies to take supplements every day to meet their physical needs and care for their healthy growth.

Is ekxin and cod liver oil the same thing?

Can I still eat cod liver oil after eating Yikexin?

Only vitamin d or Icahn?

Oh, look at this mess!

So let's talk about this problem briefly today!

Methamphetamine and past cod liver oil meth.

Yikexin is a brand name, commonly known as vitamin AD drops, containing vitamins A and D, and the AD ratio is 3: 1, with two specifications, 0- 1 year and 1 year or older. Over-the-counter drugs with accurate prescriptions are common in hospitals, maternal and child health centers, community health service centers and pharmacies, and general doctors will also recommend daily preventive supplements to their babies.

fish liver oil

Cod liver oil is the name of this category. There are two kinds: medicinal cod liver oil, which contains vitamins A and D, and the AD ratio is 10: 1. Usually the content of A is 5000- 10000 units, which is almost eliminated in the market; Food cod liver oil contains vitamins A and D, and some other ingredients such as fish oil are added. It is sold in a maternal and infant store, and the advertising ratio is 10: 1. If it is 3: 1, it must be post-preparation and cannot be extracted naturally. This kind of cod liver oil generally belongs to food grade, with low AD content, no disease prevention effect and fishy smell.

We talked about it over a hundred years ago. As we all know, vitamin AD is very important to human body. It was discovered more than 100 years ago and was originally extracted from the liver of a big fish. At that time, it brought great help to human health.

However, the natural proportion of AD in the liver of big fish is 10: 1, and the purification process is not advanced, so it is easy to contain chemical residues and impurities. With the increasingly serious marine pollution, the liver of big fish located in the upper layer of the biological chain is also easy to contain heavy metals, which is difficult to remove and has a great impact on human health.

With the development of pharmaceutical industry, people can produce more pure vitamin A and vitamin D, and mix them in a more appropriate proportion, so vitamin AD drops came into being. It is safer, more reasonable in content, and has more clear research support, which can reduce the possibility of rickets and night blindness in infants. With the development of research, it is also found that they have more and more functions, especially for infants in the stage of rapid growth and development, which can improve immune function and promote height.

Therefore, for the baby, the dietary source of vitamin AD is limited, and the lack of it is risky and has great health risks, so it needs to be supplemented every day. The content of mature vitamin AD drops (such as Yikexin) in the market conforms to the preventive supplementary dose recommended by national authorities, and cod liver oil cannot be used as a substitute.

Of course, there are still many people who habitually refer to Yikexin as cod liver oil, but they are completely different! Mothers have to tell!

Only vitamin d or Icahn? Yikexin supplements vitamins A and D.

Vitamin A deficiency is still widespread in China, with a significant gap with developed countries. Vitamin A is related to all aspects of baby's health, such as reducing the incidence of anemia, improving immune function, promoting height development, promoting vision and intellectual development. Supplementing in small doses every day is safe and reliable, and it is not affected by diet, cooking methods and absorption rate, so the baby will be healthier, which is of great significance in the field of children's health care.

Chronic vitamin A poisoning needs 50-65438+10,000 international units every day, taking it continuously for more than 6 months!

So for example, if what you eat every day is the content of iKexin, you don't need to worry about this problem. Since there is no excessive risk and it can bring health benefits to the baby, why worry!

To sum up: Yikexin is a vitamin AD drop, not cod liver oil, nor can it be replaced by cod liver oil, nor does it need to be taken together with cod liver oil!

Babies aged 0-3 need to take vitamin AD drops instead of cod liver oil. The dose of cod liver oil is not enough, which is a health hazard!

China baby is more suitable for AD children's walking!

Since the child was born 2 weeks ago, he has been taking VD supplements for more than 3 years.

From 3 to 4 months after birth, give concentrated vitamin D, 400 units a day.

Source and supply of vitamin D: animal liver, cod liver oil and eggs. The content of milk is not high, but the proportion of calcium and phosphorus in human milk is appropriate, and the absorption rate of calcium is high, so breast-fed babies are less likely to suffer from rickets, while the absorption rate of calcium in milk is low, so artificial feeding needs to supplement foods rich in vitamin D. In addition, take children to the sun and eat more eggs, meat and milk. Take cod liver oil as required.

Look at the results first: the baby who is allergic to fish can take vitamin D or riconazole, and the baby who is not allergic can take vitamin D, cod liver oil or riconazole.

First of all, vitamin D is different from cod liver oil and Yikexin. Vitamin D contains vitamin D2, vitamin D3 and other vitamin D families. Cod liver oil is extracted from the liver of non-toxic fish, and its main components are vitamin A and vitamin D; Yikexin is a kind of synthetic vitamin A and vitamin D drops, belonging to drugs. Both have the effects of promoting calcium absorption and preventing rickets in infants. Cod liver oil and Yikexin can also prevent infants from vitamin A deficiency, because they contain vitamin A. ..

As for what a three-month-old baby should supplement, it can be supplemented according to the actual situation. As long as mother supplements enough vitamin A in her diet, she only needs to supplement vitamin D(400IU/d). If vitamin A in breast milk is insufficient, vitamin AD drops such as cod liver oil or Yikexin can be supplemented. If it is mixed feeding or artificial feeding, it needs to be supplemented appropriately according to the amount of vitamin D obtained by the baby from milk powder (it can be supplemented once every two or three days), as long as the average daily total amount reaches 400 international units.

As for cod liver oil or Iconoseki, first of all, cod liver oil is extracted from fish liver, which contains other ingredients besides vitamin A and vitamin D, so babies who are allergic to fish should use it with caution, but when buying cod liver oil, you must choose a more formal manufacturer with a small blue hat (health care products) to ensure the quality.

At present, there are vitamin AD preparations specially made for infants, such as Yikexin, which are scientifically matched (VA:VD=3: 1) and are suitable for infants to absorb. Just give them the instructions or the doctor's instructions.

First of all, what yomi's mother wants to say is that cod liver oil and vitamin AD drops are not the same thing! It is recommended to supplement vitamin D with vitamin AD drops (such as Yikexin)! It is recommended to supplement vitamin D with vitamin AD drops (such as Yikexin)! It is recommended to supplement vitamin D with vitamin AD drops (such as Yikexin)! Say the important things three times.

We all know that vitamin D is an indispensable nutrient to promote bone health. It can help the intestine absorb calcium and make bones strong. Especially when the baby is in a period of rapid growth, the importance of vitamin D is particularly important. For example, if you take your child to a physical examination, the doctor will check the child's fontanel. If the fontanel is too big, the doctor will suggest calcium supplementation and tell you that vitamin D can't be broken.

Why do you recommend yikexin as a tonic instead of cod liver oil as a health care product?

First of all, the national food and drug testing stipulates the safety ratio (VD: VA = 1: 3), which cannot be guaranteed in health care products. Many health care products will increase the proportion of vitamin A and choose to reduce the content of vitamin D. Therefore, if health care products are supplemented, there may still be insufficient intake of vitamin D.

Secondly, compared with drug testing, there are still shortcomings in health care products testing. Recently, many liver and kidney injuries have occurred due to long-term use of health care products. It is not recommended to supplement health care products for children.

Of course, there are still a large number of parents who think that vitamin A supplementation is unnecessary, because foreign doctors suggest that vitamin D supplementation is not necessary. Therefore, I will not choose domestic Didi such as Yi Kexin.

But in fact, the vitamin A level of breast milk samples in China is at a low level internationally. A survey of breast milk samples from 0/5 day to 3 months after delivery in many countries in the world showed that the average concentration of vitamin A in breast milk was between 297 and 825 μ g/L, and the average concentration of meta-analysis was 444.014.6 μ g/L. The content of vitamin A in breast milk samples in China was the lowest, with 297 μ g/L. According to the latest research results of Shandong University last year, the average daily intake of vitamin A for lactating mothers in China is only 50% of the recommended intake.

Therefore, according to the results of breast milk testing in China, it is actually necessary to supplement the baby with vitamin A.

Perhaps, some parents will worry about vitamin A poisoning online. According to the data of the World Health Organization, many poor countries and regions adopt the method of supplementing vitamin A in large doses, that is to say, they have not taken a large amount of vitamin A in a short time. For example, add 50000 IU (international unit) of vitamin A to the baby once or more within six months.

The study found that this method of supplementing vitamin A in a large amount in a short time is simple, easy to operate and low in cost. However, because the concentration of vitamin A in the blood rises too fast in a short time, there will be adverse drug reactions. In other words, if you supplement a large amount of vitamin A to your child in a short time, there may be adverse reactions.

However, at present, the method of daily supplement with small dose is basically adopted in China. For example, the vitamin A content of 0- 1 year-old green gourd Yikexin is 1500UI. Experts say that the daily dose of vitamin A within 1 year should not exceed about 1500 IU. As long as the supplement amount is within this tolerable maximum intake range, there are few records of adverse reactions. In other words, compared with short-term full-dose surprise supplement, small-dose daily supplement is safer. Therefore, if you take a large dose of vitamin A to supplement the adverse reactions, it will be more worthwhile as a reason to refuse to supplement vitamin A to your baby!

So to sum up, it is recommended to supplement Yikexin instead of cod liver oil!

Three-month-old babies are advised to supplement vitamin AD preparation. Cod liver oil belongs to health care products and is not recommended.

The cod liver oil mentioned by the subject should refer to the cod liver oil of health care products. The ratio of vitamin A to vitamin D in this cod liver oil is generally 10: 1. Yikexin 0- 1 year-old vitamin AD preparation belongs to medicines, and each capsule contains A65438+D500 units of vitamin D, that is, the ratio is 3: 600.

Some parents are worried that the vitamin AD preparation that the baby takes for a long time will be poisoned?

Both vitamin A and vitamin D are fat-soluble vitamins, and chronic poisoning will occur if they are taken excessively for a long time. Early manifestations include joint pain, swelling, itchy skin, chapped lips, fever, headache, vomiting, constipation, diarrhea and nausea.

As long as the total daily intake does not exceed the maximum tolerable intake (UL), it is safe for infants to supplement vitamin A and vitamin D.. For infants aged 0- 1 year, the UL values of vitamin A and vitamin D are 2000 international units and 800 international units per day, respectively. As long as parents give it to their babies according to the drug instructions, it will generally not be overdosed.
