Many parents know that vitamin D can promote calcium absorption and is very important to the growth and development of the baby. Doctor Clove has also sent an article to teach you how to supplement vitamin D for the baby before.
But! There is always a but! Dr. clove knows that one article cannot solve all the problems… after the article was launched, many parents came to ask questions, such as [sun exposure can supplement vitamin d, why do you need to eat extra? ] [Can you be poisoned if you eat too much? ] …
Dr. Clove collected everyone’s questions and trotted to ask nutritionist friend and hot mom Li Liangli ~
It is enough to bask in the sun. Why do you need to supplement D?
Dimension D is not something you can supplement by basking in the sun, you can supplement it if you want… If you want to obtain enough Dimension D by basking in the sun, you need to meet:
- Sufficient sunlight skin exposure range is large enough sunlight exposure time is long enough
However, these conditions are affected by local seasons, latitude of residence, environmental pollution, etc. They are not necessarily useful if they are not exposed to the sun.
And even if all these conditions are met, don’t you worry that the high-energy blue light in the sun will damage the baby’s retina? Moreover, the baby’s skin is very delicate. For babies under 6 months old, they are absolutely infertile and directly exposed to the sun.
Compared with basking in the sun, vitamin D supplement is less difficult and more reliable. Do you have to take your baby to the sun?
As for some people who are worried that the vitamin D supplement is not good, Dr. Clove should talk about the data.
The maximum tolerable intake of vitamin D is:
- Under 4 years old, 800 IU per day, 4-7 years old, 1200 IU per day, 7-11 years old, 1800 IU per day, over 11 years old, 2000 IU per day
Studies abroad have confirmed that when the daily intake of vitamin D exceeds 50,000 IU, the symptoms of excessive intake of vitamin D will be caused.
In 2013, the Chinese Nutrition Society recommended 400 IU of vitamin D per day. According to this amount, there will be no poisoning, no poisoning, no poisoning!
Why should vitamin D be eaten to adulthood?
In the past, child care doctors often suggested infants to supplement vitamin D to 2 years old, which was considered from the perspective of preventing rickets.
However, if we look at the needs of long-term physical health and growth and development, even adults over 2 years old need to supplement vitamin D to promote bone development and increase intestinal absorption of calcium and phosphorus.
The recommended intake of vitamin D proposed by the Chinese Nutrition Society in 2013 is 400 IU per day, which is supplemented by this amount every day. There will be no poisoning, no poisoning, no poisoning! It will only be good for health!
Can 500 units of vitamin D be poisoned every day?
There are very few simple VD3 in China. Even if there are, there are more than 500 units. Is this quantity safe?
Important things Dr. Clove said several times. The recommended intake of vitamin D proposed by the Chinese Nutrition Society in 2013 is 400 IU per day, but the maximum tolerable intake of vitamin D is 800 IU per day under 4 years old, 1200 IU per day for 4-7 years old, 1800 IU per day for 7-11 years old, and 2000 IU per day for 11 years old and above. Therefore, even if you eat 500 international units of vitamin D every day, it is safe and will not be poisoned, poisoned, poisoned…
Why don’t foreign countries need to supplement D?
This is probably just [legend], [some people say]. If foreign countries really don’t need to supplement, how can there be so many imported D products?
No matter at home or abroad, pediatricians generally recommend that babies should be supplemented with vitamin D from 2 weeks of birth.
The physiological needs of vitamin D for people of different ages released by the American Institute of Medicine (2010) are:
- 400 IU per day under 1 year old, 600 IU per day for 1 ~ 70 years old and 800 IU per day for over 70 years old.
Vitamin A + D mixture, can vitamin A poisoning?
Although it is not recommended to supplement vitamin A additionally for babies, there are very few domestic manufacturers that produce individual vitamin D, most of which are mixtures of vitamin A + D. Is it bad for babies to supplement vitamin A additionally?
In fact, vitamin A will only be poisoned if it is supplemented with more than 10,000 IU per day for a long time. In general, the content of vitamin A in vitamin A + D mixture is within the normal range, and parents need not worry about excessive problems.
However, Dr. Clove still does not quite understand why it is impossible to produce simple vitamin D supplements… Vitamin A + D mixture is not recommended abroad. They generally believe that excessive intake of vitamin A will increase the risk of cardiovascular diseases and liver injury, so separate vitamin D drops are also the main drugs on the market.
More sun exposure is indeed a simple and effective measure to supplement vitamin D, but it is also necessary to take into account the characteristics of different seasons, climate, regions, environmental pollution, etc., and to avoid direct sun exposure for babies within 6 months.
In short, vitamin D supplement needs to be adjusted according to different regions, different seasons and different climates. In the specific situation in China, it is still recommended to supplement 400 IU of vitamin D to babies every day.
