How long should vitamin D be supplemented?
Infants 2 weeks after birth should consume vitamin D400U/d daily until 2 years of age.
For high-risk groups such as preterm infants, low birth weight infants, and twin births, vitamin D800-1000U/d supplementation is started after birth and changed to 400U/d after 3 months.
Based on a large number of studies, the American Academy of Pediatrics has found that not only infants and young children are prone to lack of VD, but most children and adolescents are also deficient, so it is recommended that VD can be supplemented until puberty.
The UK Nutrition Science Advisory Committee recommends that both children and adults can make up for a lifetime.
After the baby is 2 years old, whether he needs to continue to supplement vitamin D, the mother can make a decision according to the baby's specific situation.
There are many outdoor activities, sufficient sunshine, no need to supplement;
Long-term rainy days, haze weather, recommended supplementation;
Supplementation is recommended for cold seasons and weak ultraviolet rays, but no need to supplement if there are daily outings in hot seasons.
When going out, sunscreen will affect the synthesis of vitamin D; it is impossible to synthesize vitamin D through the sun through the glass;
Infants and adults supplementing with 400 IU of vitamin D per day is very safe.
PS: Breast milk / formula baby to supplement vitamin D?
Pure breast milk for babies
Vitamin D in breast milk is about 20 IU/L, so pure breast milk babies must supplement with additional vitamin D. Moreover, exclusively breastfed infants are under 6 months of age, for infants of this age, sunshine is not the best choice (may be sunburn), vitamin D supplementation is the best choice.
Formula-fed babies
According to the provisions of the mainland "Infant Formula", the vitamin D content in formula milk ranges from 40-100IU/100kcal, while formula milk calories are basically 60-70kcal/100mL, so that the daily formula of infants must reach almost 1L to meet the daily needs of about 400IU of vitamin D.
Therefore, if your baby does not drink 1 L of formula per day, it is still necessary to supplement with vitamin D preparations as appropriate.
Therefore, regardless of the feeding method, vitamin D supplementation is required.
Is vitamin D the more you eat, the better?
Vitamin D this thing must not eat more, eat too much will be poisoned.
For the problem that mothers are worried about "overdose of vitamin A supplementation every day", let's look at the authoritative data. The Reference Intake of Dietary Nutrients for Chinese Residents (2013 Edition) and Pediatrics clearly state:
Acute intoxication: one supplement greater than 300,000 IU;
Chronic poisoning: 50,000-100,000 IU per day for more than six months.
As long as the mothers use the dosage in strict accordance with the product instructions to supplement the baby, there will be no problem of overdose!
