Infant-Child category starts with

Having a good level of vitamin D cuts in half the amount of:

Need even more IUs of vitamin D to get a good level if;

  • Have little vitamin D: premie, twin, mother did not get much sun access
  • Get little vitamin D: dark skin, little access to sun
  • Vitamin D is consumed faster than normal due to sickness
  • Older (need at least 100 IU/kilogram, far more if obese)
  • Not get any vitamin D from formula (breast fed) or (fortified) milk
    Note – formula does not even provide 400 IU of vitamin D daily

Infants-Children need Vitamin D

  • Sun is great – well known for 1,000’s of years.
    US govt (1934) even said infants should be out in the sun
  • One country recommended 2,000 IU daily for decades – with no known problems
  • As with adults, infants and children can have loading doses and rarely need tests
  • Daily dose appears to be best, but monthly seems OK
  • Vitamin D is typically given to infants in the form of drops
       big difference in taste between brands
       can also use water-soluable form of vitamin D in milk, food, juice,
  • Infants have evolved to get a big boost of vitamin D immediately after birth
    Colostrum has 3X more vitamin D than breast milk - provided the mother has any vitamin D to spare
  • 100 IU per kg of infant July 2011, Poland etc.
    1000 IU per 25 lbs.jpg
    More than 100 IU/kg is probably better

Getting Vitamin D into infants
Many infants reject vitamin D drops, even when put on nipple
I speculate that the rejection is due to one or more of: additives, taste, and oils.
Infants have a hard time digesting oils, 1999  1997   and palm oils W.A. Price 1 2 3
Coconut oil, such as in D-Drops, is digested by infants. 1,   2   3
Bio-Tech Pharmacal Vitamin D has NO additves, taste, nor oil
One capsule of 50,000 Bio-Tech Pharmacal Vitamin D could be stirred into monthly formula or given once a month
   this would result in ~1,600 IUs per day for infant, and higher dose with weight/age/formula consumption

We assessed the effect of vitamin D supplementation on related biochemistry, infection and dentition of the infant. In a double-blind, placebo-controlled trial conducted in Lucknow, India (latitude 26°N), 230 mother -newborn pairs were randomised to receive, for 9 months, 3000µg/month oral vitamin D3 by the mother (group A) or 10 µg/d by the infant (group B ) or double placebo (group C).

All babies received 15 min of sun exposure (unclothed) during massage.

Infants' median 25-hydroxyvitamin D ( 25(OH)D) was lower in group C (median 45·3; interquartile range (IQR) 22-59·5 nmol/l) than in groups A (median 60·8; IQR 41·3-80·5 nmol/l (P7.5µkat/l) was significantly more frequent in group C babies (16 %) than in group A (4 %) or group B (0 %) babies. The number of days with respiratory or diarrhoeal infection by 9 months of age was higher in group C (median 46·5; IQR 14·8-73·3 d) than in group A (median 18·5; IQR 8·8-31·0 d (P<0·01)) or group B (median 13·0; IQR 7·0-28·5 (P<0·05)). We conclude that monthly maternal or daily infant supplementation with vitamin D along with sun exposure is superior to sun exposure alone in maintaining normal infant 25(OH)D at 3·5 months, and provide protection from elevated alkaline phosphatase and infectious morbidity.
