Most studies have found that more than 600 IU is needed, even for normal births
Various studies also adjust the dose with infant weight
- Search Vitamin D Life for "VERY LOW BIRTH WEIGHT" 335 items as of May 2018
- Many preemies need at least 800 IU of vitamin D – RCT May 2013
- 1600 IU was the conclusion of three JAMA studies
- Preemies need 1,000 IU of vitamin D – RCT Sept 2017
- Premature infants (30 weeks) who got 800-1000 IU of vitamin D were much healthier – March 2017
Infant-Child category starts with
- No consensus on MINIMUM International Units (IU) for healthy infant of normal weight
- 400 IU Vitamin D is no longer enough
Was OK in the past century, but D levels have been dropping for a great many reasons.
FDA doubled the vitamin D level in milk in July 2016 - No consensus: range is 600 to 1600 IU – based on many randomized controlled trials
- Fewer infants were vitamin D deficient when they got 800 IU – RCT Feb 2014
- 1600 IU was the conclusion of three JAMA studies
1000 IU recommended in France and Finland – 2013 - appears to be a good level
A recommended level may be agreed upon around the world by 2020 - 5X less mite allergy after add vitamin D
- Child bone fractures with low vitamin D were 55X more likely to need surgery
- 75 % of SIDS had low vitamin D
- Children stayed in ICU 3.5 days longer if low vitamin D – Dec 2015
- 5 out of 6 children who died in pediatric critical care unit had low vitamin D – May 2014
Having a good level of vitamin D cuts in half the amount of:
- Asthma, Chronic illness, Doctor visits, Allergies, infection
Respiratory Tract Infection, Growing pains, Bed wetting
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.
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, oil
One capsule of 50,000 Bio-Tech Pharmacal Vitamin D could be stirred into monthly formula
this would result in ~1,600 IUs per day for infant, and higher dose with weight/age/formula consumption

Study design
Very low birth weight infants had measurement of 25-hydroxyvitamin D status and markers of calcium and bone health from birth to term age. Piecewise linear regression modeling was performed to identify a 25-hydroxyvitamin D threshold associated with stable parathyroid hormone concentration and bone mineralization.Results
In a cohort of 89 infants at term age, femur BMC and density increased linearly with 25-hydroxyvitamin D status until reaching a threshold of 48 ng/mL and 46 ng/mL, respectively. Parathyroid hormone status decreased as vitamin D status increased until reaching a plateau at 25-hydroxyvitamin D of 42 ng/mL.Conclusion
Preterm infant vitamin D status was significantly associated with PTH status and femur mineralization with suggestion that achieving a specific 25-hydroxyvitamin concentration is associated with optimal calcium homeostasis and femur bone mineralization.From the PDF
The median (interquartile range) intake through the study were- vitamin D 609 (519,678) IU/day,
- calcium 182 (141, 244) mg/kg/day
- phosphorus 122 (85, 165) mg/kg/day
