All children with Vitamin D deficiency (< 15ng) were given Calcium then injected with Vitamin D 3 days later
Amazingly, the study does not seem to indicate how much Vitamin D nor Calcium was given
No mention was made of ongoing vitamin D
Injection (expensive) is generally not required
- Vitamin D deficiency in China – only 1 in 18 have even 30 ng, fewer if young or female – Feb 2015
- 2000 IU vitamin D not enough to get most Chinese to 20 ng level – RCT Feb 2015

- Type 1 diabetes helped with 50,000 IU of vitamin D every two weeks – Nov 2014
- Growing pains reduced 60 percent by monthly Vitamin D – March 2014
- Breast milk resulted in 20 ng of vitamin D for infant if mother had taken 5,000 IU daily – RCT Dec 2013
Items in both categories Loading Dose and Infant-Child are listed here:
- Growing pains reduced in 91% of children with a single dose of Vitamin D – July 2024
- High-dose Vitamin D safe for children (10,000 IU daily, 600,000 IU bolus) – meta-analysis April 2022

- Neonate loading dose of 30,000 IU vitamin D helped a lot – May 2014
- Recurrence of child pneumonia delayed by 100000 IU of vitamin D – RCT Oct 2010
- 600,000 IU of vitamin D2 every 4 months for decades in East Germany – 1987
Infant-Child category has
- 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 doubles the amount of vitamin D permitted in milk – July 2016 - No consensus: range is 600 to 1600 IU – based on many randomized controlled trials
- Review of 400 IU to 2000 IU daily and higher if non-daily
- Fewer pre-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 - 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
- Infants have gotten free 400 IU of vitamin D in Turkey since 2005, More for longer would be even better – Feb 2022
- Preemies should have vitamin D supplements – reaching an agreement – April 2021
- Vitamin D loading dose was as effective as daily dosing (rickets in this case) – RCT July 2021
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

Most children improved in 1 week
Most children had 12 to 28 ng 1 month after injection
Vitamin D is very important for children's health. Previous studies have shown that vitamin D deficiency leads to a series of diseases in adults. However, pediatricians are mostly aware of rickets caused by vitamin D deficiency in children and poorly aware of other symptoms. This study aimed to retrospectively analyze the different clinical features of vitamin D deficiency to enhance identification by pediatricians, thus minimizing misdiagnosis. In this study, we retrospectively analyzed the clinical features of vitamin D deficiency in 268 children aged 0-14 years from June 2016 to May 2018 in the Third Affiliated Hospital of Zhengzhou University. Serum 25-hydroxy vitamin D [25(OH)D] levels were determined using the chemiluminescence method.
Of the 268 cases,- 101 cases showed movement disorder (37.7 %) and
- 167 nervous system abnormalities (62.3%).
Among all cases, 6 were misdiagnosed as febrile seizures (2.23%), 5 as epilepsy (1.86 %), 2 as Tourette syndrome (0.74%), and 2 as developmental retardation (0.74%).
There were significant differences in patients with clinical characteristics of movement disorder and nervous system abnormalities partly between Pre-and post-vitamin D treatment. This analysis revealed that vitamin D deficiency occurs not only in children but also in adolescents, with diverse clinical features. Therefore, pediatricians should pay more attention to clinical different signs and symptoms, and future studies should be conducted to confirm the mechanisms of these processes.
