OBJECTIVE: Vitamin D status in infants depends on supplementation. We examined the vitamin D status in relation to supplementation dose and scheme in infants.
PATIENTS AND METHODS: One hundred thirty-four infants age 6 months and 98 infants age 12 months (drop out 27%) were investigated. Vitamin D intake (diet, supplements), anthropometry, and 25-hydroxyvitamin D (25-OHD) serum concentration at the 6th and 12th months were assessed.
RESULTS:Vitamin D intake of 1062 ± 694 IU at the 6th month was not different from that at the 12th month (937 ± 618 IU). Vitamin D intake expressed in international units per kilogram of body weight decreased from 141 ± 80 IU/kg at the 6th month to 93 ± 62 IU/kg at the 12th month (P < 0.0001), which was associated with a reduction in 25-OHD from 43 ± 20 ng/mL to 29 ± 12 ng/mL, respectively (P < 0.0001).
In the subgroup of everyday supplemented infants (n = 43), vitamin D intake decreased from 143 ± 88 IU/kg at the 6th month to 118 ± 60 IU/kg at the 12th month (P < 0.05), which coincided with a reduction of 25-OHD from 40 ± 19 ng/mL to 32 ± 13 ng/mL (P < 0.01).
In the subgroup with variable supplementation habits (n = 32), vitamin D intake decreased from 146 ± 79 IU/kg to 77 ± 56 IU/kg (P < 0.001), which was associated with a reduction of 25-OHD from 42 ± 21 ng/mL to 25 ± 8 ng/mL (P < 0.0001). 25-OHD concentration change between the 6th and the 12th months negatively correlated with the 25-OHD level assessed at the 6th month (r = -0.82; P < 0.0001).
CONCLUSIONS: Vitamin D supplementation of infants should consider their rapid body weight increment.
We postulate vitamin D daily dose close to 100 IU/kg body weight as favorable for infants up to age 12 months.

- 1000 IU per 25 lbs (recommended by some in the US) is about 1% different than 100 IU/kg
- The Red line is the average weight of children at that age.
- This article recommends this amount up to age 12 months, others recommend it for up to age 12 years
- Many Veterinary recommend this amount for cows, horses, etc. (file, not web page)

- One study gave infants 50,000 IU very two months (833/day)
- Most mothers still do not supplement infants with vitamin D – July 2010
- 400 IU vitamin D daily was enough for most infants – Jan 2011
- Only about 10 % of breastfed infants get even the minimum recommended vitamin D – April 2010
- Infants getting 1400 IU vitamin D weekly grew better – May 2011

They reported a significant decrease in type I diabetes decades later - NO toxicity, hypercalification, etc. etc.!
After infant stops drinking formula/milk, be sure to supplement with vitamin D - fruit juice is rarely fortified with vitamin D.
Note: that typically happens between age 1 and 3Recommend 100 IU of vitamin D per kg of infant - Poland July 2011
