To evaluate the effects on serum 25(OH)D and bone mineralization of supplementation of breast-fed Hispanic and non-Hispanic Caucasian infants with vitamin D in infants in Houston, Texas.
We measured cord serum 25(OH)D levels, bone mineral content (BMC), bone mineral density (BMD) and their changes over 3 months of life with 400 IU/day of vitamin D3 supplementation.
Cord serum 25(OH)D was significantly lower in Hispanic than non-Hispanic Caucasian infants (16.4 ± 6.5 ng/mL, n = 27, vs 22.3 ± 9.4 n = 22, p = 0.013). Among 38 infants who completed a 3 month vitamin D supplementation intervention, provision of 400 IU/day of vitamin D increased final 25(OH)D to a higher level in non-Hispanic Caucasian compared to Hispanic infants. There was no significant relationship between cord serum 25(OH)D and BMC or BMD in the first week of life (n = 49) or after 3 months of vitamin D supplementation.
Low cord 25(OH)D levels are seen in Hispanic infants, but their functional significance is uncertain related to bone health in a southern US setting. Daily vitamin D intake of 400 IU during the first months of life appears adequate to increase serum 25(OH)D and support BMC increases despite low initial 25(OH)D levels in some infants.

Caucasian Before 23 ng, after 38 ng, change 15 ng
Hispanic Before 17 ng, after 31 ng, change 14 ng
It appears that both increased a similar amount
Had started from and reached different levels.
We assume that breast milk provided little vitamin D
Perhaps the reason for low increase in Bone Mineral Content was that the infants lacked co-factors of vitamin D needed to build bones
Magnesium, vitamin K2, Boron, Strontium, Zinc, Silicon

- All items in category Infant-Child and Vitamin D
- Recommend 100 IU of vitamin D per kg of infant weight in Poland – July 2011
- 400 IU vitamin D daily was enough for most infants – Jan 2011
- Infants getting 1400 IU vitamin D weekly grew better – May 2011
- 400 IU vitamin D for breastfed - American Association of Pediatrics - Feb 2012
- A Finland study tried 2,000 IU dose for CHILDREN (10,000 children!)
They reported a significant decrease in type I diabetes decades later - NO toxicity, hypercalification, etc. etc.!
