Most of the world considers repletion level to be 30 ng
- Fewer infants were vitamin D deficient when they got 800 IU – RCT Feb 2014
- Third study found that Infants needed 1600 IU of vitamin D – JAMA RCT May 2013
- 1000 IU vitamin D not enough in winter to restore levels in children - RCT June 2015
- UK program to increase Vitamin D (Healthy Start) continues to be a farce - Nov 2014

Introduction: Although the role of vitamin D in the prevention of rickets has long been well established, controversies still exist on the ideal dose of vitamin D supplementation in infants.
Objective: We assessed serum 25-hydroxyvitamin D (25OHD) status simultaneously in maternal and cord samples and the response to vitamin D3 supplementation in neonates.
Methods: Serum 25OHD levels were evaluated from maternal, and umbilical cord samples from term normal pregnancies. Repeat 25OHD levels were assessed in neonates with 25OHD below 30 nmol/L following vitamin D3 200 IU daily after 6 weeks.
Results: Blood samples were taken including 57 cord samples and 16 follow-up neonatal samples. Maternal and cord serum 25OHD were 43 ± 21 and 29 ± 15 nmol/L, respectively. Infants with 25OHD < 30 nmol/L (19.8 ± 4.7 nmol/L) had a significant increase in serum 25OHD (63.3 ± 14.5 nmol/L) following vitamin D3 200 IU daily after 6 weeks.
Conclusion: Healthy Irish infants born at term are at high risk of vitamin D deficiency, but vitamin D3 200 IU daily, rapidly corrects poor vitamin D status.
