Autism: Will vitamin D supplementation during pregnancy and early childhood reduce the recurrence rate of autism in newborn siblings?

Stubbs G1, Henley K2, Green J2.


Vitamin D deficiency is widespread in the world including the vulnerable group of pregnant women. Vitamin D deficiency during pregnancy is hypothesized to contribute to the cause of autism. Further, it is hypothesized that vitamin D supplementation during pregnancy and early childhood will reduce the recurrence rate of autism in newborn siblings.

To investigate the hypothesis an open label prospective study was performed prescribingvitamin D during pregnancy to mothers of children with autism at a dose of 5000IU/day. The newborn siblings were at high risk for the recurrence of autism. The newborn infants were also prescribed vitamin D, 1000IU/day to their third birthday. The newborn siblings were followed for three years and during that time, were assessed for autism on two separate occasions: at 18months and 36months of age. The results were compared to the reported recurrence rates in siblings of autistic children in the literature.

The final outcome was 1 out of 19 (5%) developed autism in contrast to the recurrence rate of approximately 20% in the literature. We did not have a control group, nor was there blinding.

The results are promising, however, this is a preliminary study with very small numbers and was uncontrolled. Further study with larger numbers is indicated. The ethics of prescribing a low dosage of vitamin D such as 400IU D3/day to a control group of mothers in comparison to a large dosesuch as 5000IU D3/day are problematic in our opinion.

Jeff T Bowles: Being the author of the best-selling book on Vitamin D3 in the world, and given the topic of the book was the miraculous results of my one year experiment of taking HIGH DOSES of vitamin D3, puts me in the unique position of being the sounding board for many hundreds if not a few thousands of others who have embarked on their own high dose vitamin d3 experiment. Nobody on planet earth has this amount of unusual and exciting knowledge, and I will be sharing it with you in this series of 100 short articles describing a disease and some sort of amazing result achieved with high dose D3 therapy.

Sincerely Jeff T. Bowles
