Did you know?
  • Autism has seen huge increases around the world in the past few decades
  • There are many proposed reasons for the increase; including
      low Vitamin D, antibiotics, and Roundup
  • There are 27 reasons to associate Autism with low vitamin D
  • Children of women who had higher levels of vitamin D have lower risk of autism
          (More Autism info below)

  • FACT: Studies have shown many associations of autism to low Vitamin D
  • FACT: Clinical trial has prevented Autism with Vitamin D during pregnancy
  • FACT: Clinical trial has treated autism in children
  • RECOMMENDATION: Take extra vitamin D when pregnant
    There is a tiny risk in taking vitamin D during pregnancy, but a major risk in not doing so if you already have an autistic child

chart is adapted from from http://autisminnb.blogspot.com/2011/01/autism-speaks-cdc-autism-prevalence.html
Autism cases in U.S. jump to 1 in 45 Nov 2015 - based on 2014 data
In 2014, it was 75 % boys, 25 % girls.
CDC update: 1 in 88 as of 2008 Reported March 2012
This is a 78 % increase in (2003-2008) for ALL children
110% increase for Hispanics, and 91% increase for black children (2003-2008) (dark skin strongly points to vitamin D)
CDC PDF of 2008 study which was finally published in 2012 is attached to the bottom of this page
Prevalence of Autism Spectrum Disorder Among US Children and Adolescents, 2014-2016 JAMA 2018
Leveling out? 1.46% (1 in 68) based on survey of parents - has child been diagnosed with Autism
1 child in 68 CDC March 2014
An increase of about 30% from 2008 to 2010, which is also an 120% increase in decade since 2000/2002

Autism prevalence


Recent Autism items by Dr. Cannell of the Vitamin D Council

  1. Both have strong inheritance features – Vitamin D about 60%
  2. Both have gotten substantially worse in last 30 years
  3. Vitamin D is known to be involved in brain development
  4. All autistic children are VitD deficient, but not all children who are deficient are autistic: genes are involved
  5. When giving vitamin D to cure children of rickets “mental dullness” decreases as well
  6. Children with genes which give them too much (Williams Syndrome) have to reverse of autism – too sociable
  7. Mothers having lots of fish (and thus more vitamin D) give birth to kids with less autistic symptoms
  8. Both associated with weak bones
  9. Both worse around the age of weaning
  10. Autism is more common in rich families – more likely to apply sun screen and stay indoors
  11. Autism increases with drugs which lower levels of vitamin D
  12. Seizures are common with Autism - Vitamin D has been shown to reduce seizures
  13. Fewer autistic symptoms (such as sleep problems) during summer: when child gets more vitamin D from the sun
  14. Both worse with latitude
  15. Both vary with Ultraviolet light
  16. Both vary with time of year (more birth of autistics in March in Northern hemisphere)
  17. 2X more urban autism – less UVB in urban environments
  18. Both worse with pollution
  19. Both worse with increased clouds and rain
  20. Both worse with closely spaced pregnancies
  21. Autistics have abnormal immune response – similar to that of vitamin D deficiency
  22. Low levels of vitamin D in mother animals reduces brain function in offspring
  23. Vitamin deficient rat pups have similar brain abnormalities to that of human autistic children
  24. Autistic children get less vitamin D in their blood for the same amount of sun exposure
  25. The 4 males/1 female ratio - Note estrogen increases vitamin D in the brain (testosterone does not)
  26. Both worse in African Americans (A-A 2-3 increased autism rate)
  27. Both worse in Dark-skinned immigrants in Europe


  • Animal study finds that suggests vitamin D may help prevent and treat autistic symptoms Vitamin D Council Feb 2016
    ". . . "if you want your children to be free of autism, we recommend both mom and dad supplement with 5,000 IU/day of vitamin D for at least 3 months before conception (this dose will also improve both male and female fertility). Then, the pregnant woman should remain on 5,000 IU/day, and perhaps 10,000 IU/day, which is the No Observed Adverse Effects Level (NOAEL) level for vitamin D intake throughout her pregnancy."
    "After the child is born, he or she should supplement with at least 1,000 IU/25 pounds of body weight per day. When the child reaches 125 pounds, he or she should take 5,000 IU/day. If the child shows any signs or symptoms of autism, the dose should be increased to 2,000 IU/per day/per 25 pounds of body weight."

  • Why It’s So Difficult to Diagnose Autism in Girls Slate Oct 2015
    "Some researchers theorize that girls are better than boys at camouflaging their symptoms, particularly during highly structured interactions such as clinic visits. For instance, a colleague of mine described girls with autism as “caricatures” in social interactions. These girls may be motivated to interact, but their behaviors seem exaggerated."
