  • FACT: Studies have shown many associations between 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

7 studies: Autism reduced by Omega-3

Summary of this page by CHAT-GPT-4 Sept 2023


  • Many studies have shown associations between autism and low Vitamin D levels.
  • Clinical trials have shown that Vitamin D during pregnancy can prevent Autism.
  • Clinical trials have also treated autism in children with Vitamin D.
  • The recommendation is to take extra vitamin D when pregnant. While there's a small risk in taking vitamin D during pregnancy, the risk of not doing so is significant, especially if you already have an autistic child.

Highlighted Studies and Information:

  • Autism was 20X more likely if acetaminophen (Tylenol) was used from age 12 - 18 months (July 2023).
  • There were over 200 studies suggesting a link between vaccines and autism as of 2023.
  • The US saw an explosion of autism cases, with the cost associated with autism reaching $223 billion/year in 2020.
  • Almost 7% of 8-year-old boys in California had autism in 2020, with males being 3.8X more likely to have autism than females.
  • Autism symptoms, in some cases, disappeared by changing the diet.
  • A 3X increase in autism in boys by age 3 was observed if they had 3 hours of daily screen time before age 1 (potentially due to less vitamin D exposure) as of Feb 2022.
  • Autism may be synergistically treated by Vitamin D and probiotics (July 2022).
  • Autism was 2X to 3X more likely if there was a poor Vitamin D Receptor (June 2020).
  • Vaccinations resulted in increased office visits for children 16 months later (Nov 2020).
  • Dr. Cannell, who is associated with the Vitamin D Council, has written and spoken extensively about the relationship between autism and Vitamin D. He suggests that autism can be treated with Vitamin D levels between 80 – 120 ng.

Autism treated by a combination of Vitamin D plus Omega-3 - case report 2020

Omega-3 PUFAs and vitamin D co-supplementation as a safe-effective therapeutic approach for core symptoms of autism spectrum disorder: case report and literature review
Nutritional Neuroscience. An International J. on Nutrition, Diet and Nervous System. Vol 23, 2020 - Issue 10 https://doi.org/10.1080/1028415X.2018.1557385

Introduction: Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders characterized by abnormal development of cognitive, social, and communicative skills. Although ASD aetiology and pathophysiology are still unclear, various nutritional factors have been investigated as potential risk factors for ASD development, including omega-3 polyunsaturated fatty acids (PUFAs) and vitamin D deficiency. In fact, both omega-3 PUFAs and vitamin D are important for brain development and function.

Case report: Herein, we report the case of a 23-year-old young adult male with autism who was referred to our Unit due to a 12-month history of cyclic episodes of restlessness, agitation, irritability, and oppositional and self-injurious behaviors. Laboratory tests documented a markedly altered omega-6/omega-3 balance, along with a vitamin D deficiency, as assessed by serum levels of 25-hydroxyvitamin D. Omega-3 and vitamin D co-supplementation was therefore started, with remarkable improvements in ASD symptoms throughout a 24-month follow-up period. A brief review of the literature for interventional studies evaluating the efficacy of omega-3 or vitamin D supplementation for the treatment of ASD-related symptoms is also provided.

Conclusion: To our knowledge, this is the first case reporting remarkable beneficial effects on ASD symptoms deriving from omega-3 and vitamin D combination therapy. This case report suggests omega-3 and vitamin D co-supplementation as a potential safe-effective therapeutic strategy to treat core symptoms of ASD. However, larger studies are needed to evaluate the real efficacy of such therapeutic approach in a broader sample of ASD patients.

Autism Tsunami: the Impact of Rising Prevalence on the Societal Cost of Autism in the United States - May 2021
Journal of Autism and Developmental Disorders May 2021 https://doi.org/10.1007/s10803-021-05120-7
Mark Blaxill • Toby Rogers • Cynthia Nevison

The cost of ASD in the U.S. is estimated using a forecast model that, for the first time, accounts for the true historical increase in ASD. Model inputs include ASD prevalence, census population projections, six cost categories, ten age brackets, inflation projections, and three future prevalence scenarios.
Future ASD costs increase dramatically: total base-case costs of

  • $223 (175-271) billion/year are estimated in 2020;
  • $589 billion/year in 2030,
  • $1.36 trillion/year in 2040, and
  • $5.54 (4.29-6.78) trillion/year by 2060,

with substantial potential savings through ASD prevention. Rising prevalence, the shift from child to adult-dominated costs, the transfer of costs from parents onto the government, and the soaring total costs raise pressing policy questions and demand an urgent focus on prevention strategies.

A modern day witch trial substack by Rogers in May 2023

  • "The titans of the autism industry have officially banned any discussion of the prevalence, causes, and costs of autism in order to continue profiting from the mass poisoning of children."
  • "A societal cost of autism model (or really any cost of disease model) is pretty straightforward. One just has to calculate the prevalence of the condition in the population and then estimate the costs across several categories — lost parental wages, lost personal wages (for the person with the condition), educational costs, healthcare costs, supportive services (particularly housing) costs — and then just multiply the number of people afflicted times the average cost per person to come up with a number for the whole society."

Almost 7% of 8-year-old California boys (1 in 15) had Autism in 2020 (males 3.8X that of females)

Autism and Dr. Cannell (who is Autistic) at the Vitamin D Council (closed ~2018)

  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."

    Is it Time to Give Up on a Single Diagnostic Label for Autism? Scientific American May 2018

    +"That was the ruling by the editors of the authoritative Diagnostic and Statistical Manual in 2013, but it remains controversial" +"All autistic individuals share core features, including social and communication difficulties, unusually narrow interests, a strong need for repetition and, often, sensory issues. Yet these core features vary enormously in how they are manifested and in how disabling they are." +"There are huge disparities in many areas, such as language development or IQ, and in the presence or absence of co-occurring medical conditions and disabilities"

    • The Vaccine Act has a 3-year statute of limitation, and virtually all Autistic behavior is not detected until after the 3-year limitation
    • The one case in which Autism did start within the 3-year time limit was conceded by the govt (and the evidence was sealed), but the 5,500 other Autism claims were thrown out

    • 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."

    Many autism symptoms disappear by changing the food

    Fever Benefits for Autism in a Food Video and Transcript -Dr. Greger March 2021
    Nobel Prize for Medicine for brain ailments went to the “father of fever therapy,”
    When the brain gets too hot, it generates heat shock proteins to protect itself
    sulforaphane, the active ingredient in cruciferous vegetables such as broccoli, kale, and collard greens, activates the heat shock response.
    His 2nd video on Autism and Food points out that four different aspects of Autism are treated by sulforaphane

    • shock proteins are released to boost synaptic transmission,
    • Nrf2 is activated to wipe out the free radicals,
    • mitochondrial function is restored,
    • suppress the inflammation triggered by NF-kappa-beta

    Broccoli Compound Eases Autism Symptoms by Mimicking a Child's Fever HealthLine, 2014?
    "During the 18-week study, between 35 and 60 percent of those taking sulforaphane showed decreases in characteristic autism symptoms like repetitive movements, irritability, hyperactivity, and communication problems. "

    A Randomized Controlled Dietary Trial for Autism June 2021, Dr. Greger
