- Irritability and hyperactivity were common in children with ASD.
- Vitamin D and omega-3 reduced irritability symptoms in children with ASD.
- Vitamin D reduced hyperactivity symptoms in children with ASD
1 year trial
It is doubtful that the 2,000 IU dose would have resulted in a 40 ng level, the minimum found to be needed by many other studies
Interesting: Omega-3 boosted Vitamin D response
"Serum 25(OH)D concentration (nmol/L) increased by 27±14 in VID and by 36±17 in VIDOM groups.."
Autism category in VitaminDWiki starts withAutism category has
- Most Autism Risk factors are associated with low vitamin D - March 2014
- Rickets – 26 percent had autism: no rickets, no autism (both associated with low vitamin D) – June 2015
- Premature birth 2.5X more likely if mother had low vitamin D and was having twins – July 2013
- Autism 3X more likely after closely spaced pregnancy vs 3 year apart– Jan 2011
- Having twins takes more vitamin D - May 2011
Autism treated by Vitamin D
- Autism treated by Vitamin D (monthly injection of 150,000 IU) – June 2017
- Autism decreased in 8 out of 10 children supplemented with vitamin D – April 2015
Autism reduced by vitamins before and during pregnancy
- Autism risk reduced 2X by prenatal vitamins (Vitamin D or Folic) – Feb 2019
- Women who had supplemented with any vitamins were 6 X less likely to have autistic offspring – Jan 2018
- Autism rate cut in half when multivitamins (including vitamin D) used during pregnancy – Oct 2017
- Autism rate in siblings reduced 4X by vitamin D: 5,000 IU during pregnancy, 1,000 IU to infants – Feb 2016
Autism and Vitamin D Receptor (not enough Vit D to the tissues)
Autism - other risk factors
- Autistic symptoms reduced by Vitamin D and or Omega-3 – RCT March 2019
- Omega-3 probably can decrease Autism and ADHD – March 2019
- Autism risk increased if infant had antibiotics (2X), acetaminophen (3X), or no vitamin D drops (1.5X) – June 2018
- 20 X more Parkinson's and 100X more Autism with GMO soy in China
- Note >100X increase in Autism while having GMO soy in the US
Vaccines increase the risk
- Does a vaccine increase the risk of Autism – March 2019
- Autism 2.75 X more likely in Hib vaccines containing Mercury – May 2018
- Autism and ADHD type disorders were 14X more likely in survey of extreme preterm vaccinated infants - April 2017
- Off topic: CDC deleted a 3X increase in black male autism due to vaccination – whistle blowing Aug 2014

Irritability and hyperactivity are common in children with Autism Spectrum Disorder (ASD). Because pharmacological treatments may have adverse effects, and despite limited evidence, caregivers/parents often use dietary supplements such as vitamin D and omega-3 fatty acids to address these behavioural symptoms. As a secondary objective of the VIDOMA (Vitamin D and Omega-3 in ASD) trial, we evaluated the efficacy of vitamin D, omega-3 long chain polyunsaturated fatty acid [omega-3 LCPUFA; docosahexaenoic acid (DHA)], or both on irritability and hyperactivity. New Zealand children with ASD (aged 2.5-8 years) participated in a 12-month randomized, double-blind, placebo-controlled trial of vitamin D (2000 IU/day, VID), omega-3 LCPUFA (722 mg/day DHA, OM), or both (2000 IU/day vitamin D + 722 mg/day DHA, VIDOM).
The primary outcomes were the Aberrant Behaviour Checklist (ABC) domains of irritability and hyperactivity. Biomarkers (serum 25-hydroxyvitamin D 25(OH)D and omega-3 index) and primary outcomes were measured at baseline and 12-months. Out of 111 children who completed baseline data collection, 66% completed the study (VID = 19, OM = 23, VIDOM = 15, placebo = 16).
After 12 months, children receiving OM (-5.0 ± 5.0, P = 0.001) and VID (-4.0±4.9, P = 0.01) had greater reduction in irritability than placebo (0.8±6.1).
Compared to placebo, children on VID also had greater reduction in hyperactivity (-5.2±6.3 vs. -0.8±5.6, P = 0.047). Serum 25(OH)D concentration (nmol/L, mean±SD) increased by 27±14 in VID and by 36±17 in VIDOM groups (P < 0.0001), and omega-3 index (%, median (25th, 75th percentiles)) by 4.4 (3.3, 5.9) in OM and by 4.0 (2.0, 6.0) in VIDOM groups (P < 0.0001), indicating a good compliance rate.
The results indicate that vitamin D and omega-3 LCPUFA reduced irritability symptoms in children with ASD. Vitamin D also reduced hyperactivity symptoms in these children.
