IQ levels around the world are falling (perhaps lower Vitamin D, Iodine, or Omega-3)
What's Driving the Decline in IQ Scores? Mercola June 2018
Mercola postulates that GLOBAL IQ decline is due to increases in
Fluoride – seems unlikely since most countries do not use Fluoride
Flame retardants s-eems unlikely since most countries do not use them
Pesticides – seems unlikely since pesticide use has DECREASED in recent decades
Chemical exposures to children
VitaminDWiki: Perhaps due to Reduced Vitamin D
Poor cognition 26 percent more likely if low Vitamin D (29 studies) – meta-analysis July 2017
Alzheimer’s patients 3X more likely to have a malfunctioning vitamin D receptor gene – 2012
Cognitive decline with age – and lower Vitamin D
Some people with lower vitamin D levels have lower IQ, mortality, etc.

Types of evidence that Vitamin D helps brain problems - 2014
VitaminDWiki: Perhaps due to Reduced Iodine
Iodine levels have been decreasing and low Iodine is associated with less cognition
Vitamin D and Iodine are similar, and both are deficient and important to health
VitaminDWiki: Perhaps due to Reduced Omega-3
Infants getting 1 g of Omega-3 for 12 weeks got better brains – RCT March 2017
Adding Vitamin D, Omega-3, etc to children’s milk improved memory (yet again) – RCT June 2018
Omega-3 found to treat Alzheimer’s and Parkinson’s in animals – Sept 2017
Cognitive Impairment 1.8 times more likely if low Omega-3– Oct 2016
Preterm birth extended by 2 weeks with Omega-3 – Meta-analysis Nov 2015
Cognitive decline in elderly slowed by Omega-3 – meta-analysis May 2015
Omega-3 – fewer than 5 percent of adult women get the RDA – April 2018
Far less Omega-3 and far more Omega-6 in recent decades
VitaminDWiki: Perhaps due to reductions in BOTH
Adding Vitamin D, Omega-3, etc to children’s milk improved memory (yet again) – RCT June 2018
Omega-3 and Vitamin D each treat many mental health problems - April 2018
Vitamin D, Omega-3 supplementation helps cognition – perhaps due to serotonin – Feb 2015
Depression – is it reduced by Vitamin D and or Omega-3 – RCT 2019
Typical pregnancy is now 39 weeks – Omega-3 and Vitamin D might restore it to full 40 weeks
NAFLD in children nicely treated by combination of Vitamin D and Omega-3 – RCT Dec 2016
Improve Cognitive Health and Memory with Vitamin D and Omega-3 – World Patent March 2018
