Less pollution ==> more UVB getting to the ground ==> more vitamin D when skin is exposed in middle of the day
Less pollution ==> People outdoors more ==> more vitamin D the sun when skin is exposed in middle of the day
Overview Alzheimer's-Cognition and Vitamin D starts with
- FACT: Cognitive decline is 19X more likely if low vitamin D
- FACT: Dementia is associated with low vitamin D levels.
- FACT: Alzheimer’s Dementia 2.3X more likely in elderly if low vitamin D – Dec 2022
- FACT: Dementia is associated with low vitamin D - many studies
- FACT: Alzheimer's Disease is 4X less likely if high vitamin D
- FACT: Every single risk factor listed for Alzheimer's Disease is also a risk factor for low vitamin D levels
- FACT: Elderly cognition gets worse as the elderly vitamin D levels get even lower (while in senior homes)
- OBSERVATION: Reports of increased vitamin D levels result in improved cognition
- OBSERVATION: Alzheimer’s patients 3X more likely to have a malfunctioning vitamin D receptor gene – 2012
- OBSERVATION: Alzheimer's Disease has been seen to halt when vitamin D was added.
- OBSERVATION: Alzheimer’s is associated with all 7 of the genes which restrict vitamin D
- OBSERVATION: 39 vitamin D and Alz. or Cognition intervention trials as of Sept 2018
- OBSERVATION: 2 Meta-analysis in 2012 agreed that Alzheimer's Disease. associated with low vitamin D
- OBSERVATION: 50X increase in Alzheimer's while decrease in vitamin D
- OBSERVATION: Vitamin D reduces Alzheimer’s disease in 11 ways
- OBSERVATION: Alzheimer’s cognition improved by 4,000 IU of vitamin D
- OBSERVATION: Plaque removed in mice by equiv. of 14,000 IU daily
- OBSERVATION: DDT (which decreases Vit D) increases risk of Alzheimer's by up to 3.8X
- OBSERVATION: 2% of people have 2 copies of the poor gene reference: Alz Org
- OBSERVATION: Genes do not change rapidly enough to account for the huge increase in incidence
- OBSERVATION: End of Alzheimer's videos, transcripts and many studies protocol has been very successful
- It adjusts Vitamin D, B-12, Iron, Omega-3, food, etc, and can now be done at home.
- FACT: Vitamin D is extremely low cost and has very very few side effects
- CONCLUSION: Everyone concerned about cognitive decline or Alzheimer's Disease should take vitamin D
- PREDICTION MET: By 2024 Omega-3 and high dose Vitamin D will be found to reverse Alzheimer's in humans
There are 13+ Alzheimer’s meta-analyses in VitaminDWiki
There are 97+ Alzheimer’s studies in VitaminDWiki
Dementia is associated with low vitamin D - many studies 50+ studies
16+ studies in both categories Cognitive and Omega-3
Air Pollution reduces Vitamin D production - many studies has the following:
Fact: Pollution reduces the amount of time that people are outdoors
Fact: Pollution is often associated with hot temperatures - another reason to not go outdoors
Fact: Less time outdoors results in lower Vitamin D levels
Fact: Pollution attenuates the amount of UVB getting to the skin (but by only a few percent)
Fact:The body's ability to fight Irritation/Inflammation is aided by vitamin D
Fact: All of the types of PM2.5 deaths are also associated with low vitamin D
Most air pollutions reduce Vitamin D (PM2.5 is worst) – June 2021
Conclusion: Vitamin D supplementation helps the body fight the effects of pollution.
- There were 60+ references in Air Pollution reduces Vitamin D page as of June 2023
- Inhaled vitamin D might turn out to be especially good form as it goes directly to the lungs.
- The Evidence is strong: Air pollution seems to cause dementia (perhaps low Vitamin D) – May 2019
- Air pollution associated with 45 percent increased risk of Vitamin D deficiency while pregnant – Aug 2019
- PM2.5 pollution associated with 9 types of deaths (all associated with low Vitamin D) – Nov 2019
