Note: this study did not apparently consider genes which reduce vitamin D getting to tissues
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. $75/month.
- 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

A vast majority of the elderly population shows a mild to moderate vitamin D deficiency. Besides the well-known function of vitamin D, vitamin D receptor is also expressed in brain and is discussed to regulate several genes. However very little is known whether genes are regulated, associated with Alzheimer’s disease (AD). Here we investigate 117 genes, known to be affected in AD, in mouse brain samples with a mild vitamin D hypovitaminosis comparable to the vitamin D status of the elderly population (20%–30% deficiency). The 117 genes include two positive controls, Nep and Park7, already known to be affected by both AD and vitamin D hypovitaminosis. The 25 most promising candidates were verified in a second independent mouse cohort, resulting in eleven genes further evaluated against three additional housekeeping genes.
Three of the remaining eight significantly altered genes are involved in APP homeostasis
- Snca,
- Nep,
- Psmb5),
and each one gene in
- oxidative stress (Park7),
- Inflammation (Casp4),
- lipid metabolism (Abca1),
- signal transduction (Gnb5) and
- neurogenesis (Plat).
Our results tighten the link of vitamin D and AD and underline that vitamin D influences several genes also in brain, highlighting that a strong link not only to AD but also to other neurodegenerative diseases might exist.
