Vitamin D:

  • Studies Have Shown That Individuals Whom Are Vitamin D Deficient Have A Substantially Increased Risk for Developing Alzheimer's and Dementia

  • Due To the Unique Way Vitamin D Vitamin D is Produced, Scientists State That The Majority Of Seniors Are Likely Deficient In Vitamin D

Vitamin D & The Brain:

Vitamin D has long been known for its importance in maintaining healthy bones. More recently, researchers have found evidence linking Vitamin D to a wide range of brain functions including learning and memory.

Vitamin D activates nerves in the brain and spine which are involved with neurotransmitter creation and nerve growth. Researchers also believe that Vitamin D protects brain neurons and reduces inflammation; inflammation is a common characteristic of Alzheimer's.

Vitamin D is one of the most important supplements to take, especially for individuals over the age of 65, because Vitamin D deficiency is linked to serious health issues and because of the unique deficiency risk discussed below.

Deficiency Risk:

Vitamin D poses a unique deficiency risk, because as we age, our bodies become less and less efficient at producing Vitamin D. Individuals over the age of 70, produce 70 percent less Vitamin D than an individual in their 20s.

Estimates place the percentage of seniors who are Vitamin D deficient at 95 percent. Individuals in climates which receive less daylight, or individuals who do not go outside often, are at an even higher risk of Vitamin D deficiency.

The Evidence, Research & Studies: 

There is a significant amount of evidence linking Vitamin D deficiency to cognitive decline, Alzheimer's, and dementia.

Two studies conducted by Neuroscientists at the Universities of Cambridge and Manchester, England examined 4,500 individuals over the age of 65 and both found that lower levels of Vitamin D were associated with worse mental performance. The study conducted at the University of Cambridge found that individuals who were severely deficient for Vitamin D had double the risk of being cognitively impaired when compared to individuals with ideal Vitamin D levels.
