What is the link between vitamin D and dementia?

Vitamin D is essential for bone health, immune system function and other bodily functions. Around half of the population is vitamin D deficient.

This can cause a variety of health issues, such as osteoporosis and muscle weakness. It can also lead to depression. A vitamin D deficiency can increase the risk of dementia. This is a condition which affects your memory and thinking abilities.

What is Vitamin D?

Vitamin D is needed by your body to help absorb calcium and phosphorus. This helps build strong bones and tissues.

It is also important for regulating the immune system and decreasing inflammation.

Vitamin D is unique because it can be synthesized in the skin by sunlight. You can also get vitamin D by eating food such as eggs, fish, fortified milks, and juices.

Vitamin D in Dementia

Numerous clinical studies have shown a correlation between low vitamin D levels and an increased risk for dementia.

Vitamin D may help protect the brain because it reduces inflammation, promotes the growth and survival neurons, and regulates calcium levels in the mind. These processes are essential for maintaining cognitive functions and reducing dementia risk.

Vitamin D Supplements May Reduce Your Risk For Dementia

Many researchers have investigated whether vitamin D supplements can reduce the risk for dementia.

A new study, published in March 2023 , provides evidence that vitamin D supplements may be effective for preventing dementia.

The study tracked over 12,000 people who had no dementia at the beginning of the study. It found that those taking vitamin D supplements were 40% less likely to develop dementia than those who didn’t. The study also found that women were more likely to develop dementia than men, and those without mild cognitive impairment. The study found that those who did not have a particular genetic variant (APOE e4 ).) had a greater reduction in risk.

Although more research is required to confirm this finding, the study suggests that supplementing with vitamin D may be an effective and simple way to reduce dementia risk.

Supplements may not help if you do not have a vitamin D deficiency. Consult your doctor about the right dosage.
