A new study published in the journal Nature Medicine has found that older adults who take vitamin D supplements may be less likely to develop dementia.
The study, which was conducted by researchers at the University of California, San Francisco, followed over 2,000 older adults for an average of 7 years. The researchers found that those who took vitamin D supplements were 23% less likely to develop dementia than those who did not take supplements.
Researchers believe :
The researchers believe that vitamin D may help to protect against dementia by reducing inflammation in the brain.
Vitamin D has long been under investigation for its use in the treatment of osteoarthritis – the degenerative breakdown of cartilage and changes in the underlying bone. However, a consensus regarding the utility and mechanism of action of vitamin D in osteoarthritis has never been reached.
A recent study shows that vitamin D may have its effects on bones through sirtuin proteins, which are becoming known for their anti-aging properties.
It is important to note that this study only found an association between vitamin D and dementia. It does not prove that vitamin D supplements can prevent dementia.
However, the study does provide some encouraging evidence that vitamin D may be a beneficial supplement for older adults. If you are an older adult, talk to your doctor about whether vitamin D supplements are right for you.
Vitamin D3 Benefits are due to Sirt1 and the Vitamin D Receptor :–
Sirt1 is a protein that helps regulate metabolism and aging. It is also known as a sirtuin, which is a class of proteins that are involved in cellular repair and protection.
The vitamin D receptor (VDR) is a protein that binds to vitamin D and helps to regulate its activity. The VDR is found in many tissues throughout the body, including the brain, bones, and immune system.
When vitamin D binds to the VDR, it activates the VDR and triggers a cascade of events that lead to the expression of genes that are involved in a variety of cellular functions.
One of the genes that is activated by vitamin D is the gene that encodes Sirt1. This means that vitamin D can help to increase the levels of Sirt1 in cells.
Strong bones: Vitamin D helps to keep bones strong by increasing the absorption of calcium from the gut.
Reduced risk of cancer: Vitamin D has been shown to reduce the risk of some types of cancer, such as breast cancer and colon cancer.
Reduced risk of heart disease: Vitamin D has been shown to reduce the risk of heart disease by reducing inflammation and improving blood pressure.
Improved mood: Vitamin D has been shown to improve mood by increasing the production of serotonin, a neurotransmitter that is involved in mood regulation.
