Vitamin D is now beneficial to the brain as well.

  

Elderly persons can still benefit greatly from high blood levels of vitamin D, which can slow down the process of cognitive decline in their brains.

Researchers have discovered that high vitamin D levels help those suffering from dementia, particularly the elderly, and slow down the process of cognitive deterioration.

This research was done at Tufts University and other American universities, and the Journal of Alzheimer's Association published the findings.

The basic lesson is that as we age, our brains can benefit from certain foods, particularly vitamins. It is abundant in milk, orange juice, and oily fish. The skin also absorbs sunshine to create vitamin D.

However, a growing corpus of research and data from brain samples support the idea that vitamin D is good for brain function. Brain tissue from a total of 209 subjects was thoroughly examined in this study on aging and memory. In 1997, this investigation was initiated. It was discovered that the abnormalities that begin to appear in the brain's cells and tissue as we age can still be seen in the afterlife.

Examining the four brain regions where vitamin D was acting, the researchers found that two of these regions were associated with Alzheimer's disease, one with brain blood flow and dementia, and a fourth showed no signs of excess or deficiency in vitamin D. However, they also discovered that the region of the brain with the highest level of vitamin D showed slightly less deterioration than the other three.

In other words, vitamin D enhances mental functions such as memory and general memory. The scientists themselves are unsure, and further investigation will be conducted in the upcoming stage. But the experts issued a warning. Vitamin D supplements should not be used carelessly; instead, healthy individuals should take up to 600 IU daily, and senior citizens, up to 800 IU daily.
